(2) Alternate Fuels/Nitrous Injection: Simulation supports testing various fuels and nitrous-oxide injection. Cylinder pressures, including BMEP (Brake Mean Effective Pressure), are calculated and can be used to determine safe nitrous activation points and flow limits.

(3) Air-Fuel Ratio Modeling: Model any air/fuel ratio for any fuel selected. Air/Fuel ratio remains fixed throughout the rpm testing range. Also see #45 a Pro-Tool™ feature that allows the air/fuel ratio to change via a user-entered "map."

(4) Flow QuickCalculator™: Calculates the potential flow for any orifice size. Also shows restriction flow data. You can calculate the throttle size for any airflow or the airflow for any throttle dimensions. Simulation also includes a Quick Pressure-Drop Calculator that converts flow values from one pressure-drop rating to another in seconds.

(5) CamMath QuickCalculator™: The basic four valve events (IVO, IVC, EVO, EVC) are needed to pinpoint the intake and exhaust valve opening and closing points. Unfortunately, many cam catalogs and other printed materials do not provide this essential information. While these conversions can be accomplished in the CamManager™, the simple the CamMath QuickCalculator™ instantly converts the lobe-center angle, intake centerline, and the duration values into IVO, IVC, EVO, and EVC valve events.

(6) Variable Valve Timing: Many engines use variable cam timing to optimize power, economy, and other engine characteristics. You can directly model Variable Valve Timing that "switches" between two unique cam profiles when the engine reaches the activation rpm. The cam profiles for each "lobe" and the activation rpm are completely adjustable and can be included as variables in Iterative testing.

(7) One-Click Iterative Testing™: Iterative™ testing, an exclusive feature of Motion Software simulations, is an automated method of performing multiple tests and locating optimum combinations. One-Click Iterative Testing is a feature of the QuickIterator™ incorporated in all engine simulations. By simply clicking a single button, the simulation will begin a series of tests and display the best result, all without user intervention.

(8) Connecting-Rod-Length And Piston-Pin Position Modeling: Simulation incorporates models for the changes in forces against the cylinderwall and crankshaft that occur when connecting-rod length and/or piston-pin position are modified. You can directly enter any connecting-rod length or pin position for analysis. Program displays changes in power, torque, etc. Calculates the subtle changes in instantaneous piston position, piston dwell and the associated thermodynamic effects.

(9) Import Port Flow Files: Import and test flow files from virtually all Motion Software engine simulations (even older software). This makes testing and analysis much easier for those who have developed a library of data files from other simulation packages. DynoSim6 and Dynomation-6 also import Flow Pro, and other flowbench file formats.

(10) Custom Cylinder-Head Flow: Allows the direct entry of flow-bench data, permitting accurate modeling of any cylinder head port flow. Cylinder-head flow files are supplied with the simulation and can be saved and loaded. Also load FlowPro and other flowbench files. Many cylinder head flow files can be found on the Internet.

(11) Multi-Page Test Reports: Simulation analysis is printed in color on several pages, depending on the simulation package. Component selections, custom data (like cylinder head flow, power curves, etc.), graphic analysis, and data tables comprise some of the pages. For even more-enhanced printing, see ProPrinting.™

(12) Direct-Click™ Component Menus: A completely unique feature on all Motion Software simulation packages. Component parts are located on the left side of the main program screen and simulation results on the right. Direct-Click™ menus allow you to select any engine/vehicle component by simply clicking on it, making modifications extremely easy. This eliminates "hunting" through drop-down menus for the parts you need; just click on any component, make your selection, and see the results in seconds!

(13) Test Multiple Engines: Allows testing multiple engines at once using the multiple-document features built into the simulation. Each "open" simulated engine is available for analysis. It can be brought into focus by simply clicking a tab located at the bottom of the screen. This professional feature saves time, eliminates opening-and-closing multiple simulation files, and permits rapid side-by-side comparisons.

(14) Cam Manager™: A comprehensive tool for entering, displaying, and modifying valve event timing and valve lift, or what Motion Software refers to as "10-point timing." Graphics show the effects of duration, lift, and lifter acceleration for both seat-to-seat and 0.050-inch valve-timing specifications. Sophisticated algorithms calculate lifter acceleration. Save and load CamFiles (many CamFiles are supplied with the simulation and many more are available on an optional CamDisk CD, available from Motion Software, Inc.).

(15) Import "10-Point" CamData™ Files: The simulation will read Motion CamFiles™ that contain not only valve timing events, lift, and camshaft type, but also cam manufacturer application data, engine family recommendations, web-site contact data, and more. All engine simulations are supplied with a basic set of CamFiles, and more are available from on separate CamDisk CD libraries. Allows rapid location of optimum camshaft timing for any application.

(16) On-Graph Comparisons Of Multiple Simulations: Compare up to four "open" simulations side-by-side on any of the graphic display. Comparisons consist of any simulation variable, such as horsepower, torque, engine pressures, engine rpm, VE, port pressures, and much more.

(17) One-Click Quick-Compare™: A time-saving feature that allows you to instantly establish a baseline engine curve and perform a side-by-side comparison with a single mouse click. This is the fastest way to test component changes and view how they alter engine performance.

(18) Automatic Software Updates: All Motion simulations support automatic updates distributed via the Web. Periodically our simulations check our servers for new program updates and automatically download and install the software. This process requires little user intervention. Automatic updating ensures that you are always running the latest simulation technology!

(19) Real-Time "What-If" Testing: All Motion simulations show components on the left side of the main program screen and display simulation results on the right. In addition, the simulations are optimized to minimize simulation calculation times. The combination of these two features allow you to analyze more components, more quickly, and instantly see the results in graphs and tables. This exclusive design sets the standard for interactive, "What If" testing.

(20) U.S./Metric Units: Allows switching between U.S. or Metric units. All component values shown on screen are instantly updated.

(21) Wave-Assisted Simulation: This simulation uses wave dynamics analysis to improve its accuracy in predicting mass flow through the intake and exhaust passages. The greater the accuracy in these mathematical calculations, the greater the overall accuracy of predicted power from the combination of components and specifications used to build the engine.

(22) Low-Cost Simulation For Enthusiasts: Our Sim-Series was developed for the dedicated engine enthusiast with a limited budget or a limited interest in building custom cylinderheads or ports (if you need these features, consider Dynomation6). Sim-Series simulations (especially DynoSim6) are powerful and easy-to-use software simulations that will help you find the best components and engine specs for your specific application. DynoSim6 can test and locate optimum cam timing, valve sizes, intake manifolds, throttle sizes, mufflers or headers, fuel choices, nitrous systems, turbos, blowers, intercoolers, and much more. Use built-in Iterator™ testing to run hundreds or thousands of tests automatically and pick the best results based on your testing criterion. DynoSim6 will help you build the "ultimate" engine without breaking your budget.

(23) Transparent 3D-Engine Pressure-Analysis Display: DynoSim6 and Dynomation-6 include a unique way to visualize the motion of pressure waves within a running engine. A cutaway view of a engine, rendered in real time, synchronizes valve and piston motions to the pressure-crank angle diagrams. As you move the crank-angle reticule across the diagram—to any crank angle within the 720 degrees of the 4-cycle process—the motion of the pistons, valves, and pressure waves are displayed in the 3D model. This feature allows you to "see inside" the running engine, offering unique insight into pressure-waves and particle flows. An excellent tool for teaching and learning engine theory.

(24) Expanded Units System (Hybrid Mode): Allows switching between U.S. or Metric units. All component values shown on screen are instantly updated to the newly selected units system. In addition, a Hybrid Units mode is provided that displays all components in Metric Units while maintaining Power and Torque and Airflow in US Units. This is common practice in some countries since Horsepower, Ft-Lbs, and CFM are commonly used units in engine literature and design.

(25) Advanced Compression Ratio Calculator: Easy-to-use, intuitive selections make calculating compression ratio a snap. Enter known values or measured volumes and instantly see the exact compression ratio for any engine. Pass computed values to the simulation with a mouse click.

(26) Model Non-SAE (Metric) Cam Timing: Sophisticated built-in calculator that will determine the SAE-equivalent timing for any cam using non-standard lift heights for valve events (0.006-inch and 0.050-inch for Primary and Secondary lift heights). Calculator first constructs a mathematical model of the non-standard cam, and then use that model to measure the SAE lift points along the calculated lift curve. This handy tool lets you to accurately model any cam for any engine, regardless of the manufacturer or country of origin.

(27) Forced-Induction Modeling: Adds sophisticated turbocharger, roots and centrifugal supercharger modeling. Determines and displays manifold pressures, belt ratios, pressure ratios, A/R ratios, intercooler efficiency, and more! Also includes wastegate modeling and throttle position modeling (before or after the compressor).

(28) Model Ignition Point And Advance: Adds ignition timing modeling that determines Mean-Best-Torque with least Advance. Ignition timing can be modified and advance-curves defined. Ignition timing is derived from the burn model applied during combustion-chamber selection. Chamber design, fuel type, A/F ratios, and more are included in ignition timing models. Clicking a checkbox in the Combustion Category instructs the simulation to derive an optimum ignition-advance curve (this feature can be used to "eliminate" ignition timing based fluctuations in engine output, making it easier to tune other engine components).

(29) ProIterator™: Iterative™ testing, an exclusive feature of Motion Software simulations, is an method of performing multiple tests and locating optimum combinations, automatically. The ProIterator, a ProTools™ feature, provides maximum flexibility in selecting components and setting up the desired testing criterion. Search for optimum power or torque, or locate the component combinations that produce maximum "area-under-the-curve" for horsepower or torque. Once you have established your testing criterion, the ProIterator will begin a series of tests and display the best 10 results, all without user intervention.

(30) Extended Color Display: Allows user selection of various color schemes for the main interface.

(31) Extended-Data Displays: This professional feature is part of the ProTools™ kit (included with DynoSim6 and Dynomatioin6; exclusive features of Motion Software, Inc). Professionals often need additional data beyond power, torque, and other "basic" measurements to optimize engine performance. To provide this data, internal physics models are extended, and "in-depth" data is calculated and displayed in graphs and table-based displays. Extended data types depend on the simulation, but examples include various engine pressures, frictional and pumping power losses, mass flow into the cylinders, exhaust gas charge spoilage, and more.

(32) ProPrinting™ Presentation Reports: This is a professional feature available in the ProTools™ kit (included with DynoSim6 and Dynomation6; exclusive features of Motion Software, Inc). ProPrinting generates custom, full-color, multi-page test reports, including cover pages, tables of contents, your name and/or company name and logo, and even an optional glossary. ProPrinting produces an easy-to-read, professional printed test report that you will be proud to display, or present to your customers.

(33) ProData™ Graphic Displays And Tables: This is a professional feature available in the ProTools™ kit (included with DynoSim6 and Dynomation6; exclusive features of Motion Software, Inc). Includes the display of additional simulation data, often needed by professional racers and/or engine developers. The ProData Tables display charge-flow losses, cylinder trapped mass, and additional simulation results in an easy-to-read, rpm- and crank-angle-based data tables.

(34) Graph DataZones™: This is a professional feature available in the ProTools™ kit (included with DynoSim6 and Dynomation6; exclusive features of Motion Software, Inc). Graph DataZones allow the display additional graph data and/or show ranges for target data values. DataZones can clearly illustrate dangerously high pressures, engine speeds, or almost anything you wish to highlight in addition to the standard data graph lines. DataZones can be displayed in any color(s), and you can automatically select a gradient range between beginning and ending color bands.

(35) Analyze Area Under Data Curves: Part of the ProIterator™ feature set included in the ProTools™ kit (included with DynoSim6 and Dynomation6; exclusive features of Motion Software, Inc). While peak values of torque or horsepower focus on the "absolute maximum," the areas under the curves indicate the greatest "volume" of power or acceleration. Think of this area as the maximum horsepower throughout the rpm range (or torque over time). The ProIterator can search for the 10 best combinations that produce the greatest area under any portion of a selected data curve.

(36) Import CamPro, CamProPlus, S96, and CamDoctor Cam-Profile Files: DynoSim6 and Dynomation-6 support the direct import of a number of commonly used cam-profile formats, including CamPro, CamPro+, S96, Cam-Doctor, and other files, including ECM, a Motion specific format for Comp Profile files. A full featured import dialog helps you assign centerline values, set intake and exhaust lobes, and determine valve-open duration.

(37) Variable Resolution Simulation: DynoSim6 includes an FE Integration selection that sets the "mathematical depth" of the simulation with Normal, Advanced, and Extended converge modes. A similar selection in Dynomation-6 (called Wave-Action Mode) sets the calculation mesh size within engine passages (the intake and exhaust passages are divided into small volumes, called meshes, of equal size). The smaller the mesh size, the more rigorous the mathematical analysis. In many cases, the standard Normal mesh is sufficient for most engine simulations. But, in some cases, a more thorough analysis is required to overcome instabilities or odd pressure-wave interactions. This analysis is provided in the Fine and Optimized resolution modes.

(38) Imports Dynomation and DynoSim (and earlier version) Engine Files: DynoSim6 and Dynomation-6 can import many engine file formats, allowing anyone that has upgraded from virtually any Motion engine simulation released over the last 20 years to easily import their engines to begin a more rigorous analysis in the new Version-6 simulations.

(39) Air-Fuel Ratio Vs. Rpm Modeling: This is a ProTools™ feature (included with DynoSim6 and Dynomation6). Models changing air/fuel ratios throughout the rpm band by simply entering the desired air-fuel ratio values in an fuel-ratio "map" table.

(40) Engine Mass Flow Analysis: This is a ProTools™ feature (included in Dynomation6 only). This displays the mass flow into and out of the cylinders, including charge loss to exhaust (unburned charge leaving the cylinder with exhaust flow), reversion loss (from charge moving back into the intake track), and total charge lost (total charge that moved into the cylinder but was lost from all effects).

(41) Full Wave-Action Simulation Accuracy: Finite-amplitude, wave-dynamics analysis using the Method-Of-Characteristics mathematical models are exclusive features of Dynomation-6. These processes simulate the complex interactions of pressure waves in the intake and exhaust passages. Since pressure waves significantly affect the mass flow characteristics within engine passages, a comprehensive analysis of these pressure pulses is computed and made available to the user for tuning. The wave-action dynamics calculated in Dynomation-6 is one of the reasons this simulation is considered highly accurate within a wide range of 4-stroke engines.

(42) Aimed At Pro Engine Shop/Builder: Dynomation-6 was built for the engine designer and high-performance engine builder. While it utilizes the most comprehensive pressure-wave dynamics analysis that Motion Software offers, every aspect of the simulation was designed to simplify pressure-wave analysis and the analysis of engine components. We’ve listened to feedback from hundreds of professionals all over the world for more than 20 years, and their ideas and suggestions have been incorporated into this simulation package. If you are en engine professional, Dynomation-6 will help you do your job better! Give it a try. We’re looking forward to hearing from you, too!

(43) Modify Intake Runner Lengths And Taper Angles: Dynomation-6 allows the direct modification and tuning of intake port, runner, and plenum dimensions. The "secrets" to engine performance often lie in the subtle elements of engine design, like the interaction of pressure waves within induction passages. The Dynomation-6 lets you easily test a wide variety of runner configurations to determine not only how these elements affect engine power, but also to determine optimum dimensions for virtually any engine application.

(44) Model Bellmouth Intake Runners: Dynomation-6 give you the option to model elliptical bellmouths at the entrance of the intake runners, either at the atmospheric boundary or within the intake manifold plenum. Simply click the checkbox to "turn on" bellmouth modeling.

(45) Model Intake Manifold Plenums: Intake manifold plenum volume and its contribution to restriction can be modeled in Dynomation-6. Enter the volume directly or enter plenum dimensions and the volume will be calculated and used in the simulation.

(46) Modify Exhaust Tubing Sizes, Lengths, Tapers: Dynomation-6 you can help you design and tune a virtually unlimited array of exhaust header configurations, pipe lengths, steps, intersections, tapers, and megaphones. Run an engine test, make a quick pipe change, run a follow-up test. Compare the results using a back-to-back graphic display. You can run these evaluations nearly as fast as you can come up with ideas to test. Tune for power, more torque, street or racing, even build headers for turbos or nitrous engines. Dynomation-6 let‘s you easily explore what‘s possible at impossible speeds.

(47) Custom Exhaust Pipe Segments: Dynomation-6 provides a "palette" of 8 pipe segments (for each cylinder) that you can define as you wish. Set the dimensions and interconnections, arrange segments to model almost any style of exhaust header and collector system. If the simulation determines exhaust shock-waves are generated, a warning indicator will illuminate, letting you adjust pipe segments to reduce these flow-restricting pressure pulses. You can build simple individual pipe systems, standard 4-into-1 headers, Tri-Y designs, add steps, move pipe junctions, try different tubing sizes, modify collector lengths, add a megaphone. The exhaust modeling provided in Dynomation-6 truly let‘s your imagination run wild!

(48) Use 1 or 2 Exhaust Pipes Per Cylinder: Dynomation-6 models one or two exhaust header pipes per cylinder. A dual pipe design is sometimes used on some high-output engines that may (or may not) also have with two exhaust valves per cylinder (e.g., Rotax, Honda, etc). On most engines a single exhaust pipe is attached to a single port outlet for each cylinder (even when two exhaust valves are used on each cylinder). This addition of this specialized model allows Dynomation-6 to accurately model even somewhat-rare race engine designs.

(49) Megaphone And Normal Header Modeling: Dynomation-6 can model single or dual exhaust pipes per cylinder, "standard" headers with collectors, Tri-Y designs, and even pipes that terminate in a megaphone. All tubing lengths, diameters, and taper angles can be tuned for a variety of applications. Megaphone exhaust systems are often used in racing motorcycle applications, but are also applied to other applications.

(50) Display/Manage Exhaust Shock Waves: If the simulation determines exhaust shock-waves are generated, a warning indicator will illuminate, letting you adjust pipe segments to reduce these flow-restricting pressure pulses.

(51) Export Simulation Data/Results (Excel): Dynomation-6 can export simulation results into an Excel-readable file. You can choose to export either or both Rpm-Based and Crank-Angle-Based simulation data. Within Excel, you can graph, display, and further analyze any simulation results data, including power, torque, pressures, valve lift, and more.

(52) Expanded Camshaft Data Displays: Dynomation-6 displays more data in the user interface than our other simulations (DynoSim6 is designed to be a straightforward as possible, so some data fields are not available to maintain a less complex look).

(53) Full Sim Problem Analysis In SimLog: Dynomation-6 displays more data and feedback in the SimLog than our other simulations (the SimLog file is generated after each simulation run and can be displayed by selecting Show Sim Log from the Simulation menu available at the top of the main program screen). In Dynomation-6, we realize that all information about issues that may occur during a simulation run will help the professional user track down problems or correct errors in data entry, so all sim-generated messages and data are displayed by default.

(54) Dual FE and WA Simulation Model: Dynomation-6 includes both the DynoSim6 Filling-And-Emptying mathematical model and the Full Wave-Action, Method-Of-Characteristics engine model. You can instantly switch between these simulations with just a mouse click. This provides the engine researcher/developer with optimum flexibility and modeling feedback. For example, instead of entering all the pipe and runner specifications into the Intake and Exhaust categories for the WA model, you can switch to the FE and the sim will estimate these values for you! Then, jump back to the WA model to delve deeper into passage lengths and pressure tuning. This feature also allows you to load an run any DynoSim6 engine file.
