Dynomation-5.16Four-Stroke Simulation
  Proven Four-Stroke Technology Speeds Engine
Runs Under All Versions Of Windows: XP to Windows 10

Engine Simulation

Used By Pros And Engine Enthusiasts

   Dynomation-5 lets you peer inside a running four-stroke engine! It reveals–otherwise invisible–pressure waves and mass flow in cylinders and engine passages. Dynomation not only accurately displays how much power an engine will produce, but it also shows you why it makes that power and where you should put your efforts to optimize performance!

  The latest release (version 5.16) adds several GTX Turbo maps, E85 modeling, enhanced combustion and ignition modeling and more. Recent previous updates added improved integration between the FE and WA models, improved camshaft and rocker-arm modeling, improved tables and charts, new Pressure-Volume and Pressure-Crank-Angle graphs, Crank-Degree data tables, comprehensive support for metric and US measurement systems, output data to spreadsheets and much more! Fully compatible with Windows XP, Vista, 7, 8 and Windows10 (32- and 64-bit).

  Proven Technology For Two-Stroke Engines!

Two-Stroke Sim

Used By Pros And Engine Enthusiasts

Note: This simulation requires Windows98 or WindowsXP (32-bit).
 DynomationTwoStroke is a full-cycle simulation, that calculates the complete fluid-dynamic, thermodynamic, wave-dynamic, and frictional conditions that exist inside the cylinders and runners throughout the entire 360 degrees of the two-cycle process. Model engines with Piston-Port, Reed, or Rotary valving. Design Expansion Chambers, watch pressure-waves "Live" as they move in exhaust ducting. Perform quick "what if" testing to zero in on the best combinations for any application.

 Wtih DynomationTwoStroke, you'll build and test two-stroke engines in no time! You can depend on this package to produce solid, accurate predictions of engine performance characteristics.No other two-stroke engine simulation comes close to DynomationTwoStroke for simulation capability, accuracy, and ease of use.
