  Proven Technology For Two-Stroke Engines!

Two-Stroke Sim
Used By Pros And Engine

Note: This is a DOS-based application.
It now runs in all versions of Windows (98/XP/7/8/10/11) using DOSBOX.

   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.

   With 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.
