Engine Model Two-Stroke
EngMod2T: A multi-cylinder two-stroke engine simulator.
The software does complete cycle simulation of the whole internal combustion process including the gasdynamics in the pipes/ducts, ports and plenums (air boxes, boost bottles, exhaust boxes etc.) using the GPB-method for pipe flows.
It has successfully been used to simulate a range of engines from small glow plug engines to kart and motorcycle competition engines, to Formula 1 V6 powerboat engines, to boxer layout micro light and UAV engines, and also opposed piston engines and Uniflow engines with poppet exhaust valve etc.
The EngMod2T suite consists of five main programs:
The are also some support software:
MotaToDat2T - software that converts a Mota model to a Dat2T model.
Movie2T - software that shows the animated left and right moving pressures and the superposition pressures for a selected number of exhaust systems.

Typical power Curve (in kW)
