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 engines 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.
