Title: Determining required fuel injection quantity for two-stroke engine involves integrating pressure variation in selected window to derive load pressure; deriving start, duration of injection
Inventor: HAUKE WOLFGANG
IPC: F02B75/02
Filed: 1998-10-08
Abstract: The method involves determining the required fuel injection quantity for a two-stroke internal combustion engine from the air mass flow which the engine sucks in via an induction path with an input air filter and an output choke flap.
