Fuel injection mechanism for an internal combustion engine has a fuel pressure chamber and a fuel injection device linked to the chamber via a pipe to carry out two injections per cycle.

摘要

If a fuel injection device (FID) (1) carries out two injections per cycle with a high-pressure pump (4), speed of advance in fuel pressure is calculated between first and second injections and a fuel amount injected during the second injection is adjusted by applying this speed. Each FID and fuel pressure chamber (2) link via a pipe (3).
