Direct fuel injection control system for internal combustion engine has timing controlled to promote stratified charge at low speed and homogenous mixture at high speed

摘要

The control system performs a first control step (S10) to determine the running speed (U) of the engine. The second step (S11) compares the engine speed with a threshold value (SW). If U greater than SW (Ja), then a third step (S12) is performed, to calculate the injection path for the next cylinder to receive a fuel injection. If U less than SW (Nein), then a fourth step (S13) is performed, to calculate the injection paths for all cylinders. The third or fourth step runs a fifth step (S14) which triggers the next fuel injection.
