Engine management<br />

Electronic accelerator<br />

The electronic accelerator is a basic requirement<br />

for direct petrol injection. It helps to adjust the<br />

throttle valve regardless of accelerator pedal<br />

position. It is opened wider in stratified charge<br />

mode and homogeneous lean charge mode.<br />

This has the advantage of almost throttle-free<br />

engine operation. The engine is able to draw in<br />

air against less resistance, reducing fuel<br />

consumption.<br />
