Title:
CONTROL DEVICE OF COMPRESSION AUTOIGNITION ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/096586
Kind Code:
A1
Abstract:
This control device of a compression autoignition engine is provided with an engine (1), a supercharging system (49), an external EGR system (55B), a spark plug (25), a controller (ECU10) and sensors (SW1-SW16). In the case that the operation state of the engine is within a prescribed operation region, the spark plug ignites the air-fuel mixture at a prescribed timing such that, after combustion through flame propagation, the air-fuel mixture combusts through autoignition. The external EGR system increases the burnt gas introduced into the combustion chamber more in a first region, which has a relatively high engine load, than in a second region, which has a relatively low engine load, and the supercharging system increases the boost pressure more in the first region than in the second region.
