Title:
PREMIXED COMPRESSION IGNITION TYPE ENGINE WITH SUPERCHARGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/039554
Kind Code:
A1
Abstract:
When a geometric compression ratio of an engine body (2) is set to 13 or more and the engine body is operating in a preset high load region, an effective compression ratio of the engine body is set to 12 or more and within a range having a difference of 2 or less relative to the geometric compression ratio, gas to be introduced into a combustion chamber (17) is supercharged by a supercharging system (49), fuel is injected in at least a compression stroke by an injector (6), and after fuel injection is complete and before compression top dead center, the air-fuel mixture in the combustion chamber is ignited by an ignition plug (25), thereby causing non-combusted air-fuel mixture to combust in the engine body by means of compression ignition after the air-fuel mixture has been caused to combust by flame propagation.
