Title:
CONTROL DEVICE FOR COMPRESSION IGNITION TYPE ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/212015
Kind Code:
A1
Abstract:
A control device according to the present invention is applied to a compression ignition type engine that enables partial compression ignition combustion in which SI combustion of part of an air-fuel mixture is caused by spark ignition and CI combustion of the rest of the air-fuel mixture is caused by self-ignition. This control device is provided with: an ignition control unit that causes a spark plug to execute, while partial compression ignition combustion is executed, a main ignition for starting SI combustion by generating a spark during the late stage of a compression stroke or the initial stage of an expansion stroke and a preceding ignition for generating a spark at a timing before the main ignition; and an injection control unit that causes an injector to inject fuel at a timing such that there is fuel in a cylinder at a point of time before the preceding ignition, while the partial compression ignition combustion is executed likewise. The energy of the preceding ignition is set lower when a swirl flow is weak as compared to when the flow is strong.
