Title:
GAS ENGINE WITH TURBOCHARGER, AND COMBUSTION METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2020/179141
Kind Code:
A1
Abstract:
This pilot ignition type gas engine with a turbocharger repeats a combustion cycle comprising an intake stroke for sucking a lean air-fuel mixture including gaseous fuel and air into a combustion chamber, a compression stroke for compressing the lean air-fuel mixture, an expansion stroke in which combustion gas generated through combustion of the lean air-fuel mixture expands, and an exhaust stroke for exhausting the combustion gas from the combustion chamber, wherein first injection for injecting liquid fuel into the combustion chamber is performed at a first timing in the compression stroke, and second injection for injecting liquid fuel into the combustion chamber begins at a second timing in the expansion stroke, in the second half of a combustion period in which the lean air-fuel mixture in the combustion chamber burns by propagation of a flame generated by the first injection.
