Abstract

PURPOSE: To reduce a constructive weight and a ignition noise by providing an auxiliary chamber valve which closes a nozzle hole communicating both main and auxiliary combustion chambers, and an auxiliary combustion chamber piston which compresses an air in the auxiliary combustion chamber.
CONSTITUTION: A moment before a compression stroke is completed in a main combustion chamber 1, an auxiliary combustion chamber valve 20 closes a nozzle hole 22 which communicates the main combustion chamber 1 with an auxiliary combustion chamber 21. The auxiliary combustion chamber valve 20 is inserted so as to freely reciprocate inside a valve guide cylinder 23 which extends through a cylinder head 3 and opens to the main combustion chamber 1. Is provided an auxiliary combustion chamber piston 24 which narrows the inside space of the auxiliary combustion chamber 24 to compress a sucked air after the nozzle hole 22 is closed by the auxiliary combustion chamber valve 20. Thereby, only a mixture in the auxiliary combustion chamber 21 can be ignited at a higher compression ratio so that a weight of an engine may be relatively low and an ignition noise may be reduced.
