TWO-CYCLE INTERNAL COMBUSTION ENGINE AND ENGINE WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/177010
Kind Code:
A1
Abstract:
This two-cycle internal combustion engine comprises: a fuel injection valve 25 that supplies fuel into a crank chamber 8; an intake passage 17 that intakes only air, said intake being due to the negative pressure when a piston 4 operates; and a scavenge passage 18 that communicates the crank chamber 8 and a combustion chamber 6. The air that passes through the intake passage 17 is introduced into the scavenge passage 18, and when the intake is completed, the air retained in the scavenge passage 18 participates in the scavenging.
