Document Type and Number:
Japanese Patent JP6019941
Kind Code:
B2
Abstract:
A uniflow-scavenging-type two-cycle engine (100) of the present invention includes: a cylinder (110); a piston (112) that slides in the cylinder; an exhaust port (116) that is provided at a first end of the cylinder; an exhaust valve (120) that opens and closes the exhaust port; a scavenging port (122) that is provided in an inner circumferential surface of a second end of the cylinder in the stroke direction of the piston and draws in an active gas into the combustion chamber (140) in accordance with a sliding movement of the piston; and a plurality of fuel injection valves (128) that inject a fuel gas to the active gas, which has been drawn in from the scavenging port to the combustion chamber, to thereby generate a premixed gas. The fuel injection valves at least include: a first fuel injection valve that injects a fuel gas along a swirling flow of the active gas drawn in into the cylinder; and a second fuel injection valve that injects a fuel gas toward a direction closer to a central axis of the cylinder than the direction of the fuel gas from the first fuel injection valve.
