Title:
Uniflow Scavenging type 2-cycle engine
Document Type and Number:
Japanese Patent JP6065974
Kind Code:
B2
Abstract:
A uniflow scavenging 2-cycle engine includes a cylinder (110) inside in which a combustion chamber is formed; a piston which slides within the cylinder; a scavenge port (122) which is provided on one end side in a stroke direction of the piston in the cylinder to suck an active gas into the combustion chamber in accordance with the sliding movement of the piston; and an injection unit (126) which injects a fuel gas into the active gas suctioned to the scavenge port and is provided on an inner circumferential surface of the scavenge port or on the outside of the cylinder rather than the inner circumferential surface. Further, the amount of the fuel gas injected by the injection unit on the other end side in the stroke direction is larger than the amount of fuel gas injected by the injection unit on one end side in the stroke direction. With such a configuration, it is possible to provide a uniflow scavenging 2-cycle engine which can suppress the flame-out or abnormal combustion by equalizing the concentration of the fuel gas that reaches the combustion chamber from the scavenge port.
