摘要： A reciprocating engine has a piston which reciprocates in a cylinder due to explosion pressure produced in a combustion chamber (124) formed in the cylinder (110). The reciprocating engine includes: a liquid fuel supply unit (148) that supplies a liquid fuel to the combustion chamber; and a gas supply unit (a fuel gas supply unit (150) and an EGR supply unit (152)) that supplies, into the cylinder, fuel gas and EGR gas as exhaust gas which is produced from combustion in the combustion chamber and is discharged from the combustion chamber.

摘要： 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.

摘要： A uniflow scavenging two-cycle engine includes a scavenge port which is provided on one end side in a stroke direction of a piston in a cylinder (110), and sucks an active gas; and a plurality of injection units (126g and 126f) which inject a fuel gas into the active gas sucked into the scavenge port and are provided on an inner circumferential surface of the scavenge port or on the outside of the cylinder compared to the inner circumferential surface, and have different positions of the piston in the stroke direction. Further, the plurality of injection units are divided into at least two sets of injection unit groups include a first injection unit group (160) and a second injection unit group (162), the first injection unit group being a set of one or a plurality of injection units located on the other end side in the stroke direction, and the second injection unit group being a set of one or a plurality of injection units located on one end side in the stroke direction, and the injection stop of the fuel gas is later in the injection unit of the first injection unit group than in the injection unit of the second injection unit group. With the configuration, it is possible to provide a scavenging two-cycle engine which suppresses blow-by of the fuel gas, while uniformly diffusing the fuel gas.
