摘要： The engine system (100) includes: a variable compression device (6, 7 and 8) including a fluid chamber (R3) in which a piston rod (6) connected to a piston (4) is moved in a direction to increase a compression ratio by a pressurized working fluid being supplied thereto; a detection device (400) that outputs a signal including positional information of the piston; and a position acquisition device (300) that acquires a position of the piston based on the signal.

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： In a diesel engine 1 with fuel injection valves 6a and 6b for injecting fuel 5a, 5b into a combustion chamber 4, respectively, the valves 6a and 6b are arranged such that they are opposed to each other horizontally and diametrically of the combustion chamber 4 in a plan view and are out of alignment in height to each other axially of a cylinder 2. With the valves 6a and 6b being positioned close to and away from the cylinder head 7, respectively, an upper surface of the piston 3 has a rising gradient extending from its side adjacent to the valve 6b toward its side adjacent to the valve 6a up to diametrically halfway of the piston 3.

摘要： A variable compression device includes: a piston rod (6); and a fluid chamber (R3) in which, when a pressurized working fluid is supplied thereinto, the piston rod (6) is caused to move in a direction in which a compression ratio increases. A grooved flow path (R6) is formed in a bottom surface of the fluid chamber (R3) or a contact surface of the piston rod (6) in contact with the bottom surface of the fluid chamber (R3).

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.
