摘要： A removal tool configured for removing an insertable engine component from an engine assembly. In the removal tool may include a coupling device, a drive member, and a lifting member attached to a main shaft. The coupling device is mounted onto a retainer securing an engine component, and the lifting member is positioned against the underside of a flange of the engine component. A rotational force applied against the drive member is transferred to the coupling device and causes the retainer to be unscrewed. As the retainer is unscrewed, this causes a lifting force from the retainer pushing against the coupling device, which causes the lifting member to be pushed upward, and further causing the engine component to be pushed upward and away from the engine assembly. This facilitates removal of the engine component concurrently with the removal of the retainer (e.g., in a single operation).

摘要： The invention relates to an engine having prechamber ignition, in particular a gas engine, that comprises a main combustion space in a cylinder of the engine for combusting an air-fuel mixture and a prechamber having an ignition device arranged therein and a fuel injector arranged therein, wherein the prechamber has at least one transfer port that fluidically connects the prechamber to the main combustion space. The engine is characterized in that the fuel injector arranged in the prechamber is the only fuel injector via which fuel can be introduced into the associated main combustion space.

摘要： An object of the present invention is to provide a fuel injection system capable of suppressing an occurrence of distortion in an injector during assembly of components. A fuel injection system (3) includes: a bracket (5) which is fixed to a cylinder head (21) of an engine (2); a fuel accumulator (6) which is supported by and fixed to the bracket (5) and which accumulates pressure of fuel supplied from a fuel pump; and an injector (7) which is directly connected to the fuel accumulator (6) and mounted to the cylinder head (21) and which injects the fuel, supplied from the fuel accumulator (6), into a combustion chamber. At least one of the fuel accumulator (6) and the bracket (5) has guide members (64, 513) which guide the injector (7) to a mount position on the cylinder head (21).

摘要： An improved injector cup may be used in diesel engines that fits more securely into the engine's cylinder heads to better prevent engine coolant from leaking into the fuel and/or fuel leaking into the coolant. An improved injector cup may be designed to accommodate specific engine types and sizes in order to prevent engine coolant from leaking into the fuel and/or fuel leaking into the coolant.

摘要： An opposed-piston engine includes: a cylinder; a one-side piston disposed inside the cylinder on one side in an axial direction; and an other-side piston disposed inside the cylinder on another side in the axial direction. Atop surface of the one-side piston has a one-side cavity recessed in a central portion. A top surface of the other-side piston has an other-side cavity recessed in a central portion. An outer peripheral edge of the one-side cavity is at least 0.1D1 away from an outer peripheral edge of the top surface of the one-side piston over the entire circumference, where D1 is a diameter of the top surface of the one-side piston. An outer peripheral edge of the other-side cavity is at least 0.1D2 away from an outer peripheral edge of the top surface of the other-side piston over the entire circumference, where D2 is a diameter of the top surface of the other-side piston.
