The piston crown (11.1) and the cylinder cover (2.1) are substantially roof-shaped in vertical section. A fuel injection nozzle (8) opens into the cylinder (1) near the inlet region of the intake ports (3) between the intake valves (6), wherein, measured in relation to the cylinder axis, (5) the angle of the jet axis (9) of the fuel injection nozzle (8) is greater than the angle of the intake ports (3). An ignition device (14) is arranged in the cylinder cover(2.1) close to the cylinder axis (5). A through-shaped recess (12) is provided in the piston crown (11.1) bounded by a through base (12.1) and side walls (16) and inter-sects the roof ridge (11.2) on the piston crown. The trough base (12.1) being inclined towards the fuel injection nozzle (8) and ending in a wall zone (12.2) extending steeply upwards on its side facing the fuel injection nozzle (8), wherein the transition regio (15) between the through base (12.1) and the side walls (16) has a substantially barrel-shaped contour in plan view.

The invention provides a method for expanding and optimizing compression ignition operation range of an internal combustion engine applying variable valves. The internal combustion engine comprises intake valves, exhaust valves and electromagnetic full-variable valve devices, the intake valves and the exhaust valves are respectively provided with the electromagnetic full-variable valve devices forcontrolling the opening lift size and the opening phase angle of the intake valves and the exhaust valves; the electromagnetic full-variable valve devices drive the exhaust valves to open during an exhaust stroke period, so that exhaust gas starts to be discharged out of a cylinder; at some point of the exhaust stroke, the intake valves are driven to open, so that part of exhaust gas flows back into an intake manifold; and the lift for controlling the opening of the intake valves by the electromagnetic full-variable valve devices is decreased as the engine load is increased. According to themethod for expanding and optimizing compression ignition operation range of the internal combustion engine applying the variable valves, the small EGR rate can be adopted at high load to reduce severecombustion or knocking in the homogeneous compression ignition process, and the larger EGR rate can be adopted at low load to reduce incomplete combustion or misfire in the homogeneous compression ignition process, so that the homogeneous compression ignition operates in a larger operating range.

The gas engine of the present invention has a pilot oil fuel valve, a pilot oil pump, and first and second pipes connected to a pilot oil main pipe, for each of a plurality of combustion chambers. An operating pilot oil tank and an ignition stimulant-added pilot oil tank are connected via a switching valve to a third pipe, connected to an end of the pilot oil main pipe. Before operating stops, the pilot oil is discharged by opening an exhaust valve, and thereafter, the switching valve is switched and pilot oil which the ignition stimulant has been added to is supplied into the pipe. Consequently, the pilot oil downstream from the main pipe is replaced with the pilot oil which the ignition stimulant has been added to. Therefore, at the time of the next activation, pilot oil which the ignition stimulant has been added to is sprayed from the fuel valve, and, as a result, misfire at the time of activation is reduced, and a highly reliable engine is obtained.

A method for operating an engine in response to a waste gate position is presented. In one example, the method adjusts an actuator to reduce the possibility of misfire in an engine cylinder in response to waste gate position. In this way, it may be possible to adjust engine operation for varying engine operating conditions.

The invention discloses a control system and a control method of an oil / gas dual-fuel engine in electronic control oil supply. The control system comprises a high-pressure common-rail injection system, a fuel gas injection system and an oil / gas dual-fuel electronic control system, wherein the oil / gas dual-fuel electronic control system comprises a sensor part, an actuator, a dual-fuel ECU (Electronic Control Unit) and a fuel oil ECU, the oil / gas dual-fuel electronic control system controls the diesel oil amount through an oil injector, the fuel gas amount through a fuel gas control injection nozzle and the air inlet amount through an electronic throttling valve body, and an air-fuel ratio when the oil / gas dual-fuel engine works can be detected and controlled in a closed loop feedback way through a wide-domain oxygen sensor.

The invention relates to systems and methods for diagnosing air and fuel offsets in a prechamber. Methods and systems are provided for a vehicle engine having a pre-chamber ignition system. In one example, a method may include adjusting one or more of an air injection amount and a fuel injection amount to a pre-chamber of an engine based on an air injection offset and a fuel injection offset learned while discontinuing fueling to cylinders of the engine and reducing air flow through the engine. In this way, air and fuel may be more accurately provided to the pre-chamber, thereby decreasing an occurrence of pre-chamber misfire.
