摘要： A two stroke engine equipped with a mechanically driven supercharger in the intake passage downstream of throttle valve. A bypass air passage bypassing the supercharger is provided, and a bypass air control valve is arranged in the bypass air passage. When the engine is idling, the bypass air control valve is controlled so that the level of vacuum in the intake passage between the throttle valve and the supercharger is maintained at a constant value.

摘要： A two-stroke engine including a pair of intake valves. A masking wall is provided for each intake valve to mask the valve opening between the valve seat and the peripheral portion of the intake valve, which is located on the exhaust valve side, for the entire time for which the intake valve is open. The exhaust valves open earlier than the intake valves, and the exhaust valves and the intake valves are closed at substantially the same time.

摘要： A two-stroke engine comprising a spark plug arranged at the center of the inner wall of the cylinder head, and a fuel injector arranged on the periphery of the inner wall of the cylinder head. A depression extending from the point beneath the spark plug to the point beneath the tip portion of the fuel injector is formed on the top face of the piston. When the engine is operating under a light load, fuel is injected by the fuel injector only once toward the depression, and conversely, when the engine is operating under an intermediate load, fuel is injected twice. Namely, a first injection is carried out when the piston is at a lower position, and a second injection is carried out when the piston is at a higher position, to thus direct fuel toward the depression.

摘要： An internal combustion engine comprising a spark plug arranged at the center of the inner wall of the cylinder head, and a fuel injector arranged on the periphery of the inner wall of the cylinder head. A depression is formed on the top face of the piston. This depression is defined by a flat bottom wall and a pair of extended straight side walls which diverge toward the fuel injector side. Fuel is obliquely injected on the flat bottom wall of the depression from the fuel injector.

摘要： An internal combustion engine having an air blast valve which injects fuel together with pressurized air in the form of a conical shaped spray of fuel. A depression is formed on the top face of the piston, and the conical shaped spray of fuel is injected from the air blast valve toward the depression. The longitudinal width of the depression in the moving direction of the spray of fuel is larger than the transverse width of the depression in the direction perpendicular to the moving direction of the spray of fuel, and the opposing side walls of the depression, which define the transverse width of the depression, are positioned slightly outward from the side face of the conical shaped spray of fuel.

摘要： A control device for an internal combustion engine comprises a fuel injector provided for each cylinder, an ignition plug starting ignition in each cylinder simultaneously with a start of the engine cranking, and a detection unit for detecting combustion in each cylinder when the engine is started which determines that the fuel injector of a cylinder in which ignition is carried out before fuel injection has a fuel leak when combustion is detected in the cylinder.
