    摘要： Enhanced combustibility by increasing the difference in intake gas velocity between a low flow velocity region and first and second high flow velocity regions in an intake port. An intake port of an internal combustion engine has an intake flow control port portion provided with first and second projecting portions. In the passage cross section of the intake flow control port portion, there are provided a low flow velocity region, and first and second high flow velocity regions formed on either side of and across the low flow velocity region and the first and second projecting portions wherein the maximum flow velocity of intake gas is comparatively larger than that in the low flow velocity region. The intake gas reaches intake ports with a flow velocity distribution having the relationship of the magnitudes of flow velocities in the low flow velocity region and first and second high flow velocity regions.

    摘要： An internal combustion engine having a cylinder head body with a pentroof-shaped combustion chamber comprises a piston including a piston cavity and a caldera-shaped protrusion provided around the piston cavity, a fuel injector for injecting fuel downward to the piston cavity and a spark plug disposed obliquely in proximity to an intake valve. The piston cavity is provided on the top surface of the piston being offset on the spark plug side. Further, the caldera-shaped protrusion is slanted towards the spark plug side. Therefore, injected fuel collides against a down-slope of the piston cavity and is diffused partly towards the spark plug and partly towards the cylinder head. As a result, a locally rich air-fuel mixture is formed around the spark plug so as to enable stratified charge combustion.

    摘要： An internal combustion engine comprising a piston having a top face with a depression formed therein, and a first fuel injector and a second fuel injector arranged on the inner wall of the cylinder head. Fuel is injected from the first fuel injector when the position of the piston is high, and fuel is injected from the second fuel injector when the position of the piston is low. The axes of fuel injection of both fuel injectors are determined such that fuel injected from the fuel injectors is directed to the central portion of the depression.

    摘要： An internal combustion engine is comprised of a gas injecting device injecting gas into the combustion chamber of the internal combustion engine, and a gas injection control device controlling the gas injecting device, wherein the gas injection control device provides control such that the gas is injected toward the combustion chamber for a period of time after flame extinguishing timing and before exhaust valve closing timing. Therefore, the internal combustion engine is capable of reliably combusting HC, CO, smoke, and so forth remained in a combustion chamber due to a quenching phenomenon or the like.

    摘要： The invention relates to a spark ignited internal combustion engine with at least one cylinder that accommodates a reciprocating piston, with a cylinder head that receives at least one ignition device per cylinder and in which are formed one exhaust and two intake manifolds, said exhaust manifold communicating with a combustion chamber by way of one exhaust port and said intake manifolds communicating therewith by way of intake ports, said exhaust port being controlled via an exhaust valve and said intake ports via intake valves, said exhaust port on the one hand and said intake ports on the other hand being arranged to different sides of an elevated plane of the engine that passes through the axis of the cylinder and through the axis of the crankshaft, said intake manifolds being at least in sections arranged substantially in the direction of the cylinder's axis and being formed in such a manner that a reverse tumble flow is initiated in the combustion chamber, said flow being oriented from the intake ports toward the piston and from there toward the exhaust port. In order to reduce the flow losses in the combustion chamber in the easiest possible manner, there is provided that at least one ignition device be arranged in the cylinder head bottom to the side thereof in the region of the cylinder wall.
