Abstract: According to the present invention, each of the cylinders of an engine is provided with a swirl port, which generates a swirl in the cylinder, and a conventional straight port. A swirl control valve is disposed in an inlet air passage connected to the straight port for blocking the flow of inlet air through the straight port. A fuel injection port is disposed in each of the swirl port and the straight port. The fuel injection port in the straight port is disposed at the position adjacent to the upper edge of the valve seat of the straight port inlet valve. When the swirl control valve blocks the inlet air passage leading to the straight port, fuel is injected from the fuel injection port of the straight port in the latter half of the intake stroke of the piston. The direction of fuel injection from the fuel injection port in the straight port is determined in such a manner that fuel is injected in the direction between the center axis of the cylinder and the center axis of the stem of the valve element of the inlet valve toward the opposite wall of the cylinder head or the upper part of the opposite wall of the cylinder.

Abstract: There is provided a fuel injection valve in which nozzle holes are formed on a metering plate and fuel flowing on a face of the metering plate on the upstream side is injected outside of a face of the metering plate on the downstream side through the nozzle holes. The fuel injection valve includes a vortex flow generator means for changing a flow of fuel passing in each nozzle hole into a vortex flow, wherein the vortex flow generator means is provided on the upstream side of the metering plate. The vortex flow means is a vortex flow generator groove provided on an upper face of the metering plate and connected with a wall face of an entrance of the nozzle hole, and a main stream of fuel flowing in the groove is directed to a position shifted from the center of the nozzle hole. Alternatively, the vortex flow means is a protrusion formed on an upper face of the metering plate. A flow of fuel is changed into a vortex flow in the nozzle hole and injected from the nozzle hole. Therefore, fuel can be excellently atomized and diffused as a megaphone-shape without being formed into a liquid column spray.

Abstract: A fuel injector (6) and spark plug (7) are arranged in a combustion chamber (5) of an internal combustion engine. By forming by stratification a self-ignitable preliminary air-fuel mixture in the combustion chamber (5), a spatial distribution is given to the density of the preliminary air-fuel mixture in the combustion chamber (5). Part of the preliminary air-fuel mixture formed in the combustion chamber (5) is ignited by the spark plug (7) to cause combustion by flame propagation, then the remaining preliminary air-fuel mixture is successively made to self-ignite and burn with a time lag. The ignition timing is set so that the ratio of the preliminary air-fuel mixture made to burn by self-ignition becomes more than a predetermined lower limit and less than a knocking generation limit.
