摘要： An injection control unit of a fuel is provided, which prevents generation of a nozzle deposit of a fuel injector. In a control unit of a fuel injector capable of controlling a lift height that is a distance between a valve body and a valve seat, after start of fuel injection and before end of the fuel injection, after the lift height is controlled to a first height, a period in which the lift height is controlled to a second height which is lower than the first height is provided for a predetermined period. According to such a configuration, when the lift height of the valve body is lowered to the second height after the fuel is injected at the first height, a fuel velocity in the vicinity of an inner wall of an injection port is increased due to an inertial force of the fuel and reduction in an opening area. By a fuel flow at a high velocity, a contamination substance adhering to a wall surface is washed away.

摘要： A combustion chamber is formed using a flat piston having a low cooling loss and therein a forward tumble is generated. A fuel spray is formed by a provision of a splitter which is provided to make off-set from a center of an injection port at a tip end of a tumble atomization system fuel injector. The fuel spray is divided into a fuel spray having a strong penetration force and a fuel spray having a small penetration force. The fuel spray having the strong penetration force is injected in a vicinity of an ignition plug. Accordingly, a fuel adhesion to the piston can be reduced and further a reduction of a discharge HC and a fuel consumption can be improved.

摘要： With a cylinder direct injection engine in which fuel is injected directly into combustion chambers and air-fuel mixture is guided by an air flow, it is difficult to secure combustion stability under low engine speed and low load conditions such as during idling. Furthermore, there are needs for improvement of emission characteristics and fuel economy in other operation modes as well. An engine according to the invention injects fuel while dividing the same in plural parts during a compression stroke. The first injection forms a lean air-fuel mixture around an ignition plug, and the second injection makes a flammable air-fuel mixture reach an area around the ignition plug. This ensures efficient stratified combustion and allows improvement in emission and fuel economy performance.

摘要： A fuel injector employed in a direct injection engine comprising a spark plug arranged on the top of a combustion chamber, a fuel injector located on said combustion chamber and an intake air control means installed on an intake manifold. A forward tumble air flow is formed in the combustion chamber by the intake air control means, and the fuel injector is available in two types; an annular (conical) spray type characterized by uniform density and a spray type characterized by high/low density. In the case of latter type, arrangement is made to ensure that the denser portion is placed face-to-face with the spark plug. Spray fuel rises along the wall surface of the combustion chamber on the intake side, and is carried to the spark plug by forward tumble air flow (called “tumble guide”) moving from the fuel injector to the spark plug. This allows stratified charge combustion to be performed in the operation range from low to high speed ranges, with the result that discharge of gas containing hazardous gas component such as THC is reduced and fuel economy is improved.
