摘要： Under a partial load, a pumping loss is reduced by a stratified combustion to enhance a fuel consumption, and during the maximum output operation, the output is increased by a premixture combustion, and the output of an engine is controlled, thereby enhancing the drivability. Under the partial load, an ignition source is provided in the vicinity of a fuel injection valve, and after the fuel is injected, the mixture is ignited, and a resulting flame is caused by a spray of the fuel to spread into a cylinder, thereby effecting a stratified combustion. When the load increases, so that soot and so on are produced in the stratified combustion, the fuel injection is effected a plurality of times in a divided manner, and a premixture is produced within the cylinder by the front-half injection, and a flame, produced by the latter-half injection, is injected into the cylinder to burn this premixture.

摘要： A fuel injection system injects fuel to an internal combustion engine having a plurality of cylinders by means of a single fuel injector. For a four cylinder engine in which the suction stroke is repeated in the order of first, third, fourth and second cylinders, the single fuel injector responds to a control signal from a control system to initiate a single-shot injection upon the suction strokes of the first and the fourth cylinders. The fuel injection initiating timing as well as the injecting duration are arithmetically determined by a CPU a and ROM of the control system on the basis of the signals representative of operating conditions of the engine available from a hot-wire sensor, a crank angle detector, a temperature sensor, an O.sub.2 -sensor and supplied to the single fuel injector. The cylinders to which the fuel is to be injected are changed over from the first and fourth cylinders to the second and the third cylinders by the CPU in response to the signal output from the O.sub.2 -sensor.

摘要： In order to prevent a catalyst for an internal combustion engine from decreasing efficiency by deterioration after long time use of the catalyst, the decreased efficiency of the catalyst is determined, and the internal engine is controlled based on results of the determination so as to maintain high efficiency of the catalyst. The catalyst is installed in an exhaust pipe of the engine. Sensors for detecting conditions of exhaust gas both at upstream side and downstream side of the catalyst are provided, respectively. As for the sensor, for example, an oxygen sensor of which output varies stepwise at λ=1, or a sensor of which output varies in proportion to air-fuel ratio can be used. Detected values of the sensors are taken into a control unit, eliminating efficiency and deteriorating degree of the catalyst are estimated by comparison of the detected values, and the engine is controlled so that the eliminating efficiency becomes maximum. In accordance with the present invention, a preferable exhaust gas cleaning characteristics of the catalyst can be maintained because the decreased efficiency of the catalyst is determined exactly and the engine is controlled so as to prevent the catalyst from decreasing efficiency.

摘要： Swirl strength is formed to be 1-3.5, and the fuel mist speed of the fuel to be injected into a combustion chamber is formed to be 5-37 m/s or 5-25 m/s, whereby the air fuel ratio (A/F) is used as the lean limitation. Further, a control apparatus determines a lean combustion region according to the swirl strength and the fuel mist speed. By paying using the injection speed of the fuel, the rich air-fuel mixture and the lean air-fuel mixture are stratified by the combination of the swirl shape (the swirl strength) and the fuel mist speed.

摘要： An engine exhaust gas recirculation system has an intake passage (2) connected to feed an air/fuel mixture to an internal combustion engine and an exhaust passage (1) connected to discharge an exhaust gas from the internal combustion engine. An exhaust gas recirculation passage (3) is provided for feeding a portion of the exhaust gas of the exhaust passage into a cylinder of the engine such that a laminar distribution is produced in the cylinder formed by air/fuel mixture adjacent to the ignition plug and the recirculated exhaust gas distributed about the air/fuel mixture. The exhaust gas recirculation passage may open in the vicinity of an intake valve of the engine or open into the cylinder above the bottom dead center of the piston. The flow of recirculated exhaust gas may be controlled by pressure, for example by the inlet and exhaust valves of the engine and/or by a pressure control valve (31, 34). Alternatively, the exhaust gas recirculation may be controlled in a multicylinder engine by a distributor (20) which may be controlled by an engine "roughness" control signal. The EGR may be computed from outputs of an air flow sensor (7) and an intake manifold pressure sensor (50).

摘要： In the fuel cylinder injection engine with the supercharging machine, the ignitability deteriorates because the density of the fuel at the spray center becomes excessive due to the shrinkage of the fuel spray under the supercharging. As a result, the density of the smoke and the hydrocarbon exhaust rate increase. The mixture of the fuel and the air under the supercharging is promoted by the control by TCV installed in the suction port which is a divided spray and air flow generation mechanism and the valve timing control of the suction and exhaust valve, etc.
