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： The engine disclosed features an engine cylinder provided with an air intake valve, an injector having a fuel injection port which is directed towards an interior of the engine cylinder, and a control unit which is connected to the air intake valve and to the injector, the control unit effecting changes in the air intake amount by controlling the degree of opening of the air intake valve, and, also, controls the air/fuel ratio by changing the amount of fuel supplied by the injector. The engine also has an exhaust valve in the engine cylinder such that the control unit controls the intake valve and the exhaust valve so that an opening period of the intake valve is overlapped with an opening period of the exhaust valve at least when the opening period of the intake valve is maximum. The period of the overlap is longer when a relatively large amount of air is required than when a relatively small amount of air is required. According to such a scheme, the amount of the air can be changed by the lift of the intake valve. By changing the lift, the overlap with an exhaust valve is also changed. During the high-output or power operation, the period of overlap between the exhaust valve and the intake valve is made longer. When engine torque decreases to a level lower than the target engine torque, the air amount is adjusted by the cam or the throttle valve.

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 intake and exhaust system for use with internal combustion engines that uses two intake valves and one exhaust valve for each engine cylinder. The three valves are preferably circular and spaced around the cylinder centerline in said cylinder head. One or more spark plugs (or other suitable ignition devices) are provided in the head on the cylinder centerline and/or between pairs of adjacent valves. For best results, the two intake valves have substantially equal diameters. Preferably, the ratio of exhaust valve diameter to intake valve diameter is from about 0.95:1 to 1:1.2. The head typically has three substantially hemispheric depressions each housing one of said valves. Squish areas are preferably provided around said combustion chamber periphery. The piston surface may be at least partially planar and may have an angled or radiused periphery or may have a central recess corresponding generally to the valve region. This invention provides a fast and uniform lean burn, permits use of a high compression ratio and lower octane unleaded gasoline and provides improved thermal efficiency. Other fuels and other fuel ignition systems also benefit, such as diesel engines.

摘要： A system for introducing fuel into the combustion chamber of an internal combustion engine which includes at least one piston reciprocating in a cylinder with a cylinder head closing the top of the cylinder forming a combustion chamber between piston and head. At least one intake valve and one exhaust valve are provided in the cylinder head. One or more fuel injectors communicate through the sidewall of each of the engine cylinders for injecting fuel during the piston intake stroke while the top of the piston is below the injection site. The fuel injector may be any suitable injector, typically of a low pressure type. The fuel injector is oriented to direct a spray of fuel droplets in the direction of the cylinder head and/or the closed exhaust valve to speed droplet evaporation and cool the exhaust valve. Engines using this system also have increased tolerance of low octane fuel and improved emission characteristics.

摘要： A direct-injection type compression-ignition internal combustion engine, wherein a collision surface is formed in a cavity formed at the top surface of a piston and fuel is injected in the form of a continuous fluid flow from a fuel injector to the collision surface. The timing of the start of the fuel injection from the fuel injector is determined to near the compression top dead center and the initial combustion is performed in the cavity. The fuel colliding with the collision surface is pulled into the squish area due to the reverse squish flow caused when the piston descends after the compression top dead center and the majority of the combustion following the initial combustion is performed in the squish area after the compression top dead center.

摘要： A piston for an internal combustion engine is provided with a reaction chamber for generating radical fuel species during a combustion cycle for use during the next succeeding combustion cycle. The reaction chamber is located adjacent a piston crown recess and is in communication with the main combustion chamber of the engine through discrete orifices that are intended to separately control the supply of fuel and air to the reaction chamber for fuel injected engines and to enhance reaction chamber function in fuel aspirating engines. The discrete fuel and air control orifices are particularly beneficial for use in high swirl, direct injected combustion chambers.
