摘要： A stratified-charge combustion chamber system for a direct-injection spark-ignited (DISI) engine with a swirl-type airflow. An asymmetrical combustion bowl design in the top wall of the piston provides a wide area on the downstream side of the swirl flow and a harbor area upstream of the swirl flow in a direction further away from the fuel injector. The edge of the combustion bowl is comprised of smoothly-connected curves with large radii, except for the curve connecting the wide and harbor areas, which has a small radius. The vertical cross-sections of the bowl also have large radii in order to guide the air-fuel mixture and rebounded fuel droplets toward the spark plug and prevent dead regions for the fuel. The precise position of the spark plug in the harbor area can be adjusted as desired within a certain range to improve ignitability of the air-fuel mixture.

摘要： A system and method for controlling combustion in a direct injection spark ignition internal combustion engine inject fuel directly into a combustion chamber through an injector having an ignition jet or group of jets positioned primarily to support stratified charge formation and a mixing jet or group of jets positioned primarily to support homogeneous charge formation. The ignition jet(s) and mixing jet(s) produce discernibly different yet well connected fuel clouds within the cylinder to provide stable combustion and reduce cylinder wall wetting by appropriate selection of the axial/longitudinal angles and radial/circumferential angles of the ignition and mixing jets.

摘要： A method is presented for improving performance of direct injection spark ignition internal combustion engines at high load conditions by increasing the degree of homogeneity of the air-fuel mixture during the intake stroke of the engine. The improved performance is achieved by adding a deflector designed to reduce intake air impinging upon the fuel spray and deflecting it to the intake side of the combustion chamber, thus facilitating better fuel circulation throughout the combustion chamber. This method improves engine performance at high load engine operating conditions.

摘要： A stratified-charge combustion system design for direct-injection spark-ignited engines with the piston bowl in the exhaust-valve side. The air flow from the inlet valve provides a normal tumble in cylinder air flow. The fuel injector is positioned on the intake-valve side of the combustion cylinder and forms a charge stratification in the combustion chamber. With the piston bowl on the exhaust-valve side, the distance for spray penetration of the fuel from the injector is extended. The rate of fuel spray penetration in the combustion chamber is reduced by counter air flow against the fuel spray. The air-fuel mixture is moved upwardly to the area of the spark plug by the tumble air flow for ignition. The invention provides less piston bowl wall wetting which results in less soot formation and less emissions of undesirable hydrocarbons.

摘要： A stratified charge is formed in a direct injection engine by injecting fuel at a predetermined velocity, a predetermined droplet size, and forming the injected fuel with a hollow cone having a predetermined initial cone angle. The injected fuel thereby shallowly penetrates the combustion chamber so as to float therein to reduce wall-wetting and subsequent soot formation. A substantially flat top piston forms the injected fuel into a ball-shaped kernel during a compression stroke of the engine. The ball-shaped kernel remains substantially unmixed with the inducted air, thereby producing the stratified charge. The continued motion of the piston causes the ball-shaped kernel to move toward the spark plug for ignition.
摘要翻译：在直接喷射发动机中通过以预定速度喷射燃料，预定的液滴尺寸，并用具有预定的初始锥角的中空圆锥形成喷射的燃料，形成分层的电荷。喷射的燃料因此浅地穿透燃烧室以便在其中漂浮以减少壁湿润和随后的烟灰形成。在发动机的压缩冲程期间，基本平坦的顶部活塞将喷射的燃料形成为球形的内核。球形内核基本上与引入的空气不混合，从而产生分层电荷。活塞的持续运动导致球形内核朝着火花塞移动以点燃。
