摘要： There is provided a spark ignited internal combustion engine having a geometric compression ratio of 13.0 or greater. The engine comprises combustion chambers having a cylinder stroke volume of 0.3 liter or greater, with the spark plug in the chamber ceiling having its spark point in the combustion chamber, and a cavity being formed on the top surface of the piston. At least part of the cavity defines a spherical surface that a hypothetical sphere having its center at the spark point contacts when the piston is at top dead center. The cavity is formed so that V2/V1≧0.31, where V1 is top-dead-center combustion chamber volume, and V2 is the volume of the part of the hypothetical sphere not interfering with the combustion chamber floor or ceiling at top dead center. The flame thus spreads with less interference, shortening combustion duration and reducing fuel consumption.
摘要翻译：提供几何压缩比为13.0以上的火花点火式内燃机。发动机包括具有0.3升或更大的气缸行程体积的燃烧室，其中室顶部中的火花塞在燃烧室中具有其火花点，并且在活塞的顶表面上形成空腔。空腔的至少一部分限定了球形表面，当活塞处于上止点时，具有其在火花点处的中心的假想球接触。空腔形成为V2 /V1≥0.31，其中V1是上死点燃烧室体积，V2是假想球体部分的体积，不会干扰上死点处的燃烧室地板或天花板。因此，火焰以较少的干扰扩散，缩短燃烧持续时间并降低燃料消耗。

摘要： When a specific condition requiring a rise in exhaust gas temperature is satisfied, a required fuel amount to be injected from an injector (21) is injected in a split manner, such that the fuel injection is divided to: a main injection (X1) to be initiated a given period before a compression top dead center; an auxiliary injection (X2) to be initiated after initiation of auto-ignited combustion of an air-fuel mixture consisting of air and the fuel injected by the main injection (X1) and before an assumed peak timing (Pk′) of a heat release rate (RH) from the combustion based on the main injection (X1); and a post injection (X3) to be initiated after the assumed peak timing (Pk′) and before completion of combustion based on the main injection (X1) and the auxiliary injection (X2). This makes it possible to raise an exhaust gas temperature while sufficiently ensuring auto-ignitability and fuel economy performance.

摘要： Disclosed is an engine control system which is designed to allow homogeneous-charge compression ignition combustion to be performed in an HCCI region (R) defined as an engine operating region including at least a partial-load range of an engine. In a low load zone (R1) of the HCCI region (R), a lift amount of an intake valve (11) is set to a first predetermined value, and an exhaust valve (12) is allowed to start being opened during an intake stroke at a given timing later than an opening timing of the intake valve (11). Further, in the medium load zone of the HCCI region, the lift amount of the intake valve (11) is gradually increased up to a second predetermined value greater than the first predetermined value, along with an increase in an engine load. The engine control system is capable of adequately controlling an amount of burned gas to be introduced into a cylinder, depending on the engine load to allow the HCCI combustion to be adequately performed in a wider engine load range.

摘要： A combustion control apparatus is configured for a direct-injection spark-ignition internal combustion engine. The combustion control apparatus selects an extremely retarded combustion mode while the internal combustion engine is in a predetermined operating state. In the extremely retarded combustion mode, the combustion control apparatus sets ignition timing to be after compression top dead center, and sets fuel injection timing to be before the ignition timing and after compression top dead center. The combustion control apparatus inhibits the extremely retarded combustion mode while an exhaust purifier of the internal combustion engine is in a predetermined cold state.
