摘要： PROBLEM TO BE SOLVED: To improve stability in combustion by forming air-fuel mixture in the vicinity of an ignition plug stably and suppress reduction of tumble stream to the minimum extent.
SOLUTION: A bottom face 22a of a substantially rectangular recessed part 22 on a crown face of a piston 4 forms a curved face being substantially parallel with a central axial line of a piston pin along tumble stream. A protruding bar part 25 being parallel with the central axial line of the piston pin is formed in a substantially central part of the bottom face 22a just below the ignition plug 7, and rising parts 25a, 25b on its intake valve side and exhaust valve side form circular arc faces. Radius of curvature of the rising part 25b on the exhaust valve side is larger than that on the intake valve side. An ascending current going upward occurs when a spray passes above the protruding bar part 25 at stratified lean combustion time, and a part of the spray is guided onto an upper ignition plug side, thereby achieving stable combustion. Since the rising part 25b on the exhaust valve side forms the circular arc face having large radius of curvature, flow of tumble stream at homogeneous combustion time is not obstructed.

摘要： PROBLEM TO BE SOLVED: To improve combustion stability by forming an air-fuel mixture in the vicinity of an ignition plug stably and to minimize reduction of tumbling flow.
SOLUTION: A bottom face 25 of a substantially rectangular recessed part 22 on a crown face of a piston 4 forms a curved face being substantially parallel with a central axis of a piston pin along the tumbling flow. A step part 27 being parallel with the central axis of the piston pin is formed in a substantially central part of the bottom face 25 just below the ignition plug, and a rising part 27a is formed on an intake valve side. A rising stream going upward occurs when a spray passes above the step part 27 at stratified lean combustion time, and a part of the spray is guided onto an upper ignition plug side, thereby achieving stable combustion. Since cut-out parts 28, 28 are provided at both ends of the step part 27 and the bottom face 25 is continuous without a step, flow of the tumbling flow at homogeneous combustion time is not obstructed.

摘要： PROBLEM TO BE SOLVED: To substantialize early activation of a catalyst and HC reduction due to after-burning by drastic delay of ignition timing, and to avoid thermal damage of a catalyst converter due to a rapid temperature rise. SOLUTION: At cold start of an internal combustion engine requiring early temperature rise of a catalytic convertor, ignition timing is set after a compression top dead center, and super retard combustion for injecting fuel before the ignition timing and after the compression top dead center is performed. Since turbulence inside a cylinder is improved due to high-pressure fuel injection immediately before the ignition timing and flame spread is promoted, stable combustion can be realized. In super retard combustion, a high exhaust temperature can be obtained, and when the exhaust temperature is raised immediately after cold start, thermal distortion of the catalyst converter is increased. Therefore, until the catalyst temperature reaches the activation start temperature, the top dead center injection operation mode is prohibited. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题：通过急剧延迟点火正时，实现催化剂的早期活化和由于后燃烧而导致的HC还原，并且避免了由于快速升温引起的催化剂转化器的热损伤。
解决方案：在需要催化转化器早期升温的内燃机的冷启动时，点火正时在压缩上止点之后设定，并且在点火正时之前和压缩顶死后超燃燃烧燃料中心被执行。由于在点火正时和火焰蔓延之前立即由于高压燃料喷射而提高了气缸内的湍流，因此可以实现稳定的燃烧。在超延迟燃烧中，可以获得高排气温度，并且当冷启动后立即升高排气温度时，催化剂转化器的热变形增加。因此，在催化剂温度达到激活开始温度之前，禁止上止点注入动作模式。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To reduce HC owing to premature activation and after burning of a catalyst by a large delay of ignition timing and to avoid thermal damage of a catalytic converter owing to excessively high temperature. SOLUTION: In cold start of an internal combustion engine wherein an early temperature rise of the catalytic converter is required, the ignition timing is set to be after compression top dead center and super-retard combustion is performed by injecting fuel immediately before the ignition timing and after the compression top dead center. Turbulence in a cylinder is improved by the high pressure fuel injection immediately before the ignition timing, flame spread is promoted and therefore stable combustion is obtained. Although very high exhaust temperature is obtained in the super-retard combustion, the exhaust temperature gets excessively high when load is increased in vehicle starting, turning-on of an auxiliary or the like and there is fear for the thermal damage of the catalytic converter. The super-retard combustion is therefore cancelled immediately upon detection of a predetermined load rise. COPYRIGHT: (C)2007,JPO&INPIT
