    • PROBLEM TO BE SOLVED: To avoid the transitional deterioration in HC in a stage of the low cylinder temperature, by realizing early activation of a catalyst and HC reduction by after burning by a large ignition timing delay of the ignition timing. SOLUTION: In a cold start of an internal combustion engine for requiring an early temperature rise in a catalytic converter, the ignition timing is set after the compression upper dead center. Fuel injection is divided into two times, and the fuel injection of first time is performed in an intake stroke or a compression stroke, and the fuel injection of second time is performed in an expansion stroke before the ignition timing and after the compression upper dead center. Turbulence in a cylinder is improved by high pressure fuel injection just before the ignition timing, and since propagation of a flame is promoted, stable combustion can be realized. Since the HC increases to the contrary by a shortage of vaporization time of the fuel injection of the second time just after the cold start being very low in the cylinder temperature, a rate of the fuel injection of the second time is initially reduced, and is gradually increased with the lapse of time.

    • PROBLEM TO BE SOLVED: To reduce HC by the premature activation and afterburning of a catalyst by the remarkably large spark-retard angle of an ignition timing and avoid that exhaust system parts are heated to breakable temperatures. SOLUTION: A spark ignition timing is set after a top dead center in a compression stroke when an internal combustion engine is started in a cold state where a premature increased temperature is requested for a catalytic converter. Fuel injection is performed two times during an intake stroke or a compression stroke, and a second fuel injection is performed during an expansion stroke before the ignition timing and after the top dead center in the compression stroke. Since flame propagation is promoted by an increase in disturbance in a cylinder by the injection of a high-pressure fuel immediately before the ignition timing, stable combustion can be realized. To avoid the excessive rise of the temperature of the exhaust system parts, the amount of the injection of the fuel in the expansion stroke is reduced when an exhaust gas temperature reaches a prescribed temperature near an exhaust system breaking temperature to suppress the rise of the temperature.

    • 要解决的问题:通过点火正时的显着大的火花延迟角度,通过催化剂的过早活化和再燃烧来减少HC,并且避免将排气系统部件加热到可破坏的温度。 解决方案:当内燃机在催化转化器要求过早升温的寒冷状态下启动时,在压缩冲程中的上止点之后设定火花点火正时。 在进气冲程或压缩行程期间执行燃料喷射两次,并且在点火正时之前的膨胀冲程期间和在压缩冲程中的上止点之后执行第二燃料喷射。 由于通过在点火正时之前喷射高压燃料,气缸中的扰动增加促进了火焰传播,因此可以实现稳定的燃烧。 为了避免排气系统部件的温度过度上升,当废气温度达到排气系统断开温度附近的规定温度时,膨胀冲程中的燃料喷射量减少,以抑制温度升高 。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To materialize activation of a catalyst at early stage and reduction of HC due to post combustion, and avoid transitional deterioration of HC at a stage of low temperature inside of a cylinder by large retard of ignition timing. SOLUTION: Super retard combustion in which ignition timing is established after compression top dead center and fuel is injected before ignition timing and after compression top dead center is performed at a time of internal combustion engine cold start during which quick temperature rise of a catalytic converter is required. Since turbulence in the cylinder is improved and transmission of flame is promoted by high pressure fuel injection right before ignition timing, stable combustion is materialized. On the other hand, since atomization of spray is not secured and HC creation quantity increases inversely during a very short period of low cylinder temperature right after start, super retard combustion is prohibited and fuel is injected in compression stroke and is ignited BTDC. Cylinder temperature is estimated based on water temperature at a time of start and passing time. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:为了实现早期催化剂的活化和由于后燃烧引起的HC的还原,并且通过大量的点火正时延迟来避免在气缸内的低温阶段的HC的过渡劣化。 解决方案:在压缩上止点和燃料在点火正时之前被注入并且在内燃机冷启动时进行压缩上死点之后建立点火正时的超级延迟燃烧,在此期间内部发动机的快速升温 催化转化器是必需的。 由于在点火正时之前通过高压燃料喷射提高了气缸中的湍流并促进了火焰的传播,因此实现了稳定的燃烧。 另一方面,由于喷雾雾化不能确保,并且在起动后的低气缸温度的非常短的时间段内HC产生量反而增加,所以禁止超级燃烧,在压缩冲程中喷射燃料并点燃BTDC。 气缸温度基于开始和通过时间的水温估算。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To continue a divided injection in a spark retarded state for longer time to increase the temperature of exhaust emission.
      SOLUTION: During the startup of an internal combustion engine in a cold state, the divided injection in which the pulse width of each injection is equal to or larger than the minimum allowable pulse width of injection for securing the stability of combustion is performed in such a manner that an air-fuel mixture the air-fuel ratio of which is leaner than a stoichiometric number is formed in the entire part of a combustion chamber by a first fuel injection, and an air-fuel mixture the air-fuel ratio of which is richer than the stoichiometric number is formed around an ignition plug by a second fuel injection, and a stratified combustion is performed in a spark retarded state to increase the temperature of the exhaust emission. The internal combustion engine comprises a control means 50 for controlling the fuel injection timing and the pulse width of injection. The control means 50 is set in such a manner that the minimum allowable pulse width of injection by the first fuel injection is smaller than the minimum allowable pulse width of injection by the second fuel injection.

    • PROBLEM TO BE SOLVED: To achieve early activation of a catalyst when an internal combustion engine is cold, and to avoid the deterioration of a primary peak of HC. SOLUTION: At cold start of the internal combustion engine requiring early temperature rise of a catalyst converter, ignition timing is set after a compression top dead center, and extremely retard combustion to inject fuel before the ignition timing and after the compression top dead center is performed. Since turbulence inside a cylinder is improved by the high-pressure fuel injection immediately before the ignition timing and flame spread is promoted, stable combustion can be achieved. A fuel injection valve 10 has a tip positioned nearer an exhaust valve 8 in relation to a center of a combustion chamber 5, and is inclined to an intake valve 6 side to inject fuel. Thus, relatively large amount of fuel injected after the compression top dead center is unevenly distributed nearer the intake valve 6 inside the combustion chamber 5, and unburned HC generated in the vicinity of the exhaust valve 8 is reduced. Therefore, the HC primary peak when the exhaust valve 8 is opened is lowered. COPYRIGHT: (C)2007,JPO&INPIT
    • 要解决的问题:为了在内燃机冷时实现催化剂的早期活化,并且避免HC的一次峰的劣化。 解决方案:在需要催化转化器早期升温的内燃机的冷起动时,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极其延迟燃烧以喷射燃料 中心被执行。 由于在点火正时和火焰蔓延之前的高压燃料喷射提高了气缸内的湍流,可以实现稳定的燃烧。 燃料喷射阀10具有相对于燃烧室5的中心更靠近排气门8的尖端,并且与进气门6侧倾斜以喷射燃料。 因此,在压缩上止点之后喷射的相当大量燃料不均匀地分布在燃烧室5内的进气门6附近,并且在排气门8附近产生的未燃HC降低。 因此,排气门8打开时的HC主峰降低。 版权所有(C)2007,JPO&INPIT

    • PROBLEM TO BE SOLVED: To avoid thermal degradation of a catalyst due to an excessively high temperature while attaining early activation of the catalyst and HC reduction by after-burning with a considerable delay of ignition timing. SOLUTION: At the cold start of an internal combustion engine which requires the early temperature rise of a catalytic converter, the ignition timing is set after the compression top dead center, and super retard combustion of injecting fuel before the ignition timing and after the compression top dead center is performed. Turbulence in a cylinder is improved by high pressure fuel injection immediately before the ignition timing, and flame propagation is accelerated to achieve stable combustion. In this super retard combustion, an exhaust temperature becomes very high, and if it continues to the complete active temperature of the catalyst, there is a problem of thermal degradation. A top dead center injection operation mode is thereby released in a predetermined stage before complete activity. COPYRIGHT: (C)2007,JPO&INPIT
