    • 要解决的问题:提供一种用于执行端口喷射和多气缸喷射的燃料喷射装置,同时抑制与气缸喷射量的减少相关联的燃烧状态恶化。解决方案:燃料喷射装置包括端口喷射 用于将燃料喷射到进气口中的阀,以及用于将燃料喷射到燃烧室中的气缸喷射阀。 它通过端口喷射阀执行端口注入P1,并通过气缸喷射阀执行多气缸喷射。 当要求减少第一气缸喷射DI1至第三气缸喷射DI3的量时,由于从进气上止点到喷射开始的喷射时间较短,喷射量的减少进一步优先化 。

    • PROBLEM TO BE SOLVED: To improve air-fuel ratio controllability when starting, by simultaneously using intake passage injection by considering a characteristic of alcohol fuel, while securing startability by cylinder injection.SOLUTION: An ECU 50 injects fuel only from a cylinder injection valve 28 in at least a first cycle when starting an engine, and simultaneously uses fuel injection of an intake passage injection valve 26 on and after a second cycle. When an alcohol concentration in the fuel is a predetermined value or more, a portion of the fuel injected from the intake passage injection valve 26 in the second cycle, is injected from the intake passage injection valve 26 by moving up to the first cycle. Thus, even when the alcohol concentration in the fuel is high, a portion of an intake passage injection quantity of becoming excessive in the second cycle, is moved up to the first cycle, and this fuel can be burnt in the second cycle by a transport delay, and quantity of fuel to be burnt in the respective cycles can be properly controlled.
    • 要解决的问题:为了提高起动时的空燃比控制性,通过考虑醇燃料的特性同时使用进气通道喷射,同时通过气缸喷射确保启动性。解决方案:ECU50仅从气缸喷射阀28喷射燃料 在起动发动机时的至少第一循环中,并且同时在第二循环之
      间和之后使用进气通道喷射阀26的燃料喷射。 当燃料中的酒精浓度为预定值以上时,从进气通道喷射阀26在第二循环中喷射的燃料的一部分从进气通道喷射阀26通过向上移动直到第一循环来喷射。 因此,即使当燃料中的醇浓度高时,在第二循环中进入通道喷射量变得过大的部分被移动到第一循环,并且该燃料可以在第二循环中通过运输 可以适当地控制延迟和在各循环中燃烧的燃料量。

    • PROBLEM TO BE SOLVED: To excellently hold combustibility, even if an estimation error of an alcohol concentration exists when starting.SOLUTION: An ECU 50 injects fuel exceeding an allowable limit in a transport delay out of fuel tried to be injected from an intake passage injection valve 26, from a cylinder injection valve 28 as a transport delay increase quantity, when simultaneously using intake passage injection and cylinder injection when starting an engine. Thus, even when an estimation error is caused when estimating an alcohol concentration in the fuel, a cylinder injection quantity for improving startability can be increased. Thus, influence of the estimation error on an intake passage injection quantity and a transport delay increase quantity is restrained, and starting time combustibility can be excellently held. A variation in the air-fuel ratio and the deterioration in exhaust emission caused by the transport delay of the intake passage injection are restrained, and the startability and an exhaust characteristic can be improved.
    • 要解决的问题:即使在启动时存在酒精浓度的估计误差,也能够保持可燃性。解决方案:ECU 50将超过允许极限的燃料从运行延迟中喷出,从尝试从进气通道注入喷射的燃料 阀26,作为输送延迟增加量,来自气缸喷射阀28,同时在起动发动机时同时使用进气通道喷射和气缸喷射。 因此,即使当估计燃料中的酒精浓度时发生估计误差时,也可以提高用于提高启动性的气缸喷射量。 因此,抑制了估计误差对进气通道喷射量和运送延迟增加量的影响,并且可以良好地保持起动时间可燃性。 抑制由于进气通道喷射的输送延迟引起的空燃比的变化和废气排放的劣化,能够提高起动性和排气特性。

    • PROBLEM TO BE SOLVED: To suitably control ignition timing for catalyst warmup on the basis of an alcohol concentration even if the alcohol concentration in fuel is varied.SOLUTION: The ECU 50 executes second catalyst warmup control after first catalyst warmup control is executed at the ignition retard angle permissible number α after starting the engine. In the first catalyst warmup control, an ignition action is executed while an amount of a retard angle of ignition timing is reduced than that of the second catalyst warmup control. An amount of an ignition retard angle is considerably retarded on the second catalyst warmup control on the basis of the alcohol concentration. Even though errors are contained in an acquired value of the alcohol concentration caused by refueling, such the errors can be prevented from being reflected to the ignition timing at an early stage of the catalyst warmup control. Consequently, catalyst warmup control can be performed at an optimal state in the internal combustion engine using alcohol fuel, and a catalyst can be effectively warmed up.
    • 要解决的问题:为了适当地控制基于醇浓度的催化剂预热的点火正时,即使燃料中的醇浓度变化。 解决方案:ECU50在启动发动机之后以点火延迟角许可数α执行第一催化剂预热控制之后执行第二催化剂预热控制。 在第一催化剂预热控制中,当点火正时的延迟角的量比第二催化剂预热控制的点降低时,执行点火动作。 基于醇浓度,第二催化剂预热控制上的点燃延迟角的量显着延迟。 即使在由加油引起的酒精浓度的获取值中包含误差,因此可以防止在催化剂预热控制的早期阶段反映到点火正时的误差。 因此,可以使用醇燃料在内燃机的最佳状态下进行催化剂预热控制,能够有效地预热催化剂。 版权所有(C)2013,JPO&INPIT
