摘要： A control device for a fuel injection valve includes a drive circuit that controls open/close operation of the fuel injection valve by passing an exciting current through a solenoid of the fuel injection valve and an ECU that reduces a peak current value as a fuel pressure in a delivery pipe at timing of a start of energization of the fuel injection valve decreases. The ECU reduces the peak current value as an amount of fuel discharged from a high-pressure fuel pump to the delivery pipe reduces.

摘要： An electronic control unit that calculates an injection standby period, which is a period from an energization start point of the solenoid to a point at which the fuel injection valve opens, and adjusts an energization period of the solenoid in accordance with the calculated injection standby period. The electronic control unit of the control apparatus for a fuel injection valve then measures a reference fall detection period, which is a period from the energization start point to a reference fall detection point, and sets the injection standby period to be longer as the reference fall detection period is longer. Here, the reference fall detection point is a point at which the excitation current detected by the current detection circuit falls below a reference current value, which is smaller than a peak current value, while the excitation current decreases after reaching the peak current value.

摘要： A needle has a large-diameter portion, an outer diameter of which is larger than that of a shaft portion of the needle. A needle-side tapered surface is formed at the large-diameter portion on a valve closing side thereof, wherein the needle-side tapered surface is inclined by a needle angle with respect to a center axis of the needle. A core-side tapered surface is formed at a movable core, wherein the core-side tapered surface is inclined by a core angle with respect to the center axis of the needle. The needle and the movable core are brought into contact with each other via the needle-side and the core-side tapered surfaces. The needle angle and the core angle are made to be equal to each other.

摘要： An object of this invention is to appropriately control the state of a corona discharge in accordance with an exhaust air-fuel ratio, and always purify particulate matter (PM) in exhaust gas efficiently. An engine is equipped with a corona discharge-type exhaust emission control device. The exhaust emission control device purifies PM in exhaust gas by generating a corona discharge between a center electrode and an earth electrode. When the air-fuel ratio is in a rich region, an ECU controls an applied voltage that is applied between the electrodes. It is thereby possible to obtain a maximum PM purification rate while preventing an arc discharge. When the air-fuel ratio is in a lean region, a discharge current flowing between the electrodes is controlled. It is thereby possible to suppress power consumption while compensating for a decrease in the PM purification rate caused by a reduction in the PM amount in the exhaust gas.

摘要： An objective of the present invention is to stabilize the fuel injection amount for each cylinder and to execute fuel injection control accurately in a single-pressure-feed dual-injection type alcohol fuel injection system. An engine includes two injection valves and and a single-pressure-feed dual-injection type fuel supply system. The fuel supply system is configured such that fuel is injected sequentially in two cylinders during the pressure-feed-interval period from the execution of one fuel pressure-feed operation to the execution of the next fuel pressure-feed operation. If the alcohol concentration in the fuel is higher than a predetermined determination value γ at a startup operation time, an ECU executes only a cylinder injection for the first of the two cylinders described above, and executes both an intake passage injection and a cylinder injection for the second cylinder. Thus, even if the fuel pressure decreases due to the fuel injection for the first cylinder, the required fuel injection amount can be reserved for the second cylinder.
摘要翻译： 本发明的目的是稳定每个气缸的燃料喷射量，并且在单压进料双注射型酒精燃料喷射系统中精确地执行燃料喷射控制。 发动机包括两个喷射阀和一个单进料双注射型燃料供应系统。 燃料供给系统被构造成使得在从执行一个燃料加压操作到执行下一次燃料加压操作的压力进给间隔期间，将燃料依次注入两个气缸中。 如果燃料中的酒精浓度高于启动操作时间的预定判定值γ，则ECU仅执行上述两个气缸中的第一个气缸的气缸喷射，并且执行进气通道喷射和气缸喷射 第二缸。 因此，即使燃料压力由于第一气缸的燃料喷射而降低，也可以为第二气缸保留所需的燃料喷射量。
