摘要： An engine ECU stores a map in which three regions, that is, a high-temperature region, a low-temperature region, and a region therebetween, are prescribed. The pre-feed time T set when the present condition falls in the region is the longest. An engine ECU executes a program that includes the step of detecting an engine cooling water temperature THW when the start-up of the engine is requested, the step of executing the pre-feed until the fuel pressure P becomes equal to or greater than a fuel pressure threshold value P(TH), and the step of starting the cranking when the fuel pressure P becomes equal to or greater than the fuel pressure threshold value P(TH). Thus, the bad start-up caused by fuel vapor is avoided without operating the fuel pump unnecessarily for a long time.

摘要： A pulsation damper is provided between and in series with a low pressure fuel system pipe and a high pressure pump of a fuel supply system. During startup of an engine, low pressure fuel supplied via the low pressure fuel system pipe is injected from an intake passage fuel injector. When the fuel pressure is equal to or less than a fuel pressure at which good startability can be maintained, the pulsation damper closes off communication between the high pressure fuel system pipe and the low pressure fuel system pipe using the spring force of a spring.

摘要： An engine ECU stores a map in which a region at high temperature and high pressure, a region at low temperature and low pressure, and a region provided therebetween are defined by the relationship between the temperature and pressure of fuel and the saturation fuel vapor pressure of the fuel. The engine ECU executes a program including the following steps: when start-up of the engine is requested, detecting the engine cooling water temperature and the fuel pressure; if the detection results fall into the region, setting a pre-feed time; pre-feeding until the fuel pressure reaches a desired fuel pressure threshold; and when the fuel pressure reaches the fuel pressure threshold, starting cranking. In this way, start-up failure due to fuel vapor can be avoided without unnecessarily actuating a fuel pump.

摘要： A cam for driving a high-pressure fuel pump has a cam profile that is asymmetric for the suction stroke and the ejection stroke. The cam profile is set so that the cam angle for the ejection stroke is greater than the cam angle for the suction stroke. Therefore, even when the cam drive shaft is rotating at a constant speed, the duration of the ejection stroke becomes longer than the duration of the suction stroke. That is, the changing speed of the capacity of a pressurizing chamber becomes less during the ejection stroke than during the suction stroke.
摘要翻译：用于驱动高压燃料泵的凸轮具有用于吸入行程和排出行程不对称的凸轮轮廓。凸轮轮廓被设定为使得用于喷射行程的凸轮角度大于吸入冲程的凸轮角度。因此，即使当凸轮驱动轴以恒定速度旋转时，喷射行程的持续时间也会比吸入行程的持续时间长。也就是说，在排出冲程期间加压室的容量的变化速度变得比在吸入行程期间变化的速度变小。

摘要： During the idling state, the number of times of injecting fuel per performance of the fuel delivery from a high-pressure fuel pump is decreased or increased. If the number of times of injecting fuel per performance of the fuel delivery is decreased, the amount of fuel that needs to be delivered by one performance of the fuel delivery is reduced, so that the timing of starting to close an electromagnetic spill valve can be delayed. Therefore, the lift of a plunger for 1° rotation of a cam (i.e., cam speed) at the time of closure of the electromagnetic spill valve decreases, so that the force applied from fuel to the electromagnetic spill valve in the valve closing direction decreases. If the number of times of injecting fuel per performance of the fuel delivery is increased, the noises produced at the time of closure of the electromagnetic spill valve increase because the timing of starting to close the spill valve is advanced to increase the amount of fuel delivered by one performance of the fuel delivery. However, the number of times of closing the electromagnetic spill valve during a predetermined period decreases, so that the number of occurrences of the valve closure noises decreases.
摘要翻译：在怠速状态下，从高压燃料泵执行燃料输送的燃料喷射次数减少或增加。如果每次执行燃料输送喷射燃料的次数减少，则通过燃料输送的一次性能需要输送的燃料量减少，使得开始关闭电磁溢流阀的时间可以是延迟。因此，在关闭电磁溢流阀时凸轮1°旋转的柱塞（即凸轮转速）的提升减小，使得从关闭方向的燃料向电磁溢流阀施加的力减小。如果每次执行燃料输送喷射燃料的次数增加，则在电磁溢流阀关闭时产生的噪声增加，因为开始关闭溢流阀的时间被推进以增加输送的燃料量通过一次表现燃料输送。然而，在预定时间段期间关闭电磁溢流阀的次数减少，使得阀关闭噪声的发生次数减少。

摘要： A high-pressure pump (50) is provided which is drivingly connected to an engine output shaft (1) and delivers fuel to an injector (4) through a delivery pipe (5) based on the rotation of the output shaft (1). The high-pressure pump (50) includes an electromagnetic valve (50b) that adjusts, based on the engine operating state, a fuel delivery amount within an adjustable range that changes according to a rotation speed of the engine output shaft (1). When an abnormality is detected in the electromagnetic valve (50b), the rotation speed of the engine output shaft (1) is restricted to equal to or less than a reference engine speed (NT).
