摘要： A fuel injection system for an internal combustion engine of the type so-called unit injector wherein the overflow of fuel under high pressure from a plunger chamber defines the fuel injection cut-off. In order to perform the sharp cut-off, an overflow passage is increased in cross sectional area, and in order to prevent the overflow from the plunger chamber while the fuel is being charged into it, a flow control means such as a spool type directional control valve is inserted into the overflow passage so that when the fuel is being charged into the plunger chamber the communication between the overflow passage and a fuel tank may be positively interrupted. In addition, in order to prevent the fuel recharge with the resulting secondary injection, a flow control means such as a solenoid operated directional control valve is inserted into a fuel supply line communicating between a fuel delivery source and the plunger chamber such that as long as the fuel injection continues or when the fuel injection is zto be completed, the communication between the plunger chamber and the fuel delivery source may be completely cut off.
摘要翻译：一种用于所谓单元喷射器的内燃机的燃料喷射系统，其中来自柱塞室的高压下的燃料溢出限定了燃料喷射截止。为了进行锐利的切断，溢流通路的横截面面积增大，为了防止在燃料装入其中时从柱塞室溢出的流量控制装置，例如卷轴型方向控制阀被插入到溢流通道中，使得当燃料被充入柱塞室时，溢流通道和燃料箱之间的连通可被肯定地中断。此外，为了防止所得到的二次注入的燃料再充电，诸如电磁操作方向控制阀之类的流量控制装置被插入到燃料供给管线之间，该燃料供应管线在燃料输送源和柱塞室之间连通，使得只要燃料喷射继续或当燃料喷射z完成时，柱塞室和燃料输送源之间的连通可以被完全切断。

摘要： An electromagnetic selector valve for changing the fuel paths between the fuel tank, fuel supply pump and fuel injection pump of an engine is energized by an energization control unit including a monostable multivibrator only for a predetermined time interval just after the engine key switch has been turned off. An on-off valve disposed in the pipe line between the fuel tank and the electromagnetic selector valve or the pipe line between the electromagnetic selector valve and the fuel injection pump, is opened during the time the engine is operating. When necessary, the on-off valve is continuously opened by another energization control unit including a monostable multivibrator for a predetermined time interval just after the engine key switch has been turned off.

摘要： A stopping device for an engine supplied with fuel by a fuel injection pump including a change-over valve, and an actuator for actuating the change-over valve in response to an engine shutdown operation. The change-over valve is movable between a first position to which it moves at engine startup to connect a fuel tank with an inlet of a fuel supply pump driven by the engine and connect an outlet of the fuel supply pump with an inlet of the fuel injection pump, and a second position to which it moves in response to an engine shutdown operation to connect the inlet of the fuel injection pump with the inlet of the fuel supply pump and connect the outlet of the fuel supply pump with the fuel tank. The actuator includes a solenoid and a key switch operative to energize the solenoid to move the change-over valve to the first position in response to an engine startup operation, hold the change-over valve in the first position during engine operation, and de-energize the solenoid to move the change-over valve to the second position in response to an engine shutdown operation.

摘要： The present invention discloses an improved control apparatus for a Diesel engine. The control apparatus includes an auxiliary intake air throttle device as well as a conventional main throttle device, which is actuable and throttles intake air only during engine idling and light-load operation in order to reduce the engine noise. The apparatus is further provided with a fuel metering device for ensuring the precise control on fuel metering when the auxiliary intake air throttle device is actuated so that the engine stall may be prevented.
