TLDR
In this article, a control operation for extending an opening period of a change-over valve which is adapted to switch a low-pressure accumulator and a high pressure accumulator from one to the other during a fuel injection operation is carried out to increase a flow rate of a fuel supplied to the low pressure accumulators and thereby reduce the pressure in the high pressure accumulation.Abstract:
During a transitional operation of an engine in which an engine load is changed suddenly from a high load to a low load, a control operation for extending an opening period of a change-over valve which is adapted to switch a low-pressure accumulator and a high-pressure accumulator from one to the other during a fuel injection operation is carried out to increase a flow rate of a fuel supplied to the low-pressure accumulator and thereby reduce the pressure in the high-pressure accumulator, whereby a response delay of the fuel pressure in the high-pressure accumulator is minimized. During a transitional operation of the engine in which the engine is in an accelerated operation, the change-over valve is kept open until the fuel pressure in the low-pressure accumulator, which is connected to the portion of a fuel passage which is on the downstream side of the change-over valve adapted to switch the low-pressure accumulator and high-pressure accumulator from one to the other during a fuel injection operation, reaches an indicated level, and until a predetermined period of time elapses after the fuel injection finishing time, whereby the formation of a fuel pressure in the low-pressure accumulator is promoted to obtain injection condition suiting the operating condition of the engine.read more

Fuel-injection device for internal-combustion engines
TL;DR: In this paper, a solenoid valve is used to detect the stroke moment of the needle needle as a precise signal of the commencement and termination of the injection and transmits it to the control device, where this actual value is compared with a desired value from performance characteristics and, if necessary, results in a correction of the controlling of the valve.
