A method of fuel injection, comprising constructing an hydraulic behaviour profile by fuel pressure measurement, using the hydraulic behaviour profile to predict fuel pressure that will prevail in a fuel injector during an injection event, and supplying a ...

The method involves detecting a signal from a pressure sensor (3) and integrating the signal during a specified time period. An integrated value is multiplied by a factor, and an operating pressure is added to the multiplied value. The pressure is detected...

Fuel injection system (1) of the common rail type provided with a high-pressure pump (4), which supplies fuel to a common channel (3) that in turn supplies a series of injectors (2), and with a control unit (7), which is capable of keeping the pressure of ...

The present invention proposes a fuel pressure control apparatus for a high-pressure fuel injection system which sufficiently reduces a fuel pressure in an accumulator line (20) while preventing the high-pressure fuel injection system from being adversely ...

A rapid-response solenoid-operated fuel injector (1) for diesel engines is provided which includes a solenoid-operated valve member (21) and a needle valve (12). The solenoid-operated valve member (21) selectively establishes fluid communication between a ...
