A pressure pulse injector can include an accumulator, valves, and a control system. The control system can receive parameters, including a maximum pressure and target distance, about a flowline. The control system can determine a change in pressure for a p...

An electronically controlled fuel injection valve can independently control the time to inject fuel and the amount of fuel to be injected in response to a control signal sent from the operating condition of an engine unlike a traditional mechanical fuel in...

The fuel injector valve for an internal combustion engine has a tubular nozzle (44) with a conical valve seat (34) at the tip. The end (33) of the valve needle (20) fits into the valve seat and an annular gap (38) surrounds the needle. Fuel flows through t...

A fuel injector (50) which has a double solenoid (138,140) three-way or four-way spool valve (162,118) that controls the flow of a working fluid that is used to move an intensifier piston (84) of the injector (50).
