Abstract: An accumulator type fuel injector system including an arrangement for changing the bias on the injector valve as the pressure of the fuel increases so as to reduce the sensitivity of the device to pressure variations as may occur under low speed operation. In the embodiments, the arrangement for changing the bias comprises either an elastomeric or a coil spring that acts against the main biasing spring of the injector valve and which are responsive to pressure in the accumulator chamber. In addition, a tapered discharge port arrangement is incorporated for the injector nozzle so that proportionately greater amounts of fuel will be discharged as the lift of the injection valve increases.

Abstract: A fuel injection system and method for a fuel injected engine of the multi cylinder type for minimizing variations in crankshaft speed due to variations in individual cylinder to cylinder firing. These variations are compensated for by changing the fuel injection and specifically the duration of the fuel injection. The engine speed is measured for each cylinder either by the time required to reach top dead center from a predetermined angle, the time to reach bottom dead center from a predetermined angle, or from the average speed.

Abstract: A high pressure fuel injection device including an accumulator type fuel injection nozzle for an internal combustion engine. High pressure fluid is delivered to the accumulator chamber by a reciprocating pump and the amount of fuel discharged is controlled by controlling the discharge pressure of the high pressure pump. This is done by varying the timing phasing of the pump.
