Abstract
A distributor pump type fuel injection system for a diesel engine wherein the pump is driven by the engine and the control of the timing and metering of fuel being delivered to each cylinder of the engine is controlled by a single electromagnetic solenoid device. The control system includes a distribution head for distributing pulses of fuel to each cylinder, the control of the fuel to the cylinder, both metering and timing, being controlled by the above-mentioned single electromagnetic control device. The fuel system includes a metering chamber and a timing chamber, the two chambers being separated by a free piston. In the control system to be described, fuel is premetered into the metering chamber, the quantity of fuel therein being controlled by the duration of energization of the control valve during the metering portion of the cycle. The time of injection of the premetered fuel is similarly under the control of the control valve and is initiated upon energization of the control valve.
