ABSTRACT:
A four cylinder, two cycle crankcase compression, diesel fuel injected engine having an improved injection pump including an integral timer for timing the initiation and duration of fuel injection. A control system and method is disclosed for maintaining uniform running speed during all running conditions while reducing the amount of smoke produced by the engine. The speed uniformity is obtained by selecting a cylinder that deviates from the desired speed and adjusting the fuel injection of the cylinder firing preceding that cylinder on the next cycle. The engine also includes an improved arrangement for determining the timing of an event by measuring the incremental rotational speed of the engine immediately prior to the event to be timed.
