Abstract
A single spot fuel injector is energized only twice per revolution of the crankshaft of the engine so that under given operating conditions the injections coincide with the TDC and BDC positions of a piston of a selected cylinder of the engine. Under higher engine speed operation, the injection timing is advanced to improve the fuel distribution to the cylinders. When the engine operates at an engine speed below a predetermined level it is possible for the injector to be energized three times per revolution of the crankshaft.
