INVENTION: FUEL INJECTION SYSTEM WITH AUGMENTED TEMPERATURE SENSITIVE FUEL ENRICHMENT FOR TRANSIENT ENGINE LOADS INVENTOR: E. DAVID LONG Abstract of the Disclosure A fuel injection system for a spark ignited, internal combustion engine employs sensors which measure engine operating parameters to control the duration of actuating pulses applied to at least one fuel injector. One of the sensors measures engine temperature and the pulse duration is increased at lower engine temperatures to compensate for the lower volatility of the fuel at such lower temperatures. The output of a manifold vacuum sensor is differentiated to derive a signal proportional to the fate of increase of engine load and that is used in com- bination with the engine temperature sensor to increase the duration of an injector actuating pulse in amounts proportional to the rate of increase of engine load. The amount of increase in duration of the pulse varies inversely with engine tempera- ture. This allows the enrichment of the fuel charge which normally occurs as an inverse function of engine temperature to be maintained at a level which may produce a leaner steady state air to fuel ratio during engine warm-up and to provide additional enrichment of the fuel charge during periods of increase transient engine load to provide reduced exhaust emissions during warm-up without stalling.
