Abstract
An electronic fuel control system for an internal combustion engine is disclosed capable of providing an enriched fuel/air mixture to the engine as a function of the engine's temperature and the engine's load during the transient warm up period. The fuel control unit embodies a full load warm up enrichment circuit controlling, in response to engine temperatures below a predetermined temperature and engine loads as determined from the pressure in the engine's intake manifold, the quantity of fuel being delivered to the engine. In the preferred embodiment the full load warm up enrichment circuit is a current sink sinking a portion of the current charging the injection timing capacitor in the electronic control unit to increase the duration of the generated injection fuel delivery pulses.
