Immediately following the cranking of an engine, a fuel step is provided ( ). The fuel step ( ) is an amount of fuel that is less than the cranking fuel amount for an engine, and is provided for a fixed time period ( ) once a transition from crank to run in the engine is detected ( ). Engine start-up is improved by maintaining engine speed to prevent the engine from stalling, thereby reducing the necessity to restart the engine.

Method and apparatus for delivering fuel to an engine

An electronic engine control system includes a P-I-D governor ( ) that provides a data output having a proportional component (P), an integral component (I), and a derivative component (D), each of which is derived from closed-loop processing of engine speed error data (NERR). A Cold Adder function ( ) provides a further component to the data output, that further component having a data value that is based on engine temperature (EOT) and on elapsed engine running time since the engine was last started.
