Abstract:
1. A system for starting or restarting an internal combustion engine via selective combustion, comprising: at least one sensor configured for determining the angular position of a rotatable member in the engine at any rotational position of the rotatable member; a fuel injection system operable to provide determined amounts of fuel to combustion chambers in the engine; an ignition system operable to ignite the fuel air mixture resulting from the injection of the determined amounts of fuel into respective combustion chambers; an engine control unit operable to determine, from the at least one sensor, the state and position of the pistons in the engine and the volume of the respective combustion chambers formed by the pistons and to select at least one combustion chamber for selective combustion, the engine control unit operable to determine the amount of fuel to be provided to each selected combustion chamber and to have the injection system inject the determined amounts of fuel into each selected combustion chamber and to have the ignition system ignite the resulting fuel air mixture in each selected combustion chamber, the combustion of the fuel air mixture in the at least one selected combustion chamber rotating the crankshaft of the engine to start normal operation of the engine.
