METHOD AND SYSTEM FOR STARTING OR RESTARTING AN INTERNAL COMBUSTION ENGINE VIA SELECTIVE COMBUSTION
First Claim
1. A system for starting or restarting an internal combustion engine via selective combustion, comprising:
- at least one sensor for determining the angular position of a rotatable member in the engine;
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.

Abstract
A selective combustion starting system and method selectively provides a proper amount of fuel to one or more combustion chambers in an internal combustion engine. The particular combustion chambers selected depend upon the state of the piston of the combustion chamber and the volume of the combustion chamber, which is dependent upon the position of the piston. Once proper amounts of fuel have been provided to the one or more combustion chambers, the resulting fuel air mixture in the combustion chambers is ignited and combusts to rotate the crankshaft of the engine to commence normal operation of the engine.
