Abstract
A method and system to start an internal combustion engine from rest is disclosed. The engine has intake and exhaust valves in each cylinder in which actuation of such valves is independent of engine rotation. The engine also has a fuel injector and a spark plug disposed in each engine cylinder. The intake and exhaust valves are closed in one engine cylinder; fuel is sprayed into such cylinder; the spark plug is fired in such cylinder. Additionally, a second cylinder is identified in which the intake and exhaust valves are closed, fuel is sprayed, and a spark is fired prior to engine rotation.
