Abstract
A method of controlling an engine during an engine startup or shutdown condition includes operating a valve to open a port of a combustion chamber to allow fluid to flow between the combustion chamber and the port for at least one entire engine cycle. The method also includes preventing combustion of fuel during a combustion stroke of the at least one engine cycle. The engine cycle occurs during the engine startup or shutdown condition.
