Method to stop a combustion machine and ease its start

摘要

The method involves interrupting exhaust gas recirculation (9) during rundown of an internal combustion engine (10), and replacing exhaust gases in engine cylinders (3) with fresh air during a rundown of the engine. A throttle valve placed in an intake of the engine is opened during the rundown of the engine and closed immediately prior to ceasing of the engine rotation. Timings of the inlet and exhaust valves coupled to the engine cylinders are adjusted such that both valves are not open at the same time.
