摘要:
A system and method to control engine valve timing to during the start of an internal combustion engine. Electromechanical valves are controlled in a manner to reduce hydrocarbon emissions during the start of an internal combustion engine. The method controls intake valves so that smaller adjustments are made to cylinder spark advance and air-fuel over a range of operating conditions.
