In-cylinder flow field characteristics and evolution mechanism of unthrottled gasoline engine with Early Intake Valve Closure (EIVC) under different operating conditions

Case Studies in Thermal Engineering
The efficiency improvement of traditional gasoline engines is hindered by a limited compression ratio due to knock and severe pumping losses caused by fixed valve lift. Unthrottled technology has emerged as a solution relying on variable valve mechanisms.
