A miller cycle engine system is provided, which includes a motorized supercharger, and a miller cycle engine (having low compression and high explosion) having the motorized supercharger mounted thereon to improve a low-revolution performance of an engine using a scavenging phenomenon due to an operation of a variable valve device (variable valve timing, variable valve lift and variable valve duration) during an operation of the motorized supercharger and to improve a fuel efficiency through down-speeding of a gear ratio of a vehicle. |
