The thermodynamic analysis of an electrically supercharged Miller Cycle gasoline engine with early intake valve closing

Abstract: Electric superchargers are able to improve the thermodynamic process of gasoline engines by selfadapting running state to dominate intake air in all operation conditions. This paper proposes a novel approach for electrically supercharged Miller Cycle with early intake valve closing based on thermodynamics to settle the fuel economy problem of gasoline engines at low load operations by taking advantages of the domination of electric superchargers to intake air. Electrically supercharged Miller Cycle with early … Show more

“…The Miller cycle, which has recently been widely applied to passenger cars and ships, is an effective solution for improving the thermal efficiency of gasoline engines and lowspeed diesel engines [14]. The expansion ratio of the engine is larger than the compression ratio (CR) under the Miller cycle by making the intake valves close (IVC) before or after the bottom dead center, thereby improving thermal efficiency [14][15][16]. A thermodynamic analysis of a Miller cycle gasoline engine with early intake valve closing (EIVC) was conducted by CHEN et al [16].…”

“…As the main source of power for passenger vehicles, gasoline engines have played a pivotal role worldwide for a long time. With the increasingly stringent fuel consumption regulations, more and more technologies of the gasoline engine are being studied to improve the fuel economy performance, such as high-compression-ratio technology, fuel injection technology, EGR technology, variable valve technology (VVT), supercharging technology, etc. Among them, the combination of DVVT and high-compression-ratio technology enables the engine to work in the Miller cycle or Atkinson cycle, greatly improving the fuel economy of the gasoline engine, which has become one of the current mainstream technical solutions and realized mature industrial application. At the same time, many scholars have conducted research on this technical solution, and analyzed the effect of Miller cycle combined with high compression ratio on gasoline engine combustion and thermal efficiency improvement. Compared to the original production engine with CR 9.3, the fuel economy is improved at low load by 7.4% after the application of CR12.0 and EIVC . The authors have studied the Miller cycle of turbocharged gasoline engines before.…”
