Split injection Miller cycle with boost decreases knock tendency and increases torque in downsized engine

Green Car Congress

Researchers at Tianjin University in China report that combing split injection to the Miller cycle with boost pressure can effectively decrease the knock tendency and increase the engine torque in a downsized spark-ignition engine. The current development of downsized spark ignition (SI) engines with boost pressure is a proven way of increasing the thermal efficiency and reducing CO 2 emissions. Engines Fuel Efficiency
