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.

KIT researchers developing low-pressure carbonitriding process for hardening steel with methylamine; applications in downsized engines

Green Car Congress

Steels hardened in this way are suited for use in components subjected to high mechanical and thermal loads in downsized, energy-efficient and low-emission engines of the future. Combustion engines still have potential to save energy and reduce emissions; a current trend is to use downsized engines of the same or even increased power. Diesel injection systems have to reach higher injection pressures and improved injection accuracies in order to meet the requirements of downsizing.
