Methanol as an alternative fuel is considered to be one of the most favorable fuels for internal combustion engines. In this paper, knock in a high compression ratio spark-ignition (SI) methanol engine was studied by using multi-dimensional simulation. Knocking combustion under various engine...

A novel common-rail type DME injector has been proposed by State Key Laboratory of Engines. The injector employs impact principle to enlarge its electromagnetic force, and thus has no plunger matching parts. The sealing and wear problems brought by plunger can be avoided when the injector...

An opposed-piston hydraulic free piston engine operating with homogenous charge compression ignition (HCCI) combustion, has been proposed by State Key Laboratory of Engines as a means of significantly improving the IC engine’s cycle thermal efficiency and lowering exhaust emissions. Single and...

Knocking combustion in spark-ignition (SI) engines is an abnormal combustion phenomenon which can constrain the engine performance and thermal efficiency. It can also result in severe permanent engine damage under certain operating conditions. This paper systematically reviews the engine knock...
