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...

The thermal management systems using EG-based phase change materials (PCMs) can provide power batteries with a proper operating temperature, slow temperature rise rate and uniform temperature distribution. In this study, a systematical investigation on the effects of thermo-physical properties...

A LiNO3/KCl-expanded graphite (EG) composite phase change material (PCM) was prepared for solar thermal energy storage application at high temperature (∼200°C). In such composite material, eutectic system LiNO3/KCl is characterized by high phase change latent heat and EG serves as the heat...

Experimental studies have been performed to investigate the thermal performances of woks fabricated from materials with different thermal conductivities and surface emissivities. A pre-mixed air/butane flame impinged vertically upwards upon a flat impingement-plate's (to simulate the wok's...
