To discover performance advantages of modified elliptical bearing, traditional elliptical bearing and cylinder bearing are compared with it under same conditions.

The experimental investigation of the effect of fuel additives on HCCI combustion process was carried out on a 4-cylinder diesel engine of which the fourth cylinder was modified to run in HCCI mode.

The device thoughts and modification progress that modified one cylinder with high pressure, condensing steam turbine to a extraction and supplying heater ones are introduced.
