Homogeneous Charge Compression Ignition Combustion and Exhaust Characteristics of a Common-rail Diesel Engine

  • 발행 : 2005.09.01

초록

An experimental study on homogeneous charge compression ignition combustion with direct fuel injection was conducted using a single cylinder common-rail diesel engine. To improve the homogeneity of fuel-air mixture, the premixed fuel (gasoline) was injected into premixing chamber and the diesel fuel was injected into the combustion chamber as an ignition source for the gasoline premixture. The experimental results show that soot emissions were dramatically reduced with the increase of fuel premixing ratio, however incomplete products such as HC and CO increased with the increase of the premixed ratio. Earlier injection of Dl diesel fuel increased the IMEP with the decrease of HC and CO concentrations.
