Abstract

The super-high pressure common rail system was designed innovatively for improving the fuel atomization characteristic of high power diesel engine. The three-dimension combustion model of super-high pressure common rail system was constructed on the AVL Fire software platform. The numerical simulation of the fuel atomization and combustion process at standard load condition was completed. The results showed that the fuel injection law could become more flexible by regulating the super-high pressure common rail system; The whole heat release and power capability of super-high pressure common rail system is larger; The quantity of NOx, soot and fuel consumption rate of traditional pressure common rail system is higher; The super-high pressure injection shows more superiority and potential than tradition high pressure injection on combustion and emission characteristic.
