Abstract :
The process of performance design and development for BF4M2012 engine is presented in this paper. The prototype model is based on an engine with 2 valves per cylinder and EUP system which peak injection pressure is 160MPa. With the help of the EGR system and POC after-treatment system, the combustion system is optimized with regard to turbocharger, EUP plug diameter, nozzle flow rate and holes number etc. After parameter calibrations of EGR rate and SOI with DOE method, the engine meets China IV emission regulation finally. GT-Power and Star-CD software are used to optimize turbocharger, combustion bowl and fuel nozzle.
