摘 要：In order to meet fuel consumption regulation China Phase 4 and emission regulation China 6,China FAW(First Automobile Work) developed a 1.4 L GDI miller *** cam profile and turbocharger were optimized and designed by one-dimensional thermodynamic analysis.A delicate design of high compression ratio,spray target,and intakeport was realized by Computational Fluid Dynamics(CFD) analysis of in-cylinder flow,atomization and *** combustion system was finally settled based on optical and thermodynamic engine with the primary target:the specific power is 79 kW/L,the specific torque is 168 N·m/L,the Brake Specific Fuel Consumption(BSFC) is 225 g/kW·h,the maximum thermal efficiency is 37.5%.
