摘要
介绍了吉利4D20轿车柴油机开发所应用的电控高压共轨喷油系统、冷却式废气再循环、尾气后处理装置、带VNT的涡轮增压中冷及可变进气涡流控制等先进技术。对整机按照欧洲排放测试循环进行了台架试验。结果表明,由于采用了众多先进技术,4D20轿车柴油机最高功率达100kW,升功率达50kW/L,全负荷工况最低油耗仅为210g/(kW·h),最大扭矩为307N·m(1800r/min),最大扭矩时噪声为85dB(A),同时排放各项指标均低于欧V排放标准限值。
Some advanced technologies applied to Geely4D20 car diesel engine are introduced, e.g. electroniccontrol high-pressure common-rail injection system, EGR, tail gas after-treatment, turbo-charge and inter-cooling with VNT, variable intake swirl control, etc. The bench test of complete engine is performed according to European emission test cycle, the result shows that with many advanced technologies applied, the maximum power of the engine reaches 100kW, power per liter reaches 50kWFL, the minimum fuel consumption under full load condition is only 210g/(kW.h), peak torque reaches 307N.m (1800r/min), the noise level at the maximum torque is 85dB (A), meanwhile, the emission indices are lower than the limits of Euro V emission standard.
