摘　　要：设计了自动变进排气供油正时 (AVIEIT)系统的原理性验证试验方案 ,按此方案进行了相应的试验 .试验结果证实了 AVIEIT系统的思想 ,对原来采用高速工况放废气系统的车用柴油机来说 ,当采用 AVIEIT系统之后 ,在最大转矩工况点的性能基本不受影响 ,而在标定工况点时的有效油耗率可以降低 6 g/(k W·h) ,实验结果表明 。A scheme of testifying experiment of theory of automatic variable inlet exhaust injection timing system was designed. The corresponding experiment was carried out. The experiment results testify the idea of AVIEIT system. For the vehicle diesel engine which originally used Waste Gate system at a high speed work condition, after using AVIEIT system, the engine performance does not change at the maximum torque work condition, while the brake specific fuel consumption can decrease by 6 g/(kW·h) at the rated work condition. From the experiment results, it is concluded that Waste Gate system can be replaced by AVIEIT system.
