摘　　要：将CA488汽油机改装成天然气发动机,并匹配合理的可变截面增压系统,利用软件对改装后的发动机进行性能模拟。结果表明,对可调增压器进行合理的控制,可将改装后的天然气发动机动力性恢复到原机水平。A CA488 gasoline engine was refitted as a compressed natural gas (CNG) engine and matched with a proper variable geometry turbocharger (VGT). Performance simulations of the CNG engine system was carried out by taking advantage of some software. Simulation results show that the CNG engine can reach the same power output as the CA488 gasoline engine does if the variable geometry turbocharger system is controlled accurately.
