摘　　要：The two development ways of turbocharger technology to solve the problem of matching performance with diesel were presented. The ways of waste valve gate turbocharger and variable geometry turbocharger can solve the problem of engine’s low speed torque and achieve lower smoke level. Especially for variable geometry turbocharger, it covers all conditions of engine. It can not only improve the low engine’s speed torque and keep the power performance at high engine speed, but also cover wide engine speed performance that keeps lower fuel consumption and exhaust gas temperature in full load and part load matching. The results of theory analysis and experiment research showed that it’s the ideal solution to solve the matching problem of diesel engines.研究了改善涡轮增压柴油机匹配性能的两种方法 ,即废气放气阀方案和可变几何涡轮增压器方案 .这两种方案是目前改善柴油机的低速匹配特性 ,降低排放的主要措施 .特别是可变几何涡轮增压器能覆盖柴油机的整个工作范围 ,在全负荷和部分负荷下 ,既能增加低速转矩 ,又能保证高速功率不受到损失 ,还对降低油耗和排气温度有好处 ,经过原型机与这两种方案的理论研究及试验对比分析 ,证明了它是目前解决柴油机匹配特性的一种理想方法 .
