由于涡轮增压能提高发动机效率,从而可减少排放,因而它先是在轿车柴油机上,近年来又在小型汽油机上取得显著的市场增长。多涡轮增压、可变几何截面、废气旁通阀、废气旁通入进气歧管,以及发动机管理系统的联合应用,伴随着拥挤的发动机舱内较高的工作温度(汽油机超过1 000℃),这些都对从事动力总成、发动机舱内布置和标定的工程师们提出了严峻的挑战。 Since turbocharging can increase engine efficiency, which can reduce emissions, it first achieved significant market growth in sedan diesel engines and small gasoline engines in recent years. Multi-turbocharging, variable geometry cross-section, wastegate, wastegate bypass and engine management systems are combined with higher operating temperatures in the crowded engine compartment (petrol engines exceeding 1 000 ° C ) All pose serious challenges to engineers engaged in powertrain, engine room layout and calibration.
