摘　　要：发动机通过增压后可以显著提升其功率,在相同的功率下降低燃油消耗率。与此同时,也会导致进气温度偏高、发动机爆燃等问题。为了解决这些问题,通常会通过匹配中冷器,使增压后温度降低到发动机可以接受范围。本文主要介绍了某轻型客车开发过程中的中冷器匹配计算方法,并通过试验验证计算的准确性和可靠性,为后续中冷器的匹配开发提供技术参考。The power of the engine can be significantly improved by pressurization,and the fuel consumption can be reducedat the same power.At the same time,it will lead to high intake temperature,engine deflagration and other issues.In order tosolve these problems,usually by matching the intercooler,so that the temperature after the booster to the engine can beaccepted.This paper mainly introduces the calculation method of the intercooler in the development process of a light bus,and verifies the accuracy and reliability of the calculation through the experiment.This method provides technical referencefor the future development of intercooler.
