Study on the Effect of Technological Change of Turbocharger on Vehicle Emissions and Engine Performance

Abstract

As important parts of the engine system, turbochargers can produce great influence on exhaust emissions for light vehicles. In this paper, we performed type I tests based on GB18352.5-2013 and engine performance test based on GB/T18297-2001.We analyzed the data of pollutants and engine performance from the same models with different manufacturing process of the turbocharger and proved that the manufacturing process change has no obvious influence on both engines and vehicles.
