Impacts of Continuously Regenerating Trap Technology on the Regulated Gas Emissions for a China-V Diesel Engine

Abstract:

In this paper, the effects of continuously regenerating trap (CRT) after-treatment system on performance, fuel efficiency and regulated gas emissions from a turbocharged electronically controlled high pressure common rail diesel engine that meets China-V regulation have been investigated. The test results revealed that: the power and torque of diesel engine after the installation of CRT after-treatment system declines slightly, which is limited to 2%, and the rise in brake specific fuel consumption is around 2%. At the same time, the emission of CO decreased significantly by 86% to 94%, NOx also reduced slightly by 8% to 12%. However, the emission of HC dropped at part loads and rose at full load modes since the original engine emission is already quite low.
