- Abstract
- The purpose of this work is an experimental investigation of combustion and emission characteristics in DI diesel engine applied high EGR rate as a method of low-temperature combustion. In order to analyze the effect of EGR rate variation, a single-cylinder DI diesel engine was operated under various EGR rate conditions. In addition, injection timing was variously controlled to investigate the effect of injection timing in DI diesel engine using the cooled-EGR system. The NOx emissions were decreased in accordance with the increase of EGR rate. On the contrary, soot emissions were generally increased under applied EGR conditions. However, soot emissions were decreased in a few injection timings under high EGR rate conditions. The EGR results show that the ignition delay were increased by decreased oxygen concentrations in combustion chamber under the high EGR rate.
