For the purpose of reducing exhaust emissions of heavy-duty diesel engines, authors made an experimental study of diesel combustion by using a single-cylinder test engine. The engine performance and exhaust emissions have been measured by broad and high EGR ratio under the conditions of high boosting. The test engine adapted an independent supercharger, which raised the boost pressure up to 500 kPa, and EGR system was able to increase EGR ratio up to 40% under the 450 kPa boost condition. Various load and engine speeds were tested and the NOx has been reduced drastically without increasing PM (Particulate Matter).
