An Experimental Investigation of Engine Noise and Exhaust Smoke on a Small DI Diesel 911255

There are only few studies which address specifically to noise of small engines, and still fewer to noise and smoke both. In this paper Noise-Smoke-Fuel economy correlation study for a small DI diesel has been attempted. The effects of load, speed and injection timing on these parameters are discussed. A common basis for study of Noise and Smoke generation in a diesel engine has been presented. A definite correlation between combustion index with noise and smoke is obtained.
