Correlation of Exhaust Smoke to Significant Operation Variables in a Direct Injection Diesel Engine PDF

Abstract

In this study a simple quantitative correlation for predicting exhaust smoke level from a direct injection diesel engine has been developed. The effects or different engine operating parameters on exhaust smoke level have been investigated experimentally. The experimental results showed that exhaust smoke is significantly affected by changes in the diffusion burning fraction, engine speed and overall equivalent ratio. As a result a simple quantitative formula which relates exhaust smoke to these variables is presented.
