Investigation upon the operational factors influencing the smoke emissions from diesel engine

Abstract

Abstract The results of laboratory examinations of the ecological characteristics of diesel internal-combustion engine are represented in this article. The powerful, economical and ecological parameters of a diesel engine investigated in this article are presented by the speed characteristics of effective torque, injected fuel per cycle, and fuel and air consumption per hour, temperature, and smoke emissions of exhaust gases. On the basis of the experimental dependences a mathematical model is designed. Parameters influencing significantly the smoke emissions of exhaust gases are investigated. The factors, injected fuel per cycle and excess-air factor, are examined at different operation regimes of the engine.
