Performance, Emission and Exergy Analysis of Diesel Engine for Varying Engine Coolant Temperatures

Abstract: Only one third of the total fuel energy supplied to the conventional IC engine is converted to useful work, whereas a major part of the energy input is rejected to the exhaust gas and the cooling system. The idea of a low heat rejection (LHR) engine also called ‘‘adiabatic engine” was introduced in its potential for improving engine thermal efficiency by reducing the heat losses. In this study, the LHR operating condition is implemented by increasing the engine coolant temperature (ECT). Experimentally, the engine is operated at varying ECTs of 25°C, 50° C, 70° C and 90ᴼ C in an effort to get trend-wise behavior without exceeding safe ECTs. And performance, emission and exergy analysis were conducted on the engine. The study uses a single cylinder Mitsubishi Kubota diesel engine operating at 1500 rpm to examine the cases having different ECTs. The study revealed that increasing ECT yields improvements in performance and emission characteristics of the engine while an increase in NOx emission was observed.
