An Analysis of Energy Flow in Diesel Engine on AVL-Boost
Main Article Content
Abstract
Energy achieved by burning fuel in an internal combustion engine (ICE) is divided into several main parts such as useful power, heat transfer for coolant system, energy of exhaust gases and mechanical losses. A detailed analysis of the quantity and distribution of these components will be an essential basis in the study of ICE improvement. In this paper, the authors present the calculation of energy distribution on D243 diesel engine through simulation on AVL-Boost. The results showed that the average thermal efficiency of the ICE during all operating modes was 25.8%. The total energy transfer for the coolant system and the heat of exhaust gases is 63.54% and reaches maximum 103.7 kW in rated mode. The acquired results can be used as a research basis to improve the economics and technical aspects of ICE such as optimization of working conditions of coolant and lubricating systems. As well as calculate the equipment of turbocharger or systems that utilize energy of exhaust gases and cooling water.
