Heat losses in Ceramic Coated Diesel Engine

Abstract

The energy produced due to combustion of fuel in an engine is partly converted into work and the rest is lost. The knowledge of how the energy is lost will help in finding means to reduce the same to improve the performance of the engine in terms of efficiency and power output. The elimination of, in cylinder heat transfer to either the coolant or the environment does not violet the second law of the thermodynamics and moreover according to the first law, has the potential of producing more work. Another advantage of this concept is that great reduction losses in parasitic losses due to the simplicity of the cooling system, thus increasing the brake power of the engine. The main purposes of the study are to calculate the heat losses at different engine loads and speeds with and without ceramic coated diesel engine. The result showed a reduction in heat losses to the coolant and increases in exhaust energy at all the loads levels.
