“…BSFC of bio-diesel fuelled engine increases and BTE reduces due to increase in the fuel consumption rate. It is possible to reduce the fuel consumption and heat losses to engine cooling system by coating the combustion chamber and piston crown surfaces with ceramic materials [2,3]. Ramadhas et al [4] used rubber seed oil and its diesel blends in a single cylinder diesel engine and observed that the blends containing 20-40% of rubber seed oil in the blend yielded similar engine performance with that of diesel.…”

“…As is seen, CO emission values of coated engine were lower than normal engine under all the brake power values. CO is an emission type which occurs as a result of incomplete combustion of fuel and is related to parameters such as incylinder temperature and air/fuel rate [7,11]. Since burn -out temperature and combustion chamber pressure increase in LHR engines, CO emission is expected to be lower.…”

“…It is thought the fact that burn-out temperature, which increased because of thermal insulation in coated engine, the gas temperature within the chamber and combustion wall temperature increased affected BSFC values positively [4]. In addition, it was considered that shorter ignition delay period in LHR engines affected chemical and physical delays positively, which caused BSFC values to decrease in LHR engines [7][8][9]. Figure 5 illustrates brake specific energy consumption changes of diesel engine at fixed rpm under different loads specific energy consumption measurement is an important parameter to compare brake thermal efficiency of engine.…”

In this study, adiabatic property was brought to a 4-cylinder natural aspirated, direct injection diesel engine. For this purpose, cylinder liner, piston upper surface and valves were coated with powder with boron. Solid-boronizing method and plasma spray method were used as coating method. While cylinder liner and valves were coated with the layer of Fe2B in the thickness of 150 micron by using solid boronizing method, piston upper surface was coated with the layer of CoNiCrAlYttra +NiCrBSi in the thickness of 300 micron by using plasma spray method. After the coating process, the engine was subject to performance and emission tests. ASTM-D-2 fuel was used as test fuel. As a result of tests, while BSFC value of coated engine decreased at the rate of 7.5% and BSEC value decreased at the rate of 7% and at the rate of 15% in EGT value. While a decrease was observed at the rate of 10% in CO value, 47% in HC value, and 14% in Smoke value, an increase was observed at the rate of 35% in NOx value.

“…Also, sunflower oil blends presented better performance and emission parameters than cottonseed oil blends. H. Hazar et al 8 studied the effect of Al2O3-TiO2 coating in a diesel engine on the performance and emission of corn oil methyl ester and compared the same with uncoated engines. A decrease in engine power and specific fuel consumption, as well as significant improvements in exhaust gas emissions (except NOx), were observed for all test fuels used in the coated engine compared with that of the uncoated engine.…”
