“…As the engine speed in internal combustion rises, a rise in engine torque is seen. This increment passes through the maximum point and causes a decrease again [16]. In Figure 7 also, a decrease is seen after 2600 rpm, friction losses increase with the speed of the beating engine, the engine torque is decreased after 2600 rpm due to the decrease in the volumetric efficiency as the fuel-air mixture time gets shorter.…”

The piston and valve surfaces of diesel engine have been coated with Cr2O3, Cr2O3+50%Al2O3 and Cr2O3 + 75% Al2O3 ceramic powders with bond coat (NiCr) by atmosferic plasma spray (APS) method. The engine performance of the coated engine were compared with the standard engine values by using that the engines tests were applyed repeat for each specimen in an electrical dynamometer in full power 1400 rpm, 1700 rpm, 2000 rpm, 2300 rpm, 2600 rpm, 2900 rpm and 3200 rpm engine speeds. In the results; it has been seen that engine power increased from 7% to 29%, engine torque from 7% to 23%, and exhaust gas temperatures from 6% to 17%, thermal brake efficiencyfrom 2.8% to 12.7% while specific fuel consumption decreased of 2.8% to 11.5%.

“…As the engine speed increases in internal combustion engines, the increase in engine torque is seen, and this increase is seen again by passing a maximum point [22]. The increase in torque with increased engine speed, after 2600 rpm, is thought to reduce engine torque due to the increase in cylinder walls and gas temperatures resulting from the increase in volume efficiency and increased friction losses at high speeds as a result of thermal barrier coating.…”

In this study, piston and valve surfaces of a diesel engine to improve exhaust emission and engine performance values, NiCr with bond coat and without bond coat with Cr2O3, Al2O3+13%TiO2, Cr2O3+25%Al2O3 coatings were coated using plasma spray method. By examining the microstructures of the coating materials, it was observed that a good coating bond is formed. In this study, unlike other coating applications, two different and proportions of specific ceramic powders were coated on the combustion chamber elements, mounted on a diesel engine, and their effects on engine performance and emissions were tested on the engine dynamometer. For this purpose, the internal combustion engine was operated at 1400, 1700, 2000, 2300, 2600, 2900, and 3200 rpm engine speeds and engine power, engine torque, incylinder pressure changes and HRR values were recorded. In this study, the that results were obtained by comparing thermal barrier coated engine with standard engine. An increase of 14.92% in maximum engine power, 12.35% in engine torque, 13% in-cylinder pressure, heat release rate by 4.5% and brake thermal efficiency by 10.17% was detected, while brake specific fuel consumption decreased by 14.96%.
