“…Due to the reduced combustion efficiency, the engine needs to transfer more fuel to the combustion chamber to produce the same power and therefore causes an increase in BSFC values. The results of the study are similar to those in the literature [18][19][20]. When BSFC was compared between standard engine and Thermal barrier coated engines, it was found that there was a decrease of 2.85% in Cr2O3 coated engine, 7.47% in Cr2O3+50%Al2O3 coated engine and 11.57% in Cr2O3+75% Al2O3 coated engine.…”

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%.

“…The Zeldovich mechanism and the availability of oxygen undoubtedly influence the kinetics of O 2 production. The combustion temperature, which increases NOx generation, is another variable that aids in the interaction between N 2 and O 2 molecules [ 31 ]. There was an increase in NOx emissions for conventional engines operating at low speeds and for LHR engines operating at full load.…”

Climate change, clean air, renewable energy, nontoxic surroundings, and the opportunity to live in a healthy community are just few of the issues that environmental sustainability addresses. To improve environmental health and quality of life, several researchers have turned their attention to alternative energy sources like ethanol and oxyhydrogen. In latest years, significant progress has been made in the development of ethanol and hydrogen as clean energy sources. A higher octane rating is achieved by mixing ethanol with gasoline rather than using regular gasoline. A novel mix of oxyhydrogen, ethanol, and gasoline is ecologically friendly while simultaneously increasing the performance of gasoline engines. In this study, a nanoparticle-coated piston on a low heat rejection gasoline engine fuelled by an ethanol-gasoline mix with oxyhydrogen addition was investigated. It has been evaluated that thermal efficiency improved by up to 25% while fuel consumption can be reduced by up to 28% on a volume basis compared to the baseline engine. Furthermore, the decrease in harmful carbon monoxide reached around 10%, and the reduction in unburned hydrocarbon emissions reached 18%.

“…This means more useful work with the same amount of fuel. In general, the thermal barrier coated engines have less fuel consumption than the standard engine [24,25]. The reason for reduced brake specific fuel consumption values with the use of coated pistons is considered as a result of the increase in combustion temperature.…”

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%.
