“…It is needed to durable engine parts to resist higher temperatures caused by TBC. On the other hand, the increase in NOx emissions is high due to such high combustion temperatures in the TBC engine (Hazar, 2010;Reddy et al, 2021;Aydın, 2013). It is possible to reduce NOx emissions by using the internal exhaust gas recirculation (Shabir et al, 2014) or alternative fuels (Özer et al, 2021).…”

Combustion stability in diesel engines is defined by cycle-to-cycle variations. In this study, effects of piston coating and engine load on cycle-to-cycle combustion behavior were investigated in a diesel engine operated on gaseous fuel mixture at different loads. Coated and uncoated piston tests under dual-fuel and single diesel modes were performed at three different loads including 50 Nm, 75 Nm, and 100 Nm at a constant speed of 1750 rpm. The piston bowls were coated by %8 yttria stabilized zirconia with the thickness of 0.4 mm. Dual-fuel mode is consisted of mixture of hydrogen enriched synthetic biogas, with the percentage of 80% CH4, 10% CO2, and 10% H2. Main combustion parameters (cylinder pressure with crank angle, peak cylinder pressure (CPmax), peak pressure rise rate (PRRmax), indicated mean effective pressure (IMEP), CA10, CA50, CA90, and CA10-90 duration) were addressed in view of cyclic aspects. The results showed that the piston coating was comparatively more effective in reducing the coefficient of variation (COV) and standard deviation (SD) values of main combustion parameters, especially at low and medium loads. SD, frequency distribution, and COVs of CPmax and IMEP were quite better at a medium test load of 75 Nm. The piston coating also reduced COV of CP with crank angle under all tests. As increasing the engine load, cyclic samples of CPmax and PRRmax enhanced and advanced for both diesel and dual-fuel modes. By the piston coating and engine loads, Cyclic CA10 and CA50 variations were slightly affected whereas cyclic CA90 were tremendously changed. Therefore, CA10-90 period was importantly affected by piston coating and load. The highest relationship among the main combustion parameters was between CPmax and PRRmax for both piston cases. In dual-fuel mode, a strong relationship emerged between IMEP and CPmax at low load.

“…Which lowers the generated power in engine and the performance. The temperature will be maintained in the combustion chamber to required level, unburnt gases will be burned which will reduce the polluted exhaust because of a decrease in heat loss in the piston [4,5]. In TB coating a bond coat and a top coat will be casted on piston.…”
