Investigation the Effect of Deposit Formation on Exhaust Valve and Lubricating Oil Debris Using Green Alcohol Blend Fuel in Spark Ignition Engine

Alcohols is a renewable fuel that might be used in place of fossil fuels. The economical development of each country is greatly impacted by its energy supply. The energy comes from fossil fuels, which are not renewable and have a negative impact on the environment. In this study, waste cooking oil and diesel fuel are compared as a binary combination. Engine testing is conducted with a continuous load at 1450 rpm. This study examined the effects of PF90E10 on engine exhaust valve deposits when ethanol blend fuel was injected during the endurance test in place of base gasoline. Visual examination of the study’s findings revealed that both gasoline samples had some deposit accumulation on their injectors. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) analysis showed that the engine using the PF90E10 produced larger carbon deposits on and around the valve surface. Furthermore, the PF90E10 binary combination may be used in a gasoline engine without any alterations. The SPL increased by 7.8 dB at engine speed in the case of the PF100. Nonetheless, the PF90E10 binary mix’s average SPL was 4.3 dB less than the baseline. Finally, without requiring any engine modifications, binary emulsion may be utilized in engines that use spark ignition. Consequently, E10 may be effectively utilized to lessen negative impacts and decrease reliance on fossil fuels. Furthermore, compared to the baseline, there was a lower concentration of lubrication oil debris cadmium (Cd).
