The ignition delay and engine exhaust emissions in a biogas-fueled diesel engine can be minimized by using a fuel with a high cetane number and high dissolved oxygen content. In this respect, diethyl ether (DEE) emerges as a promising additive, as it can be produced from ethanol at an acceptable cost and is renewable in nature. The high volatility of DEE prevents vapor lock in the fuel injection line. In dual-fuel operation, DEE can be introduced into the air intake port or fumigated with the biogas supply line to improve efficiency and reduce emissions. Studies show that DEE use in diesel engines operated in dual-fuel mode—with biodiesel or diesel as pilot fuels and biogas as the primary fuel—results in shorter ignition delay, reduced combustion duration, and increased peak cylinder pressure and heat release rate. Improvements in part-load performance and brake thermal efficiency (BTE) are also observed. Furthermore, DEE reduces hydrocarbon (HC), carbon monoxide (CO), and smoke emissions, though it may lead to an increase in nitrogen oxide (NO) emissions. Overall, DEE offers a viable pathway for enhancing the performance and environmental profile of biogas-fueled diesel engines.
