Combustion and Emission Behaviour of Honge Biofuel in a Thermal Barrier Coated Diesel Engine Suitable for Agriculture
Vehicular air pollution causes a huge threat to mankind, especially diesel engines. This study focuses on estimating the pollutant levels of Honge biodiesel in a single-cylinder IC engine which would be ideally suitable for agricultural field. The engine combustion chamber was coated with thin film ceramic material YSZ of 150 μm thickness using plasma spray technique and fuel injection pressure was varied. Honge blend B15 at 230 bar exhibited earlier heat release rate at 4°CA BTDC than diesel in coated engine. Emission reduction of CO, HC and smoke of about 50, 26.5 and 20% was attained for blend B15 compared with diesel and other biodiesel blends at 230 bar. NOx and CO2 emissions were high for Honge biodiesel fuels.
