A single cylinder four-stroke oil cooled Compression Ignition (C.I) engine is modified to use methanol fuel mode to study the performance, emissions, and exhaust gas temperature parameters on aluminium oxide (Al2O3) coated heater Surface Ignition Engine (SIE). In order to improve the performance at varying loads, the heating unit is introduced inside the combustion chamber. The brake thermal efficiency is improved by 1.5% in the heater assisted dual fuel +5% of agricultural waste coconut oil mode, and the top of the engine block is grinding to reduce half of the total clearance volume of the engine cylinder and increasing compression ratio (CR) (+1) on the existing CR 24+/-1:1 of the engine. The ratio of tested biofuel blends of Diesel (D) Methanol (M) and, agricultural waste Coconut oil (C) are D85%M10%C05%, D75%M20%C05% and, D70%M25%C05%. The ignition improver n-butanol is added with each fuel blends to uniformly mix the methanol with diesel and agricultural waste coconut oil. The relevant parameters such as brake thermal efficiency, brake specific fuel consumption, exhaust gas temperature, emissions of Carbon Monoxide (CO), Hydro Carbon (HC), Nitrogen Oxide (NOx), and smoke density are evaluated at the speed of 1250rpm. The reduction of brake specific fuel consumption, emissions and increase of break thermal efficiency are given for the D70%M25%C05 fuel blend.
