Abstract


A comprehensive study on the methanol with three coatings has been carried out. A four stroke single cylinder diesel engine was adopted for the experiment. The present study aims to evaluate performance and emission level of methanol fuel with three types of ceramic coatings. In this study, the diesel engine was tested using methanol coated with three types of coatings namely copper, aluminium oxide, chromium oxide respectively. The performance of the engine coated is compared to the performance of engine with methanol fuel. The coating that produced the lowest exhaust temperature was at methanol fuel. The exhaust temperature for copper coating was higher compared to aluminium oxide coating and chromium oxide coating. The brake thermal efficiency for the three coating was not varying significantly but the highest was for copper coated. It was noticed that brake thermal efficiency was thus improved in almost all operation conditions with the methanol fuels. The HC and CO emissions are higher at methanol fuelled with copper coatings. NOx and smoke emission are lower for chromium oxide coating compared to Copper coating and Aluminium oxide coating. Among all coatings, copper coating exhibits better efficiency and lower emission compared to other coatings.
