An experimental investigation on ceramic coating with retarded injection timing on diesel engine using Karanja oil methyl ester

Abstract

Rising demand for fuel will now pose a major risk for global pollution levels in various applications. The biodiesel of Karanja oil methyl ester (KOME), an alternative to diesel fuel, is a potential source of unspent fuel in India. The goal of this experiment was to research low-heat rejection using Karanja oil methyl ester with retarded injection timing diesel-fuelled. With 0.5 mm thickness of partial stabilised zirconium (PSZ), the piston, cylinder walls and engine valves were coated without affecting the engine compression ratio. Experiments in the engine with and without coating were carried out using diesel or Karanja oil methyl ester. The results showed that the specific fuel consumption for Karanja oil methyl ester with a retarded timing-reduced engine decreased by 7.4% and the brake thermal efficiency improved by 5.5% compared to the conventional engine with nice diesel fuel.
