A Review of Design & Fabrication of Automatic Engine Valve Lapping Machine

Abstract

The engine valve lapping process is done to remove the excess carbon content from the valve and that of the seat of the valve. Due to the carbon content, the irregularities are formed between the seat and the on the valve and it causes leakage of the air-fuel mixture during the compression process and hence the efficiency of the engine is reduced. Hence the lapping process is carried out on the engine valve to remove the irregularities formed and provide it a smooth finish. The engine valve lapping machine is best for reducing the human effort and it consumes min. Time. The lapping machine is an automated system without any human interferes.
