Experimental Analysis of Valve and Valve Seats Wear in Gases (CNG) Fuelled Engine

Abstract

When CNG, LPG, and other gas fuels were used for combustion in vehicles' engines, a large degree of valve seat wear was observed and it was difficult to provide the same wear resistance as that of petrol (gasoline) & Diesel fuel engines. Therefore, valve seat wears in gas fuel engines need to examine. These parts related to the engine valve timing. Now the most of the company in engine manufacturing, found field related problem of valve and valve seat in gas engine. So most observed problem is valve and valve seat wear. In R&D department, durability is one of the ways to find the problem of valve and valve seat before the field related problem will face. In durability, the engine is test at approximately condition that of the vehicle, in engine test bed. So this paper gives material as per various parameters like Temperature. Mach inability, weld ability, Cost, availability is studied for valve & valve seat in gas fuel engine
