Four Cylinder Four stroke SI Engine

Subramaniyan Raj, Rama iyer


The present paper deals with layout of cylinder & cylinder head with air cooling device for four strokes 4 cylinder SI engine .the main goal of design is to reduce weight to power ratio & will bring about generating excessive specific energy. The authors have proposed initial design cylinder & cylinder head of a horizontally adverse SI engine, which develops 120 BHP and posses the maximum rotational speed of 6000rpm. 4 stroke opposed engine is inherently well balanced due to opposite vicinity of shifting loads and also it presents efficient air cooling. For the necessity of weight diminishment the texture chosen for plan of barrel and chamber head is Aluminum compound that is LM-13. The chamber bore covering the utilization of NIKASIL covering changed into completed to enhance power of barrel with least weight.
