Four Cylinder Four stroke SI Engine

Abstract

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.
