Abstract

The commonly used form of transportation would mostly rely on road vehicles nowadays. A vehicle is a mechanism used to commute between different places with higher efficiency and less time consumption. A vehicle would usually consist of multiple working components and the engine is well-known to be one of the most crucial components in it. Although it can be considered as the most vital components in a vehicle the gaps of knowledge for an engine is still unlimited. It can be said that there so much more potential that can be explored for an engine to reach its maximum capabilities. Part of the perspective that should be explored would be to study the engine^s thermal properties. This paper aims to access the effect of varying temperature at the exhaust manifold under certain amount of time spans. The temperature varied from low to high and vice versa for 6 cycles. From the simulations, it was discovered that the exhaust manifold had undergone an alteration in the strain of the body^s elasticity. Due to that the displacement of exhaust manifold, load distribution and its direction have also been affected.
