Abstract: India is among those tropical countries where atmospheric temperature is having very vast range i.e. from 0°C to 48°C in various regions of the country. This vast varying temperature range may not allow the engine to perform uniformly, therefore, which temperature is most suited for operating parameters of engines and will give the best performance levels. The aim of this study is to analyze the performance of a compression ignition (CI) engine using Jatropha biodiesel and its blends with diesel as fuel on changing engine temperature to obtain best performance levels. It has been tried to investigate the optimum operating temperature of engine that will deliver the best performance level. The blends of Jatropha with diesel in varying proportions (B10, B20 and B40) are prepared and are investigated in single cylinder, four stroke CI engine computerized test rig. The results obtained on engine performance parameters i.e brake power (bp), brake specific fuel consumption (bsfc) and smoke i

Abstract: Valves used in passenger car engines, running on gasoline, operate in a very hostile environment that is characterized by high temperatures and pressures, impact loading, thermal stresses, and fatigue loading. These engines, when in operation, result in generation of temperatures that are close to 600ºC inside the intake valve; the corresponding value for the exhaust valve being 700°C to 800°C, respectively. However, the exhaust valve temperatures can shoot up to 950°C for a retrofitted LPG – run gasoline engine. Engine valves, being subjected to such high temperature and pressures, are extremely vulnerable against wear and consequent failure. Wear failure of valves is a commonly encountered phenomenon and the fatigue crack growth has its own role to play in contributing to the failure. The wear mechanisms in valves of LPG – run retrofitted engines have been found to be a combination of oxidation and adhesive wear, though valves also fail due to surface erosion and corrosion.
