Abstract

Facing the problem of environmental pollution in big cities, car manufacturers worldwide have researched and developed cars with small engine capacity but still ensure the vehicle operates efficiently on highways. The company used a small gasoline engine equipped with a turbocharger system to achieve this. When the car runs in the city, the engine will operate with a small capacity to save fuel and reduce emissions. When the vehicle is used on the highway, the turbocharger system works to help the engine act like a large engine. However, when turbocharging causes engine temperature, the load bearing on the crankshaft mechanism and connecting rod will increase. Therefore, research on this issue is needed so the engine can operate stably and efficiently. In this study, the author goes into the calculation and testing of the crankshaft of the gasoline engine when turbocharged with a boost coefficient of 1.5. The results show that the equivalent stress acting on the gasoline engine crankshaft when turbocharging is 301.79 Mpa, satisfying the durability condition.
