3938163 CUMMINS CAMSHAFT ¨C ISC
The Camshaft (part number 3938163) is a crucial component of an internal combustion engine. It is responsible for opening and closing the valves that allow air and fuel to enter the engine and exhaust gases to exit. Typically located in the engine block, the camshaft is driven by the crankshaft through a timing belt or chain. As the camshaft rotates, its lobes push on rocker arms, which in turn actuate the valves. The shape of the camshaft’s lobes determines how long and how far each valve opens, affecting the amount of air and fuel entering the cylinder and the efficiency of exhaust gas removal. Camshafts are often designed with different profiles for various applications, such as high performance or fuel efficiency. Proper maintenance of this component is essential to ensure optimal engine performance.
