Camshaft

Camshaft is a shaft to which a cam is fastened or of which a cam forms an integral part.In a four-stroke engine, the valves are opened only half as often; thus, two full rotations of the crankshaft occur for each rotation of the camshaft. The timing of the camshaft can be advanced to produce better low RPM torque, or retarded for better high RPM power

Description

  • The camshaft is a mechanical component of an internal combustion engine. It opens and closes the inlet and exhaust valves of the engine at the right time, with the exact stroke and in a precisely defined sequence. The camshaft is driven by the crankshaft by way of gearwheels, a toothed belt or a timing chain.
  • The camshaft makes up an integral part of a vehicle. Three main parts make up a camshaft: the main journals, the lobes and the ends. Cam bearings are another important part of a camshaft. A valuable part of the engine, a camshaft helps the engine rotate.
