The camshaft is an apparatus used in piston engines to operate poppet valves. It consists of a cylindrical rod running the length of the cylinder bank with
a number of oblong lobes or cams protruding from it, one for each valve. The cams force the valves open by pressing on the valve, or on some intermediate mechanism,
A series of camshaft:
In order to make you engine to keep good function, for reducing fueling depletion.
Once there is circumstance as following, you must replace old camshaft.
1. The camshaft aged.
3. The engine turns over.
4. The pollution is increasing.
5. The performance of engine is reducing.
The camshaft usually is used in the four angles of engine.
It mostly is used for controlling valve, and it also can drive other Equipment.
There is possible reason which affect performance of the camshaft and hydraulic tappet as following:
1. Material is incompatible.
2. Crudely made.
3. The surface is out-of-flatness.
4. The pressure of surface is asymmetry.
5. The shape is unqualified.
6. Don’t use the machinery oil commended by the manufacturer.
7. And about lube.
