Where a single camshaft is used, known as a In this guide we’ll talk mainly about OHC arrangements because they are more direct and easily understood.įor OHC engines, there may be a single camshaft in an engine, or there may be one for the intake valves and one for the exhaust valves - this is the most common layout for modern engines, known as a There are advantages and disadvantages to both systems, but overhead cam engines are almost universal nowadays, with the exception of big V8 engines produced by Chevrolet. The valves are then driven by pushrods which act on rocker arms. (OHV) and in this layout the camshaft will be installed in the engine block, below the valves. Or OHC, the camshaft is above the valves. In the predominant engine design, known as There are two different arrangements in use that determine where the camshaft is placed in the engine. The pistons turn the crankshaft, which turns the camshaft, which controls the valves. The valves must therefore be synchronised with the pistons, and this happens by connecting the camshaft to the crankshaft using a timing belt, timing chain or system of gears. At all other times, the valves are closed. That is to say, on the intake stroke we want the intake valve to be open, and on the exhaust stroke the exhaust valve is open. The valves need to open open and close at the right moment in relation to the pistons. The camshaft is the most precisely engineered part of the entire car - it can be thought of as a mechanical computer program which tells each valve when to open, and how far to move when it does open. The cams push against the valves and the bulge in the cam will cause the valve to open. The valves and camshaft together make up theĪ camshaft is a rotating shaft that consists of a number of pear-shaped lobes, known as
