Every vehicle has an intake manifold, which serves a vital engine function. It is sometimes called an inlet manifold and it is the part of the engine that supplies the air/fuel mixture to the cylinders and pistons. It is very important for the manifold to supply just the right amount of the combustible mixture to the different intake ports in the cylinder head. It then distributes the mixture evenly to allow the engine to run at optimal efficiency and perform in the correct manner. In some engines the intake manifold can also serve as a mount or housing for the throttle body and fuel injectors in the engine. Most intake manifolds are manufactured out of aluminium or cast iron but the use of composite materials is gaining popularity.
The design of the manifold and its orientation has a major effect on the efficiency of the engine. Major contours and angles create pressure drops within the manifold and reduce the efficiency of the engine. High-performance manifolds have smooth contours, allowing for better dispersion and improved engine performance. Modern manifolds usually have individual tubes that extend to the intake port of the cylinder head.
Call it the heartbeat of the vehicle – the intake manifold ensures that the vehicle operates and runs exactly as it should with the correct air and fuel mixtures being fed to the motor. These manifolds can be purchased at most spares stores. The intake manifold can malfunction or develop cracks through expansion and contraction due to heat in the engine. By simply offering the salesperson the correct year model of your car, they will be able to ascertain the correct intake manifold for your vehicle.
