The engine is undeniably one of the most important parts of every vehicle. Without it, your car cannot move. But engines alone cannot perform its task efficiently. That is why engines are equipped with a number of systems that help it do its job of converting fuel into motion. An intake manifold of inlet manifold is one part of an engine that plays a very crucial role. A car?s engine requires the right mixture of air and fuel to work efficiently. If this is attained, your engine would run very well. But still, without the intake manifold, your engine is of no use.

An intake manifold is a system of passages that carry out the fuel/air mixture from the carburetor to the intake valves of the engine. It is located between the carburetor and the cylinder head or cylinder heads on a late-model vehicle. The L-head engine?s manifold is mounted to the side of the block and the I-head manifold is mounted to the cylinder head. On age cars, a carburetor sits on top of the intake manifold and sends both air and fuel to the cylinder head. On multi-point injected engines, the intake manifold holds the fuel injectors.

Intake manifold design has much to do with the adept operation of an engine. For smooth and even operation, the fuel charge taken into each of the cylinder should be of the same strength and quality. Therefore, distribution of the fuel should be as even as possible. This depends greatly upon the design of the intake manifold. Dry fuel vapor is a perfect form of fuel charge; however present-day fuel avoids this unless the mixture is subjected to high temperature. If the fuel charge is heated extremely, the power of the engine is abridged because the heat expands the fuel charge. So, it is better to have some of the fuel deposited on the walls of the cylinders and manifold vents. Manifolds in modern engines are designed like this so that the amount of fuel condensing on the intake manifold walls is reduced to a minimum.

There will come a time that your engine would run poorly and perhaps you might wonder, what could be wrong? Age and intake manifold leaks are two major contributors to this condition. Intake manifold failures, particularly those with leaks may result to poor engine performance, engine overheating, or worst, severe engine damage. So, before this thing take place, regular maintenance should be done. It just takes minutes to check every part of your engine system.
