Before we get to the intake manifold, let's think about how the air gets into the engine. In the engine overview we have mentioned that the piston in the cylinder operation, when the engine is in the intake stroke, the piston movement down to create a vacuum in the cylinder (that is, reduce the pressure), with the outside air pressure, so that air can enter the cylinder. For example, you should have had an injection, and have seen how the nurse inhaled the medicine into the needle bucket! If the needle barrel is the engine, then when the piston in the needle barrel is drawn out, the potion will be sucked into the needle barrel, which is how the engine draws air into the cylinder.
Due to the low temperature at the inlet end, composite materials begin to become a popular intake manifold material. Their light weight, with smooth interior, can effectively reduce the resistance and increase the efficiency of the intake.
