Mercedes Benz Intake Manifold

How can the design of a stationary part affect the overall performance of a system? Well, get the idea from the Mercedes Benz intake manifold. The intake manifold may just be another stationary part of a Mercedes Benz’s air intake system, but its design can greatly affect the efficiency of the system. So important it is that even the Mercedes Benz engine won’t perform at its best if the intake manifold was designed poorly.

The intake manifold is the system of passages responsible for transporting the proper mixture of air and fuel from both the fuel delivery system and the intake system to the vehicle’s engine for combustion. For newer Mercedes Benz vehicles, the intake manifold would usually be positioned between the throttle body and the cylinder head(s) and would also usually hold the fuel injectors (for multi-point injected engines). For older vehicles, the intake manifold connects the carburetor and the cylinder head(s).

There are many types of intake manifold design, the two most popular of which are the single plane intake manifold and the dual plain intake manifold. These two manifolds have different configurations and while the dual plane manifold would work well on low RPM operations, the single plane manifold would work if the conditions are reversed. Nevertheless, both intake manifold designs transport the air and fuel mixture in the same manner, which is from the throttle body or carburetor into a chamber called plenum, and from there to individual tubes called runners down to the intake ports of each cylinder in the engine. But aside from plainly delivering the mixture to the engine, the intake manifold must also deliver in each of the cylinders a mixture of equal strength and quality.

As to how an intake manifold must be designed so that it would function at its best, maybe we’ll just leave that to the experts. But if you only want to see what a good intake manifold design is, just take a look at the inlet manifold that your Mercedes Benz is equipped with. If still new and in tip-top shape, it is guaranteed to function well. But if it is already old, corroded and has a lot of damages, you better replace it with a new unit if you still want the engine to function at its best.
