![]() Dual Intake ManifoldĪ well-designed manifold has the shortest and smoothest path from carburetor to cylinders. However, it sits between the two cylinder banks in V engines. Manufacturers mount the intake manifold on the cylinder head/block depending on its design. The carburetor sits on the inlet manifold. Manufacturers design the intake manifold in such a way that the air-fuel charge quickly reaches the engine cylinders. It carries the fresh charge from the carburetor to the intake valve ports. Manufacturers centrally mount the carburetor on the intake manifold. Some modern manifolds are even powder coated or chrome plated. The inlet/intake manifold consists of a cast iron or aluminum tube. Hence, there is a noticeable difference in the quality & quantity of the charge at low engine speeds. It is mainly because the intake manifold has different passage sizes, angles, contours, flow rates, temperatures, etc. However, in reality, the quality & quantity of the charge supplied varies for all the cylinders. Therefore, the system maintains the equal combustion chamber pressure only when it meets the above conditions. Correct ignition timing ensures the spark is fired at the right time to burn the charge completely. Each piston compresses the charge equally as per the compression ratio. Proper valve timing allows the supply of an equal amount of charge to the cylinders, according to the firing order. Intake manifold forwards and directs an equal amount of charge to cylinders. It mixes the fuel with the incoming air in correct proportions and supplies it to the engine. Single Flange Function:Ī carburetor feeds the charge or air-fuel mixture to the engine. So, manufacturers pay special attention while designing the engine intake manifold. Besides, the charge’s quality, physical properties, and air-fuel ratio must be precisely the same. It is achievable if the charge going into the cylinders is of the same quantity. The multiple combustion chambers must produce equal combustion pressure for the smooth operation of a multi-cylinder engine. It deals with vehicle performance, such as power and torque. The intake system is one of the most critical engine systems. ![]()
