The correct answer is C: supply the fuel/air mixture to the cylinders.
1. The intake manifold is a crucial component in an internal combustion engine.
2. Its main function is to distribute the fuel/air mixture to the cylinders for combustion.
3. The intake manifold collects the air from the air filter and mixes it with fuel before delivering it to the cylinders.
4. This mixture is essential for the engine's operation, as it provides the necessary fuel and oxygen for combustion to occur efficiently.
5. By regulating and directing the flow of this mixture, the intake manifold plays a vital role in the engine's performance and power output.
In summary, the intake manifold's primary purpose is to supply the fuel/air mixture to the cylinders, enabling combustion and powering the engine.
