Suction pipe: role, work, change

The intake manifold is also called the intake manifold. The manifold is designed to supply air to the cylinders necessary for fuel combustion. The inlet pipe plays primarily a transport role. Thus, it forms a connection between the carburetor and the combustion chamber.

⚙️ What is inlet pipe?

We have to differentiate the intake pipe of a car from the one used on motorcycles or scooters. For a car, we usually talk about intake manifold than the inlet. This is the part of the pipeline equipped with valves that open and close.

Therefore they regulate the air supply to the combustion chamber depending on engine speed. The intake pipe connects the air filter or compressor and the engine cylinder head. Its role is to distribute air in the cylinders to ensure fuel combustion.

Thus, the intake pipe allows for partial provision of the combustion required for engine operation by providing the necessary air-fuel mixture. It forms the joint between the carburetor and the combustion chamber.

This means that in the event of a malfunction in the suction pipe, you may be faced with:

• of consumption problems fuel;
• of power losses motor;
• of Wedges repeats.

There may also be leaks in the inlet pipe seal. You will experience difficulty accelerating, loss of power and engine overheating, and coolant leaks. Then it is necessary to replace the gaskets to restore the tightness of the intake pipe.

For bikers, the definition of an intake pipe generally remains the same. This is the smaller part that transfers the air / fuel mixture from the carburetor to the engine... The intake pipe of a motorcycle can play an important role in the performance of a vehicle.

💧 How to clean the inlet pipe?

The inlet pipe can get dirty. Thus, sufficient fuel no longer reaches the engine and combustion deteriorates, which affects the performance of the vehicle. Then the suction pipe must be cleaned by dismantling or descaling.

Material:

• Tools
• Product stripping
• High pressure cleaner

Step 1. Remove the suction pipe [⚓ anchor "step1"]

To access the intake pipe, you must first access it. Remove the plastic cover located above the manifold. Disassemble EGR valve и Butterfly body by unscrewing the screws of the inlet housing. Finally, remove the intake pipe.

Step 2: clean the intake pipe

Can clean the intake pipe high pressure as soon as it is disassembled. This is necessary to remove all residues that have accumulated on the intake pipe: this is called calamine, soot residues from engine combustion.

Then apply a stripper to the inlet pipe and let it run for a few minutes. Rinse with clean water and dry.

Step 3. Assemble the inlet pipe.

Before reassembling the suction pipe, change print which has probably been damaged or worn out. This will ensure complete water resistance. Then you can reassemble the inlet pipe and then remove other parts. in the reverse order of disassembly... Make sure your air intake is working properly by starting the engine.

👨‍🔧 How to change the inlet pipe?

The intake pipe of the car does not wear out and has no periodicity. In other words, it doesn't need to be changed for the lifetime of your car, unless it detects a problem, of course. Replacing the inlet pipe is long and complicated operation.

Indeed, other parts must be disassembled to access them, which takes several hours. Therefore, the cost of replacing the intake pipe is high: qty. from 300 to more than 800 € depending on the car model. This interference should be left to the discretion of the professional.

On the other hand, it is much easier to access and replace the motorcycle intake pipe. First you need to disassemble the carburetor and fuel hose and then remove the intake pipe. Then you can replace it and reinstall it with the carburetor.

That's all, you know everything about the intake pipe! Hence, it is an important part of your engine that participates in combustion, allowing your car to move forward. If you are faced with a malfunction of the intake manifold or a leak at the level of its seal, take the car to a trusted mechanic as soon as possible!
