What are the functions of the four tubes on the throttle of the 6th generation Camry?

1. One is the intake pipe, which connects the throttle valve and the air filter to filter out impurities and dust in the air entering the engine and ensure the normal operation of the engine.

2. One pipe is the intake manifold, and the pipes connecting multiple intake pipes can make the air flow smoother.

3. The pipeline is the air conditioner, which can adjust the amount of air entering the engine.

4. One pipe is an evaporation pipe, which connects the fuel tank and the engine to ensure fuel economy and environmental protection.
