Where is the engine intake pipe?

The engine intake pipe is located between the throttle valve and the engine intake valve. The intake pipe is the main intake pipe, and the intake branch pipe distributes air to each cylinder to support combustion. The gas passes through the carburetor to atomize gasoline and enters the cylinder with the air. 

The engine intake duct is the passage for air to enter and exit the air purifier. The air purifier is connected to the carburetor through a pipe, and the intake branch pipe is connected to the bottom of the carburetor at the upper end and to the intake valve of the cylinder block through a pipe. The intake pipe includes the main intake pipe and the branch intake pipe. In addition to power requirements, the engine also needs to have good fuel efficiency and emission performance. 

In gasoline engines, the intake pipe must also consider issues such as combustion atomization, evaporation, distribution, and the utilization of pressure waves. On diesel engines, it is required that the airflow passes through the intake duct to form an intake vortex in the cylinder, in order to improve the formation and combustion of the mixture.
