The intake manifold can also help Bare Engine achieve normal idling operation. Idle refers to the working state of Bare Engine when the vehicle is stopped or driving at a very low speed. The intake manifold can ensure that Bare Engine maintain stable operation at idle speed by controlling the flow of air.

Now let's understand the principle of the intake manifold. The design of the intake manifold usually adopts the form of curves or broken lines to increase the flow rate and flow of air flow.

In addition, some special structures are also used inside the intake manifold, such as the variable diameter design of the intake duct, the branch design of the intake duct, etc., to optimize the flow and distribution of air.

For different types of Bare Engine, the design of the intake manifold will also be different. For example, for high-performance Bare Engine, the intake manifold usually adopts a shorter length and a larger diameter to increase the flow rate of air.

For low-power Bare Engine, the intake manifold usually adopts a longer length and a smaller diameter to increase the pressure in the intake manifold.

To sum up, it plays an important role in guiding and distributing air in the work of Toyota Engine. It not only introduces air into the combustion chamber of Bare Engine, but also improves the intake efficiency and power output of Bare Engine. The design and optimization of the intake manifold has a significant impact on the performance and fuel economy of Bare Engine.
