China Naming Network - Eight-character Q&A - Engine intake manifold

Engine intake manifold

In addition to the most basic metabolism, there will be air exchange inside the human body. Intake manifold is literally designed for intake air. Manifold means to send intake air to each cylinder separately and divide it into several branches through development and change. Figuratively speaking, it is the trunk. The water absorbed by the root system passes through the trunk and then through the branches to the leaves for photosynthesis. Some branches are like the air intake pipe of a car. Let's take a look at the intake manifold of the engine with the car editor of this station.

Engine intake manifold &; Introduction to mdash & ampmdash

The function of intake manifold is to distribute the combustible mixture provided by carburetor to each cylinder. The function of the exhaust manifold is to collect the exhaust gas discharged from each cylinder, send it to the exhaust pipe and muffler, and then discharge it to the atmosphere. The intake and exhaust manifold is usually made of cast iron, and the intake manifold is also made of aluminum alloy, which can be cast integrally or separately. The intake manifold and exhaust manifold are basically bolted to the cylinder block or cylinder head, and asbestos gaskets are installed on the joint surface to prevent air leakage. The intake manifold is equipped with a carburetor with flange, and the exhaust manifold communicates with the exhaust pipe downward. At present, there are six intake pipes in Jiefang CA6 120Q engine and Dongfeng E6 100Q engine, and the intake pipes are arranged in a rake pattern (streamlined, with low intake resistance), so that each cylinder can take gas independently, which is also conducive to improving the distribution uniformity.

Engine intake manifold &; Mdash & ampMdash intake pipe position

The intake manifold is related to the exhaust manifold, which is basically a component of the engine. Because of the low temperature, the intake manifold is basically black plastic to save costs, and the exhaust manifold is basically metal because of the high exhaust temperature. As for the position, you can see when you open the engine cover. For example, a four-cylinder engine is divided into four small tubes, and a thick black plastic tube is connected to the throttle of the engine at the end. Because the temperature is low, it is placed on the top outside, and the exhaust manifold is covered by the test because of the high temperature, so it cannot be touched.

Engine intake manifold &; Mdash & ampMdash Differences among Air Inlet, Air Inlet and Air Inlet

The intake pipe refers to the section of pipe where air enters from the air inlet, passes through the air filter and needs to enter the front of each cylinder. It is the key and universal intake pipe of the engine. The air intake is the passage through which air enters the engine block and leads to the cylinder. The key consists of a passage designed on the cylinder head, and the inlet at the end is an intake valve for regulating air intake. The intake manifold refers to the pipe through which air enters each cylinder from the intake pipe and distributes the air to each cylinder. Each cylinder has an intake manifold. The design of intake manifold ensures the reasonable and uniform intake distribution of each cylinder.
