What is the intake branch pipe of a car
The automobile intake branch pipe is an important part of the engine intake system, which is located between the throttle and the engine intake valve. The "manifold" in its name comes from the fact that the air entering the throttle "diverges" through the buffered airflow channels, corresponding to the number of cylinders in the engine, such as four in a four-cylinder engine. The main function of the intake branch pipe is to distribute the air and fuel mixture from the carburetor or throttle body to the cylinder intake port to ensure that the intake of each cylinder is reasonably and evenly distributed.
The design of inlet branch pipe has important influence on engine performance. In order to reduce the gas flow resistance and improve the intake capacity, the inner wall of the intake branch pipe should be smooth, and its length and curvature should be as consistent as possible to ensure that the combustion status of each cylinder is the same. Different types of engines also have different requirements for intake branches, for example, shorter manifolds are suitable for high RPM operation, while longer manifolds are suitable for low RPM operation.
The most common intake pipe material in modern vehicles is plastic, because plastic intake pipe is low cost, light weight, and can improve hot start performance, power and torque. However, plastic materials need to have high temperature resistance, high strength and chemical stability to adapt to the operating environment of the engine.
The main function of the automobile intake branch pipe is to evenly distribute the mixture of air and fuel to each cylinder to ensure that each cylinder can get the right amount of mixture, so as to maintain the normal operation of the engine and efficient combustion .
Working principle and design requirements of inlet branch pipe
The inlet branch pipe is located between the throttle valve and the engine inlet valve, and its design has a decisive influence on the engine inlet efficiency. Excellent inlet branch pipe design can ensure that the cylinder is filled with enough air and fuel gas mixture, improve the engine combustion efficiency, so that the power output is more powerful . In order to reduce airflow resistance and improve intake efficiency, the length of the internal flow channel of the intake branch pipe should be consistent, and the inner wall should be smooth .
Material and structure of inlet branch pipe
The intake branch pipe is usually made of materials such as cast iron or aluminum alloy, which can withstand the high temperature and high pressure environment during engine operation, while ensuring intake efficiency and durability of service . The intake branch pipe is connected to the carburetor by a flange, secured to the cylinder block or head by a stud, and asbestos gaskets are installed at the joint surface to prevent gas leakage .
The relationship between intake branch pipe and exhaust system
The intake branch pipe is closely related to the exhaust system. The main responsibility of the exhaust system is to collect the exhaust gas after the combustion of each cylinder, and guide it to the exhaust pipe and muffler, and finally discharge to the outside atmosphere. The collaboration of the intake branch pipe and exhaust manifold ensures smooth exhaust gas discharge, reducing the exhaust resistance and heat load of the engine .
