Description

Intake pipe

The present invention provides an intake pipe, in particular, a first pipe body of a metal material and a second pipe body are connected by an elastic material adapter sleeve, and the compressed air output from the central cooler passes through the intake pipe to the engine. When the inner tube and the second tube body are made of metal, the structural damage can be avoided.

According to the rapid development of industrial and commercial economic activities, as well as the general improvement of the income and consumption capacity of national production, coupled with the busy and compact nature of the city, people in their daily lives are the best means of transportation by car, locomotive, etc. However, it is precisely because cars, locomotives and other vehicles are constantly increasing. The carbon dioxide and exhaust gas emitted from the operation of their engines have become one of the main sources of air pollution, and the impact of the overall environmental warming of the earth will also increase. Therefore, the manufacturers of various vehicles such as automobiles and locomotives are not actively investing in research and development to improve the combustion efficiency of engines, and introduce new environmentally-friendly vehicles that can reduce the carbon content of exhaust emissions of vehicles to reduce environmental pollution.

Due to the booming automotive engine technology in the market, the design of the automobile engine has entered the era of computer control, and the electronic control unit (ECU) is used to control the throttle valve installed in the intake manifold of the engine, so that the car can rely on the throttle Adjusting the intake air amount by stepping on the judgment or accelerating to obtain the ideal air combustion ratio of the engine, and also meeting the exhaust standard set by the Environmental Protection Agency. In order to increase the output power of the engine under the same working efficiency, the fuel can only be increased by compressing more air into the engine cylinder to increase the combustion efficiency. Therefore, the turbocharger system is generally installed on the vehicle. In order to increase the intake air volume, the turbocharging system uses the exhaust gas discharged from the exhaust stroke of the engine to rotate the exhaust rotor of the turbine. When the exhaust rotor reaches a certain rotational speed, the intake rotor is coaxially driven to forcibly suck in additional air. However, as more air is compressed, the temperature will rise rapidly, and the oxygen content in the compressed air will decrease and the combustion efficiency will decrease. Therefore, a central cooler must be used to cool the air temperature so that the temperature of the intake air is centrally cooled. The temperature can be lowered after the device, and the lower the intake air temperature, the more the oxygen content will increase.

However, between the central cooler and the intake manifold of the engine or the throttle valve in the intake position of the intake manifold, an intake pipe is connected to connect the compressed air output from the central cooler through the intake pipe. The intake manifold enters into the engine cylinder for combustion, and the throttle valve cooperates to control the flow rate of the compressed air into the engine cylinder, thereby increasing the fuel amount and increasing the combustion efficiency in the engine cylinder, but the intake pipe is mostly made of plastic. Made of materials (such as acrylonitrile-butadiene-styrene copolymer, abbreviated as ABS), and often have a certain high temperature when compressed air passes through the intake pipe, making the plastic material of the intake pipe itself easy to encounter. The thermal expansion causes brittle fracture and the durability is not high. In addition, the flow rate of the compressed air passing through is very fast, which causes the airflow at the corner of the intake pipe to be strong, so that the intake pipe has insufficient pressure resistance to cause structural damage or damage, that is, The key to research and improvement for those who are still in the industry.
