What is the temperature of the engine exhaust manifold?

1. The temperature of the engine excluded to the exhaust manifold is 800~900 degrees, and the temperature of the pre-stage ternary catalyst has decreased. The temperature of the tail silencer is around 150 degrees, and the exhaust gas cooled by the silencer partition is slightly higher than the normal temperature of 20~50 degrees.

2. Engine temperature: The temperature of the engine excluded to the exhaust manifold is 800-900 degrees. The temperature of the pre-stage ternary catalyst is 600-700 degrees. The temperature of the silencer interruption has decreased. Basically, it is 200-300 degrees. The temperature of the tail silencer is around 150 degrees. The exhaust gas from the cooling of the sound diaphragm is slightly higher than that of 20-50 degrees at normal temperature.

3. If there is no supercharger, the temperature of the outer wall of the main pipe is 180-350 degrees Celsius, and the temperature of the outer wall of the manifold is 90-150 degrees Celsius. With the motivation of the supercharger, the temperature of the outer wall of the main tube is 300-450 degrees Celsius, and the temperature of the outer wall of the manifold is 120-200 degrees Celsius. Under the high temperature in summer, the temperature may be higher due to poor heat dissipation.

4. The temperature of the car exhaust pipe is between 800-900 degrees, which is quite high. If there are hay, oil and other flammable substances under the parking space of the car, the high-temperature baking of the exhaust pipe will cause a fire, so be sure to pay attention to whether there are flammable materials around when parking.

What is the function of the intake and exhaust manifold?

The intake manifold and the exhaust manifold are connected in parallel, which can use the residual heat of the exhaust to heat the intake manifold. Especially in winter, steam is difficult to vaporize, and even atomized gasoline tends to condense. The rounded corner of the exhaust duct and the corner of the pipe are large, mainly to reduce the resistance and make the residual exhaust gas discharged as cleanly as possible.

The function of the intake manifold is to dispate the combustible mixture supplied by the carburetor to each cylinder. Put in orderThe function of the gas manifold is to collect the exhaust gas after the operation of each cylinder and send it to the exhaust pipe and silencer, and then discharge it into the atmosphere.

The parallel connection of the intake affiguity and the exhaust manifold can use the residual heat of the exhaust to heat the intake manifold. Especially in winter, the evaporation of Qishan is relatively difficult, and even the gasoline that has been atomized tends to condense. The rounded corner of the exhaust channel and the corner of the pipe are large, mainly to reduce the resistance and drain the residual gas as cleanly as possible.

What is the working principle of the exhaust manifold of the automobile engine?

1. Ternary catalysis, usually located behind the manifold assembly point, is used to filter the exhaust of each cylinder. The function of the silencer is to reduce noise. For domesticWhen the displacement and power of the car do not allow us to blow up the street, the silencer is very helpful for the comfort of driving.

2. The exhaust manifold is connected to the engine cylinder block, and the exhaust gas of each cylinder is concentrated and introduced into the exhaust manifold through different pipes. The key to its requirements is to minimize the exhaust resistance and prevent interference between cylinders.

3. The function and working principle of the intake manifold are as follows: the function of the intake manifold is to deliver the combustible mixture supplied by the carburetor to each cylinder.

What is the function of the intake manifold (what is the function of the exhaust manifold)? The function of the intake manifold is to distribute the air and fuel mixture from the carburetor or throttle body to the intake duct of each cylinder. For airway fuel injection engines or diesel engines, the intake manifold only distributes clean air to the intake duct of each cylinder.

Car air intakeThe function of the manifold: The function of the intake manifold is to distribute the combustible mixture provided by the carburetor to each cylinder.

The first part is the part connected to the engine cylinder head discharge port, which is called the exhaust manifold. After collecting the exhaust gas through the cylinder head discharge port, it can be discharged smoothly.

Will the failure of the exhaust manifold affect the power?

1. Yes. The damage of the rear end of the exhaust pipe means the damage of the non-catalytic part. If the ternary catalytic part of the rear section of the exhaust pipe of the car is damaged, the electronic control unit will detect it. At this time, ecu will limit the power output of the engine, so the damaged ternary catalysis will affect the power of the car.

2. If the base is deformed, it must be replaced. If the exhaust pipe is flat, it will affect the exhaust efficiency. The deformation displacement will interfere with other parts of the chassis and make a strange sound.

3. If the exhaust pipe of a car is broken, it will affect the engine power, and if the exhaust pipe of a motorcycle is broken, it will not affect the engine power. If the ternary catalyst in the rear section of the car exhaust pipe is damaged, the electronic control unit will detect it. At this time, ecu will limit the power output of the engine, so the damage of the ternary catalyst will affect the power of the car.

4. The exhaust pipe of the pedal motorcycle will not affect the power of the car. In general, if the exhaust pipe is rotten, it will not affect the power performance of the motorcycle. The exhaust pipe is composed of exhaust manifold, silencer and pipe, and its damage has nothing to do with the power of the motorcycle. The power of a motorcycle mainly comes from the force generated by the engine.

Where is the exhaust manifold

The exhaust manifold is in the engine compartment.Generally, the exhaust manifold can be seen when the engine cover is opened. The exhaust manifold is connected to the exhaust pipe of the engine. The car engine will produce exhaust gas after work. The exhaust gas will be discharged into the exhaust manifold through the exhaust pipe, and then the exhaust gas will be discharged all the way into the atmosphere along the exhaust pipe. If there are four cylinders, there are four exhaust manifolds.

The automobile intake manifold is located in the engine compartment, between the throttle valve and the engine intake valve. After opening the engine cover, it can be seen that the function of the intake manifold is to send the combustible mixture supplied by the carburetor to each cylinder. The function of the exhaust manifold is to collect the exhaust gas after the work of each cylinder and send it to the exhaust pipe. And the silencer, and then put it in.

In the engine compartment of the car. According to Pacific Automobile Network, the exhaust manifold is in the engine compartment of the car. When most of the engine covers are opened, the exhaust manifold can be seen, which is connected to the exhaust pipe of the engine.

The part above the exhaust pipe under the bumper is the exhaust manifold. The exhaust pipe has three parts. The exhaust pipe consists of the head section, the middle section and the tail section. The first part of the exhaust pipe is the exhaust manifold, the middle part is the longer pipe on the chassis, and the tail is the part close to the rear bumper.

The exhaust manifold is made of metal, and there will be some rust on the general exhaust manifold. It is easy to find the exhaust manifold after opening the engine cover. The exhaust manifold is also known as the exhaust head segment. The exhaust pipe of the engine consists of three sections, namely the head segment, the middle segment and the tail segment.
