What is a damper?

Question 1: What is a damper? When you say damper, you can choose one of the following two options:

1. Doors with glass and screens are usually called factory doors, which are usually installed on the outside of house doors, and some are installed on the inside. Play the role of wind and mosquito prevention.

2. At the air inlet of the engine, there is a valve to adjust the air intake.

Question 2: What is a throttle? Throttle is a throttle, which controls the amount of air entering the "oil-gas mixing chamber" in lubricating oil, thus controlling the concentration of oil-gas mixture.

Question 3: What is the function of motorcycle shock absorber? The throttle valve is the choke valve, which controls the amount of air entering the "oil-gas mixing chamber" in the lubricating oil (on the lubricating oil) to control the concentration of the oil-gas mixture.

The usual position is the lowest, and the air inlet at the top position is the least, followed by the middle. In other words, the top oil-gas mixture is the thickest, followed by the middle, and the bottom is in normal use. When the car is difficult to start, first hit the top (the highest concentration), then hit the middle position immediately after starting, and wait 1 to 2 minutes, then you can hit the bottom normal position. In this way, the car can run normally. Never raise the throttle of a cold car, or it will damage the car.

Question 4: What is an outdoor door? This kind of damper is called choke valve, which can prevent outside air from entering after opening. When the motorcycle is difficult to start in cold weather, opening it can prevent cold air from entering, which can improve the ignition temperature and mixing ratio accordingly. The engine is easy to ignite successfully, but it is usually turned on to increase the fuel-air mixture ratio, and the engine spark plug is easy to ignite.

Question 5: What kinds of underground dampers are there? What are their uses? Answer: According to the different uses and opening methods of air doors, air doors can be divided into ordinary air doors, regulating air doors, automatic air doors and reverse air doors. Ordinary damper is used to cut off the airflow in the roadway, which is opened by manpower and closed by self-weight and wind pressure difference. Often set in pedestrian lanes or lanes with less traffic. The damper is similar to the ordinary damper in structure, except that a damper window is set above the damper to limit the air flow through the roadway. Automatic air door is a kind of air door that can be automatically opened and closed by external force, which is suitable for the roadway where harvesters often pass. The reverse air door is the place where the air door is set between the main air inlet tunnels in the mine. At the same time, a reverse damper should be set to open and close normally when the wind blows. Reverse damper can be divided into reverse damper and outburst prevention reverse damper.

Question 6: What does the throttle mean? Carburetor cars are used for cold start! In order to increase oil intake. . In this way, the car will not stall easily!

Question 7: What is the damper on the car used for? What's the role? Air door, also called choke door, is used to adjust the air intake.

The function of choke valve is to reduce the amount of air entering the carburetor air inlet, increase the oil pressure at the fuel injection port, and improve the mixture concentration. This makes it easier to start.

There are two choke structures. One is the automatic electric damper. Before using this shock absorber to start the engine, press the accelerator pedal and the automatic shock absorber will automatically turn off. Then turn on the tripod fire switch, which makes it easier to start. Because it is controlled by electric heating wire, the air door will open automatically after a few minutes of power supply. The whole process does not need the driver's operation, so it is called automatic damper. There is also a manual damper. The driver controls a cable by hand and directly controls the opening of the choke valve to adapt to the change of concentration of various mixtures. Manual throttle is intuitive and stable, and no adjustment is needed. Only the driver's hand feeling can be used to grasp the length of the pull wire to adjust the mixture concentration. But some drivers are not familiar with this structure. When starting the engine in winter, I like to pull out all the shock absorbers. In fact, it is not only expensive, but also difficult to start. Because of the high concentration of mixed gas after the choke valve was pulled, the electrode on the spark plug was stuck by oil droplets, but the fire did not jump and the engine could not be started. This is what we usually call drowning. Experience tells us that it is best to start the choke from one third to one quarter. If you are not in a hurry, you'd better let the engine run for about five minutes, and then put the choke back. If the engine speed is unstable, you should pull the choke out a little more and you can drive. However, you cannot drive at high speed. Because gasoline is particularly expensive at this time, the engine cannot exert its maximum power, and the exhaust emission of the engine will seriously exceed the standard.

This is an organ of the carburetor era. What else is on the agricultural vehicle? There is no such thing on the EFI car now.

Question 8: What does a car damper mean? What is its function? Carburetor cars are used for cold start! In order to increase oil intake. . In this way, the car will not stall easily!

Question 9: What is the function of the air door of the car? The damper blocks the wind and is used to adjust the air intake. 1, preferably in winter, not too much, too much will lead to no air, 2. If you pull it, you can't find it. If there is nothing wrong with other parts of your car, 3. No, for a mulberry car, it doesn't have a manual throttle. Pulling a little wind resistance will improve the speed, but it is not used to preheat the car. Can be used for a short time.

The following are some theoretical viewpoints:

Finally, remind drivers and friends that after the engine water temperature reaches 40 degrees, the choke valve must be put back in place. Otherwise, it will not only waste fuel, but also form carbon deposit in the cylinder, accelerate cylinder wear and shorten engine life.

It is difficult to start in winter, mainly relying on carburetor engine. When designing this kind of engine, considering that gasoline is not easy to evaporate in winter and it is difficult to start, the choke valve is specially designed.

What are the advantages of preheating the car before driving?

In most people's minds, people always think that when you want to use the car early in the morning (or after a long time without using it), you should warm up the car at idle speed and wait for three to five minutes before you go on the road, which is most beneficial to the car. But in fact? Are you sure this is the right way to warm up the car? According to a statistic, more than 90% engine parts will be worn within three minutes after the cold car is started. Therefore, how to heat the car correctly is believed to be a topic of concern to all car enthusiasts. But before explaining how to make hot cars, let's first understand why cars need hot cars.

1, you can warm the car correctly only after you know the cause of hot car. There are three reasons for this:

First of all, after the car is parked for a long time, the engine oil will flow back to the oil pan at the lower part of the engine. Therefore, start the engine after not using the car for a long time (such as overnight), when the upper part of the engine is in a state of no oil and no lubrication. It takes about 30 seconds after the engine is started. Due to the operation of the oil pump, the oil will be transported to the piston, connecting rod and crankshaft that need lubrication most. However, even if you start the engine and go on the road immediately, as long as you don't slam on the accelerator and keep driving at a low speed, the effect is the same as idling.

Secondly, before the engine reaches its operating temperature (about 90- 1 10 degrees Celsius), its oil supply system can't effectively vaporize the gasoline completely, because the temperature of the gasoline is very low (I believe everyone knows that the liquid will vaporize when it reaches the boiling point). When gasoline is a wet liquid before gasification, it is not easy to burn and start the engine. At this time, it is necessary to rely on the function of choke to prevent some air from entering the cylinder, so as to improve the gasoline/air mixing ratio and increase the engine speed, so that the engine will not stall. When it reaches the normal working temperature, the automatic choke valve will naturally return to the normal state due to mechanical action; Cars with manual choke must remember to put the choke back, otherwise, due to the high oil-gas mixture ratio, it will not only waste gasoline, but also lack horsepower, and the gasoline will emit black smoke if it is not completely burned. It takes about seven or eight minutes to reach the normal working temperature of the cold engine ... "";

Question 10: What does the motorcycle throttle mean? Throttle's full name is choke. By operating it, the intake air can be reduced, the concentration of gasoline in the mixture can be increased, and the engine can be started smoothly when the car is cold.
