Who knows what the two water pipes on the throttle body do?

Function: 1. The water pipe on the side is to return the exhaust gas to meet a certain emission standard.

2. The water pipe is used to heat the throttle body. Because the climate in the north is cold. The velocity of air out of the throttle valve is high, and it is easy to freeze in winter. In order to avoid this situation, hot water is drawn from the cylinder head to heat the throttle body, which belongs to a small cycle.

The throttle body is a valve that controls how much air is sucked into the engine. It is a circular steel sheet with a shaft in the middle, which is connected to the throttle cable and controlled by the throttle cable.

It is a bypass air control system, which is a paraffin valve, which uses cooling water to heat paraffin, and uses the thermal expansion and contraction characteristics of paraffin wax to control a bypass air channel, which is mainly used to improve the air intake of the chiller when it is about to idle.

The volume solution is as follows:

Solution 1:

Control the idle motor to adjust the valve opening to a smaller throttle, and there is a temperature sensor on the valve at this water pipe position. However, the technology is outdated, the role is to let the throttle know the level of water temperature, after the water temperature rises, when the water temperature is low, the temperature sensor controls the idle motor to open a large degree, which is why the standby speed changes from high to low when the cool car starts.

Solution 2:

Heat dissipation, because the valve works at high temperatures, if it is not dissipated in time, it will lead to a series of failures.

Solution 3:

Heat dissipation is one thing, and I guess it might also prevent the throttle from freezing!

Solution 4:

Heat the throttle.

It is to use the temperature of the engine coolant to increase the atomization of gasoline.

Will the water on the throttle body flow into the oil?

This pipe is called a wastehead.

The function of the exhaust pipe is to extract the exhaust gases of the engine under certain conditions.

Part of the exhaust gas from the engine is returned to the intake manifold and re-enters the cylinder together with the fresh mixture to participate in the combustion work.

Because the exhaust gas cannot be burned, the combustion rate and combustion temperature in the cylinder are reduced, so as to achieve the purpose of improving the emission and can also reduce the content of pollutants.

Not connecting the car exhaust pipe has no effect on the engine, but it has an impact on the environment.

Some unburned gases will be directly discharged into the atmosphere, the car exhaust pipe will not be connected, and the engine may be noisy.

The water pipe connected to the throttle body of the car plays the role of heating the throttle.

In winter, the air of the engine is very cold, which is not conducive to the ratio of mixture, so two small tubes are connected to the cooling system of the engine to incorporate the throttle into the antifreeze circulation, and the throttle is heated through the cooling water of the engine.

In the cold car state, this device does not work, but the engine has a starting enrichment system when the car is cold, so the impact is not large, but the mixing ratio returns to the normal working state after the hot car, and if the inhaled air is too cold at this time, it will affect the operation of the engine, so this device is added.

Throttle maintenance and cleaning steps:

1. Turn on the air intake filter.

2. Remove the intake hose.

3. Open the throttle flap.

4. Use cleaning agent to spray and wash.

5. The operation is completed by installing the return filter system.

In places where the temperature is low, the throttle body freezes, which is avoided by heating through the water pipe. Today's car idling is computer-controlled, and many years ago, it was true that the idle valve could be controlled by the heat of the water pipe, and that was history.

To improve the idle speed of the cold car, many cars will have a higher speed, and the water temperature will drop to normal, and the air intake of the six solar terms will be controlled by the water temperature. I've been a car repairer for twenty years.

The two water pipes are for cooling, and the small pipes above the intake pipes are for exhaust gas circulation.

The throttle valve controls the air to enter the engine, and the gas will mix with gasoline to form a combustible mixture after entering the intake pipe, thereby combusting to form work. It is connected to the air filter and the engine block, which is known as the throat of the automobile engine.

The throttle is one of the most important components of today's EFI engine system, its upper part is the air filter air grid, and the lower part is the engine block, which is the throat of the automobile engine.

Whether the car accelerates flexibly or not has a lot to do with the dirt of the throttle, which can reduce fuel consumption and make the engine flexible and powerful. Whether the throttle should be removed and cleaned is also the focus of much discussion among car owners.

Hello, connect the waste secondary combustion pipe and the vacuum suction pipe of the brake pump respectively.

It's the water pipe, which is for heat dissipation.

The exhaust pipe, which comes from the crankcase for forced ventilation, is also involved in secondary combustion (environmental requirement).

It's not about exhaust oil.
