Wuling Hongguang S engine compartment,The inlet pipe is that one.,I know to tell me.,Thank you.。

From the positive pole of this battery, there is a transversely curved tube that feels like an inlet pipe, and our judgment of this kind of thing is not so memorable, that is, to see which pipe is connected to the fuel injection rail.

It is generally used to hold the hose in place with a normal clamp because it does not have much pressure. Event-related couplings are required, and pressure sealing cannot be guaranteed using ordinary shelves alone.

1. First of all, the switch of the engine cover lock can be found in the position shown in the cockpit of the vehicle.

2. After that, the engine compartment cover can be unlocked by flipping the switch by hand.

3. After the engine compartment cover is unlocked, you also need to pull the wrench shown in front of the engine cover by hand.

to open the engine cover.

4. After that, you can use the hydraulic rod to support the engine compartment cover.

Which one next to the dipstick is to thank you.

Normally, the inlet pipe is above the fuel injector, and the return pipe is below, branching out from the inside, and the inlet pipe is generally larger than the return pipe The inlet pipe is the one connected to the fuel filter.

The function of the oil return pipe in the car fuel tank is to let the excess oil flow back to the fuel tank and reduce the consumption of oil. When the fuel pump provides more oil than the optimal amount of oil required by the engine, the oil is returned to the tank through the return line.

Automobile oil inlet pipe oil discharge method:

1. You can open the oil drain rose, of course, you can't put it without the oil drain.

3. You can disassemble the oil return pipe of the engine and connect the oil while driving the car. Be careful not to allow the oil to spill out, especially not on the discharging system. Easy**. Of course, there are a small percentage of cars that don't have a fuel return line at all. That's not going to work.

4. You can remove the oil inlet pipe, find the oil pump relay, use the wire to cross the oil pump relay to make the oil pump work, and connect the oil from the oil inlet pipe of the engine.

5. This is a commonly used method of oil discharge for gasoline EFI vehicles, and it is convenient to use that method.

The one under the Wuling Hongguang air intake pipe is the crankcase air vent.

When the crankcase vent pipe is working in the engine, the high-pressure combustible mixture and combustible gas in the combustion chamber will more or less leak into the crankcase through the gap between the piston group and the cylinder, causing blow-by. The composition of blow-by gas is unburned fuel gas, water vapor and exhaust gas, which will dilute the engine oil and reduce the availability of the engine oil.

Water vapor condensation will form sludge in the engine oil and block the oil path; Acid gases in exhaust gases are mixed into the lubrication system, which can lead to corrosion and accelerated wear of engine parts; Blow-by gas can also make the pressure of the crankcase too high and destroy the seal of the crankcase, so that the oil leaks and loses.

Crankcase ventilation method

The mixture in the crankcase is directed to the appropriate position of the intake pipe through the connecting pipe, and returned to the cylinder for re-combustion, which can not only reduce exhaust pollution, but also improve the economy of starting the scattered machine. Mandatory ventilation is used in automobile gasoline engines, and mandatory ventilation is gradually adopted in automobile diesel engines. Mandatory ventilation can be divided into two types: open and closed.

When the engine is at full load and low speed, the open forced crankcase ventilation device produces a large amount of air string, but the opening of the flow control valve is reduced, and the excess cylinder mixture will be dispersed into the atmosphere through the open ventilation cover, and its purification rate is only about 75%.

The engine compartment cover can be opened in the following ways.

1. First of all, the switch of the engine cover lock can be found in the position shown in the cockpit of the vehicle. Type return.

2. After that, the engine compartment cover can be unlocked by flipping the switch by hand.

3. After the engine compartment cover is unlocked, you need to use a hand wrench to rent the illustrated wrench in front of the engine cover to open the engine cover.

4. After that, you can use the hydraulic rod to support the engine compartment cover.

Hold the switch in the first picture, and the front cover will open;

The second picture is the position of the front cover switch;

The third picture is what the switch looks like after it is turned on;
