The Great Wall Wingle 5 diesel version is difficult to start in the morning, what is the problem?

Hello, reason 1 Dirty fuel injector Answer: After the vehicle is driven for a period of time, due to the chemical reaction of external dust entering and combustion process, it is easy to adhere some gum at the fuel injector site, which will block the normal amount of fuel injection and affect the perception sensitivity of the fuel injector, resulting in poor atomization of gasoline, so that the ignition is delayed and the car is difficult to start. Tips:

Go to a car repair shop or 4S shop to clean the fuel injector. Reason 2 Battery power loss Answer: The battery has a certain service life, and the battery that has been used for a long time will have a low initial starting voltage, such as the dirty oil on the surface of the battery will make the voltage output unstable and cause the body to shake.

Tips: Clean the battery frequently and replenish the electrolyte. Reason 3 Low fuel quality Answer:

Generally speaking, the viscosity of fuel is higher in autumn and winter, and it is not easy to evaporate, which has a certain impact on the heat energy during combustion. Tips: Choose regular gas stations to refuel, don't be greedy for cheap and low-priced oil.

Reason 4 Throttle carbon deposition Answer: Throttle carbon deposition will affect the perception of throttle and air intake, resulting in computer transmission signal lag or even error, resulting in abnormal conditions such as vehicle failure to start and even accompanied by jitter. Tips:

Hello! The fuel of diesel vehicles adopts compression ignition type, and it is normal for it to be difficult to start when the starting temperature is low. If the starting temperature is right and it is difficult to start, there are many reasons:

1.Poor air intake or uncleanliness. 2. The battery power is insufficient.

3.The battery wire is not in good contact. 4.

The starter is weak. 5.Starter teeth or flywheel ring gear are worn.

6.The fuel injection pump and the fuel supply advance angle are abnormal. 7.

Abnormal valve or valve mechanism. 8.Steel sleeve, piston wear.

It is recommended that you go to a professional repair point to check the repair according to your own situation.

Hello! It is recommended to clean the throttle treatment, I wish you a happy car! If my reply can help you, please help choose it, thank you very much!

Hello! It is advisable to clean the throttle and check the spark plugs. Hope it helps.

Fault phenomenon: the car was replaced with clutch pressure plate, clutch plate and release bearing in a repair shop due to clutch slippage, and the repairman found it during the disassemblyCrankshaftThe rear oil seal leaked, so 1 crankshaft rear oil seal was replacedIt is equipped with a flywheel, clutch plate, pressure plate and transmission.

After installation, when the engine is started, the starter is running normally, and the engine never starts.

Settle. First align the mark of the crankshaft pulley with the mark on the timing cover, and then look at the T letter on the flywheel (this is not to know that there is a mark on the flywheel after consulting after the car) is not on the top, but deviates to the left 2 holes, sure enough, the flywheel is installed incorrectly.

The repairman removed the 8 bolts on the flywheel, turned the flywheel, turned the mark T letter to the top, installed the flywheel bolts, and installed the double transmission. Test run, start the engine, the starter is running normally, the engine still can't start, and the fault is still not eliminated.

There are several reasons why the EFI diesel car cannot be started: 1. The fuse is burned 2. There is no fuel in the fuel tank 3. The fuel tank outlet pipe is blocked 4. There is air in the fuel system 5. The starting relay is bad 6. The fuel pipe or fuel filter is blocked 7. The fuel injection is poor or the spray pressure is too low 8. The injection advance angle is incorrect 9. The electrical equipment joint is loose 9. The controller EUC power supply is abnormal 10. The battery is insufficient and the flywheel speed is not enough 11. The starter motor is damaged 12. The temperature of the diesel engine is too low 13. Toulon speed sensing installation clearance problem or sensor damage 14, cam, crankshaft sensor or temperature and pressure sensor power supply short circuit to ground 15, fault diagnosis switch open before starting 16, controller ECU damage (internal components damage) 17, incorrect phase (timing) 18, starting oil volume is too small 19, control program mismatch 20, back pressure valve failure 21, ground wire disconnection.

The situation you mentioned may mean that the vehicle has the following three conditions:

1.The engine has a lot of carbon deposits.

The most common cause of car shake is a dirty throttle or excessive carbon build-up in the fuel injector. When the carbon deposition inside the engine is excessive, the gasoline sprayed by the cold start fuel injector will be absorbed by the carbon deposition in large quantities, resulting in the mixture of cold start being too thin, making it difficult to start, in this case, only when the gasoline absorbed by carbon deposition is saturated, it is easy to get on the car, and the gasoline adsorbed on the carbon deposition after the car will be sucked into the cylinder by the vacuum suction of the engine for combustion, and the mixture becomes thick, and the combustible mixture of the engine is dilute and thick, causing idle shaking after cold start. The lower the temperature, the greater the amount of oil required for the cold start, and the more carbon deposits will affect the smooth cold start.

Solution: Clean the oil circuit and check whether the idle motor has carbon deposits and should be cleaned.

2.Problems with the ignition system.

Check the working condition of the spark plug, high-voltage wire and ignition coil, the ignition system is not working well, and the spark plug tripping condition is not good, which will also lead to this kind of failure.

Solution: Check whether the spark plug has too much carbon deposit, and replace the spark plug.

3.The oil pressure is unstable.

If you have cleaned the engine carbon deposit, washed the throttle, changed the oil pad and spark plug, etc., and still found that the body shakes when idling, it is recommended that you go to the 4S shop to check whether the fuel supply pressure and intake pressure sensor are normal, if the oil pump supply pressure is abnormal or the intake pressure sensor value is wrong and the work is not good, the body shake will be triggered.

Solution: Check the oil pressure and replace the parts if necessary.

4. Aging of engine parts.

Car jitter is also related to the aging of the engine feet (also known as claw pads). The engine foot is actually the suspension system of the engine, and the engine foot is responsible for absorbing the subtle shake of the engine when it is running, and if there is a problem with the engine foot, these vibrations will be transmitted to the steering wheel and cab, causing shaking when idling.

Workaround: Replace the parts.

Summary. Hello! The Great Wall Wingle can not start without ignition, you must first check the oil circuit and circuit, first see if your car has electricity, the horn is not sound, if there is electricity, you also need to check the high-voltage bag, ignition coil, motor, flywheel gear ring, spark plug and many other factors, the oil circuit to pull out the tube on the side of the fuel injector, start to see if there is oil sprayed out, if there is no oil injection nozzle.

Hope mine helps you! ☺️

Hello! The Great Wall Wingle has oil without ignition and knows that it cannot be started, you must first check the oil circuit and circuit, first see if your car has electricity, the horn is not sound, if there is electricity, you also need to check the high leather Qiao Ming pressure bag, ignition coil, motor, flywheel gear ring, spark plug and many other factors, the oil circuit to pull out the tube on the side of the fuel injector, start to see if there is any fuel spray, if there is no oil sprayed out, if there is a look at the fuel injector can not produce oil. Hope mine helps you!

You can click on the lower left corner of the key to give me a thumbs up, and it's my honor to give you a good answer

Your likes are important to me

The oil circuit is fine, there is also electricity, gears, and the ignition coil is also normal.

The reason why the car does not catch fire when there is electricity and oil may be that there is a problem with the fire line, and there are problems such as aging of the split line, wrong cylinder line sequence, or damage to the power distributor, spark plug cap and other problems.

Discharge the above situation can be judged to be the spark plug is loose, and the spark plug can be tightened to restore the smile and dress up to normal. Hope mine helps you! Bumper the stove

There is no power supply on the ignition coil.

The reasons for the ignition coil to be out of power are as follows: 1. Check the spark eggplant plug first, and then carry out the "skip fire" experiment if there is no problem with the spark plug, that is, pull out the spark plug and go to the car, and see the "jumping" situation of the spark plug.

Summary. Hello, happy to answer your questions.

Hello, happy to answer your questions.

Hello, first check the diesel filter to see if it is time to change the chain and whether there is moisture. Then look at the oil viscosity. Is there a problem with the speed of the motor when the early state is paired with the sail and the finger is moving.

The diesel version of the Wingle 5 is not easy to start after the overhaul.

Overhaul words. See if there is a problem with the cylinder pressure and how about the power?

Open the key a few more times and be quick to get better Two days ago, the inspection said that it was early sleepy and preheated and broken After the change, it was the same It was the same It was no problem after the last overhaul It was good Now it's okay to be in it once It's the same after the cold.

Is there a problem with the new preheater? If you open the key a few more times, the preheater will work for a longer time, and the preheating temperature will be higher

The diesel carrier has done an experiment of minus 35 degrees, and there is no problem with the ignition.

This diesel engine was tested in the northernmost Heihe. As long as it is not in Russia and the Arctic, there is not much problem in China. Remember, though, to switch to low-grade oil in winter.

Generally, there is an automatic heating and low-temperature starting device, just open the electric door and start it again. As long as the normal maintenance, the use of ** oil and three filters, the rest do not have to worry.

Let it be more after playing, listen to the engine sound become normal and then start, start slowly, you will feel bored at first, and wait for the car to run hot.

Diesel is a light petroleum product with a mixture of complex hydrocarbons (about 10 22 carbon atoms). Diesel fuel. It is mainly composed of diesel fractions produced by distillation, catalytic cracking, thermal cracking, hydrocracking, petroleum coking and other processes; It can also be produced from shale oil processing and coal liquefaction.

It is divided into two categories: light diesel oil (boiling point range of about 180 370) and heavy diesel oil (boiling point range of about 350 410). It is widely used in large vehicles, railway locomotives, and ships.
