The overhauled engine, the Volkswagen EA211 engine, can t hit the car, there is fire and oil, and it

The spark plug insulator skirt and electrodes are damp and oily. This indicates that the high-voltage line of the cylinder has no electricity or weak electrical energy. or a faulty spark plug, causing the cylinder to fail to ignite. The spark plug should be replaced in a timely manner.

The common fault phenomena of spark plugs are as follows:

1. The spark plug electrode is melted, and the insulator is white. This indicates that the temperature inside the cylinder is too high, causing the spark plug to be ablated. The reasons may be too much carbon deposit in the cylinder, too little valve clearance, too late ignition, too thin and damaged spark plug seal, failure to tighten the spark plug according to the specified torque, poor engine heat dissipation, etc.

2. The spark plug electrode is rounded and the insulator is scarred. This indicates that the engine was pre-ignited, and the reason was that the ignition time was too early, the gasoline octane number was too low, and the calorific value of the spark plug was too high.

3. The top of the spark plug insulator is broken. This indicates that the engine was detonated and burned, and the insulator was cracked by an instantaneous shock wave of excessive pressure. The reason for this is that the ignition time is too early, the octane number of gasoline is too low, there is serious carbon deposition in the combustion chamber, and the temperature is too high.

4. There are gray-black stripes on the top of the spark plug insulator. This indicates that the spark plug has cracked and leaked, and the reason is the same as above.

5. There is oily deposits between the top of the spark plug insulator and the electrode. This indicates that the lubricating oil has entered the cylinder and participated in the combustion. If only a few spark plugs have deposits, the cause is the failure of the valve stem baffle; If all spark plugs have deposits, it is a blockage in the air filter, crankcase ventilation, etc.

6. There is black deposit between the top of the spark plug insulator and the electrode. This indicates that the mixture burns poorly, mainly because the mixture is too thick, leaving this black layer of soot on the spark plug.

7. There is gray deposit between the top of the spark plug insulator and the electrode, which is usually due to the fact that the quality of gasoline does not meet the requirements, and the additives in the gasoline are produced after combustion, which will reduce the ignition performance of the spark plug.

8. The skirt and electrode of the spark plug insulator are damp and smell of oil. This indicates that the high-voltage line of the cylinder has no electricity or weak electrical energy. or a faulty spark plug, causing the cylinder to fail to ignite.

When it is not easy to see the quality of the spark plug from the appearance, it can be checked by the flashover method: remove the high-voltage wire head and jump the fire at 4-5mm away from the surface of the cylinder head, and then use the spark plug to jump the fire with an iron to observe the sparks of the two. If there is a weak spark or no spark when jumping with a spark plug, and there is a strong spark when jumping with a high-voltage line, it means that the performance of the spark plug is poor (the spark plug has leakage) and should be replaced.

If there is fire and oil, it is sick of air intake, and oil atomization is not good.

There will be no misfire, and if it is slightly damaged, it will be fuel-efficient, and serious damage will likely cause damage to the engine.

Possible causes of engine misfire: 1. Ignition system failure: The ignition system failure problem is the key cause of the ignition system fire in the first cylinder of the car, and the ignition system failure problem includes the spark plug.

Failure problems, ignition coils.

Therefore, when the ignition system of the car has a faulty problem, the fuel and mixed gas of the car can not be ignited normally, so it will cause the car engine.

The phenomenon of lack of cylinders will affect the power of the car.

Variability, engine trembling and vibration, etc. In this case, the ignition system of the car should be detected, and the spark plug should be changed immediately and the oil pipeline hidden in the automobile chain should be dredged.

The purpose of the high-pressure fuel pump on the car is to deliver high-pressure fuel to the oil distribution pipe inside the car, and the accessory on the car is one of the things that make up the EFI car fuel injection system.

The cause of the engine fire and the symptoms of the early occurrence of Zhensun.

Engine cylinder lack and misfire is a meaning, but the name is different, cylinder lack and misfire both refer to a cylinder or multiple cylinders in a multi-cylinder engine does not work or can not work normally; After the failure of missing cylinder misfire, the engine will have severe shaking, resulting in insufficient power, weak acceleration, high fuel consumption, and if it is a multi-cylinder misfire, the engine may not start.

Special attention should be paid to the fact that some cars will still inject fuel from the fuel injector when they lack cylinders, so that the unburned gasoline mixture enters the exhaust pipe and continues to burn where the three-way catalytic converter is located, resulting in the three-way catalytic converter being scrapped due to high temperature.

The causes of engine misfire can be divided into two main categories.

1. Failure of the electronic control system, such as sensor signal loss or signal inaccuracy, wrong control signal or no signal output, failure to ignite due to damage to the spark plug or ignition coil, no fuel injection from the fuel injector and line failure, etc.

2. Mechanical failure, mainly due to insufficient cylinder pressure, such as valve closure is not tight, air leakage, the gap between the cylinder, the piston, and the piston ring is too large, resulting in insufficient compression ratio in the cylinder.

The lack of cylinders in the engine will bring great harm: the speed and power of the engine will decrease. Increased fuel consumption and emissions of pollution. Aggravate the wear of the running parts and shorten the service life of the lubricating oil. The engine is missing cylinders and needs to be overhauled in time.

The solution to the lack of cylinders in the engine:

1. Circuit failure: spark plugs, cylinder wires, ignition coils, etc. are damaged, and it is easy to lack cylinders. You can use the broken fire to determine which cylinder parts are damaged, and replace the damaged parts;

2. Oil circuit: If the oil circuit is not cleaned for a long time, there will be more gum and magazines in the oil circuit, and the fuel injector will be blocked. The oil cut-off test is used to detect the fault point and carry out maintenance;

3. Mechanical failure: The internal piston, connecting rod, piston ring, piston pin, etc. of the engine are faulty, which will generally be accompanied by obvious abnormal noise, and obvious metal chips can be seen when detecting the oil. Generally, this situation requires the engine to be dismantled.

Hello If there is a frequent misfire in the second cylinder, please replace the spark plug, ignition coil and fuel injector into other cylinders that do not misfire, use a special computer to read the data stream, and observe whether the misfire cylinder is transferred.

Many friends reported that the power of this engine was not enough. The Volkswagen EA211 engine is a key power mode, with a maximum power of 96kW and a maximum torque of 225Nm. This power may be insufficient when the car is fully loaded or going uphill.

After adjustment, the high-power version of the EA211 engine can reach 110kW, which can also meet the usual power demand. The EA211 engine is made of all-aluminum, which has a great advantage in weight. At the same time, it is one of the core technologies of Volkswagen's MQB modular platform, and the quality is still very high.

Attached: Volkswagen EA211 engine advantages:

1.Light weight:

This is the core of the design of the Volkswagen EA211 engine, which reduces part of the mass of the EA111 and reduces the pressure in the car. At the same time, it optimizes the technology, increases the overall practicality of this engine, and the lightweight design also adds many features to this engine.

2. Fuel saving: This is also the biggest advantage of the Volkswagen EA211 engine, and it is also a place that many consumers will pay great attention to when buying a car. The reason why the Volkswagen EA211 engine is quite fuel-efficient is that this engine uses a closed cylinder system.

The working principle of the cylinder closure system is that when the car rotates at low load, the second cylinder and the third cylinder will automatically shut down, which will reduce the fuel consumption of the car, prevent fuel waste, and then shorten the fuel consumption of the car.

3.Productivity is improved:

Volkswagen EA211 is one of the core technologies of Volkswagen MQB modular platform, optimized and improved in the same level of engine, the use of 5-hole fuel injector in the direct injection system of the engine, adding the efficiency of the engine, so that the car has a considerable advantage in acceleration, which is not available on many engines, and at the same time is one of the highlights of the Volkswagen EA211 engine.

Millions of car purchase subsidies.

Summary. Hello, how to repair the uneven pressure of each cylinder of the Volkswagen EA211 engine: 1

If the friction gap of the cylinder is too large, if the friction is within the maintainable range, the gas cylinder liner can be inlaid and the boring cylinder is being treated; 2.Piston ring blowing, can be replaced with a new piston and piston ring 3If the cylinder pressure is insufficient, it should be repaired at the 4S shop in time.

Hello, how to repair the uneven pressure of each cylinder of the Volkswagen EA211 engine: 1If the friction clearance of the cylinder is too large, if the friction degree is within the repairable range, the gas cylinder liner can be inlaid and the cylinder is boring; 2.

Piston ring blowing, can be rubber to replace the piston and piston ring 3If the cylinder pressure is insufficient, it should be repaired at the 4S shop in time.

Reasons that may lead to insufficient cylinder pressure: the piston ring is professionally matched, the wear is too large, and the cylinder is not enough lubricating oil to cause the engine to pull the cylinder, resulting in excessive damage to the cylinder wall. In this case, the piston ring or cylinder liner should be replaced, and the piston rod crankshaft and other components should be replaced together in more serious cases.

The sealing of the cylinder gasket is poor or damaged, resulting in insufficient sealing between the cylinder block and the cylinder head, resulting in insufficient cylinder pressure. If the cylinder gasket is damaged, the cylinder gasket should be removed and replaced again, and the screws should be tightened according to the specified torque. The floor plan of the two sides where the cylinder head and the cylinder block are in contact is too large, resulting in the lack of tight sealing of the cylinder, resulting in insufficient cylinder pressure.

The cylinder head must be removed and smoothed with a skilled CNC grinding machine. The intake and exhaust valves are not closed tightly. Valve damage, bending, breakage, excessive valve clearance, and insufficient valve spring elasticity may all cause insufficient cylinder pressure.

Damaged or corroded valves should be removed and replaced with new ones. Common faults in the automotive refrigeration system lead to insufficient heat exhaust of the automobile engine, and the cylinder block continues to be at high temperature, resulting in the locking of the piston rod and the cylinder block wheels, resulting in damage to the engine cylinder, resulting in insufficient cylinder pressure. Check whether the waterway is smooth, pay attention to the addition of cooling circulating water, and immediately remove the seepage area.

Does it have anything to do with idle jitter?

It's a bit of a relationship.

My car is a cold car, and the hot car is much better when it starts.

If the car starts shaking in the cold, warm up the car before starting.

It's normal to drive a hot car, and there is no fault with the computer.

It is because the screen time is used for too long, which causes many trivial files to occupy the system memory and crash.

It doesn't matter if you don't fix it.

Yes, it doesn't have a big impact on the car.

When the master withdrew the cylinder pressure, I saw that each cylinder pressure was different.

Summary. Hello dear, the cylinder pressure of the Volkswagen EA 211 engine is uneven. First, in this case, the first is to consider the cause of carbon deposits inside the engine, and it is necessary to clean the carbon deposits inside the engine, including valves, bases, carbon deposits, and carbon deposits in the cylinder In the second case, consider the vehicle engine.

When there is a problem with the timing, you need to check the official markings related to the engine. The third is that there is a problem with the engine head gasket of the vehicle, and it is necessary to check the state of the head gasket Finally, considering the wear of the cylinder inside the vehicle engine, then this situation can only be decomposed for overhaul. Kiss Blessings to you, good health and family, and if my answer is helpful to you, please give it a thumbs up.

Good luck! Good luck!

I have a three-cylinder car, but one cylinder is 6 pounds, and the other 2 are 15 pounds, what is the problem?

In this case, the probability of problems with the internal valve mechanism of the engine or the cylinder barrel piston is relatively large.

How do I repair it?

It's time to disassemble the engine for overhaul.

Is it that serious?

Hello friend, this cylinder pressure is six, which is obviously too low.

2 years car. The vehicle is still under warranty, right?

The years are there, but the mileage has exceeded 100,000 kilometers.

Then this can only be repaired by the relevant engine imitation hunger, and there is no good way. Let's take a look at the head head first, is there a problem? If you don't have a limb to ask the rubber question, then this can only be dismantled by the engine.

In your case, there is no need to repair it in a 4S shop, and you can go directly to a more professional repair shop outside for maintenance, which is much cheaper.

How much does it cost to repair the repair?

Hello friend, the cost of repairs in an outside repair shop is about 6,000 to 7,000.
