Do turbocharged cars need to wash the fuel injectors frequently?

The role of the fuel injector is to deliver the fuel precisely to the inside of the engine for combustion. A car fuel injector is a simple solenoid valve. When the solenoid coil is energized, the suction force is generated, the needle valve is sucked up, the nozzle hole is opened, and the fuel is sprayed out at high speed through the annular gap between the shaft needle and the nozzle hole at the head of the needle valve, forming a mist shape, which is conducive to full combustion.

When the fuel injector fails, it will lead to an increase in carbon deposition in the engine, unstable idling, increased fuel consumption, weak acceleration, difficult starting, excessive emissions, etc., and in serious cases, it will cause the fuel injector to be blocked, and then damage the engine.

Reasons for higher fuel consumption:

1. Poor ignition: the spark plug gap is too large, and the ignition coil energy is not enough;

2. Poor atomization of fuel injector: the fuel pressure regulator is faulty, and the fuel pressure is too high;

3. Excessive carbon deposition in the engine: part of the gasoline sprayed is absorbed by carbon deposition;

4. Sensor failure: For example, the failure of the water temperature sensor will cause the engine to be mistaken for a cold state, and will always send out a fuel injection signal, resulting in high fuel consumption;

5. Oxygen sensor failure: the fuel correction will be invalid, the computer will always send out the signal of fuel injection, and the failure of the air flow meter will cause the incorrect air intake data.

When encountering a blocked fuel injector, pay attention to the following points;

First, don't coax the throttle with a big foot, especially if the fuel injector is blocked, which will cause the fuel injector to be completely damaged.

Second, the fault light is not good for a long time, and the fault light will be reported after a certain number of times, indicating that the car is not burning well before, which may be oil or oil deterioration and there is no good fuel to burn.

Third, in the case that the oil circuit is not cleaned and improved, cleaning the throttle will lead to increased air intake, thinning of the mixer, and the vehicle will shake at idle, and the throttle will be channeled.

Fourth, repairing a car does not mean that it will be good, and repairing it may aggravate problems in other places. This is normal and requires the use of elimination.

Fifth, in the case of poor combustion, shaking, and scurrying, the first thing to clean the oil circuit is, and not to rush to replace the accessories.

This is very easy to deal with, encounter such a fault code, after the detection, it has been determined that the fuel injector is blocked, then the traditional way is to disassemble the fuel injector to replace, not to mention the replacement of the labor costs, we will say the reason for this, we have to first figure out why it will be blocked, will be after the replacement, to avoid the later blockage, after all, the replacement cost is very high, you replace the plug again, is it to consume a lot of cost.

There are two types of blockage, one is the external blockage caused by ash and carbon deposits on the outside of the fuel injector in the combustion chamber, and the other is the internal blockage caused by the oil in the oil circuit. Both of these blockages can be cleaned and unblocked by PNF-based additives. But be sure to use effective additives.

Don't wait for the car to have a problem before thinking about changing the parts, the cost outweighs the loss.

Personally, I suggest that it is best to clean the fuel injector once for about 30,000 kilometers, which is more appropriate, and you can refer to it.

It should be cleanable, disassemble the turbocharger inlet hose, use the turbo sludge remover, soak and dissolve the sediment on the supercharger inlet impeller, and then twist the turbo flushing fluid bottle to the cleaning gun, and connect the cleaning gun with a compressed air pipe.

Use turbo flushing fluid to clean and clean the supercharger inlet impeller and intercooler, rinse for 3-5 minutes, dry with a dryer, and install and reset.

In addition, many 4S shops now have professional turbine cleaning, and it is not recommended to buy cleaning agents, because it is easy to hairen the turbine blades if the ordinary cleaning agent is not properly operated.

Although the turbocharger on the car seems to be quite high-tech, its technology is more in the material and machining accuracy, and its structure is actually very simple, that is, an intermediate, supporting an impeller on both sides. One side of the turbine is connected to the engine exhaust manifold, and the high-temperature and high-pressure exhaust gas discharged from the engine pushes the turbine to rotate at high speed, and then drives the pump wheel on the other side to rotate at high speed, pressing more air into the engine, thereby increasing the air intake of the engine, increasing the engine power and torque. That's the basic principle of turbocharging.

So do this turbine and pump wheel need to be cleaned? The answer is no! The pump wheel is in direct contact with the clean air coming in from the air filter and is basically free of any impurities, so it is impossible for it to be dirty.

We touched the pump wheel with our hands, and there was hardly any dust on it, and it was very clean. If the air filter is damaged, or the filtration ability is poor, the impurities and particles in the air cannot be completely filtered out, but the pump wheel may be damaged. Some turbochargers have a lot of pitting on the pump wheel, or the edge of the impeller is jagged, which is caused by poor air filter filtration.

After the turbocharger is used for a long time, there will be sludge and carbon deposits on the impeller, which reduces the working efficiency of the turbocharger and shortens the service life of the turbocharger, so the turbocharger needs to be cleaned regularly, and the cleaned supercharger has higher work efficiency, stronger engine power, and effectively prolongs the service life of the turbocharger.

Turbochargers are maintenance-free and don't need to be cleaned regularly!

Regardless of whether it is a transverse engine or a longitudinal engine, it is equipped with a turbocharger. The restricted area is small, and disassembling the turbocharger is often a big project! Even if you give money, this thing is time-consuming and laborious, and the average repair shop will not dismantle this thing as a last resort, let alone maintenance!

I think it is necessary to clean. Because the turbocharger is cleaned frequently, it will ensure normal use. Therefore, it needs to be cleaned frequently.

The turbocharged car has been driven for a long time, does the turbocharger need to be cleaned?

You can clean the fuel injector and throttle, look at the quality of the fuel, the driving habits of the owner, etc., without a precise replacement time. Generally, the engine is idle and shaken, and the acceleration is weak. Generally, it is more suitable to clean the throttle valve for about 10,000 to 20,000 kilometers, and the fuel injector does not need to be cleaned in the absence of abnormality, or about 50,000 to 80,000 kilometers to clean.

It is necessary to clean the engine fuel injector, and the dirty engine fuel injector will lead to a series of failures such as increased fuel consumption of the vehicle, insufficient power, and idle shake. It is necessary to clean the fuel injectors, and it is also necessary to go to a large gas station to refuel. Because of the poor quality of gasoline, the fuel injector can be damaged due to carbon accumulation.

The throttle and the fuel injector are two things, one that controls the air and the other that controls the fuel.

The throttle valve is a controllable valve that controls the entry of air into the engine, and the gas enters the intake pipe and mixes with gasoline to form a combustible mixture, thus combusting work. It is connected to the air filter and the engine block, which is known as the throat of the automobile engine.

The injector itself is a normally closed valve, and the opening and closing of the valve is controlled by the upward and downward movement of a valve pin. When the ECU gives the injection command, the voltage signal will cause the current to flow through the coil in the fuel injector, generating a magnetic field to suck up the valve pin, so that the valve can be opened so that the oil can be sprayed through the injection hole.

Cleaning is definitely possible.

The turbocharged engine has one more supercharged component than the naturally aspirated one, and nothing else has changed.

And the cleaning of the fuel injector should not affect the washing should be washed as much as I personally feel that the amount of supercharged oil is too much, should I wash more

Turbo Turbocharger Fuel Injection Causes Here's What Happens:

1. Principle analysis:

1.Turbocharger oil leaks generally from the gap between the intermediate and the turbine shaft. Because the exhaust gas turbocharger of a gasoline engine has a turbo speed of 200,000 rpm, it cannot be sealed with the usual rubber seals.

2.The seal that controls the clearance can only be used, that is, the gap is made small, and then the pressure difference formed near the shaft when the turbine is working is used to ensure the seal, but there are two problems: a

In any case, the clearance cannot be zero, which is also the reason why the supercharged engine usually "burns oil"; b.The gas pressure at idle is small, so the seal at idle is the most porous. Both of these situations cannot be avoided and are usually controlled using specialized oil consumption parameters.

Second, there may be four reasons for fuel injection:

1. There is wear, that is, this gap is too big, and there is no way but to change it;

2. It may be that the intake resistance of your air intake system is large, check the air filter; Tend to reason 1, because of the blind 2, can not reach the realm of "fuel injection."

3. First look at whether the oil pipe of the supercharger is blocked, and then consider replacing the supercharger. Splash oil, should be oil sealed. There is little point in repairing, and it is reliable to replace it with a new one.

4. The model should be consistent, otherwise the air supply is not enough, and the pipeline should be firmly sealed, including the exhaust manifold and intercooler. Pay attention to the exhaust gas of the exhaust pipe, the large black smoke is not enough gas or the amount of oil is too large, and the lack of smoke may be due to insufficient oil supply.

The fuel injector can generally be cleaned once every 2 years or 5 to 80,000 kilometers, depending on the quality of gasoline in the area where the vehicle is used.

There are two ways to inject fuel nozzles: one is disassembly and cleaning, and the other is disassembly and cleaning.

It is necessary to clean the engine fuel injector, the engine fuel injector is dirty, which will lead to an increase in fuel consumption of the vehicle, insufficient power, idle shake and a series of failures, I personally feel that the biggest impact is the increase in fuel consumption, after all, the current oil price is so expensive, or a little distressed. It is recommended that it is necessary to clean the fuel injector regularly, and it is also necessary to go to a large gas station to refuel. Because the quality of gasoline is not good, it is a bit more than worth the loss if the fuel injector is deposited or damaged.

Summary. Dear, I'm glad to answer for you, the turbocharger needs to be cleaned once a year. The high power and low fuel consumption of turbocharging are all based on its precise design and manufacturing process, and also determine its harsh working environment.

It has very high requirements for the cleaning and protection of lubricating oil, and the friction damage of any impurities and components is very large.

A car is a vehicle that does not rely on tracks or wires, has four or more wheels on the road, and is powered to drive on land. Each country's car has its own characteristics, which can be divided into sedans and commercial vehicles. There are mainly ordinary cars, live top cars, luxury cars, small cars, convertibles and so on.
