Land Rover Freelander 2 3 2 displacement how to clean the fuel injector

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.

The injector is a simple solenoid valve. When the solenoid coil is energized, a suction force is generated, the needle valve is sucked up, and the nozzle hole is opened. The fuel is sprayed 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, which is conducive to full combustion.

As one of the key components of the EFI engine, the fuel injector will seriously affect the performance of the engine.

The reason for the blockage is that the carbon deposits in the engine are deposited on the injector, or the impurities in the fuel block the injector channel, and the injector is blocked, 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 additives, which are non-corrosive and do not hurt the car. 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.

It can be cleaned without dismantling and cleaning.

Summary. Hello, I am your exclusive elite technician, we promise to be attentive, careful, and attentive to answer your car questions. Hello, there are two ways to clean the fuel injector of this Land Rover Freelander displacement, one is to add it to the fuel tank, one is to clean the fuel injector by combustion, and the second is to remove the fuel injector and clean it by power and pressure.

Of the two options, the second method is more thorough and cleaner, but it is also more expensive.

Hello, this question can give you a perfect reply, wait for me to sort out the information, I'm typing, 2-3 minutes, don't finish.

Summary. Hello, Land Rover Freelander II diesel version of the oil pump can be cleaned, before cleaning, some of the relevant seals of this seal ring should be removed and put aside, can not be soaked with cleaning agent, soaking oil will cause the seal to lose elasticity and rupture. The high-pressure oil pump** for this model is between 3450 and 3600 dollars.

In the case of this model, this oil pump is also a common problem, which is relatively easy to damage, and after replacing the oil pump, it is necessary to exhaust the air for the entire oil circuit.

Freelander two, yes, it's like the oil can't keep up with the sudden shutdown of the car while driving, and it can start again after a while, what's going on?

Hello, it is the fuel system of the vehicle that is faulty, resulting in a blockage of the oil circuit or a combustion imitation basis oil pump that is not working properly. It is advisable to check whether there is a problem with the fuel filter, fuel pump, fuel line, etc., or if the fuel pump is not working properly due to a faulty circuit. At the same time, you can also check whether the ignition system and air filter of the vehicle are working properly to ensure that the vehicle can start and drive with the right leather.

Gasoline pressure sensor, if there is a problem, suddenly turn off, wait a minute, start the car, and it's okay again.

Hello dear. A problem with the gasoline pressure sensor will cause the engine to stall, and waiting a few minutes before starting the vehicle may return to normal. The solution is to check if the gasoline pressure sensor is damaged or malfunctioning, and if there is a problem, the sensor needs to be replaced or repaired to ensure that the vehicle is functioning properly.

Carbon deposits are the product of high-temperature oxidation of fuels and lubricants. In the combustion chamber, the oxygen ** is insufficient, and the fuel and the lubricating oil that escapes into the combustion chamber cannot be completely burned, and the oil smoke and tar particles are produced, which are mixed with the lubricating oil and further oxidized into a thick colloidal liquid - hydroxy acid. The hydroxy acid is further oxidized into a semi-fluid resinous gum, which is firmly adhered to the part, and under the continuous action of high temperatures, the gum is polymerized into a more complex polymer - hard cemented carbon, which becomes carbon deposit.

The function of "fuel treasure" is to clean the oil circuit and carbon deposits, the effect in the short term is not obvious, but it will indeed be good for the vehicle, it is recommended to buy a few more sets of long-term use, the effect will be very obvious, the current better fuel treasure on the market has magic particle fuel, Goodway fuel and other brands.

There are several ways to reduce, prevent, and remove carbon deposits in daily life.

First: refill with high-quality gasoline.

Second: Don't idle for long periods of time.

Third: run more high-speed and try to increase the shift speed of the hand-stop car.

Fourth: Use fuel cleaning and cleaning additives.

Fifth: dismantle the machine for cleaning.
