Injectors are one of the main fuel delivery elements in petrol and diesel engines. They perform the task of atomizing the fuel and are small holes through which fuel is injected.
The fuel supply occurs at high temperatures, which leads to rapid plugging of the fine injector ports. Also, the formation of deposits on the walls is facilitated by the poor quality of the diesel fuel. Clogged injectors can lead to poor fuel delivery, fuel cut-off and engine damage.
The cleaning of the nozzles in a diesel engine is only possible in the conditions of specialized car service stations. В Diesel Centre andWe provide full recycling, partial recycling, repair and overhaul of diesel pumps and nozzles. ПDiesel injector washing - carried out by trained mechanical engineers using modern equipment.
Contamination of diesel injectors - problems
Difficulty starting the engine and idling;
Increased fuel consumption;
The appearance of black exhaust from the exhaust pipe - muffler;
Uneven engine operation;
Increased engine noise;
The appearance of a pungent smell of carbon monoxide;
Decrease in engine power.
One of these problems and in combination should immediately alert the driver. It is best, when these signs appear, to immediately contact a mechanic at an auto repair shop and not use the vehicle until the problem is corrected.
Use the round-the-clock services of roadside assistance of a company Naydenovi auto: Transportation to a service center of your choice - for vehicle inspection and diagnostics. They will take the vehicle to the workshop.
Types of cleaning
There are several options for flushing diesel injectors:
Manual cleaning.
Special fluids are used for its execution. The essence of cleaning is to add fluids to the fuel. The disadvantage of this method is that the deposition of films occurs on the walls of the cylinders. As a result, the heat exchange of the cylinders decreases, the engine overheats. The efficiency of manual cleaning is extremely low and its constant use may result in the need for cylinder repair.
Mechanical cleaning.
Here the addition of liquid is also used, but at the same time the fuel system is connected to a special forced circulation design. The injectors are isolated from the cylinders and thus deposits are prevented from forming on their walls. The efficiency of mechanical cleaning is slightly higher than that of manual cleaning, but also low. Also the disadvantage of the method is the impossibility of checking its results on a diagnostic stand.
Ultrasonic cleaning.
This is the most effective but more expensive and time consuming method of cleaning. In addition to efficiency, the advantage of tray cleaning is the ability to immediately check its results on the diagnostic bench. The essence of the method lies in the use of an ultrasonic bath. It accommodates injectors with connected contacts. At the end of the cleaning cycle, an immediate diagnostic is carried out via these contacts and, depending on the results, the cycle is repeated.
How to slow down injector fouling processes
There are not many real methods to reduce the pollution process. Above all, it is recommended to monitor the quality of the fuelled diesel. Precisely because of the low quality of domestic fuel, nozzles should be cleaned every 20-30 thousand km, while in Europe such cleaning is carried out after a mileage of 120-150 thousand km. km.
The operating mode of the vehicle plays a significant role. Less pollution if lower speeds and frequent braking are not abused. On the contrary, when the vehicle is driven at a speed of about 120 km/h for 10-15 minutes, as a result of creating high pressure in the fuel system, the injectors clean themselves.
Rely on Diesel Service for quality injector recycling and common rail injector repair.
