What are diesel pumps?
Diesel pumps, or so-called Bosch high-pressure fuel pumps are the heart of every diesel engine, and their main task is to inject fuel into the cylinders in a dosed manner and thus start the diesel engine. The diesel pump is an aggregate that, depending on the generation of the injection system, has different functions, but primarily they form the heart of every diesel engine, and their main task is to inject fuel in a dosed manner into the cylinders and thus start the diesel engine. On the oldest injection systems, high pressure pumps had multiple purposes and functions: from determining the injection moment to the amount of injected fuel as well as the injection pressure itself. Repairs of diesel pumps are performed exclusively by professionally trained craftsmen who work in modern workshops for assembly, testing and fault diagnosis.
How and when are diesel pumps repaired?
The repair of diesel pumps is carried out according to a strictly precise procedure in specialized services with the use of the most modern tools and machines. The manufacturer recommends that they be done every 100,000 km, which is profitable in the long run because regular maintenance results in significantly reduced fuel consumption, emission of harmful gases to the environment and better overall operation of the entire engine.
Engineering and maintenance
Repair of diesel pumps Nozzles are another element of exceptional importance for the general quality of engine operation, therefore great attention is paid to their maintenance in specialized services. With state-of-the-art tools handled by professional mechanics, precise tests, adjustments and replacement of cartridges with original parts are carried out. Regular maintenance of the nozzles achieves a fine atomization of the fuel, where each droplet acts as an independent source of ignition.
The most common failures of diesel pumps
Problems with poor sealing of the pump mainly occur in the winter period at low temperatures. The main symptom of this failure is the inability to start the car in the morning at low temperatures. Detecting malfunctions in the mechanics of the high-pressure diesel pump are generally simple and manifest when starting the car. What is characteristic is that the car does not receive gas and emits white smoke from the exhaust. The solution to this problem is to repair the pump and replace all broken parts. As the pump itself has a rather complex electronic system that drives it, electronic failure is a frequent occurrence. The most common problem is with the valve for adjusting the amount of fuel. In this case, the pump itself does not give fuel and it is not possible to start the car. Most of the time, it is necessary to replace the mosfet transistor and the fault will be fixed. Each of these failures is a big problem for the operation of the car itself, because the diesel pump is the heart of the diesel engine. The repair itself is a serious process that requires great expertise, specialized tools and a special work space. Therefore, the repair price is not even a little low. That is why it is necessary to leave the detection of problems as well as the repair of diesel pumps to professionals.
