KAMAZ engine has many complex parts and assemblies. But the most difficult unit is such a spare part as a high-pressure fuel pump. KAMAZ must be equipped with this pump. It doesn’t matter what kind of modification and load capacity it has - the pump is on all models without exception. This unit is distinguished by its complex design and functionality. It is simply irreplaceable in the fuel supply system, therefore it is not worth repairing it yourself, it is better to entrust this work to professionals. KAMAZ fuel injection pump ( high-pressure fuel pump ), although it has high reliability, sooner or later every part requires replacement and repair. In this article, we will consider cases in which the replacement of this unit is required, and also find out how it functions.
TNVD device (KAMAZ) and its replacement
Replacing this spare part is a complex technical process that requires certain knowledge, skills and efforts. Not in last place is the availability of special equipment, without which the replacement or adjustment of the KAMAZ fuel injection pump is simply impossible. It is also worth noting that the KAMAZ high-pressure pump plays a crucial role in the supply of diesel fuel through the fuel line. If it does not work, the engine will also stall, and it will simply be impossible to start the car. And contaminated nozzles contribute to breakage, accidental ingress of dust and other small particles into the inside. But water is the main enemy for KAMAZ fuel injection pumps. If this liquid enters the pump device, all its work immediately ceases, and repair can not be dispensed with here. The only thing that can save the situation is a complete replacement of the pump, and it is also carried out at a specialized service station.
How can I extend the life of the fuel system?
In order for the pump to last as long as possible, it is enough just not to save on the diagnosis of fuel lines, as well as to make timely cleaning or replacement of nozzles. In the case of severe pollution (as a rule, this is detected after diagnosis), it is imperative to clean the entire fuel system, otherwise a breakdown of the KAMAZ fuel injection pump is inevitable.
How can I find out about a pump malfunction?
Of course, the high-pressure fuel pump itself will not tell you about the breakdown, so you need to be guided by certain rules by which you can understand how much time the pump has to "live" and whether it is time to send it for diagnosis. So, let's look at the main signs that indicate the malfunction of this unit:
- The first thing that drivers notice is a significant reduction in engine power. KAMAZ is already weak, especially when it is overloaded, but when it becomes generally “frail”, this is the very “bell” that indicates a fuel system malfunction.
- Starting the engine with problems. If the engine does not want to work when turning the ignition key, it means that it is time to go to the diagnostics.
- Fuel consumption. This, of course, is the whole story - many drivers often criticize even serviceable KAMAZ for such a high consumption (about 40 liters of diesel fuel with a load of 15 tons), but if the mark goes even higher, be aware that the problem is in the pump.
- And the last sign is the black smoke from the exhaust pipe.
Knowing these signs, you will always be aware of when you need to seek help from specialists and, if necessary, repair the fuel system.
