Heavy fuel: how to save a diesel car in winter
An experienced motorist knows that the saddest outcome for a diesel engine is the outcome of the injection pump. This node is expensive, rarely comes across for sale, and buying a used one is a lottery. That is why the pump needs a special attitude from the driver. Read more on the AutoVzglyad portal.
Few of the contemporaries who have learned how to fill in fuel and anti-freeze and have left car maintenance at the mercy of specialists realize that in a car there are often not one, but two fuel pumps. The one in the fuel tank is a booster, that is, a support, and the top of the hierarchy is occupied by a high-pressure fuel pump - a high-pressure fuel pump. It is installed on gasoline, but more often - on diesel internal combustion engines. After all, a heavy-fuel engine is especially important for accurate dosing and high pressure in the system, which, in fact, are provided by the high-pressure fuel pump.
The diesel line works under monstrous loads, because in the end diesel fuel must get into the cylinders in myriads of tiny drops. Perhaps this is solely due to the pressure, which is created by two pumps.
Moreover, the injection pump must still accurately dose the supply of the fuel-air mixture. The node is complex, loaded, and therefore especially suffering from weather and fuel mischief. You can talk about the plunger pair, and about the camshaft, and about the valves with springs, but we are most interested in the grooves for the fuel supply.
As we know, when the temperature drops below zero, paraffins begin to crystallize in diesel fuel, which in the warm season are simply dissolved in the fuel. The lower the temperature, the thicker the fuel. The first "blow" is taken by the booster pump in the fuel tank - its filter begins to clog, the pump, while maintaining pressure in the system, is forced to work "for wear". The service life of a node is reduced exponentially. However, the resource of the pump is really large, it can survive.
However, it is worth remembering about the high-pressure fuel pump, which, due to its compactness - after all, it is located under the hood, where there has not been much space for 30 years - is equipped with extremely narrow channels, like veins. When paraffin crystals get there, the assembly, which has been working at increased loads from the factory, begins to destroy itself at a triple rate. And this is already costly.
In large cities, the risk of getting into “summer” or off-season diesel fuel is low, but if you go to the suburbs or get into the outback, the chance of running into diesel fuel that is not prepared for frost or, in general, “stove oven” increases significantly. Many will soon go to the south, thanks to the New Year holidays, but after all, winter fuel can not be found there during the day with fire! And then how to go home, you ask?
In order to protect the injection pump from increased load and to prevent the crystallization of paraffins in diesel fuel, it is necessary to pre-fill the tank with a special depressant composition - anti-gel.
For example, anti-gel from ASTROhim allows not only to prevent sticking of paraffins into large lumps, which cause serious damage to fuel equipment, but also to prevent fuel separation.
The composition is made from German Basf raw materials and adapted for our winter and, most importantly, for our fuel. It is added directly to the tank before the next refueling, mixed with fuel and protects the diesel car from the effects of a strong drop in ambient temperature.
By the way, the Astrokhimovsky anti-gel also contains lubricating components that will significantly extend the service life of fuel assemblies and assemblies, including the high-pressure fuel pump. The same high-pressure fuel pump, on which the operation of the fuel system of a diesel car depends.
