What additive to pour into diesel in winter
In winter, a diesel engine is harder than a gasoline engine. The reason lies both in diesel fuel, which is poorly pumped at low temperatures, and in the features of the fuel system itself. While in an injection car in winter you only have to drain the fuel from the accumulated water in the tank, a diesel engine requires maintenance.
in order to extend the life of a diesel engine, especially equipped with a common rail system or pump injectors, a number of additives must be used - anti-gels, lubricating additives and cleaners.
In this article, we will consider that when refueling in winter it is recommended to add a diesel car to the tank, why it needs to be done and what means are best suited for the tasks.
What to add to diesel fuel in winter
In the cold season, diesel car owners have to use several additives to extend the life of their fuel equipment. The main problems of a diesel engine in winter:
- fuel thickening;
- increased wear of the fuel system and injection pump due to cold start
- clogged nozzles.
also, a diesel internal combustion engine can start poorly if the battery is dead or the compression has decreased (you have to use the “quick start” tool).
Each of the problems can be eliminated with the help of an additional additive. Therefore, the diesel operator must know what to add to diesel fuel in winter.
Diesel anti-freeze additive in winter
Caring for a diesel engine in winter is especially important. in order for diesel fuel not to freeze in frost, a depressant additive is poured into the tank before refueling. It envelops the paraffin particles and does not allow them to collect in one clot and harden. Such a remedy is added, often in the fall, in case of sudden frosts. In winter, a winter grade of fuel is sold, which already has a lower density and can remain fluid down to -35 ° C. Therefore, its relevance is reduced, but if you are not sure about refueling and at how many degrees a diesel engine can freeze, it is advisable to add such a liquid to the fuel when severe frosts are approaching.
When choosing an antigel, you should also pay attention to the type of composition - ethylene copolymers, polyolefin agents, polymethacrylate and non-polymer additives. Each of them has a certain effect and according to reviews, their effect is also different.
Remedies for increased wear of fuel equipment
When choosing an additive for diesel fuel in winter, you need to take care of the condition of the injection pump and the entire fuel system as a whole. This is due to the fact that winter diesel fuel is more “dry”, and unlike summer, it poorly lubricates the parts of fuel equipment. Therefore, in winter it is recommended to add additives to the diesel fuel, which protect the system from premature wear.
The compositions increase the cetane number and improve the lubricating properties of diesel fuel. If the cetane number is below 45 units (at a rate of 48 units), then the internal combustion engine starts to work hard, knocking. It is necessary to pour a lubricating additive into the tank of a diesel car in winter in order to protect the injection pump and nozzles from friction, as well as to maximize the cetane number to a reference indicator of 51 units - the Euro-5 standard.
Due to the poor lubricating properties of winter diesel fuel, plunger pairs fail faster and nozzles wear out. As a result, the internal combustion engine begins to make more noise during operation, and over time, both the fuel pump and the injectors have to be repaired.
The lubricity rate of diesel fuel (when tested on ball friction machines) at all gas stations is indicated as “no more than 460 microns”. Although in practice it can exceed 500 microns. in order to reduce the contact patch just add lubricating additives. The lower this indicator is, the longer the injectors, injection pump and the entire fuel system as a whole will last.
An example of the lubricity of different diesel fuels: the option on the left (355 microns) is better than the option on the right (425 microns)
In addition, the best additives for diesel fuel in winter extend the life of the particulate filter. This is due to the ability of such funds to improve the combustibility of fuel.
Nozzle cleaning additives
At a negative temperature, the nozzles wear out faster, clog and corrode more due to moisture in the fuel from condensate. There is a spread in performance across the cylinders when one or several nozzles at once do not spray, but pour fuel.
That the injectors are malfunctioning can be understood by the following signs:
- motor troit;
- fuel consumption increases;
- reduced traction;
- too much smoke from the exhaust (accompanied by both a loss of traction and an internal combustion engine tripling).
Cleaning additives remove carbon deposits and deposits in the fuel injectors of a diesel engine, restore their throughput and equalize the pressure in the system to passport indicators. The main advantage of the product is that this diesel additive in winter washes not only nozzles, but also other components of the fuel system.
Having dealt with the main problems of a diesel car, what is better to add to diesel fuel in winter should be decided by each car owner individually based on the task. But, in order to choose a good and effective additive, it is worth studying the reviews, tests and reading the instructions for the product.
Rating of Russian additives for diesel in winter
The complexity of choosing a diesel additive lies in the wide range and number of manufacturers. But it is necessary to use diesel anti-gel in winter, like no other means, in order to avoid the risk of being on the highway with a stalled car due to waxing of the fuel and the entire system. It is impossible to be completely sure that you fill in winter fuel at unfamiliar gas stations. in order to help buy a working tool without overpaying too much, we have compiled the TOP additives for diesel fuel in winter.
Available anti-gels so that diesel does not freeze in winter
The working composition is similar for almost all such products, but due to the concentration of other additional additives, antigel manufacturers achieve better properties. Therefore, we recommend that you select, focusing on cost, the required volume and the purpose for which you are going to use the additive from freezing fuel in cold weather.
RUSEFF Diesel Fuel Antigel
Antigel RUSEFF for diesel fuel is sold in different packages, the most popular (for passenger cars) 270 ml under the article 19309N for 50 liters. fuel, but there is also a can for 120 liters of fuel and a canister for trucks, its volume is designed for 500 liters of diesel fuel.
