Features of the operation of diesel engines in winter are due to the presence of frost, in which the fuel has a fairly capriciously behave, as a result of which malfunctions are happening with some elements. The fact is that at low temperatures, the diesel fuel is very adversely affecting the fuel equipment and the engine itself, because it is thick. About this further in the article.

Diesel engine in winter, features of operation

The main advantage of the diesel engine is its fuel efficiency, which is carried out due to a sufficiently high pressure in the combustion chamber, which is absent in the gasoline motor, where ignition is due to the supply of sparks using a spark plug. Another difference between these engines is that the air to the gasoline power unit is supplied separately from the fuel. The air-fuel mixture falls into diesel. In addition, diesel engines are more durable. The high torque generating the motor allows the car to work in the most difficult conditions. It is as a result of this diesel applied on SUVs and trucks.

The main disadvantage of all cars on diesel - they need the correct operation of the diesel power unit, since it is extremely capricious and presents high fuel requirements, especially in winter. Paraffin is present in diesel. With the plus temperatures, this does not affect the operation of the car, however, when the cold come, the fuel is nervous, and the filters begin to be clogged with paraffin threads. As a result, the vehicle does not turn out.

how to start a diesel engine

There are a lot of reasons for the difficult launch of a diesel engine in winter. To start a diesel engine, a powerful battery is required, and the real capacity of the battery in the cold decreases, with the result that in the morning it can no longer provide the necessary value of the start current. In order to avoid this, the battery is desirable for the night to be removed from the car and enter the warm room.

If this opportunity does not have any efforts do not bring due results, you can use the second car, connecting the terminals of its battery with the terminals of its battery. Additionally, you can warm the battery, while turning on the headlights. Heating cupcakes can also help with launch. To do this, turn on the ignition two or three times ten seconds.

If the motor does not start, it is desirable to warm the vehicle in a heated room. But, if there is no such possibility, you can use boiling water or a soldering lamp for heating, however, this method is not quite safe, although it is able to bring a quick result. To avoid accidents, it is necessary to observe the limit accuracy.

heating diesel engine in winter

To answer the question, how much time and how to warm the diesel engine at idle in winter should take into account the specifics of the engines of this type. First of all, the diesel engine has a high efficiency, at idle turns such an engine in the cold warm it is quite difficult. The second nuance is that the operation of the engine at idle (minimum revolutions) indicates a low oil pressure in the lubricant motor system and refers to complex operating conditions.

Consequently, the most optimal option is heating from five to ten minutes, depending on the outer air temperature. During this period of time, the coolant is heated to 40-50 degrees Celsius, the oil is diluted, the parts are heated, the fuel is fully combined in the cylinders.

After such a warm-up, it is smoothly starting to move on low revs and reduced transmission. In warmth, there will be quite no more than 1-2 minutes of heating the diesel engine before the trip, and when driving the engine completely and quickly warms up.

what oil to fill in the diesel engine in winter

First of all, it is necessary to pay attention to the quality and condition of the engine oil. It is necessary to pour only oils recommended by the manufacturer, and it is necessary to do this as often as possible, for example, every eight-nine thousand kilometers. In winter, it is desirable to pour into the engine only those oils that are designed to operate the diesel power unit in winter. There are small tricks to run a motor in winter. For example, that the oil does not go through, add a small glass of gasoline into it. Then his consistency will become more liquid, and the motor will be launched much easier.

winter diesel fuel

In winter, a special winter diesel fuel should be poured.

Already at a temperature, five degrees should be changed to the fuel to the winter. And when the temperature is less -25 degrees Celsius, you need another type of winter fuel - arctic. Some car owners are trying to save and pour summer fuel. But, so the savings are carried out only at the expense of its purchase, however, there are spending on the subsequent repair of the motor.

diesel fuel additives

Adding additives into diesel fuel has long been the usual phenomenon for modern motorists, because its quality at our refueling leaves much to be desired. Of course, the modern market offers a huge assortment of additives for diesel gasoline, in principle, like any other automotive chemistry. There are certain variations of additives that have something else appointment:

1. Complex additives that increase the cetane number cleansing the injection system that do not allow foaming of fuel and acting as anti-corrosion additives.
2. The so-called "antigels" preventing the freezing of fuel in winter at temperatures as well as 47 degrees.
   
3. Additives, cleaning motor nozzles and plunger pairs in high pressure fuel pump.
4. Additives that do not allow moisture to crystallize in the fuel system of the vehicle.
5. Tuning additives.
6. Additives to reduce the smoke of the motor and so on.

How to insulate diesel engine for the winter

To insulate a diesel engine for winter, you will need the following materials and tools:

1. Sharp scissors.
2. Stationery stapler.
3. Corrugated polyethylene.
4. Special tool for working with silicone.

The first thing to be done is to cover the motor with something warm. Although in case of severe frosts, this event will not help. Of course, it will give its favor, but ineffective. To warm the diesel engine qualitatively, you need to put a car on the observation pit. Next, we carry out the insulation of the pipeline, which will make it possible to prevent cooling of fuel. It is best for these purposes foam corrugated polyethylene, which has a thickness of five millimeters.

So that the insulation goes correctly, measure for starting the circle of the tube and with the help of scissors cut the necessary band from polyethylene. Next, it is necessary to bite the pipeline with this strip and fix with a stapler. The tube has a peculiar tail, which must be started at eyeliner to the brakes and secure the sealant.

Autonomous Preheater, Views

By type of device, autonomous prehea heaters are air and liquid. Airborne devices - buses, trucks, special equipment and sea vessels, and liquid heaters are used on passenger cars. Air heaters have large dimensions, rather than liquid, consume more fuel and, accordingly, produce more heat.

Liquid preheaters are divided into several variations, which can be conventionally indicated as follows:

A - for compact cars.

B - for universal cars.

B - for SUVs and minivans.

Useful advice

Do not forget about the heating of the car, which will help save the diesel motor a long life. In addition, do not start the car from the pusher and do not allow towing, otherwise there is a possibility to break the timing belt, as well as shift the gas distribution phase.
