What kind of oil is recommended to fill in the diesel generators?

Different engine models require the use of engine oils with different properties. For generators select the type of oil should be taking into account the type used in these fuel (petrol or diesel), and the engine operating conditions. In this article we consider the features of diesel power plants, and oil, which is recommended in order to make it work properly and without interruption.

Why diesel generators need special engine oil?

At the time of the diesel engine is running there is a large thermal stress and produces a lot of smoke, soot and various oxides-that they differ from gasoline engines. It is also important to consider the fact that due to the high pressure which arises in the combustion chamber is accelerated oil oxidation and considerably faster aging. When the engine is running at high speed, the diesel oils are prone to the formation of soot (ash).

With all this diesel generators need special engine oil with good emergency. It is usually added to bind strongly alkaline additives that can break down even fairly solid deposits. These oils are also added special ingredients to neutralize oxidation products. The oils for gasoline engines priorities are very different properties: a strong oil film and lowest burnout.

In order to understand what kind of oil to buy diesel generators, please note the following recommendations made:

  • The whole Diesel fuel, no residue, does not burn, on the contrary a large amount of soot produced by the combustion.
  • In operation, this type of engine oil properties change starts, so-called process «aging» (Pollution particulate debris, combustion products, impurities, water and the like. D.). Also, useful additive gradually picks up and lose their effectiveness. And note that more than a worn engine, the faster it will grow old oil.
  • To ensure long-term operation of the diesel generator, it is recommended to use oil with a high content of alkaline, detergent and dispersant additives.
  • The oil must also ensure a proper level of protection of various engine parts which are exposed during operation to mechanical wear. That is, it should provide a strong oil film that can endure high mechanical loads without loss of its lubricating properties.

How to choose oil for diesel power?

When purchasing motor oil for diesel should be oriented to the following factors:

  • composition;
  • viscosity index;
  • labeling;
  • class.

Let's look at these options in greater detail

    • Composition. In its composition, the oil is of three basic types: synthetic, semi-synthetic and mineral. They differ in some original raw materials used for their production, as well as a set of additives that affect their performance. As for the features of the operation, the experts recommend at zero temperature in the summer, use mainly mineral compounds. And, as the sub-zero temperatures in the winter, so the oil can crystallize that will prevent the engine from starting, it is better to change the oil on a synthetic, which is suitable for use in cold weather
    • Viscosity. With regard to this parameter, the figure is higher than this, the better the oil will protect engine parts from mechanical wear by friction. However, a very dense composition may have difficulty with penetration into the gaps between the motor elements, that will hamper the work. Do not forget that the density is also dependent on the operating temperature, the colder outside, the oil is thick.
    • Marking. All motor oils are labeled by type, class and type of engine. If you see the letter S, then this structure is recommended for petrol engines and the letter C for diesel ─. Sometimes the producer wrote just two letters (S/C), which means that before you a versatile compound that is suitable for both types of engines. The letter, which comes next, is the recommended operating conditions. Use diesel generators can be oil from the CD label, CE, CF-4. If the second labeling are the letters A, B, C, then this oil is not suitable, as it is considered poor lubrication low-class.

This table shows only the general approach to the choice of oil. Usually all manufacturers indicate on the label in great detail all the properties and characteristics of their lubricants and additives used in them. All this should be taken into account, as much depends on the time and temperature operating hours of the alleged continuous operation, deterioration of engine parts, etc.

What kind of oil is recommended to fill in the diesel generators?

It is said that any strict requirements for the type of oil poured into the engine no. Mineral compositions are relatively inexpensive, and if in terms of viscosity and the class they are suitable for you, they are safe to take. It is believed that today's diesel generators is necessary to use only synthetic, but it is untenable. At concurrence of all the necessary requirements of this oil can easily provide a stable operation of the motor until the next service. However, synthetic and semi-synthetics have several advantages, in particular, they protect the motor more effectively provide stable characteristics work better at low temperatures and have a smaller flow rate, as compared with mineral compounds. Therefore, the most appropriate is to use diesel plants semi synthetic oils, which is to choose the ratio of «quality/price».

Generator set maintenance and oil change

One of the most significant moments in the operation of diesel-electric generators is to comply with the established frequency of lubrication.

The first oil change should be carried out after 20 hours of operation of the machine. At this time it is not recommended loading the generator to complete. This step is important so that all parts of the motor have to get used to each other. Further, oil change takes place on the following schedule:

  • Synthetic-after 100 hours of work;
  • mineral-over 50 hours
  • .

Procedure when changing the oil shall be as follows:

  • heat the generator;
  • Spotless the drain plug;
  • Take special container for draining waste oil;
  • remove the cap and carefully pour from the generator into the prepared container waste oil;
  • Fill in new oil;
  • close the oil plug.
