Engine oil with the turbine: types, how to choose

Stable motor operation provides not every composition. The full potential of the vehicle revealed only with proper selection.

Features

The use of a turbocharger - the main difference from conventional diesel turbo. In diesel engines the pistons are moving due to ignite the mixture of air and fuel. It then uses the exhaust energy, the impeller of the compressor and turbine also driven.

The turbine is integrated into the construction, responsible for feeding air cylinder. It makes it so that the air force is inside, while maintaining a high pressure.

Through this process, the diesel engine power is increased by 25 percent. It can be made larger by setting the device or intercooler for cooling the air.

Inside the structure there are high thermal stress. A large amount of soot is produced due to combustion products. Because of the high pressure working fluid is oxidized. Hence, it is aging faster.

How to choose the oil for the turbine engine

Wear parts leads to the fact that foreign particles enter the fluid. Diesel fuel because it burns with a high percentage of sulfur. Inside the design water flows. Engine durability will provide only part of preserving the properties in all conditions. To do this, add the additive.

Repellent should be on performance in the instructions. Noteworthy viscosity SAE, which requires a particular vehicle. Quality classification as subject to this rule.

Formulations were separated into groups of several classifications.

• ILSAC - developed by Asians.
• ACEA - the European quality standards.
• API-developed by Americans.

API classification on the label indicate more often. Well, if the manufacturer in the service book indicates what level of viscosity requires a particular vehicle. These data will be enough to store staff to find a suitable liquid.

In the service book, in some cases, and indicated the exact name of the manufacturer.

Classification by API:

1. CF-4. Toughened requirements for toxicity, improved characteristics.
2. CG For cars built after '94.
3. CF-4. Chetyrohtaktnyeturbodizeli created after '90.
4. CE - diesel engines with high supercharging, 1983 release and later.

Classification ACEA:

• E3-96. For fluids that are used in industrial and commercial vehicles, which boost big enough. Suitable for use in harsh conditions.
• E2-96. Improved properties, compared to E1-96.
• E1-96. Suitable for industrial and commercial vehicles with high pressure mode. Used heavy class Standard conditions.
• B3-96. Diesel cars with and without turbocharging.
• B2-96. Only for diesel engines with turbocharging.

Book may be absent from used cars. Or those who have lost. Then the information without any problems will be found on the official website of machine manufacturers or oils.

The difference between the semi-synthetics and synthetics, mineral oils, no. The main difference - in principle oil production. This is reflected in some of the characteristics and cost. Synthetic oils are widely used, although they are more expensive.

The mineral used in engines that are exposed to an average load. Optimally apply compositions on cars manufactured in Russia.

There are universal compounds. Poured in gasoline and diesel engines. The first letters of the marking point to the destination.

For the upper class are SG oil.

Types of oils for turbine engines with

Synthetic can be used even at high altitudes, where the operating temperature reaches -50 degrees. For automotive vehicles such compositions are actively used, since the 60s of the last century.

The difference between mineral water and synthetics lies in the unusual viscosity-temperature qualities.

In internal combustion engines the fluid is required, which in different modes of operation would not change its properties. By the ideal response nearer synthetics.

At low temperatures multigrade oils least viscous. This means that no problems with starting the engine at the same low temperatures.

The oil layer acquires bearing capacity oily base with differing high viscosity at temperatures above 100 degrees.

In season types thickening additives are introduced to the viscosity at certain temperatures is sufficient. However, thermal and mechanical stress on the fluid leads to the destruction of the additives. Viscosity is reduced during further operation.

Viscosity synthetic less dependent on temperature than that of the mineral. Because it allowed not to introduce an additive, or to use their minimum amount. This is another advantage, which is different synthetics.

Exploitation

Compliance with operating conditions of the unit - an important requirement for oil. Well, when the match is complete, but is allowed in part. Even if the requirements are advised to avoid prolonged operation of the internal combustion engine at high speed HF.

The oily base is oxidized, if it are high temperature. This leads to oxidation and thermal degradation. Because of this, the viscosity engine oil increases. On details of engine deposits appear. Pistons and rings are affected in such a situation.

Zakokosovka - a phenomenon that is familiar to every second or third driver. This is a situation where the oil is burned, consumed in large quantities.

Engines with fluids suffer from short trips, during which high speed is maintained. Time work at normal temperatures is not enough, which is why the engine cools down. This leads to the formation of condensate, deteriorating performance.

All-season - it is better in a stable climate, without severe frosts and extreme heat. If the temperature is extremely low - use the winter oil. This also applies to summer.

The average mileage on one tank filling is not more than 10 thousand kilometers, but each manufacturer sets deadlines separately. The composition is contaminated, if not to conduct timely replacement. Formed heat engine operates with an increased friction.

Replacement interval - notional figure. Calculated based on good and heavy operating conditions. Synthetics, semi-synthetics and mineral water are changed at different intervals, the difference amounts to 2 thousand kilometers.

Synthetic oils - the most resistant to aggressive influences.

Oil change becomes necessary when:

1. Occurs suspension with solid particles in the oil phase.
2. Loss of ability to lubrication. Because of what parts are working for wear. This will tell the characteristic sounds, reaching from the engine compartment.

engine flushing carried out not at the moment when the liquid darkened and inside parts were covered with mud. Dark liquid - a good sign.

Worse, when it is still fresh and colorless after a few thousand kilometers. This indicates the presence of deposits, which will not get rid once.

Ashless dispersants - additives that are used in automotive oils. Ashless mean that there are no connections metals. Dispersants - a word that speaks of grinding dirt, their dispersion.

During operation, the fluid is contaminated:

1. Because of the entry of foreign particles from the outside.
2. When oxidation occurs, leading to the formation of insoluble particles.

Dispersants solve the problem of retention of contaminants in the oil in a finely divided state. They do not give sleep deposits in the form of precipitation. Otherwise grid in maslopriomnika clogged. Substances able to wash the engine and what is inside.

Liquid inside the engine is mixed with the air or operates as films. This means that contact with air occurs constantly. Oxidative processes occur. But oxygen and temperature are not the only reasons for it.

combustion products, already a part of the oxides also contribute their share. The antioxidant additive is introduced into the composition in order to slow down this process. They are needed for the decomposition of primary oxidation products. Free radicals under the influence of their transition to a stable state.

oil viscosity increases as the operation without antioxidant additives. Increased consumption of the working fluid - minimal impact. Her performance is lost. Poor are starting properties.

A number of additives and is responsible for its ability to resist wear and protect it from other items. It is important for couples involved in friction. They work in elastohydrodynamic lubrication mode, in case of high specific pressures on the part surfaces.

One solution - to chemically modify the surface subjected to friction. Modified layers are then interact with each other.

Factors influencing the choice of anti-wear additives:

1. The stability of the hydrolytic type.
2. Saving of thermal performance.
3. Interaction with colored alloys corrosion level
4. The stability of the lubricating properties, the influence on them.

It is important to distinguish from friction modifiers antiwear additives. Name antifriction received a number of modifiers that reduce friction. They operate under elastohydrodynamic, boundary lubrication. Although both of these functions are combined in some modifiers.

A number of additives is introduced for the protection of ferrous and nonferrous metal inside the engine. Alternatively, the protective film is formed or neutralized the effect of active substances affecting the surface. Fastening associated with physical absorption.

Without chemical interaction can not do. Lead and copper layers also formed additives. The main requirement - the ability to maintain the properties to the effects of dispersants and detergents. Energy saving oil with friction modifiers are often combined.
