Motor oil Reduces friction between sliding surfaces, which reduces the wear of the pistons with piston rings and cylinders, bearings and parts of the valve mechanism.

Motor oil is also used for microhermotylation between pistons, piston rings and cylinder walls, as there is always a gap in several microns between these parts. Due to the additional sealing effect of oil resulting from combustion high pressure Gas is transmitted without loss on the bottom of the piston and turns into kinetic energy. Thus, the optimal engine power is achieved.

Another engine oil function is the additional engine cooling. When combustion of fuel, only a quarter of the separated energy can be used to move forward, part of the energy leaves the engine with the exhaust gases, the remaining part of the thermal energy should be discharged with coolant and engine oil. So, for example, the piston can cool only by engine oil. On the one hand, heat from the pistons is transmitted through piston rings and sealing oil with the working surfaces of cylinders, then coolant. On the other hand, the oil sprayed in the crankcase directly cools the pistons. Accordingly, each bearing crankshaft, distribution Vala. etc. cooled by the flow of oil passing through it. Motor oil accumulated heat is transmitted through the walls of the oil pallet by the flowing air flow.

All-season oils

Modern oils are refined from oil with lubricants. But, before refined from the oil, the lubricant will turn into engine oil, oil manufacturers add special additives into it, which at the end of the production process make up to 20% of the oil recipe.

Additives protect oil from oxidation and prevent the formation of foam at high speed of rotation of the engine crankshaft. Some of the most important additives are additives that improve the viscosity index, which are long molecular chains, which, when heated, is swollen and compressed when cooled. These additives act so that the oil is adjusted under temperature mode Engine operation and overlaps several viscosity classes at once. These additives also have a negative property: when high temperatures They lose most of their properties. In addition, water, fuel and residues of combustion products set the limit of the life of the engine oil. Mineral oil is not enough for a long time dominant in engine pressures and temperatures. Therefore, regular oil replacements are not a luxury from which you can refuse, but the necessary standard that provides the normal and long-lasting operation of your engine.

Synthetic oils

Synthetic oils are considered the most expensive, since they partially consist of artificial chemical compounds of carbon, hydrogen and oxygen. In this case, only those molecules that can optimally perform the required lubrication tasks are selected. In practice, this means that these oils are growing much slower compared to mineral oils. They also evaporate slowly and have high long-term stability, it means that the long-term preservation of their original top class Viscosity.

Acquisition of motor oil

Ford recommends Motor oil SAE. 5W-30 (for SAE 10W-40 diesel engine), which correspond to the ASEA ACEA A1-96, B-96 specification or the Ford WSS-M2C912-A1 specification (for the diesel engine ASEA A3-96, B3-96) (,). If you want to use another oil, it must match for gasoline engines quality API Sh (for diesel engines CC MC G5, PD2, API SH). Oils with the designation API SC, SD, SE or SF may even disturb the normal operation of your engine. If the oil corresponds to the criteria given, varieties of oils different manufacturers You can mix each other. You just need to take into account that special qualities of previous recipes can deteriorate over time. Each variety of oil is distinguished by a special recipe additive, the action of which when mixed with other oils can worse. For this reason, it does not benefit also mixing mineral and synthetic oils.

Technical Dictionary

Basic concepts. Oil classification systems

Viscosity.

This is a value for determining oil fluidity. In winter, the engine oil should be so liquid so that after starting the cold engine, it immediately fell to all places of lubricant. On the contrary, in the summer it is necessary to use thick oil so that the oil film does not break at high temperatures.

SAE (Society of Automotive Engineers).

Oil fluidity is indicated by a viscosity class. The relevant classes are established by the American Institute of Automotive Engineers Society (SAE), for example, SAE 5W-30. The less the first number, the easier the oil flows when low temperatures (W - winter). Oil 0W flows at a temperature of -30 ° C, at 5w this indicator increases to -25 ° C, at 15 W - to -15 ° C. The higher the second digit, the better oil resist high temperatures.

ASEA (ASSOCIATION DES Constructeurs Europien Dґautomobiles).

The European norm for oil introduced in 1996, which replaced the SSMS rate. For gasoline engines, there are groups A1 (not containing alcohol-rectitis), A2 (with a minor content of alcohol-rectified) and A3 (energy-saving oil). For diesel engines, oils are divided into groups B1, B2 and B3.

CCMS (Comitte des Constructeurs Dґautomobiles du Marchi Commun).

The specification consists of letters "G" (gasoline) and "PD" (diesel) and numbers. The higher the number, the better quality Oil.

API (American Petroleum Institute).

The specification consists of the letter "s" ( gas engine) or "C" (diesel engine), as well as a subsequent letter. The further located in the alphabet of the letter, the better the quality of the oil.

For this reason, you should not mix clean diesel oils With oils for gasoline engines, in the worst case, you will provoke serious damage to your engine.

Gasoline engines car Fiesta. do not require the use of expensive synthetic oil. Ford recommends using SAE 5W-30 viscosity class oil in our latitudes (see).

Oil consumption

If the engine of your car Fiesta is in excellent technical condition, In the intervals of the prescribed oil replacement intervals, you must simulate a minor amount of oil (0.25-0.5 liters), and no exception and diesel engine. This rule is valid for all engines only if you constantly replace the oil and your engine is not overloaded overly sharp, sports style ride. Any engine consumes some oil. Part of the engine oil burns in the process of engine operation, which is a normal phenomenon. Examine places in the engine, damaged gaskets of the gas distribution mechanism, worn out oil dialing rings, too large gaps between the pistons and the working surfaces of the cylinders or too much gap between the guides and the valve rods increase dramatically normal flow Oil.

Clay exhaust gases of blue color - Exchange of wear

According to the exhaust exhaust gases of blue, you can directly define one of the many engine faults. Even when the oil level remains unchanged, it does not indicate the normal state of the engine: excess fuel and condensed water dilute the oil, which leads to the deterioration of its lubricating properties. This phenomenon is observed primarily in winter and when traveling for short distances - the engine rarely reaches its operating temperatureAnd moisture does not have time to evaporate from the oil. In this case, it is necessary to change the oil through shorter intervals: after 6000 km of run or once every six months.

Classification of light motor (for petrol engines) Oils according to the API in general, it is possible to understand so - with each of the following letter of the alphabet of the oil above.
SG → SH → SJ → SL → SM → SN

35 +30 SAE 5W-30
-30 +35 SAE 5W-40
-25 +30 SAE 10W-30

Engine Nissan QG15DE 1.5 l.

Engine Characteristics Nissan QG15DE

Motor malfunction and repair QG15DE

The Nissan QG15DE engine was developed on the basis of 1.6 liter QG16DE and was called up to replace GA15DE. The cylinder diameter from 76 mm to 73.6 mm was reduced in the QG16DE cylinder block. Accordingly, other pistons were applied, and the compression ratio increased to 9.9. Otherwise, this is the same QG16DE. To reduce the toxicity of the exhaust, the EGR system is used here, the mechanical throttle is also used.

Since 2002, after some update, the motors received a system of changing the phases of gas distribution on the inlet shaft of CVTC, electronic throttle valve And the EGR valve was removed.

The QG15DE motors were equipped with a timing chain, replacement is carried out, approximately every 150 thousand km, sometimes earlier.
QG15DE was not equipped with hydrocomathers, so every 40-50 thousand km need to adjust the valves.

Motor was not too long and for some time, QG15De was removed from under the hips of Nissan cars, and his place was taken by a newer HR15DE.

Problems and Disadvantages of Engines Nissan QG15DE

Motors QG16 and QG18 in their design are similar to QG15, so the problems of their alone are the same: it does not start, high fuel consumption, noise, whistle and so on. Details can be found.

Nissan QG15DE Engine Tuning

Chip tuning

It is best to buy the QG18DE engine and swing it. Tuning 1.5 liter vegetable motor is not the best idea. However, if there is nothing to do, you can buy exhaust system 4-2-1 and make chip tuning. This will give about 10 hp And aggressive sound, the rest is superfluous.
