Lovers of fast driving

best oil for DaciaWhile many people mistakenly believe that the pirates road only directing the car passenger or a motorcycle, more often unfortunately, can be seen that also other vehicles moving at extremely high speeds, especially on highways that are a little better than the standard highway .

Many speeders, not at all applicable to the rules of the road that drivers of large trucks.

They often mistakenly believe that the bigger the car on the road, the greater is the priority in traffic and forcing the other participants in the traffic, which can have very dangerous consequences. Going on a long trip, it must therefore be very careful with this kind of riding companions.

A single main bearing

best oil for Dacia
On its bottom, the sump contains an oil intake covered by a mesh filter which is connected to an oil pump then to an oil filter outside the crankcase, from there it is diverted to the crankshaft main bearings and valve train.

The crankcase contains at least one oil gallery (a conduit inside a crankcase wall) to which oil is introduced from the oil filter.

The main bearings contain a groove through all or half its circumference; the oil enters to these grooves from channels connected to the oil gallery.

The crankshaft has drillings which take oil from these grooves and deliver it to the big end bearings.

All big end bearings are lubricated this way.

A single main bearing may provide oil for 0, 1 or 2 big end bearings.

A similar system may be used to lubricate the piston, its gudgeon pin and the small end of its connecting rod; in this system, the connecting rod big end has a groove around the crankshaft and a drilling connected to the groove which distributes oil from there to the bottom of the piston and from then to the cylinder. Other systems are also used to lubricate the cylinder and piston.

The connecting rod may have a nozzle to throw an oil jet to the cylinder and bottom of the piston.

That nozzle is in movement relative to the cylinder it lubricates, but always pointed towards it or the corresponding piston. Typically a forced lubrication systems have a lubricant flow higher than what is required to lubricate satisfactorily, in order to assist with cooling.

Specifically, the lubricant system helps to move heat from the hot engine parts to the cooling liquid (in water-cooled engines) or fins (in air-cooled engines) which then transfer it to the environment.
The lubricant must be designed to be chemically stable and maintain suitable viscosities within the temperature range it encounters in the engine.Źródło: https://en.wikipedia.org/wiki/Internal_combustion_engine

Surfaces in contact and relative motion

Lubrication Diagram of an engine using pressurized lubrication Wikimedia Commons has media related to Internal combustion piston engine lubrication systems. Surfaces in contact and relative motion to other surfaces require lubrication to reduce wear, noise and increase efficiency by reducing the power wasting in overcoming friction, or to make the mechanism work at all.
At the very least, an engine requires lubrication in the following parts: Between pistons and cylinders Small bearings Big end bearings Main bearings Valve gear (The following elements may not be present): Tappets Rocker arms Pushrods Timing chain or gears.

Toothed belts do not require lubrication. Źródło: https://en.wikipedia.org/wiki/Internal_combustion_engine.
