Why do we want to invest in a car after the renovation?

More and more people are interested in really ancient models of cars. There is no shortage connoisseurs of such cars among the real car fans, but also a person not associated in any way with passion about cars or other vehicles also willing to peek at these cars. The car after renovation will attract the eyes of everyone in the vicinity. There is no doubt that this is a very good way to stand out in the environment around us. Although often these cars are very expensive and driving them is quite uneconomical, you can also treat it as an investment. It is true that we have obtained through this investment a quick profit, but in the long term we really expect lots of money - if not for us, if only for our children and grandchildren.


Gasoline, diesel and gas - what to choose?

Each fuel has its supporters and detractors. Experts automotive industry can give many reasons for allowing the selection of a suitable fuel for our car. However, not always the cheapest solution turns out to be the best for driver or car owner. For example, if you want to consider the option of supplying gas in our car, we must know that it is necessary to install proper installation. This is connected with considerable costs, but on the other hand, avoids the higher fees in the future. However, a group of drivers who decide to change their system already installed in your car, however, is quite sparse.


On its bottom, the sump contains an oil intake

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.
