Employment in the automotive industry

Jobs in companies related to the automotive industry is a dream for many people interested in this subject outside working hours. By the way, the combination of working with passion can be very desirable in many cases because it makes the work simply better. Where to find work in the industry? The possibilities are really a lot. Starting from corporate stores selling car straight from the factory, production, and ending with the consignment of used cars person interested in such work will certainly find a place for themselves. True, the requirements for work on some of the positions are quite high, but having the necessary qualifications for sure we have a chance of winning the coveted job.

Public transport is of utmost importance. You can quickly reach the first place, above all those who do not own a car. On the other hand, using the bus or smaller buses can get rid of the problem of parking the, which is often quite confusing for drivers. The bus ride makes it not need to be focused on driving. It is not surprising that this mode of transport is still often used on Polish roads. True, much of the buses is a machine that would give longer to the museum associated with the automotive industry, but there is also a really modern, rich in many of the features of vehicles on the road. The use of the exclusive bus is a feature of organized tours and I must admit that this is undoubtedly advantage of long journeys.

A single main bearing

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.
