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.

Driving license for bus drivers

Buses are one of the most important means of communication. Thanks to them we can quickly get to a certain place without thinking about parking and so on. To become a bus driver it is necessary to invest in a special driver's license. Although at this rate it differs significantly from the "normal" driving license, license for driving cars, if only because of the size of the vehicle, which we, however, provides a number of people interesting experiences. Driving license this category is much less common than the traditional license category B, so that we can greatly increase your chances for example in the labor market, when put in their application documents mention of such a document.

Alcohol and driving is

Driving after drinking can be dangerous even when guided bike. In the case of more complex machines, allowing to achieve a much higher speed, directing them under the influence of alcohol can be fatal. Despite the many social campaigns regarding the prohibition of driving under the influence of alcohol and strengthen penalties for drunk drivers, unfortunately, many of them still do not apply to this rule. Meanwhile, the management of a car under the influence of alcohol can lead to death of not only the driver and passengers, but also to the disappearance of completely innocent people, not even staying on the road during this event. Getting into the car under the influence of alcohol we create unnecessary risk.
