In the Mercedes C-class model stand line, 4-or 6-cylinder engines.

In the motor block from gray cast iron openings of working cylinders are turned. In the presence on their walls of zadir or рисок they can be chiseled in a specialized workshop. Therefore pistons have to be installed in working cylinders with a tightness. In the bottom of the motor block the bent shaft which is fixed in 5 and 7 bearings of the crankshaft is located. By means of the sliding bearing the rods putting pistons in action are connected with a bent shaft. From below the engine the oil pallet is attached, – in it the engine oil demanded for lubricant and cooling gathers. From above to the motor block the head of cylinders made of aluminum which has good heat conduction and much easier than gray cast iron fastens. The head of cylinders is made by the principle of a cross stream. That is fuel-air mix enters on one party of a head of cylinders while hot gases are pushed out from the opposite side. Thanks to the principle of a cross stream the best gas exchange is carried out. In a head of cylinders there are two camshafts: one for inlet, and another for final valves. Four valves are directly given from a cam-shaft through dish-shaped pushers. Hydraulic dish-shaped pushers provide automatically uniform gap of valves under any service conditions thanks to what adjustment of gaps of valves within servicing is not required.

Lubricant of the engine is provided by the oil pump. It is strengthened ahead on the block of cylinders and is given by means of an additional roller chain. The oil which is sucked in from the oil pallet through openings and channels reaches bearings of the crankshaft and cam-shafts, and also the working surfaces of cylinders.

The pump of cooling liquid at 4-cylinder engines is fixed ahead on the motor block, and at 6-cylinder – sideways the motor block. The pump is given from a ridge maple belt which in addition gives the generator and the pump of steering. Keep in mind that the contour of the cooling system has to be filled annually with fresh mix of antifreeze and anticorrosive means on the basis of the decalcified water.

For preparation of flammable fuel-air mix the operated device of injection and ignition which practically does not demand leaving serves completely electronically.

Уважаемые господа, хочу представить Вам свои размышления на тему корпусной мебели в общественных помещениях. История этого вопроса своими корнями уходит в далекое прошлое, когда еще на существовало общественных сооружений, т.е. в каменный век, возьмем к примеру пещеру, что там являлось мебелью - охапка соломы или невыделанных шкур. Двигаемся по временной лестницы развития человечества и попадаем в примитивные жилища аборигенов Африки крытые пальмовыми листьями и что мы видим опять, в лучшем случае несколько грубо сколоченных деревянных топчанов. И только во времена древней Месопотамии и Египта мы впервые сталкиваемся с развитием строительства общественных сооружений в которых собственно говоря и появилась первая барная стойка (корпусная мебель) представлявшая собой первоначально каменный саркофаг или возвышение в виде стола за которым стоял распорядитель от местного руководства и раздавал подаяние, что предвосхитило появление настоящего, современного бармена который с легкостью фокусника манипулирует тем же подаянием. Таким образом барная стойка появилась не сегодня и не вчера, а более пяти тысяч лет до нашей эры и такой заслуженный возраст дает ей право встать наравне с изобретением колеса. Вот так то господа.
