3. Engines3.1. Petrol engine (DB)3.1.1. Introduction
Engine in working volume of 2,2 l
In the Mercedes C-class model stand ryadny, 4-or 6-cylinder engines. In the motor block from gray cast iron openings of working cylinders are turned. At existence on their walls задиров or рисок they can be chiseled in a specialized workshop. Therefore pistons should be established in working cylinders with a tightness. In the bottom of the motor block the cranked shaft which is fixed in 5 and 7 bearings of the crankshaft is located. By means of the sliding bearing the rods putting in action pistons, are connected with cranked shaft. From below the engine the oil pallet is attached, – the engine oil demanded for greasing and cooling gathers to it. From above to the motor block the head of cylinders executed from aluminum which possesses good heatconductivity fastens and it is much easier some gray cast iron. The head of cylinders is made by a principle of a cross-section stream. That is the toplivovozdushny mix enters on one party of a head of cylinders while hot gases are pushed out from the opposite side. Thanks to a principle of a cross-section 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 tarelchaty pushers. Hydraulic tarelchaty pushers provide automatically uniform gap of valves under any service conditions thanks to what adjustment of gaps of valves within servicing is not required. Greasing of the engine is provided by the oil pump. It is strengthened ahead on the block of cylinders and is brought by means of an additional roller chain. Oil sucked in from the oil pallet through openings and channels reaches bearings of the crankshaft and cam-shafts, and also working surfaces of cylinders. The pump of cooling liquid at 4-cylinder engines is fixed ahead on the motor block, and at the 6-cylinder – sideways the motor block. The pump is given from a ridge maple belt which in addition gives the generator and the steering pump. Keep in mind that the contour of system of cooling should be filled annually with a fresh mix of antifreeze and anticorrosive means on the basis of the decalcified water. For preparation of a flammable toplivovozdushny mix the operated device of injection and ignition which practically does not demand leaving serves completely elektronno.
