The four-cylinder engines installed on Audi 100 cars have the pig-iron block of cylinders with the head of the block cast from an aluminum alloy. In a head of the block the camshaft which is given by a gear belt from a cranked shaft is located. The same belt gives an intermediate shaft which in turn is the drive for the distributor of ignition, oil and fuel pumps.Cranked shaft – steel shod five-basic. Average radical bearings can be with the flanges playing a role of persistent rings or without flanges, but with persistent rings. Pistons are cast from an aluminum alloy with steel inserts. On the piston rings are established two compression and one oil scraper.
Valves are put in action from a camshaft through pushers, and since September, 1985 establish hydraulic pushers. The directing plugs of valves are made of special brass and pressed in a head of the block of cylinders.
The engine is equipped with the gear oil pump installed in a case and a full-line oil filter on the left side of the block of cylinders.
