On the Golf and Jetta set inline four-cylinder four-stroke petrol and diesel engines.
All engines - cast iron block with a block head, cast aluminum alloy. The head of the block pressed guides and valve seats made of steel by sintering. The camshaft located in the cylinder head, driven by a toothed belt. The engine capacity of 1.1 liters and 1.3 camshaft rotates in three bearings and engines of 1.6 and 1.8 liters - five bearings. Piston cast in aluminum alloy with steel inserts in the most loaded areas. Each piston has two compression and one oil ring.
Forged steel connecting rods I-section. At the top head of a rod pressed into the sleeve, which is inserted into the piston pin. At the bottom of the head is mounted thin-walled connecting rod bearings. A rod cover is secured with two screws.
Forged steel crankshaft rotates in five bearings. Main bearing shells, thin-walled, with grooves for lubrication.
The engine mod. NK oil pump is located at the end of the crankshaft. The other engines in volume of 1,1 and 1,3 liter oil pump is installed at the front of the cylinder and is driven by a chain from the engine capacity of 1.6 liters and 1.8 is driven by the intermediate shaft. Full-flow oil filter replacement, is located at the bottom of the cylinder. Engine cooling liquid with a thermostat and expansion tank. The liquid cooling system is circulated under pressure created by a pump of the centrifugal type. The pump is installed in the front of the cylinder and is driven by a toothed belt from the engine 1,1 and 1,3 l or V-belt from the engine 1,6 and 1,8. Aluminum radiator cooling system with plastic tank.
In the power supply system of petrol engines with either triple carburetor or with fuel injection.
