General information about engines 1.5/1.6/1.8 l

This chapter covers large displacement engines: 1457 cc³, 1471 cm³, 1588 cm³ and 1781 cm³. Basically, these engines are the same, the difference in displacement is achieved by changing the diameter of the cylinders and the piston stroke.

The engine camshaft is located above the cylinder head (HE IS WITH). The camshaft is driven by a toothed belt from the crankshaft.

The crankshaft rotates in five main bearings; the middle main bearing is thrust. The oil pump is installed in the lower part of the crankcase and has a common drive with the ignition distributor from the auxiliary shaft. The fuel pump on carburetor engines is also driven from the auxiliary shaft eccentric and is located near the ignition distributor and oil filter base. The auxiliary shaft is driven by a camshaft toothed belt.

The cooling pump is located on the side of the cylinder block and is driven together with the generator by a common V-belt.

The intake and exhaust manifolds are located on the same side of the cylinder head.

The camshaft rotates in five bearings and acts on the valves through plunger-type pushers, the thermal clearances of the valves are adjusted using shims of various thicknesses.

Most repairs, such as removing the timing belt, cylinder head, or coolant pump, are performed without removing the engine from the vehicle. Removing the engine is only necessary for major engine repairs. After cleaning and disassembling the engine, check the clearances of the crankshaft bearings, as well as pistons, rings and cylinders, as described earlier (see chapter "Engine 1.0/1.3").
