Pic. 1.1. Engine 1.8 (18E).
The crankshaft rests on 5 main bearings. To control the axial movement of the crankshaft, thrust washers are installed on both sides of the central main bearing.
Pic. 1.2. Engine 1.8 (18E).
The connecting rods are attached to the crankshaft through connecting rod bearings that are split in a horizontal plane. The connecting rods are attached to the pistons by piston pins, which have a fixed fit in the connecting rods. Aluminum alloy pistons are equipped with 3 piston rings: two compression rings and one oil scraper ring.
The camshaft is driven from the crankshaft by a composite rubber timing belt. The movement of the valves is controlled by rockers, which are supported at their rotating end on self-adjusting hydraulic pushers (That. no valve clearance adjustment required). The intake and exhaust valves move in guide bushings pressed into the cylinder head.
The engine is lubricated using a gear pump located in the front of the cylinder block. The oil pump is driven by the crankshaft, while the fuel pump (on carburetor models) and the distributor are controlled by the camshaft.
