Engines 2C and 2C-T in-line 4-cylinder, 8-valve with an overhead camshaft Engine displacement 2.0 liters. Cylinder numbering is from the crankshaft pulley.
Engine running order: 1-3-4-2.
Crankshaft 5-support with 8 counterweights. mounted on the continuation of the cheeks of the crankshaft, designed to unload the main bearings from the action of centrifugal forces. Holes are made in the crankshaft for supplying oil to the main and connecting rod bearings and other elements.
cylinder head made of aluminum alloy.
Exhaust and intake valve springs are made of special carbon steel and have a belt pitch to help reduce the chance of resonance.
Camshafts
The camshaft is driven from the crankshaft by a toothed belt.
The camshafts have 5 bearing journals. Lubrication of the necks, cams and gears of the camshaft drive is carried out with oil, which enters through the oil channel located in the center of the shaft.
The clearance in the valve drive is adjusted by replacing the shims in the valve lifters. The shims can be replaced without removing the camshafts.
Pistons made of aluminum alloy.
piston pins - "floating" type:
Compression rings: the upper compression ring is made of stainless steel, the lower compression ring is made of cast iron.
Oil scraper ring consists of two scrapers and an expander. The oil scraper ring removes excess oil from the cylinder walls, preventing it from entering the combustion chamber.
Cylinder block cast iron. The upper part of the cylinder block is covered by the cylinder head, and the lower part of the block forms the engine crankcase, in which the crankshaft is installed. The cylinder block has a cooling jacket through which coolant circulates.
oil pan bolted to the cylinder block. The oil pan is stamped from steel sheet. The dividing wall inside the oil pan holds enough oil even when the vehicle is tilted. The baffle plate also prevents the creation of oil surges when the vehicle is braked hard.
