Gas engine (8 valves) cutaway
The engine is a four-stroke, four-cylinder, in-line with a transverse arrangement in front of the car. Engines with a displacement of 1905 cm33 and 1998 cm3 with 16 valves have two overhead camshafts. On all models, the water pump drives the timing belt.
Lubrication - under pressure, created by an oil pump, which is driven by a chain from the right end of the crankshaft. Models with 16 valves have an oil cooler that is mounted below the oil filter.
The engine code is stamped on a plate attached to the right front of the engine block on a 1761cc engine3 embossed directly on the front side of the cylinder block, and on the engine 1998 cm3 - to the left of the oil filter.
