The car is equipped with K4J and K7J engines - gasoline, four-cylinder, four-stroke, in-line, with an overhead arrangement of two camshafts. It is placed in the front part of the car across its longitudinal axis.
The camshafts are mounted on six support bearings. The camshafts are driven from the crankshaft pulley by a toothed rubber belt, which also drives the water pump. The engine uses a closed crankcase ventilation system. The gear-type oil pump is driven by a chain from the crankshaft.
