The engine is an air-cooled, six~cylinder, four-cycle flat six Otto engine. The crankshaft is mounted in 8 bearings of the ~part light metal alloy crankcase. Three single cylinders are horizontally arranged at the right and left of the crankcase. The ovenhead valves are installed in V-shape in each cylinder head . are controlled by an overhead camshaft . The rocker arms andthe two camshafts are each mounted in a common camshaft housing for three cylinders . Both camshafts are driven by chains from the crankshaft via an intermediate shaft . On the cylinder heads a triple down-draft carburetor with the pertinent intake pipes is provided for each cylinder bank. The engine and the transmissíon are mounted together . The unit is installed at the rear of the vehicle with the engine in front of the transmission (mid-engine design) two They

COOLING

Cooling is by means of an axial blower; consisting of an impeller and the blower The center of the blower housing holds the support for the alternator; the impeller with the V-belt pulley is attached at its shaft end The hub and the outer of the blower are connected to each other by means of four supporting vanes _ The blower housing is positioned in the body of the crankcase by means of a set pin and held in position by a clamp. The blower delivers the air required for cooling the engine, the oil cooler, the alternator; as well as the fresh air for the of the car. The air flows through the upper plastics-molded air guides to the cylinders and to the cylinder heads . Baffle plates provide for uniform distribution of the A duct incorporated into the upper air leads the air flow directly to the oil cooler_ The connection for the fresh air delivery to the heat exchangers is on both sides of the blower housing . ring housing heating system cooling cooling guide housing .

OIL CIRCUIT

The engine is lubricated by dry with forced circulation by means of geared pump driven by the intermediate shaft. The gear pump is divided into a pressure pump and larger suction pump _ The oil is filtered through an oil strainer, which is accessible from below and pumped to an oil tank attachedtothe body ~ The pressure pump will take the oil from there and supply the lubricating points . When the oil is cold, it is taken directly to the points, when it is hot, it is first taken through the oil cooler under the control of a thermostat . The changeover temperature is at approx _ 80%c The oil cooler
