Delco electric generator used for charging the battery of the 

 car. The generator is also the starter motor. The starter 

 pedal mechanically engages the starter gear with a large 

 ring gear on the flywheel at the rear of the engine, and closes 

 the starter switch. When the engine was running, the unit 

 acted as a generator. 



Engine lubrication was by both force feed and splash. 

 The crankshaft is drilled for the passage of oil to the bear- 

 ings from a gear oil pump at the bottom front of the engine. 

 The oil capacity of the crankcase is 6 quarts. A removable 

 aluminum oil pan is bolted to the bottom of the crankcase 

 for access to the lower interior of the engine. 



A constant-level, float carburetor is connected to an in- 

 take manifold, which branches off to both cylinder blocks. 

 Gasoline from the 20-gallon tank at the rear of the car was 

 forced to the carburetor by air pressure in the tank. This 

 pressure was maintained by a small air compressor driven 

 by the engine. With the engine at rest, and pressure down 

 in the tank, a hand pump on the instrument panel board 

 was used to establish the initial pressure. 



The intake manifold was heated by the exhaust gases 

 passing through a jacket on the manifold. Each block has 

 its own exhaust manifold, and an individual muffler in the 

 center of the car. 



The engine is water-cooled, with a water pump for each 

 block. The pumps, located at the lower front of the en- 

 gine, are driven by the timing chain. A vertically mounted, 

 tubular radiator is at the front of the chassis with a fan, 

 driven by the timing chain, located behind it. The capac- 

 ity of the cooling system is 6 gallons. An expansion tank, 

 connected to the overflow pipe of the radiator, is located on 

 the right side frame member. 



The selective transmission provides three speeds forward 

 and one reverse. The speed is selected by a gear-shift lever 

 mounted in the top of the gear box. A built-in lock en- 

 ables the shift lever to be locked in the neutral position. On 

 the side of the transmission housing is a small Kellogg air- 

 cooled, 1 -cylinder air pump. This pump, for inflating tires, 

 is operated by engaging its driving gear with one of the 

 transmission gears by means of a small lever attached to 

 the pump.
