| 435 Takes the Road Studebaker Champion coupe 1 17/32 in. Camshaft drive is through a cast-iron pinion on the crankshaft meshing with a Celoron gear on the camshaft. Gasoline is supplied from the 15 gal. rear tank to the Carter down-draft 1 1/4 in. carburetor by an AC pump driven by an eccentric on the camshaft. The carburetor is fitted with an AC air cleaner, and the heat supply to the inlet manifold is controlled automatically. Ignition is by an Auto-Lite unit, with 3 3/4 deg. manual advance (to compensate for changes in the anti-knock valve of the fuel); 14 (crankshaft) deg. advance by the speed-sensitive timing governor, and 18 (crankshaft) deg. advance by the inlet-manifold vacuum. The Auto-Lite ignition coil draws from 1/2 to 1 1/2 amps. with the engine idling, and from 4 to 5 amps. in normal operation. Champion spark plugs are supplied, while the ignition switch is of the Mitchell Specialty Company's make. Lubrication is by pressure feed to all main, connecting-rod, and camshaft bearings. Oil is circulated by a gear pump with helical-toothed gears. The pressure-relief valve is set to open at 40 lb. per sq. in. Cylinder walls and piston-pin bearings are lubricated by spray, but there is direct pressure lubrication to the valve tappets, as clearly shown in the transverse section of the engine. Cooling water is circulated by a belt-driven centrifugal pump and its circulation is controlled by a thermostatic valve. The radiator is a McCord cellular type, and the fan of Section of self-sealing, self-lubricating water pump Automotive Industries April 1, 1939 | ||
