Wall 1906 Horizontal 4-Stroke Vapor Engine by Elmer Wall, IL.
Reported to be Elmer Wall’s first engine from 1906 it is built from aluminum, iron, and bronze castings. In a “vapor” engine the air entering the engine during the intake cycle draws fuel vapors from the surface of the gasoline inside the tank to produce the combustible mixture. It is a 4-cycle horizontal with a throttle, air adjustment, vapor needle valve, and spark advance. A wick oiler is located atop the cylinder for the piston, rings, and valves. Another one is located on the crankcase for the crankshaft and a small oil cup is located on the connecting rod. The cams, gears, lifters, and rockers must be manually lubricated before operation. The engine was sold complete (as shown) with the running box which housed a battery and buzz coil for spark ignition. Without the box it measures 8.5 inches wide, 7.25 inches high, and 14 inches long: it has a bore of 1.5 inch, stroke of 1.5 inch, and weighs 17 pounds.
