1926 Packard 326 Six
The six-cylinder engine featured a seven main bearing crankshaft, and a bore and stroke of 3 ½ " x 5". Brake horsepower was listed at 61. The engine also incorporated two unique items: an oil rectifier, and a 'Gasolizer'. The former was used as an oil purifier, burning off condensation and fuel that had contaminated the oil. It was a complicated system that was dropped in later years in favor of a more conventional filtration system. The Gasolizer, used only on this Series, was an experimental 7th combustion chamber mounted on the carburetor, complete with a spark plug, fuel supply, and sight glass for visual adjustments. Its function was to vaporize the fuel prior to entering the intake manifold, thus improving fuel economy and performance.
