1935 Continental Spark Ignition Fuel Oil Engines??

A squib in the Feb 1935 issue of Roads & Streets (a road const mag)announced the availability of Continental carbureted spark ignition oil burning engines, all 6cyl OHV "heavy duty" type in 381, 428 and 501 cids.
Very little tech info was given; it did NOT mention starting on gas and switching to the fuel oil (named as "furnace oil (#1)", or mention a dual fuel carb, but that doesn't mean those weren't used.
1935 was the heyday of the Hesselmann engine, that has an injector pump and injectors, but only gas engine compression, firing diesel fuel by a special hi-power mag and special sparkplugs. Wauk, Allis, Case, and probably others, built these here. They were much more popular in Europe, where fuel taxes were (are) mush higher; this engine, however, used a carb, not injectors.
With the extreme confusion between industry grades of "fuel oil" and the local names, it's hard to tell what was then considered "#1 furnace oil", but I assume it was quite thin.
Anyone here remember these, or hearing about them, assuming they actually were sold?? The squib said "power units and industrial", so apparently no truck version.
Any comments appreciated. Many thxx!! Bud

In the north country #1 fuel was the standard for outside tanks and diesel engines once it gets below 0 F. Its not as light as kerosene but it will flow down to -60 F.

AC built "oil" engines in the 1930s and 1940s for use in industrial equipment.
