Gas Producer Cars
Gas producer cars, Kubelwagens and Beetles around World War II featured a ‘T230 gas generator’ in front of the front axle, where one would expect to find the spare tire. This gasifier was designed to convert fuel such as gasoline or alcohol into combustible gas, allowing vehicles to operate even when scarce resources were available.
The T230 gas generator was developed by German engineers during World War II as an emergency option for vehicles in need of fuel due to a lack of regular supplies. It consisted of a carburettor that atomised the liquid fuel and mixed it with air before passing through a venturi-like device that produced an even mixture for combustion. The output from this device is combustible gas, replacing traditional fuel sources.
The T230 gas generator was relatively simple in design but required frequent maintenance and had certain limitations. For example, the atomiser could not adequately vaporise some fuels, resulting in incomplete combustion and power loss. Additionally, carbon monoxide buildup inside the vehicle presents a common hazard associated with its use.
Despite these drawbacks, the T230 proved helpful during wartime. It allowed mechanically inclined drivers to keep their vehicles running with minimal resources and only essential tools. Over 2 million Kubelwagens and Beetles were equipped with innovative gas devices during World War II.
Components of VW 7230
Some components of the VW T230 woodgas fuel system included:
A large (8″ diameter by 30″) gas filter canister is located just ahead of the windshield (under the hood, in the case of Type 60).
A secondary, rectangular gas filter (about 12″ by 2″ by 48″) is located crossways beneath the car behind the front wheels.
A gas pump or fan is located behind the rear torsion bar tube.
A small final canister filter in the engine bay.
A fuel mixer at the engine intake manifold.
