Small air-cooled engines
Wisconsin's fame came from its small air-cooled engines, such as AEH, AEN, and VF4. In the 1950s they were able to claim they were the world's largest manufacturer of heavy-duty air-cooled engines. All Wisconsin's products were 4-cycle and they had power outputs from. There were single, inline two, V-two, and V-four cylinder models. The engines were designed for outdoor field service in industries including agriculture, construction, marine, oil-field equipment and railway maintenance. There are a wide range of variations in each engine family, including displacement, vertical and horizontal crankshafts, power ratings, and fuel used. Fuels can be gasoline, heating oil, kerosene, LPG, and CNG.| Model | Type | Power | Displacement | Years | Notes |

Engines for cars and trucks
New automobile companies bought them for their big cars. The Stutz Bearcat car was available with either Wisconsin's four-cylinder Type A or their six-cylinder engine. Both engines were rated at 60 horsepower. Stutz began to build their own engines in 1917. Pierce-Arrow was among other customers for Wisconsin engines. Wisconsin engines also powered the trucks made by The FWD Corporation. Between 1945 and 1965 King Midget Cars used a Wisconsin AENL single cylinder engine in their micro car.| Model | Type | Displacement | Power | Years | Used in |
