Abstract
Onan's new 40 in3, heavy-duty, air-cooled gasoline engine offers advantages of 2-cyl configuration in a size range formerly dominated by single-cylinder engines. The twin-cylinder-opposed design results in a compact, quiet, extremely smooth-running engine, easily adaptable to garden tractor installations.
The engine features an aluminum die-cast cylinder block. Aluminum die castings are used extensively throughout the design. All components are well tooled for low-cost, high-volume production.
A variety of options are available, allowing tailoring the engine to meet the garden tractor manufacturers' specific requirements.
