First Rotary Diesel

First rotary diesel ENGINES Engines 10-4-32 You've never seen anything like this recently patented rotary diesel engine. According to inventor Nolan F. Haynes, Millwood, W. Va., it would be ideal for farm tractrs and other self-propelled equipment. "It has a longer power stroke so it develops more torque than conventional engines," says Haynes. "It's also much more efficient because, among other things, the engine is totally aspirated. It's the first true rotary engine." The engine consists of 5 rotating, equally-spaced cylinders mounted on a central hub above four equally spaced pistons mounted on the driveshaft which spin in the opposite direction. The round ball-shaped pistons enter the cylinders like the mesh of two gears and, as they're blown out by the explosion of fuel, drive the crankshaft. Haynes points out that each cylinder is totally aspirated when the piston leaves it so that unburned fuel is not left in the cylinders, which increases efficiency and lengthens engine life. The new rotary is not yet on the market. Haynes is working with manufacturers interested in the design. For more information, contact: FARM SHOW Followup, Nolan F.
