Summary
This somewhat unique artifact is an air-cooled, two-stroke cycle rotary aircraft engine designed and built by Paul Daniel of the Daniel Engine Company of Bound Brook, New Jersey during 1918.
Most rotary engines utilize the four-stroke design concept; and generally have an odd number of cylinders to gain a relatively smooth, vibration free operation through an even piston firing order. However, two stroke engines, with twice the number of power strokes as a four-stroke engine, can effectively use an even number of cylinders.
According to the donor, the last and possibly principal use of this engine was as a “technical step for classroom study” in the Department of Mechanical Engineering at New York University.
