The design originated in 1914. This design is from about 1920. Gradual improvements were made until it was phased out in the mid 1930's. Wings on the pistons to help air circulation were deleted in 1928 when the compression was raised. Power on this type of engine reached 70 H.P. per cylinder These engines could be ordered with 1 to 9 cylinders. Generator: Fairbanks Morse 28 pole, 100kW, three phase, 440 volt AC. The information above is taken almost word for word from the paper that was put up by the musem describing the engine. This video was shot during the 11am. startup of the engine on Sat. June 26, 2010 at the Antique Gas & Steam Engine Museum in Vista, CA. The other engine toward the end of the video is a straight six Enterprise diesel that was used as a backup power supply at the Palomar Observatory on Mt. Palomar, CA. I did not get the specs for this engine.
