The Aeromotor had the cam geared 4 to 1 instead of 2 to 1. The exhaust lobe was large enough to keep it open for the 5 strokes. These were air cooled engines both internally and externally, didn't use a cooling fan. They were built to put on windmills and pump water when there was no wind. The idea was to start it and let it run unattended until it ran out of gas.
