“Hendee Indian rotary radial engine”

-The engine was presented at the Boston Show, around 1911. The first defects of the previous models were corrected, the main one being the spark plugs filled with lubrication oil, due to the position of these plugs.

-The mixture circulates inside the engine and enters the cylinders through automatic valves aided greatly by the centrifugation, and the improperly placed spark plugs acting as "cups", instead of preventing the oil from entering by the centrifugation and engine rotation.

-The author notes that the engine is fixed at the rear as most rotaries, but it also has a front collar attached to a support.

-Possibly with a bearing between the support and the engine. This would give the whole more firmness.
