Looks like we should have read a little closer!
“. But language in this Honda patent, as well as the design drawings, suggest that this might not be conceived as a motorcycle engine at all – at least, not in its current form. In the first background paragraph of the application, Honda states that “the two-stroke engine is often preferred over the four-stroke engine in the field of general purpose engines because of the simplicity in the structure.”
Furthermore, that diagram would seem to show a long-stroke engine with a pushrod valve system and a thick mounting flange at the bottom. In addition, the patent wording states that “the liquid fuel may consist of diesel oil or any other fuel that is provided with a lubricating property.” All of which points toward an industrial generator-type machine rather than a high-performance motorcycle engine.”
Two stroke with a pushrod and a valve…… What next air cooled…. :dry: :p
