The Embee 75 side-port diesel is the most widely-recognized product of the very prolific model engine manufacturer Peter A. Moore. The engine made its initial appearance in early 1968, being produced at that time by Moore & Bailey of Groby in Leistershire, England - hence the engine's name. Moore left the partnership in 1969 to continue model engine manufacture on his own, still using the Embee trade-name. He produced a surprising variety of model diesels, including an FRV version of the Embee 75, a 2.5 cc twin ball-race diesel, a series of geared twins based on Embee 75 powerplants and a few "mock rotary" diesels intended for scale model use. 

The Embee 75 side-port model was constructed from bar-stock without the use of castings. Its functional design followed that of the earlier Mills .75 very closely. The well-made and nicely finished engine became Moore's best-known product, starting very easily and running well, albeit at a relatively modest level of performance. Despite its name, the Embee's actual displacement was only 0.6 cc.

Beginning in 1979, Moore began making a 0.6 cc derivative of the Embee 75 called the P.M.C. Imp, seemingly using many left-over Embee components. This engine was noticeably less well-made than its Embee predecessor, although most examples ran well enough. 

A detailed account of the Embee and P.M.C. ventures will appear in due course on this website.
