This name is confused in some texts as "Lamplong".

-Lamplough presented a 6-cylinder rotary engine at the Olympia in Paris in 1911. It was two-stroke with blower and supercharger in a cylindrical box at the rear to force the mixture to the cylinders with slight pressure.

“Lamplough rotary engine”

-A clearer illustration is provided here. The exhaust valve was on the head of each cylinder and was controlled.

-The intake was done by the piston uncovering some ports at the end of the lower stroke, thus there was a sweep and cleaning of gases. This way burning was much better and aided by the centrifugal force of the engine rotation.

- It is said that Lamplough also built a barrel type engine.

From Appendix 6: It turns out that it is the name of what would be the Lockheed, once Americanized the last name. See also Lockheed.

-At the Hiller Museum there is the two-cylinder engine that is mentioned above. It is perfectly preserved.

“Lamplough -Lockheed-”

-After the rotary mentioned in the main text, we now present an engine that is known as the 2-stroke “Multiple-Compound”.

-It is a V-cylinder engine but not all of the cylinders carry out a power stroke.

-Having eight cylinders, four act with compressor strokes and the other four with power strokes.

-The first prepare the mixture under pressure to introduce it into the power cylinder by carrying out the convenient sweep.

“Interesting engine aspect”

Author's note: Without a doubt there is an error in the information source about Lamplough USA relating it to Lockheed. See Longhead

-In aviation Lamplough is known for a rare rotary but no less rare is another engine - it does not seem aviation - with a somewhat atypical construction, which we bring here as a curiosity and to look for construction traces with the really aeronautical one.

“Group of front cylinders”

-It seems that the front cylinder prepares the pressure mixture to introduce it into the twin power cylinders.

-The connecting-rod system of the first group is articulated, one part driving a piston and the other a shirt.

"The connecting-rod system of the first group is articulated"

-The main part has two pistons with an articulated connecting rod, similar to the Szidlosky engine and others like that of the Iso motorcycle.

-But Lamplough's Rotary Radial engine for aviation is still more important to us.

-In the main text a barrel engine of this builder is mentioned, because here we have it. It is an engine called “Positive Explosion Turbine”

“Lamplough barrel engine”

From Appendix 10: Another photo of the Compound has recently arrived thanks to a collaborator. With some better defined detail.

“Two-stroke Compound engine”

-In an ad of this brand we find, in addition to the two-stroke engines of the main text, the surprise that Lamplough owns patents on internal combustion aviation turbines.

“Lamplough ad”

-It will be interesting to locate the type of turbines they planned.
