Number of points need to be amplified. Some can be debated.
@Rahul Bhagat: Popular early aircraft engines were rotary (as opposed to radial).

Hello Sutripta,

Perhaps it would help to clarify it a bit if you added that the early engines had rotating c/cases & pistons around the stationary crankshaft, rather than the standard definition of a set of reciprocating, radial pistons cranking a rotating crankshaft!

2. Flat/Boxer engine

We now move into the realm of performance engines! Although the number of manufacturers that use the boxer engine have dwindled, with Porsche and Subaru continuing to persist with the boxer engine in their current offerings, the automotive/racing world has fond memories of this engine layout.

This engine configuration was made famous by the original VW Beetle, which used an air-cooled, rear-mounted boxer engine. .......

Hello theMag, a great thread starter, this! And you're right - it would impress the hell out of my circle seeing my tech expertise!
At a slight tangent, I will add that VW had a large stock of their air cooled, flat-4 blocks lying idle after they ceased production of this unit. They apparently sold a consignment to Hatlapa, the air compressor manufacturers. Hatlapa subsequently converted the blocks (minus the reciprocating ohv gear & associated bits and pieces) to air cooled air compressors. These still had the VW logo embossed on the crankcase when I worked on them (I was 2nd Engr at the time) on the "Marine Ranger", a Panamax bulk carrier I was on back in 1990!
