I was looking thru my library tonight and open a book I have not read in awhile Aviation Engines by Lieut Victor W. Page copyright 1917 and stumble upon these pages. Take a look at just how advanced Sunbeam engines were in 1917, 500hp and overhead cam with three valves per cylinder, just amazing. I thought some of you might enjoy a look at these engines designed by Louis Coatalen. Engine pictured is eighteen cylinder 475hp OHC six magnetos, two on each bank feeding two spark plugs per cylinder. The quality of the castings are beautiful and way ahead of its time. Almost looks WWII vintage not WWI.

When you look at the basic layout, and think about such things as turbosuperchargers being used in WWI, it's true that very few fundamentals were not already known and used in internal combustion engines a century ago.

Sunbeam (and Wolseley) also made Hispano-Suiza aero engines way back when.

They had the fundamentals and metalurgy. They did not not have good lubrication. That had to wait until WWII.
