Hubert Schillings, of Germany, designed several miniature engines from 1970 to 1980. Configurations vary from 1-cylinder aircraft engines to 2-, 3-, 4-, 6- and 8-cylinder inline and V-type engines for both aircraft and automobiles. Most of his engines were machined from aluminum bar stock. The crankcase on this two-cylinder is one of only a few that he machined from magnesium.
This 2-cylinder “V” Dual-Over-Head-Cam (DOHC) has cylinders 90 degrees apart and in line with the crankshaft, similar to a V6 or V8 configuration. Each cylinder has two valves (one for intake and one for exhaust) and the camshafts are belt driven 1:2 off of the crankshaft. Two camshafts operate the valves. One camshaft operates the intake valves and the other the exhaust valves, thus “dual overhead cams. Finished in 1975, this engine is 8”-long, 9”-wide, and 6”-high.
