Puch's two-stroke double-piston engines
In 1923, after the first World War and the collapse of the Austro-Hungarian empire, the Italian engineer Giovanni Marcellino designed a two-stroke-engine with uniflow-scavenged split-single-cylinder and double-piston. An important feature is the leading exhaust- and the trailing inlet-piston, resulting in an asymmetric port timing.
The picture shows the older double-piston engine with a fixed fork-rod and a longitudinal bearing in the inlet piston, build from 1923 ("Puch LM") to 1949 ("Puch 125").
The later models, from 1949 ("Puch 125TS") up to 1970 ("Puch 250SG"), had a connecting rod hinged on the back of the other.
