Gas engine Langen & Wolf

This engine was manufactured by the Italian Society Langen & Wolf in Milan (Subsidiary of Langen & Wolf Gasmo-torenfabrik Vienna) sometime around the end of the 19th century and the begin-ning of the 20th. This a very rare model that well represents some of the archetypal arrangements of the early internal combustion engines. In particular, this engine features an archetypal valvetrain system with a sliding intake valve, strictly derived from that widely used in steam engines in the same period. This engine is also endowed with a very old ignition device which features a pilot flame and a "spool valve", similar to that of a steam engine.
