W18 engine

From Free net encyclopedia

A W18 engine is an eighteen cylinder piston engine in a W configuration. Recent W18 engines powered the Bugatti EB 118, Bugatti EB 218 and Bugatti EB 18/3 Veyron concept cars in the late 1990s. This engine featured three banks of six cylinders set 60 degrees apart.

An earlier example is the Isotta-Fraschini "Asso 750" used to power the Italian Savoia-Marchetti S-55 seaplanes flown by Italo Balbo into Chicago in 1933. This engine used the same layout as the above-mentioned Bugatti - basically a vertical six with two adjacent banks set at 60 degrees each to make a W-18.
