V18 engine
A V18 engine is a V engine with 18 cylinders. A rare configuration not used in automobiles, large V18 diesel engines have seen limited use in mining, electricity generation, rail transport, and marine propulsion.
An ALCO 18-251 V18 engine, used as a backup generator at a wastewater plant in Montreal.
