V18 engine

ALCO 18-251 engine being used as a backup electrical generator at a wastewater plant in Montreal.

A V18 engine is an eighteen-cylinder piston engine where two banks of nine cylinders are arranged in a V configuration around a common crankshaft.

V16 engines are a rare configuration, with large V18 diesel engines have seen limited use in haul trucks, electricity generation, rail transport, and marine propulsion. There are no known automobiles that have used V18 engines.

Examples

Name Displacement Power output Fuel Notes
ALCO 18-251[1] 12,024 cu in (197.04 l) 4,500 hp (3.36 MW) Diesel Originally designed and manufactured by
American Locomotive Company; now manufactured by
Fairbanks Morse Engine.[1]
Cummins QSK78[2] 4,735 cu in (77.59 l) 3,500 hp (2.61 MW) Diesel Derived from the V16 QSK60.[2]
Marketed by Komatsu as the SSDA18V170.[3]
Wärtsilä 18V50DF[4] 125,000 cu in (2,050 l) 23,530 hp (17.55 MW) Diesel or
natural gas
Available for both marine propulsion and power generation, and used in e.g. Humboldt Bay power station.[5]

The BelAZ 75600 and Liebherr T 282B haul trucks are powered by the Cummins QSK78 engine, while the Komatsu 960E-1 haul truck is powered by the Komatsu SSDA18V170 engine.

In 1972, the Candian locomotive manufacturer MLW-Worthington produced the MLW M640 prototype diesel-electric locomotive powered by the ALCO 18-251 engine, however the locomotive did not reach production.
