 The Fairbanks Morse Opposed Piston (OP) engine has been designed and developed for a wide array of electrical power generation

and heavy industrial applications. You will find OP engines propelling ships, driving locomotives, powering natural gas compressors,

running chillers and pump drives, and producing electricity in a variety of marine and stationary applications. OP engines have even

provided standby power for the country's most critical applications, including take-home power for nuclear submarines, emergency

reactor cooling in nuclear power facilities, and emergency power for vital life support and telecommunications networks.

Regardless of the specific application, economics and environmental concerns determine the best technology - high efficiency and low

emissions result in economical power generation and ease of site permitting. When equipped with Enviro-Design®, dual-fuel

technology, the OP engine is ideally suited for low-cost electric power production and is one of the most efficient low-emission natural

gas engines in the world. Available today: one pre-owned, OEM-inspected 12-cylinder OP Enviro-Design® Dual Fuel engine

generator set. Click for details

Engine ConstructionCylinder Block - A "shock qualified," precision-welded steel block designed for structural rigidity and a design life exceeding 40 years.

Dry block construction eliminates leakage and extends frame life. Large access openings at five levels in the engine improve

maintenance.

 Turbocharging - High-efficiency turbocharging and pulse manifolding improves cylinder scavenging, thereby improving efficiency and

lowering emissions. Optional Turbo-Blower Series design provides fast-starting and high-load acceptance capability, ideal for

combination emergency stand-by and peak shaving applications.

Cylinder Liners - Two pistons inside the cylinder liner form the combustion space, eliminating cylinder heads, valves, and associated

hardware. Compared to other engine designs, Opposed Piston engines have less than half the moving parts.

Pistons, Bearings, and Connecting Rods - Upper and lower piston assemblies may be removed from the lower crankcase, simplifying

maintenance procedures. Connecting rods are forged from high-tensile-strength alloy steel. Due to the Opposed Piston's two-stroke

cycle design and conservative operating speed (900 and 1000 rpm), aluminum alloy main and rod bearing life is extended.
