Standardization also allows Alco to take advantage of new production techniques to establish more precise tolerances, which in turn make new, more efficient components interchangeable with previous parts used in older engines. The generator, ac or dc, is often of cantilever design mounted directly on the engine with no flexible coupling.Īs there is no separate generator support, the possibility of misalignment or distortion is minimized, an important factor in marine units.īecause the basic design of the Power Boss remains much the same, Alco has always been able to improve the engine by standardizing and upgrading components, utilizing new materials and technologies. Generators and turbochargers match the capabilities and characteristics of the engine. The Power Boss can be shipped completely packaged with its driven equipment and accessories in a skid-mounted arrangement that can merely be set down in a level area for operation. The four-point mounting also reduces the cost of foundations.
The rear mounts are firmly anchored while the two front mounts can float longitudinally on their hardened steel plates, allowing for expansion. When the engine is used in a generator set, a less expensive generator is required.įour-point mounting, with feet located at the nodes of vibration, is common to all Alco engines. In marine applications, reduction of engine space and weight permit greater fuel storage and therefore better cruising range. These diesels offer particular advantages in marine and generator applications. The 1,200- rpm units are built as an in-line 6, V-12, and V-16 engines. A 12-cylinder, 1,200-rpm unit is said to provide 16-cylinder performance in specific applications. The 1,200-rpm Power Boss is part of Alco's continuing development program of putting more power into less space. With normal maintenance, states Alco, the Power Boss can consistently operate 25,000 hours or more between major overhauls. All have the same bore and stroke, and use the same operating principles.
This fourcycle engine is offered in a power range from an 800-bhp, 6-cylinder in-line to a 4,500-bhp V-18. The Power Boss™ is what this Auburn, N.Y., engine manufacturer calls its diesel. We asked the major diesel manufacturers to tell us about their latest developments this review is based on their replies. All have a common goal: to improve fuel efficiency even while burning lower quality residuals, and to reduce maintenance costs. Some companies have produced totally new designs others have made design improvements to their proven lines. Latest Developments In Fuel-Efficient Engines For The World's Merchant Fleets While fuel costs continue on their upward spiral, and fuel quality continues to decline, the manufacturers of marine diesels have been busy designing new engine types and redesigning older model lines.
