GM Increases Diesel Power Ratings And Offers New Applications Manual

General Motors is offering a free applications manual which provides full information on new power ratings for both GM diesel-electric power units and marine propulsion engines.

GM has raised the rating of several of its diesel-electric power units and increased the horsepower and fuel efficiency of its line of diesel engines for drilling power and marine propulsion. GM said it has also made available an "F" series crankcase of increased strength to coincide with the higher horsepower ratings.

T.J. Lehman, manager of marine and industrial sales for General Motors Electro-Motive Division (EMD), said the power unit ratings for the 16-cylinder "F" series engines has been raised from 2,400 kw to 2,685 kw, and the 20- cylinder engine ratings have been raised from 2,859 kw to 3,150 kw.

Both models are rated at 900 rpm, 60 Hz. Ratings for 50 Hz, 750 rpm continuous output are 2,040 kw for the 16-cylinder engine and 2,580 kw for the 20-cylinder engine.

The GM 16-cylinder marine engine with heavy-duty crankcase is now rated at 3,400 hp at 900 rpm, up from 3,070 hp. The 20-cylinder marine propulsion engine is now rated at 4,000 hp at 900 rpm. For more fuel-efficient operation and improved blended fuel capability, these engines can be run at 800 rpm, with 3,070 hp and 3,600 hp respectively.

Technical developments including a new, more efficient turbocharger have led to an increase in fuel efficiency of up to 3 percent.
