B&W Offers Technical Paper On Advantages Of New Low-Speed Diesels

A forty-five page technical paper entitled "The Low-Speed Diesel and The Future Energy Scenario" has been published by B&W Diesel, Inc., New York, a subsidiary of B&W Diesel A/S, Copenhagen, Denmark.

Well illustrated with drawings, charts, tables and photographs related to the text, the paper describes technical considerations of the low-speed diesel as the most efficient converter of thermal energy into mechanical power.

The paper traces the development and design parameters of the company's low-speed diesels from the K-GF engines first produced in 1973 to the newly introduced L-GB engines. The new engines, the paper states, optimize the combination of longer stroke, h i g h e r o u t p u t , higher maximum cylinder pressure, and the latest turbochargers producing high-thermal efficiency.

The new engines range from the L-35 GB/E to the largest, the L-90 GB/E. The L-35 has a 350-mm cylinder bore and a stroke of 1,050 mm which apply for the first time a stroke-bore ratio of 3:1. The cylinder output ranges from 690 bhp at 200 rpm to 405 bhp at 163 rpm. Specific fuel oil consumption down to 129 g/bhph is guaranteed.

The largest of the new engines is the L-90 GB/E which is based on the existing and well-proven GFCA design. The cylinder output ranges from 4,570 at 97 rpm to 2,740 bhp at 79 rpm. Specific fuel oil consumption down to 126 g/bhph is guaranteed. Most of the GB/GBE engines will be available starting in 1983. For a free copy of the paper, Write 22 on Reader Service Card
