Diesel Power Review —B&W-Allis Chalmers (continued from page 18) of B&W low-speed engines on the U.S. market. The old Burmeister & Wain diesel traditions are carried on in the new company, B&W Die- sel, which after the takeover by M.A.N, is enjoying a well-secured financial base. In order to inten- sify the cooperation, a joint com- pany has been formed — M.A.N.- B&W Diesel GmbH — to coordi- nate all diesel engine marketing and licensing activities. Development of 2-stroke, low- speed engines will be concentrated in Copenhagen as B&W's respon- sibility. These engines will follow the uniflow scavenged design that in recent years has made com- mendable improvements in fuel consumption. B&W recently announced, and already contracted for, an up- Power in BHP Engine type No. of cyl.

Mitsubishi Heavy Industries, Ltd. produces 20 million horsepower annual- ly and does it at an economical price. Mitsubishi has been building diesel engines for over 65 years. Their design- ers know that fuel quality is declining and design their engines accordingly. Install Mitsubishi Diesels in your next vessel.

The new L-GB engine has 15 percent higher output with a 3 gram per horsepower-hour re- duction in fuel consumption. A fuel-optimized version, the L- GBE, has the same rating as the successful L-GFCA engine but with a substantial fuel reduction of 6 grams per bhp-hour. The L-GB and L-GBE, which will be available from 1983 onward, will be equipped with automatic ad- justment of the fuel injection lead to achieve a further reduc- tion in fuel consumption at part load. The new L-GB and L-GBE Series will include a completely new size of B&W crosshead en- gine — 350 mm bore, developing 680 bhp per cylinder at 200 rpm. With outputs down to 2,720 bhp, it will be a direct competitor to many four-stroke, trunk piston engines. P-max % 90 ) 80 • 70 j 60 • ASFOC | * 4 | 2 | / 0 J -2 | 7—H -4 • 50 75 100 pet.

The joint M.A.N.-B&W four- stroke, trunk engine program em- braces the original M.A.N, de- signs and the smaller B&W T/V 23L and S U 28L models, capable of burning heavy fuel. Recently, the largest ocean- going tugboat ever built in the U.S. for Belcher Oil Company, was delivered equipped with a B&W low-speed engine of the type 7L67GFCA. Another recent milestone was the installation of long-stroke, low-speed B&W engines in RO RO vessels for the Swedish ship- owner Brostrom, utilizing the en- gines' ability to accommodate an extremely low engine room height.
