Diesel Power

Review—Sulzer (continued from page 37) tion of 117 grams per bhp hour for an RTA84 engine at 85-percent load, ISO-reference conditions. The exhaust energy available for con- ventional waste heat recovery is decreased slightly depending upon the individual rating. The overall result of the Efficiency Booster is additional fuel savings of up to 3 g/bhph.

The very latest generation of

BBC high-efficiency turbochar- gers, type VTR-4A, has ample spare capacity for meeting the design re- quirements of today's RTA en- gines. The Sulzer Efficiency Booster thus uses a concept devised by

Brown Boveri to recover surplus exhaust gas energy and feed it di- rectly to the engine crankshaft through an intermediate trans- mission. The integral power take- off unique to the RTA design is ideal for this concept, allowing the compact Efficiency Booster unit simply to be flange-mounted di- rectly onto the engine.

Delivery of RTA engines with

Efficiency Booster systems de- pends upon the availability of the new VTR-4A turbochargers and the new power turbine modules from Brown Boveri and its licen- sees. Sulzer expects that the

Booster will be available for RTA engines that are due for shop test-

The output range (mcr) of the

RTA series runs from 3,720 bhp at 196 rpm for the 4-cylinder RTA34 to 54,000 bhp at 90 rpm for the 12- cylinder RTA84.

TRANSAMERiCA DELAVAL

Circle 38 on Reader Service Card

Transamerica Delaval's Engine and Compressor Division in Oak- land, Calif., designs and manufac- tures the Enterprise R and RV medium-speed diesel engines, which have proved themselves in hundreds of thousands of operat- ing hours, powering vessels rang- ing from 1,000-foot Great Lakes ore carriers to offshore workboats.

The R4 series comprises 6- and 8-cylinder in-line engines and V- form engines with 12, 16, or 20 cylinders. The bore is 17 inches and the stroke 21 inches (432 x 533 mm), and the output ranges up to 677 bhp per cylinder.

The latest development in the

Enterprise line of marine diesels is the R5. Operating at 514 rpm, the R5 produces 850 bhp per cyl- inder with a bmep of 275. Bore and stroke are the same as the R4.

Through selective redevelopment and design advances in critical en- gine parts, the R5 has achieved, compared with the R4, a 40-per- cent increase in bhp per cylinder, 40 percent more bhp per square foot of installed space, and a 3.5- percent decrease in fuel con- sumption.

The ability to burn heavy fuel oil reliably is paying off for a wide range of Enterprise-powered ves- sels. Three 36,500-dwt bulk car- riers built by Levingston Ship- building for the Falcon Shipping

Group are each powered by twin

R4-V-12 direct-reversing engines, providing a total of 15,600 bhp.

The ability to burn heavy residual fuels makes these unsubsidized vessels competitive with foreign- flag bulk carriers.

Four Enterprise R4-V16 diesels power the two 33,600-dwt tankers built by Bath Iron Works for the

Falcon Group. These ships are chartered to the Military Sealift

Command. Their R4-V16s, each rated at 7,360 bhp, are designed to operate on various fuels including cheaper, heavier grades with vis- cosities up to 3,500 sec Redwood 1.

Transamerica Delaval has com- plemented its Enterprise diesel line by signing a licensee agree- ment with the Dutch engine man- ufacturer, Stork-Werksppor Diesel

B.V. of Amsterdam. This agree- ment gives Transamerica the rights to the exclusive U.S. manufacture of the Enterprise/SWD TM 620 diesel. This engine, which oper- ates at up to 430 rpm, is offered as a 9-cylinder in-line unit with an output of 16,650 bhp, and a V-con- figuration 12-cylinder unit rated at 22,200 bhp.
