VOLVO PENTA Circle 39 on Reader Service Card Volvo Penta of America, Rock- leigh, N.J., has introduced new configurations of its six-cylinder diesel engines. The new turbo- charged/aftercooled version of the 5.48-liter six-cylinder engine is designated TAMD60C. Horse- power has been raised to 250 bhp at 2,500 rpm for the light-duty version, and 210 bhp at 2,500 for the medium-duty model. New this year is a continuous output rating of 177 bhp at 2,200 rpm. The new Robert Bosch fuel in- jection pump is equipped with an aneroid smoke eliminator, and provides a specific fuel consump- tion of 156 grams per bhp hour at the 2,000-rpm continuous rating. The latest configuration of Volvo's 6.73-liter, six-cylinder turbo/aftercooled engine is the TAMD70E, rated 300 bhp at 2,500 rpm. Also available is an interme- diate rating of 270 bhp at 2,500 rpm, or 211 continuous bhp at 2,000 rpm. Both the TAMD60 and 70 are available with heat exchangers or in keel-cooled modes. Higher horsepower with lower fuel consumption is the result of component redesign in the 9.6-li- ter TMD100C engine. A new tur- bocharger, in conjunction with a new injection pump and injectors, pistons, and liners, and a modified cylinder head results in 272 bhp at 2,000 rpm in the light-duty rat- ing. The medium- and continuous- duty ratings are 258 bhp and 238 bhp, respectively, at 1,800 rpm. Specific fuel consumption has been improved to 153 grams per bhp hour. Volvo's largest engine, the tur- bocharged and aftercooled 11.9-li- ter TAMD121C, has had a series of modifications, that are designed to enhance its already substantial reputation for economy and lon- gevity. The cylinder block has been reinforced in the liner ledge area to withstand higher outputs, while the crankshaft has been nitrided to resist fatigue. New cylinder heads with improved water flow support new injectors with im- proved spray patterns and higher pressures. New pistons, liners, connecting rods, and turbocharger all contrib- ute to the 121C's light-duty rating of 408 bhp at 2,000 rpm. Medium- and continuous-duty ratings are 387 bhp at 1,900 rpm and 367 bhp at 1,800 rpm. The engine uses 159 grams of fuel per bhp hour at the continuous rating. A wide variety of transmissions and power takeoffs make both the TMD100C and the TAMD121C ideal power sources for fishing ves- sles or other boats where numer- ous PTOs are required. WARTSILA Circle 40 on Reader Service Card Wartsila Diesel, one of the world's leading manufacturers of medium-speed diesel engines, is part of the Finnish Wartsila Group, with more than 17,000 employees and 35 production plants in five different countries. Wartsila Diesel is made up of the main factory in Vasa, Finland; the Trollhattan factory in Sweden; and the newest factory, Wartsila Power Singapore in Singapore. The company specializes in purpose-de- signed, heavy-fuel diesel engines. The primary objective in product development is to create diesel en- gines with good economy and safe operation, even for the most de- manding applications. As a result of these efforts, Wartsila today is a producer of two high-standard, medium-speed diesels designed and developed from the very beginning for the poorest quality fuels. The heavy-fuel engine types are the Vasa 32 and Vasa 22HF, cov- ering the output range of 800 to 9,060 bhp in the speed range from 720 to 1,200 rpm. The Vasa 22HF, with a bore of 220 mm and stroke of 240 mm, is manufactured as in- line versions with four, six, or eight cylinders and V-form with 12 or 16 cylinders, covering the output range of 800 to 3,210 bhp at 1,000 rpm. The Vasa 32 has a bore of 320 mm and stroke of 350 mm, and covers the range of 2,010 to 9,060 bhp at 720 rpm. The in- line version is built with four, six, eight, or nine cylinders, and the (continued on page 40) Main propulsion for merchant ships, container- carriers, passenger-boats, supply vessels, tug boats. —-,-..,-,-.- Ratings up to 10.000 hp per engine.
