Werkspoor Diesel, now Stork-Wart - sila Diesel. The engine manufactur- er now offers one of the most com- plete medium-speed engine lines on the market. Both the wide product range and the combined market po- sitions of the two companies en- hance the competitiveness of the new venture. Wartsila Diesel's product range includes the well-known Vasa 22, 32 and 46 engine series. The Vasa 22 and the Vasa 32 are widely used in the marine market as main and aux- iliary engines in a variety of vessel types. The Stork-Wartsila Diesel engine line reinforces Wartsila Diesel's product range for both marine and land-based installations. The SW 280 complements the Vasa main en- gine range, and is suitable for vari- ous small and medium-sized vessel applications such as tugs and dredg- ers. The TM 410 and 620 engines have excellent operational records in a wide scope of marine propulsion applications. Both engine types are suitable for diesel power plants, a growth sector for Wartsila Diesel. • Circle 79 on Reader Service Card Volvo Penta of America recently announced that it has increased horsepower ratings for most of its marine diesel models. Leading the way is the 16-liter TAMD162B, producing 612 hp at 2,100 rpm, for pleasure or light-duty application. The 162B is turbo- charged and aftercooled and fea- tures four valves per cylinder all contributing to highly efficient com- bustion and low emission levels. The TAMD162 is also available in a me- dium-duty rating of 490 hp at 1,900 rpm and a heavy duty version rated at 470 hp at 1,800 rpm. Volvo Penta's popular 12-liter TAMD122 is now available in a higher output, lower profile "D" model with 480 hp at 2,050 rpm. Other versions of this engine in- clude the light or medium-duty TAMD122A, developing 450 hp at 2,000 rpm and 400 hp at 1,900 rpm, respectively. The continuous (heavy) duty 122A produces 380 hp at 1,800 rpm. Suited for smaller vessels are the 10-liter model TMD102A and the 12-liter TMD122A. Available in continuous ratings of 238 hp at 1,800 rpm (102A) and 300 hp at 1,800 rpm (122A). These turbo- charged (non-aftercooled) diesels provide reliable, economical propul- sion or auxiliary power in all types of installations. The turbocharged, aftercooled TAMD71 and TAMD61 represent the very latest development in ma- rine diesel technology. The seven- liter model TAMD71B is an in-line six-cylinder power plant that pro- duces 380 hp at 2,600 rpm and is suited for high performance fishing and pleasure boats. Its counterpart, the TAMD71A is available in light, erships. The first engine was demonstrated at the Aioi engine works of Diesel United in Japan. Already there are orders for 14 of the model RTA84C engines with six, eight, nine and 10 cylinders and a total power output of 615,000 bhp. The RTA84C provides up to 3,820 kw per cylinder (5,200 bhp per cy- cle) at 100 rpm. Thus, with up to 12 cylinders, the RTA84C can supply a maximum continous output of 45,840 kw (62,400 bhp). It responds to the trend towards larger, faster containerships that require much more propulsion power. The first RTA84C will be in- stalled on a 3,600-TEU container- ship under construction at the Kure shipyard of Ishikawajima-Harima Heavy Industries Co. Ltd of Japan. The unit will be a nine-cylinder model of 33,100 kw (45,000 bhp) at 100 rpm. Sulzer RTA Series engines have been very successful in the propul- sion of large containerships, partic- ularly with the 840-mm bore RTA84 and RTA84M models. Of the 117 engines of these models ordered so far, 55 have been for containerships. However, in discussions for new- building projects in the past two to three years, there have been increas- ing indications towards the need for higher shaft speeds and higher pow- er outputs. VOLVO PENTA medium and heavy duty versions. Horsepower ratings are 350 hp at 2,500 rpm, 286 hp at 2,500 rpm and 218 hp at 2,000 rpm. The six-liter TAMD61A remains unchanged at 306 hp at 2,800 rpm for light applications and 228 hp at 2,500 rpm for medium duty. WARTSILA DIESEL Circle 67 on Reader Service Card Wartsila Diesel Inc., the U.S. sub- sidiary of Wartsila Diesel, has ac- quired the Power Systems division of the Morrison-Knudsen Corpora- tion, Rocky Mount, N.C. The com- pany will be renamed MKW Power Systems Inc. Both Wartsila Diesel Inc. and MKW Power Systems sup- ply diesel engine packages to the power plant and marine propulsion systems in North American market. Operations include service and spare parts sales. The acquisition will expand the U.S. market for Wartsila Diesel heavy oil and gas engines. MKW Power System Inc. will also use Wartsila Diesel engines in its power system packaging. According to Clas-Eirik Strand, president of Wartsila Die- sel Inc., the company acquired is one of the leading diesel engine sys- tem packagers in the U.S. "The company also designs and manufactures first-class control sys- tems," said Mr. Strand. "Thanks to the acquisition, we will be able to offer our customers more competi- tive products with an extremely short turnaround time." Pentti-Juhani Hintikka, pres- ident of the Wartsila Diesel Group, explained that in the future, the company will concentrate more on comprehensive packaging for mod- ular and standard power plant types and on ready solutions in general. "We will be investing more and more in ecofriendly gas and multi- fuel engines," said Mr. Hintikka. Wartsila Diesel is one of the world's leading manufacturers of diesel engines, with production plants located around the world. The company recently acquired a 60 percent share in Dutch Stork- Circle 222 on Reader Service Card L'Orange GmbH the heart of the driving force Since the invention of the die- sel engine, the course of its development has been shaped by L'Orange injection systems. The diesel's present significance as a highly load- ed engine is still tightly con- nected with the name L'Orange. Major engine ma- nufacturers have placed their trust in L'Orange injection technology as the key to the design and operation of very economical large diesels. In close co-operation with the international diesel-engine industry, L'Orange is active in the development of new in- jection systems and the im- provement of those already in operation. The aim is further optimization of the diesel en- gine - optimization defined as increased performance, reduced fuel consumption and longer service life. This is a development wich is assur- ed by the engineering excel- lence of L'Orange in the field of injection technology. LDrangB Injection Systems P.O.
