ply the main engines for the type 471 submarine for Royal Australian Navy. Hedemora Diesel is able to offer the market a comprehensive engine selection with output per unit from 20 kW up to 15,000 kW by utilizing a variety of fuel and com- bustion technology applicable to heavy oil, marine diesel, gas oil and the newest development of natural and biogas fuel systems. Hedemora Diesel has its origins in an engineering company estab- lished in the 19th century in Bergslagen, traditional heartland of the Swedish mining and metal in- dustries. The production of engines was started in 1906, and the first diesel engines were built in 1946. For more information on Hedemora Diesel AB, Circle 67 on Reader Service Card KHD Canada At the Hanover Fair, the Duetz MWM division of the KHD group presented the new 234B diesel en- gine series, further developed from the well-established 234 series with new technology which will be intro- duced within the power class up to 1,360 kW. Essential features of the new Deutz MWM product include: long-stroke technology, four-valve technology, Hallo swirl and a new cooling system. Together with an enlarged displacement from some 1.8 to 2.2 1 per cylinder (22 percent), this technology establishes the pre- condition for an uprating maximum of 33 percent. The major objectives of the advancement were higher out- put with identical installation space requirement and lower emission lev- els with maximum operating economy. The Deutz MWM TEM system (Total Electronic Manage- ment), presented in 1992, will now, after the introduction of the 234B series, also be used within this power range for spark ignition. For more on the Deutz MWM 234B, Circle 111 on Reader Service Card Krupp MaK Krupp MaK markets medium- speed diesel engines in the power range from 1,073- to 14,'751-hp. The German engine builder offers four different series, both as in-line and "V" configurations, with speeds be- tween 425 and 1,000 rpm. The goal of the current Krupp MaK C engine program is to incor- porate the latest developments to improve economy, operational safety and exhaust emissions. Krupp MaK recently added the M 20 engine series to its medium-speed diesel line. The M 20 is a long-stroke engine with 200 mm diameter and a stroke of 300 mm in the output range from 900 to 2,700 kW (1,207- to 3,621-hp) at 1,000 rpm. The M 20 is available in six-, eight- and nine-cylinders in-line and 12- and 16-cylinders in a "V" con- figuration with speeds between 900 to 1,000 rpm. The M 20 is geared toward coastal July, 1993 & ULSTEIN and inland vessels both as main propulsion and auxiliary power ap- plications. Krupp MaK reports the fuel consumption to be about 183 g/ kWh. The new model is suitable for both main propulsion and auxiliary power and can be operated on all established grades of heavy fuel oil.
