Diesel Power Review (continued from page 33) MTU Circle 30 on Reader Service Card MTU of North America, Inc., Greenwich, Conn., is the U.S.-based subsidiary of MTU-Friedrich- shafen of West Germany. The Ger- man parent company is jointly owned by Daimler-Benz AG and M.A.N. AG. This year MTU-Fried- richshafen celebrates its 75th anniversary of high-performance diesel engine development and manufacturing. Further adding to MTU's world- wide service network, MTU of North America has appointed two product support dealers for engine repairs and overhaul and person- nel training. One of these dealers is The Boat Yard in Seattle, the other is Marine Diesel Service of Coral Gables, Fla. The MTU diesel line covers a power output range of 440 to 10,000 bhp at rated speed between 1,000 and 2,400 rpm. Basic design fea- tures common to the series are: V- configuration, water cooling, ex- haust gas turbocharging, and charge air cooling.

The model 20V 1163 TB 93 en- gine, introduced in 1983, is evi- dence of MTU's continued success in its engine development pro- gram, which focuses on increasing engine power and power concen- tration to open new powering pos- sibilities, reducing fuel consump- tion throughout the entire speed range, extending operating range through higher mean effective pressures, and improving partial- load performance characteristics. MTU employes cylinder cutouts, cylinder charge transfer, and se- quential turbocharging in some of its engines. Power in the 1163 series has been increased from 349 to 496 bhp per cylinder, corresponding to an increase in mep from 305 to 426 psi. MTU's two-stage turbo- charging is also employed in addi- tion to the other systems men- tioned. This allows overall engine dimensions to be kept almost con- stant, and results in a power-to- volume ratio of 11.7 bhp per cu- bic foot, and a weight-to-power ratio of 4.4 pounds per bhp with the 20V 1163 producing 9,920 bhp. Output of the 396 series engines has also been increased. With a maximum rating of 2,570 bhp and a weight of 10,475 pounds, the 16V 396 penetrates a power range that could previously be served only by larger and heavier engines. MTU's marine diesels are de- signed for a wide range of com- mercial and naval applications. These include continuous duty with a power range of 590 to 4,930 bhp, and medium duty with a power range of 640 to 5,425 bhp. Light-duty engines have a power range of up to 10,000 bhp. Some of the advantages of MTU's compact engines include light weight, low volume, and decreased noise lev- els. In addition, they are prepack- aged with accessories for fast, in- expensive installation of the complete power plant. Electronic monitoring and con- trol systems for diesel engines, gas turbines, marine transmissions, and combined propulsion systems complement the MTU product line. MTU electronics include monitor and control systems for unat- tended propulsion plants. Engine room control stands, bridge control posts, and control consoles are also available, as well as simulation systems for personnel training.
