Diesel Power Review (continued) other principal features of the new series include high propeller effi- ciency, high reliability, low-quality fuel compatability, easy mainte- nance, and compact design. The UE engine is the only low-speed diesel developed entirely in Japan.

The four models in the LA Series are each available in versions from four to eight cylinders. The largest engine in the series, the UEC60LA, has a bore of 600 mm and a stroke of 1,900 mm, and has a maximum con- tinuous output of 2,100 bhp per cylinder at 110 rpm. The UEC52LA has a 520-mm bore and 1,600-mm stroke, with an output of 1,600 bhp per cylinder at 133 rpm. The

UEC45LA model has a bore of 450 mm and stroke of 1,350 mm; output is 1,200 bhp per cylinder at 158 rpm.

The fuel consumption of these three models has been cut 5 g/bhph com- pared with the former L series.

The UEC37LA is the smallest en- gine in the series, with a bore of 370 mm and a stroke of 880 mm. Its out- put is 700 bhp per cylinder at 210 rpm. Fuel consumption for this model has been cut to 129 g/bhph at maximum rating and only 126 g/ bhph at economy rating.

For all of the LA Series engines

Mitsubishi quotes what it calls "ca- pable minimum fuel consumption rates." These range from the 116.5 g/bhph for the 60LA model to 123.5 g/bhph for the 37LA.

MTU

Circle 32 on Reader Service Card

MTU of North America, Inc. is the U.S. subsidiary of MTU-Motor- en and Turbinen-Union of Fried- richshafen, West Germany. The

German parent company is jointly owned by Daimler-Benz A& and

M.A.N. AG.

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 features common to the series are: V-config- uration, water cooling, exhaust gas turbocharging, and charge air cool- ing. All engines are the result of the collective experience gained by

Maybach, Mercedes-Benz, and

M.A.N, in the development of cost- effective, high-performance diesels.

The model 20V 1163 TB 93 en- gine, introduced in 1983, is evidence of MTU's continued success in its engine development program, which focuses on increasing engine power and power concentration to open new powering possibilities, reducing fuel consumption throughout the entire speed range, extending oper- ating range through higher mean effective pressures, and improving partial-load performance character- istics. MTU employs cylinder cut- outs, cylinder charge transfer, and sequential turbocharging in some of its engines.

MTU's two-stage turbocharging is also employed in addition to the other systems mentioned. This al- lows overall engine dimensions to be kept almost constant, and results in a power-to-volume ratio of 11.7 bhp per cubic foot, and a weight-to-pow- er 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 bph 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.

PENSKE

Circle 33 on Reader Service Card

Since 1976, Penske GM Power,

Inc. of Lodi, N.J., has expanded its facilities to include four sales and five service locations, including its newest on-water service operation in Monmouth Beach, N.J. Serving the requirements of both pleasure craft and commercial vessels,

Penske's facilities are located throughout the metropolitan New

York/New Jersey/Connecticut area.

More on-water locations are planned for opening this year and in 1987. In addition to Detroit Diesel

Allison, Penske's product line in- cludes Alco, John Deere, and Volvo-

Penta.

Penske is engaged in various ap- plications of diesel power, with divi- sions specializing in high-perfor- mance pleasure craft and commer- cial marine power; mobile, prime, and standby electrical generators; and transportation, firefighting, and industrial applications. The compa- ny is able to service all aspects of diesel engine applications. Penske- engineered marine propulsion is currently in use in military, com- mercial, and high-performance pleasure-boat applications through- out the world.

The next 10 years promise in- creased visibility for the Penske- engineered product, with new em- phasis on the "Penske Advantage" concept. The "advantage" is race- proven engineering and technology, state-of-the-art production and manufacture, and the "Hot-line" service and parts response that

Penske customers have come to ap- preciate.

The Penske development of a complete GM engine room allows one service technician to service both Penske-engineered propulsion engines and Penske-built on-board electrical generating units. Penske offers diesel engines rated from 56 to 4,000 bhp and gensets 35-2,800 kw.

PERKINS

Circle 34 on Reader Service Card

Perkins Engines, Inc. of Wayne,

Mich., is part of the worldwide Per- kins Engines Group of Peterbor- ough, U.K., which this year has added a powerful yet exceptionally compact diesel to its line of marine engines. A leading supplier of die- sels in North America, Perkins of- fers marine engines ranging from 51 to 800 bhp, in four, six, eight, and 12-cylinder versions. These engines have a wide variety of applications, including main and auxiliary pro- pulsion as well as generator sets.

The latest addition to the Perkins marine line, which was developed in conjunction with the British Royal

Navy, is the 8-cylinder, V-form CV8 536(M) diesel that provides 536 bhp at 2,100 rpm. With low weight and low profile, this engine was designed for many commercial craft applica- tions. The compact size of the CV8 allows for smaller engine rooms, thus offering increased payload.

The CV8's light weight insures a good power-to-weight ratio, and its outstanding fuel consumption is a plus factor in commercial and fish- ing applications. Options for this engine include a power takeoff unit, keel cooling, and change-over fil- ters.

The Perkins marine line is headed by the 12-cylinder, 800-bhp CV12 diesel. This heavy-duty, Rolls-

Royce-designed engine is a 60-de- gree V-form water-cooled diesel.

The new CV8 is next on the power chart, followed by the turbocharged, eight-cylinder TV8.540 diesel with a rating of 350 bhp at 2,800 rpm. This engine weighs less than 1,700 pounds, offering an outstanding power-to-weight ratio.

Foremost in the Perkins line is the

Range 4 family of four high-power, six-cylinder engines. The turbo- charged, six-cylinder T6.3544(M) is the leading member of this family, offering 240 bhp at 2,600 rpm. Two other versions of this engine provide 165 bhp and 135 bhp at 2,800 rpm.

Perkins also offers four-cylinder diesels led by the popular 4.236(M) that provides 85 bhp at 2,500 rpm. The 4.154 (M) has an output of 62 bhp at 3,000 rpm, while the 4.108(M) provides 51 bhp at 4,000 rpm.

STORK-WERKSPOOR

Circle 35 on Reader Service Card

Stork-Werkspoor Diesel BV (SWDiesel) headquartered in Am- sterdam, is Holland's leading diesel engine manufacturer. Its production program covers an output range from 400 to 21,725 bhp, and consists of five models of four-stroke, me- dium-speed, heavy-duty engines, all capable of operating on heavy fuel.

The company's latest engine type, the SW280, is offered in an in-line configuration with six, eight, or nine cylinders, and in a 12-cylinder V- form version, with outputs ranging from 1,965 to 4,735 bhp.

Special attention in Stork's re- search and development program was given to the reduction in fuel consumption, resulting in lower fig- ures for the SW280, F/SW240, and

DR210 engines. R&D on the well- known TM410 and TM620 engine types, of which more than 650 have been delivered, has also been suc- cessful in meeting market demands for reduced fuel consumption; a re- duction in fuel consumption of up to eight percent can be achieved.
