Perkins North America of Wayne,

Mich., recently introduced an ex- ceptionally compact, Rolls-Royce- designed engine as part of a major entry into the commercial marine diesel market. The new 8HD400T design is an 8-cylinder, V-form en- gine that develops 400 bhp at 1,800 rpm. It is a member of the Rolls-

Royce line of diesels that Perkins has introduced in the U.S. and Can- ada.

Perkins has also introduced other members of its HD family of 4-, 6-, 8-, and 12-cylinder commercial en- gines that provide economical and efficient performance for the com- mercial and fishing vessel markets.

The Rolls-Royce line comprises eight engines with outputs ranging from 210 to 800 bhp in both natural- ly aspirated and turbocharged ver- sions. Only two models are currently available in North America—the 8HD and a 12-cylinder line intro- duced last year.

The first U.S. installation of the

Perkins/Rolls-Royce 12-cylinder marine diesels is in the twin-screw catamaran Bottom Time II deliv- ered recently by Atlantic and Gulf

Boat Builders of Fort Lauderdale,

Fla., to Bottom Time Adventures.

Each of the twin CV12 engines pro- vides 800 bhp at 2,100 rpm.

With the addition of the Rolls-

Royce models, Perkins offers 10 ma- rine diesel engines ranging from 51 to 800 bhp, suitable for main pro- pulsion as well as auxiliary power in a wide variety of vessels, including workboats, patrol and customs ves- sels, ferries, trawlers and other fish- ing vessels, rescue craft, and off- shore supply boats.

These diesels are also suitable for generator sets to provide electrical power for air conditioning, refriger- ation, lighting, and other on-board applications. They are also used in shoreside cargo-handling vehicles.

The 8HD engine was developed in cooperation with the British Royal

Navy. This diesel represents the first coordination of the design tal- ents of engineers at both the Per- kins plant in Peterborough, Eng- land, and the former Rolls-Royce factory in Shrewsbury.

The lightweight 8HD, with good power-to-weight ratio, is a low-pro- file engine designed for many appli- cations in commercial craft. Its com- pact size allows for smaller engine rooms, providing more space for car- go or accommodations, as well as greater flexibility in vessel design.

The 8HD's major benefit is said to be its outstanding fuel efficiency, coupled with ease of routine mainte- nance. Available options include a power takeoff unit, keel cooling, and change-over filters. This new engine complements the 12-cylinder Rolls-

Royce design introduced last year.

The 12HD610T diesel is a 60-degree

V-form, water-cooled engine that provides 735 bhp at 2,100 rpm for (continued)
