and all engines can run on the same type of heavy fuel.

The ability to burn heavy fuel successfully lies in a purpose-de- signed diesel engine and fuel-han- dling system. Wartsila's heavy fuel engines feature: increased pre- heating of the engine before start- ing, including jacket water, lube oil, charge air, fuel system on both the high- and low-pressure side, and fuel nozzles; increased filter capacity of both fuel oil and lube oil; higher temperature and im- proved insulation of the injection pump control system.

Wartsila Diesel is represented through its own subsidiaries and agents in 30 countries. The com- pany's after-sales service is based on a worldwide network of trained specialists. Operators and mainte- nance engineers are trained on- site and at the Wartsila factories.

Since 1980, Wartsila Diesel has been represented in the U.S. by

Wartsila Power Inc., with offices in New Orleans, Houston, and

New York. On the U.S. West Coast, the company is represented by

Southwest Marine, Inc. of San

Diego.

WAUKESHA

Waukesha Engine Division of

Dresser Industries, Waukesha,

Wise., has produced more than 40,000 horsepower of its new AT25 diesel since signing a license agreement with Sulzer Brothers

Limited of Winterthur, Switzer- land, several years ago.

This production follows a mul- timillion-dollar capital investment in plant renovation and new ma- chine tools to build these heavy- duty, four-stroke, medium-speed diesels. They deliver from 1,140 to 4,800 bhp (metric) in in-line six- and eight-cylinder, and V-12 and

V-16 cylinder configurations.

The AT25 is capable of operat- ing on heavy, blended, and distil- late fuels. This range is made pos- sible through a design that incorporates oil-cooled injection nozzles, bore-cooled cylinder heads, exhaust value rotators, two-piece pistons, and turbocharger washing equipment.

A rugged yet compact engine, the AT25 is conservatively rated and offers excellent access to com- ponents for ease of service. Quick- opening access covers are provided for such components as camshafts and mail bearings. A provision for fast removal of rocker arm covers facilitates valve adjustments.

Water, lube oil, and fuel transfer pumps are located on the front of the engine for easy access. For maintenance, hydraulic tension- ing of main bearing cap studs, cyl- inder head studs, and connecting rod studs insures precise preload- ing and cuts assembly time.

WICHMANN DIESEL

Circle 26 on Reader Service Card

Wichmann Diesel, Inc., of Ken- ner, La., offers a line of fuel saving low speed diesels from 1,140 to 4,220 hp, with engine speeds from 300 to 475 rpm.

Wichmann states specific fuel consumption for their line of die- sels is one of the lowest in the world. Simplicity of design reduces both planned and corrective main- tenance. In addition, any neces- sary maintenance requires less time than with more complex pro- pulsion systems.

All engines are two-stroke.

Models are available for reduction gear application or as a complete system directly connected to a

Wichmann controllable pitch propeller.

Of in-line design, models are available in four to 10 cylinder configurations. They are loop sca- vanged, have no exhaust valves, require only standard instrumen- tation and controls. Other common features include water cooling, di- rect injection and turbocharging.

Spare parts are interchangeable throughout the entire Wichmann engine line providing ease of maintenance and a minimum spare parts inventory.

Westfalia Oil Purifiers are also used for lube oil purification. This is espe- cially important when diesel engines operate on heavy fuel oils.

With capacities up to 5300 gph (depending on viscosity), Westfalia

Oil Purifiers offer top efficiency and highest reliability. They provide what diesel-powered boats need: less engine downtime and engine wear— and substantial extra savings as lube oil life is extended.

Typical Westfalia Fuel Oil Purification System (for viscosities up to 6000 SRI/100°F).

Centri-Pack module incorporates two OSA self-cleaning Oil Purifiers.

This system is in operation on the Bill Elmer, a repowered 180-foot push- boat owned by American Commercial Lines.

Westfalia Oil Purifying

Systems

On inland and offshore vessels, heavy fuel oil is the shape of the future, replacing more expensive diesel oil.

Because heavy fuel oils must be purified prior to combustion,

Westfalia Oil Purifying Systems are indispensable. The heart of the

Westfalia Oil Purifying System is the automatic self-cleaning oil purifier, type OSA. It removes water and solid contaminants such as cat- fines, rust, etc.—contaminants that, if allowed to remain, cause extensive wear and serious damage to engine components.
