With 12 or 16 cylinders .03 s 16'<4 in.), they cover a range (rare 2400 to 4260 hp at 4S0 to 600 rpm. Built (or liquid lue). dualuel er aparkfired gas operation, design incorporates all performance features of 13-in. bore in-line Supof/iAermo/ engines. Many of the im portant parts of the V-type engine are Men- sseal and interchangeable wlih in-line-type parts. Included angle of oylinder bonks is 45 degrees, offset between cylinders on eteh crankpln is 4% in. Net weight of 12-cylinder engine it 96,000 lb, end of I6>cylinder, 122,000 lb, not including flywheel and ex. lenafon abaft. Inlet air manifold and aingle-duct exhaust manifold are directly under housing of 2pass Intercooler which runs full length of the engine. For italionary ore, turbocharger ia at free end, for marine use, at drive end. Counterweighted crankshaft is carried in the frame, supported by lower transverse members. Steel bearing'caps are keyed to these members and held in place by two atecl through,bolts. Heat-treated alloy steel Is used in engine frame, bedplate, crankshaft, connecting rods, etc. Frame is welded and stress re lieved. Kemovahle cast-iron cylinder liners seat in individual cast-iron jackets. This permits directed flow of cooling water. Entire cyl inder assembly with liner is easily remov able without disturbing liner water seals. Exhaust and Intake valves seat directly in cylinder heads for maximum cooling. All moving parts are pressure lubricated. Rotary tubriceiing-ol( pumps are driven by roller chain from end of crankshaft For oil operation, a constant-stroke fuel, injecilen pump of variable cut-off type Is used. Easily removable fuel nonle holders have spring-loaded vslves snd multiple-bole tips. For duafuel er spark-ignition opera tion a hydraulically-actuated gu admission valve it used. For spark-firing there are alto rwo spark plogs per cylinder and lowtension impulse generators, rectifiers and transformers. Each engine has hydraulic, relay overspeed and control governors mounted at the flywheel end. Engine it suited for continuous operation In many atotlonary applications. The ma rine engines arc available in direei-reveraing types (or direct drive, tingle or multiple drivo through reduction gears with electric or hydraulic couplings or for dieoel-clectrio drive.

It it claimed to resist weather, corrosive chemicals, water, oils and abra sion. Tape is eitru thin with high tensile strength and adhesive qualities, and Is,said to conform readily to irregular surfaces. Dielectric strength averages over 1000 volt* per mil of thickness, meeting UL specifica tions.

To the left is a close-up of tho firing aisle, showing the spreader, stoker and the main control panel. Cool handling Is automatic and dusttight throughout. Automatic controls regulate firing, drafts and feed-water--give maximum efficiency at lowest cost. Burning cool tho modern way.can save you money, tool First, labor costs can be cut to a minimum with up-to-date coal- and ash-handling equipment. On top of that, today's combustion nstallations give you 10 to 40% more power from each ton ofcoal than was possible a few years ago! If you're planning to modernize, or if you're building a new plant, call in a consulting engi neer. He'll show you how you can get big savings by burning coat in a modern plant designed to meet your specific needs. America's coal reserves are virtually inexhaust ible; America's coal industry is the world's most. productive and efficient. That's why coal has a future dependability of supply that no other fuel can offer. That's why, of all fuels, the price of coal is most likely to remain stable.
