NEW EQUIPMENT Ampul 320 hp; 0375, V8 engine with' blower, maximum output 334 bp, rated output 300 hp and continuous output 266 hp; 0364, a V0. minimum .output 267 hp, rated output 240 hp and continuous output 214 hp. --All four engines are designed for 100% power takeoff at either end. Parts are interchangeable between eoginea of like number of cylinders. Lubrication, fuelinjection, cooling and starting systems are similar in all four units, as ere the governor flywheel housing, crankshaft and bearings, connecting rods, pistons and rings, cylinder liners and head, valves and cylinder block. Choice of electric or air sterling Is offered. Crankshaft Is drop-forged high-carbon steel with hardened journals. Drop-forged steel connecting rods have crsnkpln bear ings ol solid aluminum alloy and precision* ' bored bronse wristpio bashings. Main hearings are also precision type, of solid aluminum alloy. Trunk pistons are alumi num alloy with three compression and two oil rings. Full-floating carburised end hardened ground piston pins are provided. Removable wet-type hardened alloy-castiron cylinder liners are chemically treated for superior "breek-in.M Single inlet ond exhaust .valve for each cylinder are of in head type. Engines are full pressure lubri cated. A gear transfer pump supplies fuel through replaceable absorbent biters to 'individual fuel-injection pumps with the fuel delivered under pressure to the singleorifice fuel-injection valves. A hand-oper ated pump permits priming the fuel system before starting the engine.

Pressure Indicator E420 Heart or the Atcothan system is based on applying a differential transformer, which develops a linear outpul, (q stand ard primary measuring elements such as bourdon lubes r bellows. The indica tor eliminates objectionoble inherent char acteristics of the bourdon tube because tube it not loaded with instrumentation gear. Only armature of the differential transformer is connected to tube tip. There arc no jewel bearings, pivots, springs or similar movements. The lubes, which may be loaded to full rated range, consistently return to zero position within occuracy limitation of the Atcotrsn system. Instru ments are accurate to within one-quarter of 1% reading; sensiiivity Is one part in 4000, or better.
