Variable-speed hydraulic-power,-; transmissions using positive-dischargs variable-displacement piston pumps are studied for speed range, physical sim. rating, hydraulic circuits, volumetric \ efficiency, fluid compressibility, out put torque, torque efficiency, pompstroke control, noise levels, failure oi hydraulic equipment to perform, and operating temperature range. These factors indicate that requirements should be carefully analysed before lecting a variable-speed unit, to obinb best possible application of hydraulic equipment. NCfH paper.

Here's how its done: Typo "S" Dietel Engine! ore built in 77S fo 600 hp it`es. "Super 5" turbocharged en gine* range /rom 67S to 900 hp. All i/ti operate at 770 tpm. Moving upward around tho cylinder, cooling water It lorced through two reduced cAanne/i encircling the top oI the cylinder. This INCREASED VELOCITY means more heat pickup as all heat tranaler engineers know: Leaving the cylinder fackete, cooling water it carried to tho cylinder head by a thort Jumper which dlrectt the water across ifi* "door" of tho cylinder head and around the reive teaft. Here again, directed cooling improves heat pickup. ' Much eredit for the outstanding performance records of Type "S" Engines is due to this advanced cooling system design. With the other Type '*S" features such as twin-fuel injection end full force-feed lubrication, these 4-cycle engines offer unusual value to Diesel users. Jngenf11-RancL n bsoaoway, nsw row a, n. r.
