EMD 567 - Knowledge

786:. The turbocharger (a combination turbo-compressor system) follows EMD's innovative design that uses a gear train and over-running clutch to drive the compressor rotor during low engine speed, when exhaust gas temperature (and, correspondingly, heat energy) alone is insufficient to drive the turbine. At higher engine speeds, increased exhaust gas temperature is sufficient to drive the turbine and the clutch disengages, turning the turbo-compressor system into a true turbocharger. The turbo-compressor can revert to compressor mode momentarily during demands for large increases in engine output power. While more expensive to maintain than Roots blowers, the turbocharger significantly reduces fuel consumption and emissions, while improving high-altitude performance. Additionally, EMD's turbo-compressor can provide a 50 percent increase in maximum rated horsepower over Roots-blown engines for the same engine displacement. 681:, systematically eliminating each of the 201A's many deficiencies which were preventing the earlier design from becoming successful in freight service, although the 201A was relatively successful in the less-demanding passenger and switching services. The 567 design had nothing in common with the 201A except the two-stroke cycle itself: each and every component of the 201A was replaced with a new design, even the "dipstick", to paraphrase one of Kettering's off-handed comments. The 567 proved to be exceptionally successful in passenger, switching, freight, marine and stationary services, and, counting its two successors, the 176: 707: 740: 1386: 74: 1394: 33: 2517:"In 1946 a new line of crankcases, designated as the 567B, were introduced which were basically the same as the 567A except for a change to permit the mounting of the auxiliary generator drive gear. About three or four months after the introduction of the "B" engine the cylinder head retainer castings, which had been a continuous source of production problems, were replaced with steel forgings." 254: 828:

567 gave way to the 567A in 1941, which incorporated further top deck improvements and camshaft gear train changes. The 567B followed in 1946 with minor improvements. The 567C was released to further improve reliability and manufacturability. Visually, the 567C may be distinguished from earlier models by the presence of round (instead of square) handholes.

governor which activates and controls the engine's "fuel rack". Although this power increase is not recommended, horsepower-for-horsepower updates (e.g., 2,000 hp or 1,500 kW 567D to 2,000 hp or 1,500 kW "645D"—645 power assemblies in a 567 block) are quite successful and common.

827:

Numerous early improvements were aimed at increasing reliability and life, including a switch from the U-shaped top (exhaust) well to a V-shaped top well. This eliminated the cast top deck, which had been the source of some early-life failures, in favor of a top deck fabricated from plate steel. The

is perhaps the least maintainable part of such an engine, and the 567D turbo has many more maintenance issues than 645E and later turbos. A common choice is conversion of a 567D turbo engine to Roots-blown, thereby abandoning the turbo and its many issues. Installation of 645 power assemblies will

201A was doing very well with a 50,000-to-100,000-mile (80,000 to 161,000 km) piston lifetime, the 567 immediately achieved a 400,000-to-500,000-mile (640,000 to 800,000 km) piston lifetime, and in at least one case, reached a 1,000,000-mile (1,600,000 km) piston lifetime, a 10:1 to

567AC engines (an "A" block upgraded to "C" block specifications) and 567BC engines (a "B" block upgraded to "C" block specifications), both of which modifications eliminate the engine's "water deck" and substitute a "water manifold", as well as 567C and 567D engines, may be upgraded to use 645

814:

As 645 power assemblies are more readily available than 567 power assemblies, this upgrade may also be employed in so-called "life extension" programs, in which case the power assemblies would be upgraded, and the engine may be de-turbo-ed, without corresponding changes to the engine's Woodward

The locomotives are based on the EMD F7. It was designed for DSB, Denmark as Class MY and was first built in 1954, with number 1101 to be the first unit of all AA16's. Later exported around Europe as Di3 (NSB, Norway) and M61 (MAV, Hungary), 202 (SNCB, Belgium) 1600 (CFL, Luxembourg).

The 567 is laid out with engine accessories (oil and water pumps and governors) at the "forward" end and the power take off at the "rear" end. The blowers and camshafts are at the "rear" end of the engine, with the blowers mounted above the power take off.

Because of their age, 567 engines are generally exempt from emissions rules. EMD manufactures a special series of 645 power assemblies which are particularly useful in updating these exempt 567 engines and also certain exempt 645 engines.

The 567 was released in 1938. 2254:) to produce 2,000 hp (1,500 kW), as does a Roots-blown 16-645E, thereby becoming the functional equivalent of a GP38, although with older electrical equipment and controls, and, of course, the older carbody. 2257:

Many EMD locomotives with C and D engines are still operating, particularly as their relatively light weight (about 260,000 pounds or 120,000 kilograms) is of significant benefit to shortline and industrial operators.

Marine engines differ from railroad and stationary engines mainly in the shape and depth of the engine's oil sump, which was altered to accommodate the rolling and pitching motions encountered in marine applications.
