- Q602696 abstract "The EMD 567 is a line of large medium-speed diesel engines built by General Motors' Electro-Motive Division. This engine, which succeeded Winton's 201A, was used in EMD's locomotives from 1938 until its replacement in 1966 by the EMD 645. It has a bore of 8.5 in (216 mm), a stroke of 10 in (254 mm) and a displacement of 567 cu in (9.29 L) per cylinder. Like the 201A, the EMD 645 and the EMD 710, the EMD 567 is a two-stroke cycle engine. It is a V engine with an angle of 45° between cylinder banks (the 201A was 60° between cylinder banks; 45° later proved to be significant when EMD subsequently adapted the road switcher concept for most of its locomotives, and which required the narrower (albeit taller) engine which 45° provides). The 710, 645, and 567 are the only two-stroke engines commonly used today in locomotives. Eugene W. Kettering, son of Charles F. Kettering, joined Winton Engine in 1930. He moved to Detroit in 1936, and was a central figure in the development of the 567 and the Detroit Diesel 6-71. He moved to EMD in 1938, became Chief Engineer at EMD in 1948, then Division Director in 1956 and subsequently Research Assistant to the General Manager in 1958 until his retirement in 1960.In 1951, E. W. Kettering wrote a paper for the ASME entitled, History and Development of the 567 Series General Motors Locomotive Engine, which goes into great detail about the technical obstacles that were encountered during the development of the 567 engine (these same considerations apply to the 645 and 710). The 567's designers started with a tabula rasa, 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 645 and 710, which are not materially different from the 567 (all have the same external dimensions, differing mainly in per cylinder displacement), collectively have given nearly 80 years of exceptionally reliable service to those applications. As but one example of the achievements of the tabula rasa design: whereas the Winton 201A was doing very well with a 50,000-mile (80,000 km) to 100,000-mile (160,000 km) piston lifetime, the 567 eventually achieved a 1,000,000-mile (1,600,000 km) piston lifetime, a 10:1 to 20:1 improvement.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 power assemblies, theoretically achieving an increase in horsepower, but not without corresponding changes to the engine's Woodward 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.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 governor, hence without a corresponding power increase.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.EMD's chief competitor, GE, now makes EMD-compatible replacement parts.".
