American Experience with BUCHI TURBO - CHARGING 410129

THIS paper reviews briefly the background of the adoption of the Buchi turbo-charging system in the United States, particularly with reference to the American Locomotive Co. and the Cooper-Bessemer Corp. who were most active in sponsoring it. Broad design considerations are discussed, concerning the requirements for best results with the use of this type of supercharger. Performance curves covering several makes of engines are included, and special characteristics of the turbo-charged engine are discussed. The paper also contains a brief description of turbo-charger units of American manufacture.
In remarks concerning the probable trend of future supercharging developments, the authors predict that the four-cycle supercharged diesel engine is on the verge of rapid evolution toward a substantial reduction in specific weight and space, to be accompanied by considerable research and field operating experience.
Tests reported show that a turbo-charged diesel engine will carry suddenly applied full load in the same manner as will the unturbo-supercharged engine. No additional maintenance difficulties or costs are encountered with turbo-charged engines, the authors contend.
