The blowers and camshafts are at the "rear" end of the engine, with the blowers mounted above the power take off. [8] All engines have mechanically-controlled unit injectors (patented in 1934 by General Motors, EMD's former owner). All 567 engines use forced induction, with either a Roots blower or a turbocharger. The turbocharger (a ...
An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
The EMD MP15, sometimes referenced as MP15DC, is a 1,500 hp (1,119 kW) diesel–electric road switcher locomotive model produced by General Motors' Electro-Motive Division between 1974 and 1980. It was equipped with a V12 12-645E engine sporting a Roots blower. The length was either 47 ft 8 in (14.53 m) or 48 ft 8 in (14.83 m) depending on the ...
The rotor form is cycloidal, and in this drawing is drawn accurately. In fact, it is part epicycloidal and part hypocycloidal, and in both cases the smaller generating circle is 1/4 the diameter of the circle it rolls around. Roots blowers find uses in superchargers and gas pumps which need a high volume at a low differential pressure.
But, unlike the earlier 645 and 567, which could use either turbochargers or Roots blowers, the turbocharger is a standard feature of most 710 models. Horsepower for any naturally aspirated engine is usually derated at 2.5% per 1,000 feet (300 m) above mean sea level, a penalty which becomes extremely large at altitudes of 10,000 feet (3,000 m ...
It is a mechanically injected two-stroke diesel engine that used a Roots blower. The 16-184A was installed in some 110-foot (34 m) subchasers of the SC-497 class during World War II. The two 1,540 bhp (1,150 kW) 16-184A diesel engines driving two shafts produced a faster subchaser that achieved 21 knots.
The EMD GP15 is a 4-axle diesel-electric locomotive built by General Motors Electro-Motive Division between June 1976 and April 1983. Intended to provide an alternative to the rebuilding programs that many railroads were applying to their early road switchers, it is generally employed as a yard switcher or light road switcher .
An EMD SW1200 is a four-axle diesel switcher locomotive built by General Motors Electro-Motive Division between January 1954 and May 1966. [1] Power is provided by an EMD 567C 12-cylinder engine, which generates 1,200 horsepower (890 kW). Additional SW1200 production was completed by General Motors Diesel in Ontario, Canada, between September ...
