However, because 6–71 is the engine's designation rather than that of the blower, the actual displacement of the blower is less; for example, a 6–71 blower pumps 339 cu in (5.6 L) per revolution. Other supercharger manufacturers have produced blowers rated up to 16–71.
Supercharger: Single-speed General Electric centrifugal type supercharger, blower ratio 7.134:1; Fuel system: Stromberg PD12K10 downdraft carburetor with automatic mixture control; Fuel type: 87 octane rating gasoline; Oil system: Dry sump with one pressure and one scavenging pump; Cooling system: Air-cooled
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.
Distancing the supercharger from the engine via a mounting bracket greatly reduces heat transfer from the engine to the supercharger during operation. By comparison, a twin screw or roots blower which is nested in the center (valley) of the engine, will absorb heat (heat soak) during operation due to thermal transfer from the engine block and ...
Supercharger: Two-speed two-stage, boost pressure automatically linked to the throttle, water-air aftercooler installed between the second stage and the engine. Fuel system: Twin-choke updraft carburetor with automatic mixture control; Fuel type: 100 Octane, from mid 1944 100/150 Grade Aviation fuel
Oil system: Pressure fed at 60–70 psi (414–483 kPa), dry sump with one pressure and two scavenge pumps. Cooling system: Liquid-cooled with a mixture of 70% water and 30% ethylene glycol, pressurized. Reduction gear: Spur reduction gear, 0.5:1 ratio, right hand tractor (V-1710-F30L / -113 is the same engine with LH rotation)
When the rotating speed of the engine is sufficient to pull in enough air to support combustion, fuel is introduced and ignited. Once the engine ignites and reaches idle speed, the bleed air and ignition systems are shut off. The APUs on aircraft such as the Boeing 737 and Airbus A320 can be seen at the
The term "blower" is applied to rotary screw, roots-type, and centrifugal compressors when utilized as part of an automotive forced induction system. The term 'cabin blower' is also used for the pressurisation of aircraft for high altitude flight, which used Roots type compressors particularly in the 1950s (see Marshall supercharger).
