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.
In 1875, Roots exhibited a blower at the Saint Petersburg Exhibition; Thwaites and Carbutt exhibited a Roots principle "air blowing machine" for mine ventilation in the same exhibition. [ 6 ] In 1885, Edgar Dwight Johnston joined the firm of 30 people; he became vice president in 1889 and president in 1898, remaining so until at least 1931.
A lobe pump, or rotary lobe pump, is a type of positive displacement pump. It is similar to a gear pump except the lobes are designed to almost meet, rather than touch and turn each other. An early example of a lobe pump is the Roots Blower , patented in 1860 [ 1 ] to blow combustion air to melt iron in blast furnaces, but now more commonly ...

The blower is usually of the Roots-type but other types have been used too. This design is commonplace in CI engines, and has been occasionally used in SI engines. CI engines that use a blower typically use uniflow scavenging. In this design the cylinder wall contains several intake ports placed uniformly spaced along the circumference just ...
Instructions. Add the eggs to a medium sauce pot and fill it with enough water to cover the eggs. Set the sauce pot over medium-high heat and bring the water to a boil.
The Roots supercharger dates back to the 1860s, and this is the basis for the original Wade supercharger, but with patented modifications incorporated. The first patent of Costin and Densham deals with ways to achieve compression within the Roots-style blower. [ 2 ]
