With Ford's withdrawal from F2 in the mid-1970s, Hart began to concentrate on building their own designs. The first engine to bear the Hart name alone was the twin-cam, four-cylinder Hart 420R F2 unit, which appeared in 1976 and powered race-winning cars until the end of the decade. In 1978, the Toleman team agreed to a partnership program ...
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.
An electric supercharger is a specific type of supercharger for internal combustion engines that uses an electrically powered forced-air system that contains an electric motor to pressurize the intake air. By pressurizing the air available to the engine intake system, the air becomes more dense, and is matched with more fuel, producing the ...
A more successful application was in the RF series diesel engine found in the 1988 Mazda 626 Capella; ultimately 150,000 Mazda diesel cars were fitted with a Comprex supercharger. Other users included Peugeot, Opel and Mercedes-Benz. The Greenpeace SmILE concept car uses a Hyprex pressure wave supercharger developed by the Swiss company Wenko ...
In March 2004, the company was acquired by management and changed its name to Hart Energy Publishing, LP. [2] In October 2010, Hart Energy acquired Rextag Strategies Mapping & Data Services.

The scroll-type supercharger is a scroll compressor used as a positive displacement orbiting-spiral supercharger. It is a compromise between the more rugged rotating lobe, and the more efficient sliding vane type superchargers, and is considered to offer the highest potential in regard to efficiency, noise and pressure fluctuation.
That drug, in combination with new laws and the women’s rights movement, supercharged female participation in work and public life. Between 1970 and 1980, the number of women in law schools more ...
The Shorrock/Centric supercharger is the type with sliding vanes, which by an efficient arrangement are able to travel very close to the walls of the compressor without making contact, thereby allowing greater maximum velocity and reducing lubrication requirements compared to earlier types that contacted the walls.
