Electrical on demand supercharging provides an internal combustion engine with the facility to increase its volumetric efficiency without being subject to the mechanical constraints associated with a conventional pressure charging device. This enables improvement in fuel economy through engine downsizing with the added ability to enhance torque. The Visteon Torque Enhancement System (VTES) is a...

Testing is absolutely essential to the product development process, and the need to test supercharger products is no different. On the technical side, the development engineer must know if his design and product execution meets specifications. For example, were his initial assumptions correct? What about modeling and simulations conducted during the design process – were these calculations corr...

A new mechanical supercharger-a low compression ratio scroll compressor was introduced in this paper, including the principle, scroll geometry, suction volume, inner compression ratio, etc. Then the advantages of the scroll supercharger were pointed out compared with other superchargers. After some concrete design considerations, a prototype was made and the performance tests showed the results...

The supercharger is intended for heating a fluid (gaseous helium or gaseous nitrogen) used the pressurization of fuel tanks oxidizer and propellant rocket engine. heated with generator gas downstream turbine. A increased channel surface roughness was made according to an additive technology. High one features producing parts by selective laser melting. article presents method calculating heat t...

Next level of passenger vehicles engines evolution is needed to comply with fuel economy and pollutant regulation legislative requirements. Turning a combustion engine with modern control systems into reverse uniflow two-stroke engines improves the power density of the engine and minimizes negative aspects of using the classic two-stroke engines. Variable valve timing allows control of the inta...
