Electrically driven compressor also known as E-compressor or E-booster is one solution to compensate the turbo-lag on a turbocharged engine. This paper deals with the development of such a device and its effect on the engine. Target for this design will be a pressure ratio of 1.3 within 300ms. The electromagnetic motor structure used for this development and adapted to high speed will be shown as well as its optimization process. Results of the measurements of this e-booster will be presented and analyzed. These measurements will range from the motor itself to the e-booster impact on the engine. Indeed, on-engine test may help to better apprehend the impact of such a system on a real engine. The good agreement between measurements and simulation will be shown as well as the improvement obtained by the e-booster on the engine performances.

INGENIEURS DE L'AUTO SE DIGITALISE

 

 

La revue Ingénieurs de l’Auto est maintenant diffusée en print et on line. Une grande première pour la SIA avec ce numéro 865, disponible au format numérique.

Cette version digitale sera, à chaque numéro, réservée aux membres de la SIA abonnés.

Exceptionnellement pour ce premier numéro on line, et en lien avec la situation de confinement et de télétravail de beaucoup d’ingénieurs de notre industrie, la version digitale du numéro de Mai est accessible à tous.
