Abstract
(EN)
Devices and methods for improving fuel efficiency are disclosed herein. According to aspects illustrated herein, there is provided a device for improving fuel efficiency of a combustion engine. The device may include a housing for attachment to an exhaust pipe of a combustion engine and having a pathway extending therethrough. The device may further include a wound body disposed at a distal portion of the housing and designed to permit fluid from the exhaust pipe flowing along the housing to flow through the wound body. In addition, the device may include a barrier positioned within the pathway downstream from the wound body so as to generate a sufficient back pressure along the exhaust pipe to enhance piston stroke efficiency in the combustion system, resulting in an increase in fuel efficiency of the combustion engine.

La présente invention se rapporte à des dispositifs et à des procédés permettant d'améliorer le rendement énergétique. Selon des aspects illustrés, la présente invention se rapporte à un dispositif destiné à améliorer le rendement énergétique d'un moteur à combustion. Le dispositif peut comprendre un logement destiné à être fixé à un tuyau d'échappement d'un moteur à combustion et ayant un passage s'étendant à travers ce dernier. Le dispositif peut en outre comprendre un corps enroulé qui est disposé au niveau d'une partie distale du logement et conçu pour permettre au fluide de s'écouler depuis le tuyau d'échappement le long du logement à travers le corps enroulé. De plus, le dispositif peut comprendre une barrière positionnée dans le passage en aval du corps enroulé de sorte à générer une contre-pression suffisante le long du tuyau d'échappement afin d'améliorer l'efficacité de la course des pistons dans le système de combustion, ce qui a pour résultat une augmentation du rendement énergétique du moteur à combustion.
