Abstract
Technologies for reducing fuel consumption have attracted strong interest in recent years amid the heightened concern about global environmental protection. At Nissan, we have been focusing on the development of electronically controlled continuously variable transmissions (CVTs) since the early 1980s as a promising technology for reducing fuel consumption. That work has led to the commercialization of the world's first belt-drive CVT that is suitable for application up to 2.0-liter class passenger cars.
The practical use of CVTs has so far been limited to cars mounted with small displacement engines of the 1.6-liter class. The belt-drive CVT described here incorporates new technology for transmitting greater torque and also has product attributes suitable for use on upscale passenger cars, making it applicable to 2.0-liter class models.
