Summary:

AbstractIn response to increasing demands for measures to conserve the global environment and the introduction of more stringent CO2 emissions regulations around the world, the automotive industry is placing greater focus on reducing levels of CO2 through the development of fuel-efficient technologies.With the aim of improving fuel economy, a new continuously variable transmission (CVT) has been developed for 2.0-liter class vehicles.This new CVT features various technologies for improving fuel economy including a coaxial 2-discharge port oil pump system, wider ratio coverage, low-viscosity CVT fluid, and a flex start system. This CVT is also compatible with a stop and start (S&S) system that reduces fuel consumption by shutting off the engine while the vehicle is stopped.In addition, the development of the CVT improves driveability by setting both the driving force and engine speed independently. Quieter operation is also achieved by measures such as the adoption of a newly developed soundproofing cover and a revised belt arrangement to reduce the vibratory force that causes belt noise.This paper outlines the configuration and new technologies of this CVT
