Comfort, Performance, Environmental Protection: Powertrain Components and Systems for Passenger Cars The demands placed on suppliers in the automotive sector are changing dramatically. Increasingly, suppliers are being called upon to integrate components into complex systems – a development task that can only succeed on the basis of close partnerships with vehicle manufacturers. The future will bring continued demands for reduced fuel consumption, emissions, weight and installation space, along with enhanced comfort, safety, and driving dynamics. To meet these goals, innovative solutions and...

The Important criteria include lower fuel allow two gears to be engaged at the same time. One of the gears reduce energy loss as much as possible. The dual clutch system consists of two separate clutches, which to enhance power transmission and to Development work on the driveline aims Designs of...
