A short video on the directorstalk.com website posted on 20 April 2013 in conjunction with Volvo Cars highlights the benefits of the Torotrak/Flybrid Kinetic Energy Recover System (KERS).
The flywheel KERS is fitted to the rear axle. During retardation, the braking energy makes the flywheel spin up to 60,000 rev/min. When the car starts moving off again, the flywheel’s rotation is transferred to the rear wheels through a specially designed transmission.
The fuel consumption can be reduced by some 25 per cent. Also, the power of the engine is boosted and the car’s acceleration improved.
The video explains that the work is the result of a research project carried out in conjunction with Volvo Powertrain and SKF. No mention is made of Torotrak, which as designed an infinitely variable transmission (IVT) or Flybrid Automotive of Silverstone which has developed KERS using flywheel energy capture.
As reported already in autoindustrynewsletter.blogspot.co.uk Flybrid is working closely with Volvo Cars and the outcome could materialise in a production programme. ∎
