Engine downsizing is the bigger picture for off-highway machines

Project Highlights

  • Led from Caterpillar’s Wolverhampton facility and will involve consortium partners UK facilities in Peterborough, Desford, Silverstone and Hatfield Hertfordshire.
  • Scaling Continuous Variable Transmission (CVT), typically utilised in larger off-highway machines to the smaller machines greatly improves efficiency
  • Coupled with an Energy Storage System (EES) these improvements will enable improved performance.
  • This innovative approach enables engine downsizing, offering significant reduction in fuel consumption and CO2 emissions and importantly, reduces cost of ownership
  • Includes a low-cost flywheel into the highly integrated drivetrain, developed by Punch Flybrid, UK
  • Total project value £8.2 million with half funded through the APC

Scaling new heights of CVT architecture reduces CO2 emissions

Project delivers engine downsizing that can be deployed in a range of off-highway machines, delivering advantages including significant improvements in fuel consumption together with lower CO2 emissions. This improved performance is achieved, not least, through an innovative flywheel based energy storage system.
