It shows, using idealised pressure - volume diagrams, how significant improvements in fuel economy can be made by implementing
a throttleless load control strategy.
This section compares ideal and realistic valve motions for
throttleless load control, showing the reductions in pumping work that are feasible with the use of a variable lift and duration VVA system.
Not exact matches
