A Woodward "spin out." Cummins playing with Federal Money.

These VanDyne illustrations go back to 2008.

The attempt here is to deal with diesel engines inability
to accelerate with out large clouds of black smoke.

At Le mans 24 hours they use a smoke filter. Tractor pulling
contest well illustrate the problem with clouds of
black smoke blocking out the sun.

Detroit Diesel gets around the problem by using
a turbo charger separated from the power turbine.

Cummins is looking for their own solution and trying to catch
up with DD. I think the performance claims are exaggerated. Obama and
the Congress will not care. Any old excuse to spend/waste money
is all they need.

In this case Ed Vandyne is trying to do it with
the turbo charger turbine. One turbine.

Merely taking power out of the turbo charger shaft will work
in an aircraft or boat engine as turbine acceleration is
of no consequence.

We addressed the variable speed issue years ago,
