I recommend that you google "prius atkinson cycle" or just "atkinson cycle"
to get an idea of how the idea works.  their description is much better than
what I'd come up with.

Regular engines don't have a "starter" that's strong enough to repeatedly
spin-up the engine.  The MG1 in the Prius is not only a starter, but it's
also a generator, and part of the traction motors.

It turns out that GM of all people is way ahead in devloping hybrid
diesel - in buses. the following links tell the story - diesel, hybrid,
regenerative braking - the lot! 60% gain in economy.




I owe it to an Australian electronics magazine - Silicon Chip - which
is running an article in its June issue on this GM - Allison project
which is not pie in the sky - the vehicles are operating in various
parts of the US.

covering the weaknesses of the other. There is no

and 80 mpg on the freeway, at least at 65 mph.

cranking torque, so you'd need more powerful motors

'bumped' as its low compression.

Nope.  The VW diesel uses the same starter as the gasoline model,
about 3 hp.  A 20 to 50 kw motor will easily spin the diesel motor.

I get better mileage than that with my Prius, burn less expensive fuel, and
my exhaust emissions are cleaner.  What's your point?
