Re: Ways to reduce engine cost in hybrids?
___Nice post … Could you please explain what the patent(s) are in your posts as I do not want to look them up and try and deduce what is being patented with a Patent Attorney’s write up trying to cover every base under the sun.
___I want to make a few comments. Most hybrid’s (Prius I/II, HCH-I/II, and Escape HEV) use what I would call an inexpensive ICE to begin with. The last time I read, Ford’s 4-valve per head - 2.3L ICE used in the Ranger, Focus, and Escape cost just $1,200 complete as outsourced out of Mazda’s Hiroshima plant a few years ago. I have no idea what the complete 2.3 ICE assembly’s coming out of the Dearborn Assembly cost but I doubt it’s that much higher if at all. The Escape HEV’s Atkinson intake is more of an intake valve timing tweak rather then a complete redesign of the heads and intake plenum IIRC. This is the whole ICE package including the head, block, crank, rods, pistons, controllers, injectors, and everything else ready to bolt to the tranny. A cast iron head vs. the aluminum one is a few $’s less but this is not the expensive part of today’s hybrid’s/non-hybrid’s given a $1,200 price tag for the whole ICE package vs. the same or higher for an outsourced pack from Panasonic or Sanyo. The pack, multiplexed controllers, multi-frequency capable MGSet’s, and inverter/up-converter are where the real expenses lye I would have to assume?
