Awhile ago we were having a technical discussion about ICE shutdown. It's been commonly claimed on PC that the Prius ICE rotates to a preferred position when turning off, sometimes leading to the engine shudder felt at ICE shutdown. When this idea was challenged, none of us could produce any documentation. Have any of you come across any documentation that verifies the preferred position shutdown? Tom
...wherein it is written: "In order to eliminate shock during engine start-up, the generator also precisely controls the stopping position of the engine's crank."
Thanks for providing the link, David. I was wondering about the source for that commonly-accepted wisdom.
Original thanks should go to ken@japan. He posted it over a year ago. I used it, suitably reformatted for printing, plasticized the printouts, and carry them in a binder when I attend car shows. Another newer and spiffier Toyota info. link, but with a little less info. though more wide covering (includes info on the Highlander Hybrid and Camry Hybrid) is at: HYBRID SYNERGY DRIVE: Technology Click on the pdf link at the top of the page for a full listing of what's there.
