Timely find after our recent hurricanes and numerous posts here on using a Pri for home generating power. "Junk yard 2nd generation Prius engine into a home generator set because I could and it was a challenge to myself. Removed final drive cvt belt and gears and welded power split device sun gear to lock outer motor mg2 to get 120v ac at idle. This thing will never go back into another car anyway. This engine runs on the 2001 Toyota echo ecu, not the Prius due to complexity and cost of components. The engine it self is running in limp mode mainly because I don't have an idle air control wired up and I really don't need it. I only needed the ecu for spark control and injector cycling but thinking about Arduino for injector control in the future. The engine is started on a car starter because I don't have the prius components or battery pack. I cut the transmission case on the side using a saw+zza and used an automatic flex plate and bolted the flywheel on top of it to lock the transmission shaft into place. I use zinc washers for spacing the transmission and engine to fit the "output shaft stack". This is an engineered build and welded this square tube frame with a 120v welder, its strong and moves easy with the dolly tires but still needs to be finished up."
What happened to MG1? What is the output frequency vs ICE rpm? Did you leave the coolant channels? Plans for power electronics? GOOD JOB! I look forward to progress reports. <GRINS> Bob Wilson
