One thing I have not seen much discussion on is exactly how the XR-3 will work in dual mode. Perhaps I'm alone on this, but I'm still not sure exactly how this...
One of the problems with use a generator vs using the mechanical energy to drive the wheels is that you will lose about 20 percent of the mechanical energy...
Granted on the losses. So there must be some advantage to a hybrid, otherwise they would not be so good in the current models. It depends on if you want ANY...
How about like this... - Attach the electric motor's potentiometer directly to the diesel's conventional floor pedal accelerator. - When source...
... otherwise they would not be so good in the current models. There are. A parallel hybrid allows you to use a much smaller and more efficient engine that you...
You also need to think about when you use the ice motor you will be shifting throught the gears (VW trans is a four speed). so the throtle will be going up and...
Here is a artical about new capasitor technology to do away with batterys. http://abcnews.go.com/Technology/Story?id=3547157&page=1 found it on homebuiltcars...
... I would suggest that a slightly more complex algorithm would be much better: 1) If motor requirements >75% of genset output AND batteries <75% charged,...
... Yep, I agree. Unfortunately it isn't a one to one relationship. Gear shifts, torque differences, hills, valleys, and I'm sure other factors would vary how...
... And I agree that if you want to go to the expense and effort of an on-board computer system, custom software, sensors, Etc. The 'puter will almost...
A few days ago I was trying to find some information on Ultra-capacitors. I could not find any companies that listed specs or prices. If the claims made be...
You can't just measure the diesel output speed and feed it to the motor controller without also factoring in what gear you're currently in, relative...
How about buildibg it both serial and parallel? - Remove the VW transmission but do NOT put a generator on the diesel engine. - Drive an intermediate drive...
Yes, technically torque is the original output, but for purposes of measuring with a sensor as I described, the final output speed is much easier to measure,...
A quote taken from the source you site (http://peswiki.com/index.php/Directory:FPPMT:FAQ) says: "So really, no PP system is ever over 100% efficient, where the...
One of the emails I got from Mr. Riley sez that some of the delays are caused because he has some patent or other legal protection in the works for his...
First of all, go on with your bad self. If that's your dream I say jump in with both feet. However... Personally, I think you're adding more cost and...
... Thanks for the info Tom. And this reminds me of something I may have mentioned before. I know that you and others in the group have occasionally exchanged ...
You cold have questions sent to the forum leader, lets say they pick the best 5. Then there could be a poll opened for 3 days to see what question the members...
... And I think that would be fine. If needed Tom or I would be happy to set it up. But mostly we tend to hover around one or two issues a week, so I doubt an...
First of all, Ive not absolutely decided to buld it this way, this is a WHAT IF idea to go along with all the Serial vs. Parallel discussion thats been going...
... To further think through this point, I looked at the specs for a number of Ski-doo snowmobiles on their web site. The heaviest "dry weight" was 719 lb...
OK, I'm going to side step the whole CVT issue. I acknowledge that there are CVTs available that can do the job, and since this is a 'What if design' parts...
... Well, I made an assumption - and this may easily be an incorrect assumption - that the weight of the vehicle affected the load that the transmission would...
Im sorry. The other group I participate in is at a much earlier design, testing ideas, and thinking outside of the box phase for the projects they're...
Not a problem, I'm sure. We're just all champin at the bit, doncha know? ... -- Doug Johnson "Communism doesn't work because people like to own stuff." -...
Share the load with two CVTs? Not likely, the two trannies are inherently unstabble in overrun. You could fix this only if you can add in some elastisty and...
