I've had this idea rolling around in my head and would like some input from others interested in this sort of thing. I have been working on modifications for...
I doubt you will see any change in fuel used. With out opening the exhaust valve you will still have the same pumping loss as when fuel is being burnt. Ed...
Good point Ed. The way I heard it the gains from Chrysler's system, which is more complicated than your proposal, are pretty much confined to the test cycles,...
The following are libel to produce better results at lower cost: Tall, skinney tires and either: make it a 4 cyclinder (throw away 4 pistons) or massive...
You may have a balance problem. It would be interesting to try it though. Shouldn't be that hard to do a quick rig and run it on a back road to see what...
This raises a good point. Your best mileage improvement will come from addon aerodynamic body work. Particularly a tear drop tail and rounded nose. Air...
well for an aerodynamic car traveling along at 60mph belive it or not the air conditioning can actually be using more gas than keeping the car at a steady...
No, I don't believe that in practice. At the red line an automotive AC can take 8 hp to drive it. Unless you have a very odd vehicle, the car is unlikely to be...
Actually, while we're at it, what sort of car uses just 8 hp at the flywheel to cruise at 60 mph? I 'm not saying it can't be done, because it can, but I'm...
Wasn't saying at red line. Was saying at low rpm efficiency cruise. Anyway just got the figures off an engineering site somwhere. ... Bush's family and their...
I've noticed a pretty strong apparent correlation between my pickup truck's fuel economy and the avg. weekly temps in my area. Just thought I'd post to see if...
most times fuel economy goes down in hot dry weather, and up in cool, moist weather. Such as I have noticed anyway. Not to mention running the ac. Paul H. ...
Hey guys, There's just a day left before the early registration deadline for Hybridfest 2006 -- registering by July 12 is the only way to guarantee you get...
Interesting, you hadn't mentioned the ethanol blend before. That would have a huge effect, if they vary the proportion. Cheers Greg ... pickup ... guess ... ...
I know that there are some high output batteries that work best after being warmed using latent heat from exhaust gases, but has anyone ever tried to develop a...
Look up "thermopile". Remember the electricity is generated by a temperature DIFFERENCE. So, one side of the pile goes in the exhaust, and the other side needs...
I found this link about the energy efficiency to produce ethanol: http://www.wonderquest.com/ethanol-assumptions.htm Ed Danzer [Non-text portions of this...
Various idiots (eg UCS) keep saying that it is possible to design a small, lightweight car that will have a satisfactory crash performance in today's traffic...
duh.... bigger and heavier is always going to win in a crash... but ONLY when it hits a smaller and lighter vehicle... it's an arms race... The madness needs...
I think all cars should traditional from a hard shell design to a soft shell design. Basically all cars should have water or compressed gas or hard foam type ...
Greg, Broadly speaking physics will usually win but good design can minimize the damage to human life. Look at the videos on the Horlacher web site ...
... I'm actually quite impresses with how well the smart car's performed in the video. The bouncing around is one way the energy from the crash is dissipated. ...
Unfortunately, I think the bouncing around also translates to the driver's and passengers' brains bouncing around inside their skulls. Greg took the effort to...
... driver's ... That is not at all true. Bouncing up in the air is probably the safest direction to go in. The last accident i was involved in, a driver came...
... direction to go in. Well, sure--but the model I'm assuming is a head-on crash, so we're looking at bouncing backwards on the ground. It's the violent...
so Paul.. your saying heavier is always better? the madness needs to stop somewhere... time to give up on the lie of safety... no vehicle is safe... time to...
Oh, go beat up on Greg. He's the one insisting that SUVs and other behemoths on the road inhibit the adoption of lightweight cars. I happen to agree with him,...
