"Researchers estimate the new model could shave almost 1,000 pounds off a car's weight currently taken up by conventional engine systems."
A somewhat different statement, though I still share your skepticism.
- reitzensteinm 15y agoI'm sorry - I was actually reading an article linked somewhere else in this thread, and forgot it wasn't the OP. (http://peswiki.com/index.php/Directory:Wave_Disk_Engine http://peswiki.com/index.php/Directory:Wave_Disk_Engine) Still, even if we're talking about total savings for the car, 1000 pounds is a hell of a lot, and I'm not sure I buy it. For reference, that's 3x the weight of an average V6 (or some light V8s), so it would have to remove a lot and add nothing back. I found an engine weight list here that seems to be legitimate: http://fixrambler.com/engineweightchart.txt http://fixrambler.com/engineweightchart.txt
- checker 15y agoThey mention "a prototype gasoline engine that requires no transmission, crankshaft, pistons, valves, fuel compression, cooling systems or fluids." So maybe add the weight of the engine plus the transmission and extra fluids required for both?
- brudgers 15y agoExtrapolating from the article there's no transmission or cooling system either - that probably doesn't get you to 1000 pounds, but removing the structure which supports those heavy components might get you close. On the other hand, I don't think this would apply to cars with 25 kilowatt engines - a 1958 VW beetle only weighed 1600 pounds [http://www.conceptcarz.com/vehicle/default.aspx?carID=10196&i=2#menu http://www.conceptcarz.com/vehicle/default.aspx?carID=10196&...]
