Well i have a 1995 Civic CX, i get about 45mpg right now. and i want to push at leat 55-60mpg. i drove a prius the other day and i just came up with a idea…let me know if anyone think if it would work…
This is my idea-
Can we have a system to have a electric motor to keep the motor or drive train at a consistance speed when we take our foot of the gas or have a switch to turn it on.
This system would consist of a power supply [battery] a charging system [alternator] and some kind of electric motor to still power the drivetrain when the motor is off.
So basically it will work like this. the alternator will charge the battery or batteries to supply the electric motor with power to turn the engine or wheel once the battery gets low. the gas engine will take over and recharge the battery. this is return cycle.
the electric motor will have to spin as fast as the wheel/drivetrain or the engine rpm.
What do you guys think?
a thought of a 5th wheel in the rear of the car driven by a electric motor that can spin the wheel at a decent 65mph and could run on one or couple of 12v battery for at least 30min before it will take to charge.
I was thinkin a electric golf cart system. in which the charging would be that of a additional alternator that would seperately charge the batteries when it gets low, this is when the gas motor will assist the battery charge.
i know im all over the place but i hope you guys get the idea.
It takes about ~30 hp to keep a car @ speed 60 mph.
So on a 12 volt system and 100% efficiency you would need a ~1865 amp alternator.
Good luck.
If you wanted to use just battery power for 1/2 hour you would need one rated for ~1000 ah. Most cheapy standard batteries are rated at 50 - 75ah. A top of the line Ultima Yellow top is like 140 ah.
The only right way to do it is go more volts and less amps. Which means more batteries and more wieght, cost and complexity.
As far as a motor go with the Perm PMG 132. Nothing less, about $900 and only 15 hp continous, so you would need two. Motor controller is around $500. Deep cycle batteries, $130+ a pop.
I would say go with a 72V system, so 6 batteries. Should almost last the 1/2 hour requirent.
I think the most realistic thing to do for all who are worried about gas prices is to find an extra income stream,rather than waste time coming up with crazy ideas.
eBay,have a garage sale,sell things on craigslist.
Sell all the shit you haven’t used in the past year,chances are you’ll never use it again anyway.It only takes a few $10 items to make a difference.
I’m gonna show all you doubters that infinite mpg can be done and it’s being held back by an oil company conspiracy.
Tomorrow I’m attaching an electric motor to my bicycle, along with a car alternator and battery. I figure once I get it moving the alternator will charge the battery and I should be able to cruise along forever on the electric motor, with the alternator continuously recharging the battery.
design a small op amp circuit that adds some slight gain to the output of the O2 sensor so that the ECU thinks it is richer and pulls some fuel. youd need something like a LM324 and some resistors, capacitors and a regulated voltage for the circuit (7805 or 7812 voltage regulator depending on the op amp power requirements)
lemme see if i can dream up a low gain op amp circuit that can source the current the ecu requires. i doubt the o2 sensor can supply more current than an op amp but ill check.
if i forget, remind me in this thread.
you can use a wideband with a programmable output to fool the ecu into running leaner in closed loop. a buddy of mine does it to a chrysler lebaron and gets 44 on the highway while putting down something like 350 to the wheels.
BTW there is a slight chance of trashing the cat from running too lean but who cares. its a 95. you can take it off and get even better mileage.
*install a more narrow tire to decrease drag.
*slightly over inflate tires to decrease drag.
*run thin engine oil
*run this transmission/gear oil
*increase areo mods like previously mentioned.
*remove power steering (in applicable)
*WEIGHT REDUCTION
^^^^ yeah he could just socket the ecu and run crome or something like that depending on the ecu that he has and the engine. does the cx have the same multipoint manifold setup the ex/si has or does he have that crap dual point setup?
im thinking a simple circuit that you splice in under the drivers seat would be easier.
on www.turbo-mopar.com we’ve found the constants in the ecu that determine the 02 toggling voltage and can change a few values to get the ecu to seek anywhere from 14.8 afr to 18 afr during closed loop though that latter is a bit much and the car will misfire.
SilverGT am I missing something or are you talking about a diy hybrid without things like regenerative braking?
I like the lean-out trick.
The real solution is smaller vehicles. If gas stays where it is then Toyota Yaris sized vehicles will be the norm. You see it in every country where gas is $5+. People just drive small cars.
