Electric car thread

SOL is also the sun. Car motors back in the 50's did pretty short miles before needing an engine rebuild and you were always doing "something" to the car.  Nev

The fossil fuel Farm Boy is going to get a shock soon. "Twiggy" Forrest has just purchased 360 huge battery-powered dump trucks, 55 battery-powered giant excavators and 60 new battery electric bulldozers from Liebherr, with the intention of being fossil-fuel free on his iron ore mines by 2030.

 

That's really putting your money where your mouth is. Farm Boy is going to end up whingeing (they're good at that) about how he can't compete with his fossil-fuel tractors, when farmers with battery-powered tractors are running rings around him with lower operating costs.

Not true.

I drive my " tiptronic " automatic Pajero like a manual ! .

Why ?, short occasional runs leaves the battery a little less charged 

each time , changing to lower-gear gives a little more charge .

so smarty uses the gears to slow-down , to navigate roundabouts . & 

Roll to the stop-light , without using those nice new brake ' shoes ' & 

Disk-pads I replaced this year .

 Alternators should charge at low revs. That's why they are superior to DC Generators with commutators.  Nev

[spacesailor]

They do. But at higher revs you get heaps more amps .

I haven't had a long drive for along time .

It means. More oil changes  ,  because the oil ' on the dipstick ' is getting more each month .

Not less,  ( water adding to the sump reach shopping trip ) .

At higher revs the output is still regulated and will not be altered by higher revs unless it's a permanent magnet thing which would be very unusual on such vehicles. 1500 engine revs would get you as much as higher revs will. The rotor is an ELECTRO   Magnet and varies when the current to it  does. Nev

[spacesailor]

 BUt at 3,000 revs it won't get the high 'amps' . Or the 12 minutes trip doesn't charge much either. 

I'm not rural,  but relegated to that mandatory  50 k maximum speed .

PLUS those five red traffic-light's .

Oh , I do miss that ' open road " to anywhere.

Your Alternator should charge at idle speed. Are you running with your Lights on and does your dash include a Voltmeter?. Most of my vehicles never see 3,000 RPM.  How quickly does the engine start?   Nev

[spacesailor]

I must check those ' revs ' , as they were only a guesstimate .

But the car will stay " all alone " ,  locked up , in the garage , the battery looses a little bit daily by it's ' alarm system ' and all the electrical gadgets.  

It's one reason to go ' electric ' .no warming up , & getting a sump half-full of water .

I didn't think that I had ' overfilled ' the sump after the last oilchange !, 

But the oil level is above the full mark now .

I would suggest that water in the sump indicates a serious problem, such as a blown head gasket or cracked engine block.

 

[facthunter]

A gallon of petrol Makes more than a gallon of water. I've seen evidence of water in  Aircooled Aero engine Oil. (Cloudy). Nev

Write the chemical equation and do the atomic weights if you don't believe me. Nev

I don't doubt that, you can see moisture from exhaust pipes on cold mornings, and even feel it if you put your hand near the exhaust. Water in the oil, however, is not normal and is usually a sign of serious problems.  

[spacesailor]

All IC motors  create h2o ! .

When cold the piston will not have expanded to seal the bore .

That's the big problem of short trips . Then that steam vapour condenses onto the still cold metal

And also onto the cold oil . Then that condensate sinks to the bottom & stays out of the heat  .

Awaiting the return trip to add a little  more. 

my oil is nice & clear , so  no worries .

spacesailor

 

PS. :  A smaller motor , than my 4lt V6 ,

Would help to warm-up as less cold metal ' mass. ' to heat .

Sounds like you need an EV Spacey. 

No sump, rings, pistons, cylinders, oil or petrol to worry about.

[spacesailor]

Or, an " air-cooled " two-stroke. 

I once parked behinda VW beatle  ( air-cooled )at a ' ski resort ' and was roundly told-off, " your block will freeze & crack at this hight,  with it's very low temperatures " .

So I had to drive a mile back down the mountain to the ( common man's ) carport .

No problems with ' water in the sump ' or ' Freeze cracked block ' .

A little diversions.

 

I was at Bunnings the other day and saw a Ryobi ride-on battery powered lawn mower. It was a big one that would suit commercial use. The price tag was big, too ... $9990.
