mmm osunds interesting, so the problem is that some unbunrt fuel in the converter can burn in there?
interesting possibility, but givent he temperature at which the cat converter operates (high) I belive this is a NO-NO warning that should have been a maybe.....just like the don't put metals in the microwave warning

titrisol - I just found this from a uk garage website

It says pretty much the same in my car manufacturers manual too.

whoops - wandered off topic a bit here.

I think the photographic paper is excelent for selling on the "black market" now.

Maybe I should sent him a mail with this suggestion, German is no problem.

Best regards,

PS. Vielleicht doch kein gutes Idee

"Another example: ask a young person who has only driven cars with catalysts fitted, and he / she won't be aware of the possibility to start a car (if it has no catalyst) by pushing it to a downslope. "

I remember years ago a woman asking my pal and me if we could give her a push start. We started pushing the car, next thing we hear is this clicking noise and the starter motor trying to turn........... Anyway gave her a quick lesson about bump starting and she was soon on her way.

Talking of bump starts I've learned to check that the driver really knows how to do it before offering to push. So many folks pick first gear and lift the clutch right up, it's not fun head butting the rear of cars.

As for cars with cats, if you are sure it's just your battery that's a little weak or a bad contact on the starter, it's probably OK to bump start it. Cats do not like neat or unburnt petrol/deisel, that's what does the damage and why they say don't dump start em. Also even if it's just the battery, maybe proceed with caution, sometimes strange things start to happen to the digital systems fitted to modern cars when the battery voltage drops and it might not catch.
At least cats are much much cheaper than they used to be ten years. Though why we bother with em beats me, they are pretty much useless devices.

aw, that's not a "sign of times"...people do stupid sh*t like that all the time with film and paper. I worked in a lab about 20 yrs ago and a guy brought in a paper bag with a couple of rolls of film in it and he didn't even wind the film back into the cartridges...he just took the 35mm right out of the camera and stuffed into this brown lunch sack. Had about three rolls of film in there, all ruined--I asked if he knew film was light sensitive and explained how to rewind the camera, and he just shrugged and said he wondered what that little knob was for...

people are stupid, ya know? even at work--had some guy with a dang PHD act as a courier to bring a box of exposed 4x5 neg film over from one studio to the next--on the way he opens the box and pulls out the sheets, so when he gets to our studio, he just hands us the sheets and sez, here's your film...we just laughed our asses off and told him what a knucklehead he was...

then there's this conservator. we get this old studio camera and a bunch of holders from a donor and he sees those flaps on the old wooden film holders had become brittle with age, but he figures the flaps aren't meant to be opened like you'd load a sheet of film. So he glues all the holders shut and then proclaims that he has "fixed" them. Again--we laugh...oh, almost in pain from laughing so hard.... But, then we have to explain to them how sheet film holders and view cameras work...so of course, being a conservator all this can be reversed, so there's no damage, but still....

people are stupid when it comes to film & paper...

A catalytic converter is a piece of metal core which heats up to an extreme temperature in order to help in burning the polutants that may have escaped combustion in the actual combustion chamber. I have bump-started many cars with cats, and this is a theory that someone came up with to sound smart... and with little foundation in reality. The amount of unburnt gas in the cat would have to be pretty high, or over a prolonged period of time to damage it. Bump em if they got the right amnount of pedals - if not, the'y're not really cars, so who cares.

Almost - catalytic converter uses a ceramic substrate for the catalyst, which is a metal, usually platinum, rhodium, and/or palladium. The bulk of the converter is the ceramic, as it takes a small amount of the catalyst to do the job of promoting complete combustion of the engine exhaust.

I've bump-started many cars with catalytic converters and I don't believe there has been any adverse affects from it. I find they end up falling apart from the mechanical vibration before the catalyst gets killed.

Still laughing my butt off...Well, at least the seller isn't out much money.

I'm probably the only one old enough to remember, but you could push start the early powerglide automatics. Just had to get them over 35mph.

What ever happened to chrome bumpers?

I did that in a 1963 Studebaker Avanti (a supercharged one) in about 1983. It took a hell of a lot of pushing to get that fast! - Oh wait, I used a hill, anyway, it worked.

Kent,

"9621 views..."

I actually expected more views.. Thats nothing in comparison with Cardinal Ratzinger´s VW Golf - IIRC it had 5million hits before selling on ebay.de. <g>

"This is obviously making the rounds of the internet."

It does. I saw it at three usenet newsgroups and three other fori.

George Papantoniou · May 14, 2005

I'm not an engineer, but I think that push-starting a car that has a HOT catalyst (was recently running) IS dangerous for the catalyst (the unbubrnt fuel can damage it). If it's cold, (in the morning, before prior use), then it's probably OK. I guess most people have to push start cars that have been out of use for a while, so accidents rarely happen.

Stick shift cars are the real ones, indeed...

This is truly out of topic, and it's my fault... Sorry.

Roman, you're a hell of an intellectual !!! "FORI" ???? Wow !!! Now when I order two "Cappucini" or speak of the Beethoven "Piano Concerti" I like I won't feel so snob, after all...

Actually, the Latin plural of "forum" would be "fora". The neuter nominative ending "um" becomes "a" in the plural. The masculine nominative ending "us" becomes "i".

Actually, my first car didn't have the right amount of pedals, but I still roll started it several times. Seems before about 1965, some automatic transmissions had a "rear pump" which would pressurize the transmission's hydraulics and allow engaging the gears if either the input or output shaft was turning fast enough. I'd put it in low, let it start rolling, build up my biceps and triceps steering without power assist for a few seconds, and when it hit 17 mph, it'd kick into gear and start right up.

You could also tow that one without damage, instead of having to drop the drive line as is recommended for most rear drive automatics; the manual only recommended disconnecting the drive line if you were towing more than 100 miles (to avoid wear on the universal joints).

Bad news was, it got about 10 mpg around town, and cost $12 to fill (when gas was newly arrived at 60 cents a gallon and my monthly disposable income, as a high school student, was about $25).
