Catalytic Colnverter Question

Thief's love those things. Auto mobile makers are making a ton of money replacing them. Until they are forced to change it they probably won’t.
 
Have you ever touched an exhaust pipe when an engine is at running temperature NR? The underside of vehicles is ideal to maximize airflow across the exhaust, cat converter assembly which is HOT AS...!

Try this

I would have said the same as Fris up there but he beat me to it. Yes, exhaust pipes are on the outside for the airflow but also because well....you really want to get intoxicated by exhaust fumes. You won't notice it at first, its nasty trust me on that one. I had inhaled so much diesel fumes from the lorry, I got a migraine and projectile vomit, I was dizzy and had to stop......had to clean the lorry the next morning. Yeah, not a good idea to have an exhaust on the inside..not unless you've converted it to electric and forgot to take the exhaust system off :lmao::lmao:
 
Surely it could be tucked away somewhere, were it's not so easily accessible.
 
Normal operating temperatures of a converter is 500-800°F, and up to 1200°F when the vehicle is under heavy load. Unless you can design an effective heat sink to continuously bleed off that heat, tucking it away isn't an option.
 
Correct NR. Once combustion engines are a thing of the past, the cat converter thieves will have long since moved on to something else.
 
Combustion engines shouldn't be a thing of the past.......electric pollute before you even get the car approximately 10 - 20 tonnes, then most electric is powered by fossil fuels still, the tyres are the wrong compound, batteries are unrecyclable and cost a mint to replace and if no one has noticed the electricity bills have gone way up to stupid.....I was quoted £1300 per year, that's not including gas supply. so call that £2600 per year when my previous bills were no more than £500 a year. Not sure how they think we on disability can afford that....add charging an EV to that and it will push it way over £3000 per year. Also, for me to buy an EV to suit the family, it would cost in the region of £70,000, I can't even afford the deposit for it, this is the new way of living.....everyone that is on disability, poverty line, homeless, are all suffering under this new WEF and NWO ideology. We have a council that only allows you to drive into certain areas 100 times a year anymore and you have to ask permission from the council! That is communism and if our world is going that way, which it seems it is...millions will be left stranded, hungry and ill in the western world. So screw EVs....even the chinese sales has dropped, which tells you something. I'm sticking to petrol and when that ends I will probably be dead anyway, so it won't matter. lol

Or I will get it converted to LPG but EV battery materials are making the miners sick....
 
I don’t think they can/will eliminate fossil fuel vehicles anytime soon.

Even still you should he able to place a

Catalytic Converter somewhere on a vehicle where it’s not so easily accessible to thieves. It doesn’t take them long at all rip it out, that’s why they do it.

The cat is just after the down pipe from the manifold, the whole vehicle would have to be redesigned. Even then I think you'll be hard pressed to find anyone that thinks having an exhaust inside the vehicle is a good idea. If you make in difficult for thieves to steal it, it would also make it extremely hard to replace it, should it go wrong. The only reason they want them is for the platinum that is in them. It happens over here a lot, where cats get nicked, at least it isn't the whole vehicle that was nicked.
 
No inside is definitely not the way

No its not lol If heat shields aren't the best....I've had 2 come loose on 2 different cars, everytime you go over a hump a little too fart, it rattles the heat shield....do it enough and it will come loose. I've got to fix mine before it disintegrates and the car isn't even that old....well 9 years old August. I've had it 1 year and 1 month...I've had to replace 2 injectors coils, 2 tyres, 1 cv joint, got a track rod end to replace as the rubber is shredded when the cv joint was replaced and the heat shield and it'll be as good as new, if I can be bothered to wash and hoover it lol. I love my petrol engines and they say you're not a real petrol head until you've owned an Alfa Romeo.....and yes I have lol

Well, it was a good car until it got stuck in gear and the gear stick broke when I tried to get it into neutral.....took over 3 weeks to get a new one because it had to come from italy....what a pain in the bottom. I said I might as well take a holiday and pick it up whilst out there...I was joking. So I waited and waited...it turned up, got it fitted and it still wouldn't move. Anyway, with my busy work stuff, I never got a chance to pull it apart but hey ho...the early days when I didn't know too much...now I've worked on not just a selection of car makes and models including the smart car, some vans including iveco, LDV, Ford transits...and of course I've worked on my own cars, so I know a few things more than I did back then. I struggle now doing stuff because of the disabilities so I try to find cheap locals that will do stuff. Unfortunately due to the dire weather we rarely have in the UK lol I can't get out there and do stuff that needs doing.

I would suggest that NR switches to LPG, its much cheaper and will still deliver the power you had before with a bit better mileage I believe. It means having another tank in the car though or go veggie oil/Hemp oil direction

That's a really decent breadth of experience you've had there EMS!

Interestingly (at least to me), in the Colonies where I reside we have huge natural gas reserves which we should be converting to LPG and running all our vehicles. Despite those reserves, LPG is far from mainstream these days with various fuel retailers not selling it and the federal government insisting on maintaining world price parity. This makes zero sense until you add taxes....

Eons ago, I ran a Mitsubishi (Itsabitshiti) on LPG for a few years when I was clocking up a few km's. It ran well and was a good cheap alternative to petrol. Common opinion back then was that there was about a 15% drop in power (not noticeable) and a similar increase in fuel consumption (ie. you get more mileage from petrol than LPG). The question ultimately comes down to the local pricing differential between the two fuels.

It is also worth looking at current thinking about LPG usage possibly eventually burning valves. Years ago it was thought to only be an issue in pre-1980's cars (doubtlessly NR would be driving a 1967 Fastback Mustang). With engines from 1980, running it on petrol once a week was sufficient to lubricate the valves. For the non-mechanically inclined, that involved the simple flick of a switch on the dashboard to change from using LPG to petrol. Super simple.
 
I didn't mean, by any means that I planned to switch to electric. Was merely noting that was probably the only way to solve the catalytic converter problem. Being 75 (in 19 days), I will probably be long dead before we run out of fossil fuels so it's not really a problem for me.

Would if I could, that's for sure. I drive a 9 year old Chevy Impala that I bought right off the show room floor brand new. TBH, it still drives like new - only has less than 38k miles on it (we don't get out much any more). Drove it once to Missouri and across that state after watching the full solar eclipse. Then one trip to western South Dakota to see Mount Rushmore and on to Wyoming to see Devil's Tower. Other than that, we rarely ever leave our home county here in Minnesota. Grocery stores, Mall of America, Hospitals, doctors and dentists are all within 10 miles of home.​
 
Well you know the ole saying “If it ain’t broke….”

If your comfortable in your surroundings and there is no need to leave, then why bother.

LPG is about 99p, diesel £162.99, petrol £1.42....petrol and diesel hit £2 not so long ago.
 
No wonder the Saudis can afford to throw $320M a year at Ronaldo!
 
For those interested in potentially converting their car to run on LPG in the UK, here's a link to an RAC article on the topic from Nov 21.
Code:
https://www.rac.co.uk/drive/advice/emissions/what-is-lpg/
The article states that "Although cars are unlikely to be more fuel-efficient when running on LPG, you could still soon halve your fuel bills. Once the cost of the LPG conversion has been paid off, this could add up to a significant saving – and the more you drive, the more you save."

However, based on current pricing provided by EMS, petrol is currently 43% more expensive per litre than LPG, not double.
LPG is about 99p, diesel £162.99, petrol £1.42....petrol and diesel hit £2 not so long ago.
If pricing is dynamic like it is where I live down under, the difference will change frequently and considerably through a discounting cycle making a meaningful comparison difficult, so bear that in mind. We also need to factor in that LPG drives, say 15% less km per litre than gasoline (ignoring the various types available). Part of this difference is caused by the considerable additional weight added by the steel LPG tank and the LPG with the petrol tank still being in place, carrying very little fuel if you are smart. It only needs to be used occasionally to lubricate valves. Assuming a car uses 8 litres of petrol per 100km, that would cost £1.42 x 8 = £11.36 per 100km. LPG would cost ((£0.99 x 8) x 1.15) = £9.11 per 100km.

If the prices quoted by EMS were static with LPG only saving £ 2.25 per 100km, you would be unlikely to recover the circa £2,000 that I see quoted for a conversion in Manchester unless you drive a taxi! In Australia, LPG is around half the price of petrol although petrol pricing runs through a discounting cycle (currently AUD1.99 to AUD1.75) whereas LPG pricing is fairly static around AUD0.88. Australians all complain about pricing, but thanks to the data provided by EMS, I don't feel so bad about them! The petrol/LPG difference here would ensure payback of installation costs much faster than the current pricing in the UK.

To anyone that read this to the end, congratulations, you can now move on to something more interesting!
 
The petrol stations buy the fuels in and yes prices can vary depending on how much oil OPEC pump out each day....if they reduce the barrelage, fuel prices go up. OPEC are in complete control over oil prices, that's why the US are pushing everywhere for oil, they have their own wells, they have the wells in tar sands, they have the oil rigs in the UK in the North sea, they have pushed for the middle eastern oil....afghanistan, Iraq...I'm surprised they haven't found an excuse to invade Iran lol We don't have that kind of back up.


Remember the fuel shortages in the US in the 70s.....caused by OPEC. That's what happens to other countries that have to rely on them for oil. Oil production should be reduced because its used in plastics, not because its used for fuel
 
As everyone has mentioned... heat, and a whole lot of it.

I remember when the heat shroud came off my brother's truck underneath, and the converter being as hot as it is, got the floor of the bed so hot, it started to melt the carpet.. so we had to rip it out of the truck. Needed to use a bag of ice, which later started to boil.. just to help keep it cool enough to bring the truck home and fix it.

A superb word picture Charvelx04!

The best solution will be to stop installing cat converters and exhausts and user an afterburner arrangement to burn off unwanted gases. Earmuffs may also be required...

I see no point in cats, when you have farmers using red diesel, HGV1,2,3, diesel vans, cargo ships, aeroplanes, open mining vehicles all pollute the atmosphere with more particulates than our cars.
 
No, they get too hot. Do like i did .. go catless. :-)
A visual inspection of the cat is required to pass emissions, just fabricate one with heatshields -- my friend did this.
