Is there a way to custom fit a catlytic converter from a range rover diesel to a 1969 series 2a diesel to clean up the emissions on my old series. I have asked my local jsf and they drew a blank. If it can be done I would like to know. Thanks
 
I don’t see why not there’s a good range of adapters and fittings available, I would start with looking for the same pipe diameter , I guess it does not have to be Range Rover
On your old diesel it’s done by sight test rather than measuring it that the case with your mot tester

Catalytic converters are for petrol vehicles, it would just clog up with diesel particulates.

Diesel particulate filters are fitted to diesels, it cost landrover multi-million pounds to develop one that worked on the last defenders..
Even that would not work fitted to a 2A, as it's just not designed for that installation.

There are various chemical that can be added to reduce smoke..
I use this one which does make the engine perform better as well..

Would you recommend one? I tried several, and also two stoke oil, not found a really good one yet.
TS oil seems to make my Td5 run slightly smoother, but cant be 100% sure it's not me wanting it to be smoother.
The td5 has a cat fitted but makes little or no difference to smoking, and they get sooty, you can feel quite a difference when you take it off.
 
I've also used two stroke oil which reduced smoke and reduced engine noise by 2 to 3db ( I measured it) however the eco 200 I showed in my post seems to work better.
 
PS the eco 200 says use 1 measure per tank full, at 90 litres my 110 tank is double the size of many cars so I use two measures per tankful..
 
I’d like to experiment with a hydrogen reactor to achieve a cleaner burn. I have heard of good results on more modern diesels (ignoring the fuel consumption claims). It couldn’t hurt to burn off more of the soot before it gets as far as the exhaust.

Other than that a well tuned series engine shouldn’t be producing any more smoke than an ageing transit van.
 
I would not go down this path. A lot of tech that claims to reduce polution also reduces economy so you get a greater volume of CO2. Its an uncomfortable trueth so it gets avoided. For deisels CO2 was the enemy, now its particualtes so its "all change" but don't expect that to last, expect another demon, perhaps the lead substitutes, who knows? Old pre-chamber diesels with low pressure injection are effcient and economical but they produce smoke. Cleaning that up means a major technology change, not a few add ons. The ULEZ have some info, they had vehicle upgrade case studies, but interestingly they seem to have disapeared. They do say that cleaning up the emissions on a deisel van "is likely to cost more than a new van". The case study I saw was a 10 year old camper and the upgrade tech to AdBlue plus fliters cost over £20,000 for the one vehicle. If you see particulates as an issue you need to buy a new Euro 6 vehicle. Its not that I don't see them as an issue, but I manage it by careful driving, limited mileage and driving moslty in the country side where there is no evidence of a particulate impact on health (or most farm machinery would be toast). The particulates - health issue is a city trunk road issue and its moslty buses, trucks, vans and taxis. The impacy of series Land rovers is probaly below what could be measured. Interstingly the research evidence is that one effective meansure is to get rid of traffic lights as it reduces idling. So will that happen, of course not because its nanny state.
 
I was trying to get the smoke down a bit as on start up the vehicle spews out a lot of smoke and it smells. That's why I thought a cat might help. My emissions are legal and they have passed the mot machine but I would like the hc down a bit more. I do use an additive and I have checked and cleaned the injectors regularly. It was just a thought to as I said get the emissions and hc down a bit more. Any ideas if a cat is no good . What would people advise I do. I don't want to change the engine to a tdi 200 or 300 I wish to keep the original Turner rebuild engine in situ. Thanks for the advice so far given its appreciated.

My advice:

1. Get a different vehicle. A classic diesel powered Landy is clearly the wrong vehicle for you.
2. Keep vehicle but don't worry about something that has no real relevance at all.


BTW - diesels over fuel on start up, especially older ones. It SHOULD smoke when you start it. And if it didn't it would probably be difficult or impossible to start.

If you really want to fit a cat then do so. They have no moving parts, so don't need anything to operate. Simply install one in the exhaust, no sensors will be needed. just match the pipe diameter. They work better hot, so will be better suited nearer to the engine if you can find room for it. It may blunt the performance however, but that is only a guess.

Some info on cats:

Most older diesels will give a puff of black smoke on start up, they have automatic excess fuel systems to assist in start up. My 200 gives a good puff every time. [ can get dirty looks in the carpark in town sometimes but that is way it is ] The engine of my Leyland tractor has a button on the pump you press in for cold start so no extra smoke when starting warm.
 
On Bosch injection pump equipped vehicles the use of non Dino diesel can help, sunflower oil mixed with diesel can clean the system.
But for a series 2286, with the Lucas CAV injection pump, this isn't a good idea, as the oil doesn't provide the lubrication the pump needs.

Stick with 2 stroke on a regular basis,and make sure the filters are kept clean, use the better diesel, drive it hard and hot, that's really the best you can do.
 
I found using the Millers diesel additive helped my old 19J-powered 90. Seemed to run smoother, quieter and with less smoke.
