To all diesel engine owners out there \"Propane Injection\"

What are your thoughts, anyone done it? Propane is easy to buy and safe.

Just google "Propane Diesel" there are hundreds this is from one manufacturer.

"A system that increases horsepower, torque and diesel mileage!

When propane is used properly, it will keep your engine cleaner with less carbon buildup and cleaner oil. Propane is a high-octane fuel and burns slower and longer therefore, propane will help diesel burn more thoroughly, increasing power and torque. With propane your engine should last longer, get better fuel economy and have significantly more power.

By fumigating the intake air with propane, there are dramatic increases in power, torque and diesel mileage. By using a dual stage regulator and drawing vapor from the tank, this system creates one of the most user friendly, maintenance free systems available. With this system, exhaust temperatures are only slightly increased and in many cases decreased. This converts to one of the safest horsepower increases on the market. The vapors are drawn from the top of the tank so there is no liquid to vapor converts to worry about, which makes one less problem to have. This system can be adapted on any turbocharged diesel and is easily transferred from vehicle to vehicle."

This kit is $700USD, the propane is introduced into the turbo via a simple regulator. All you need next is a Propane bottle and Hey Presto!

If it was that good wouldn't Volvo etc already do this??

There will be a catch of some discription, extra stress on the engine, reliability issues or something else /forums/images/graemlins/frown.gif
 
Re: To all diesel engine owners out there \"Propane Injection\"

Yes it will add more stress of course. But when you think the old Volvo AD41 which started off as a fairly unstressed 200HP engine and over the years Volvo ended up getting more and more horsepower out of it by adding bolt on superchargers, intercoolers etc eventually 265HP (Kad 300) out of the same old basic block. I think reasonable power gains are safe? Even the D6 is gradually becoming a more and more stressed member what are they up to now 350, look at the D4?
 
Re: To all diesel engine owners out there \"Propane Injection\"

Perhaps there is some law about Propane as a fuel? Propane is normally for heating, cooking etc so will have a different VAT and duty rate so perhaps it can't be used as a fuel? That is my guess why Volvo and other manufacturers don't use it.
 
Re: To all diesel engine owners out there \"Propane Injection\"

Isn't Propane just LPG? If so it's already available as a fuel for petrol engined boats and cars
 
Re: To all diesel engine owners out there \"Propane Injection\"

Errrm, yes. Those higher end blocks might be the same bottom end (boring bit) but different cylinder heads (interesting bit).

Feel free to try it out. Picking the pieces of piston and con-rod out of the bilge will keep Col out of mischief for a bit /forums/images/graemlins/smile.gif

Anyway, why mess around with propane when you can go NITRO
 
Re: To all diesel engine owners out there \"Propane Injection\"

Propane gets added to the diesel to make the diesel burn more efficiently. LPG engines run entirely on LPG or Petrol, ok they start on petrol and change over to LPG but do not run on a cocktail of the two.

Maybe because "Boat Pull" isn't recognised anywhere yet, but Truck Pull is?

Nitro / Propane more designed for THIS. or THIS.

Sometimes resulting in THIS /forums/images/graemlins/shocked.gif

I've got D6 435's in the P42...

Bonkers technology.

NOT approved by any engine manufacturer.

I purchased my engine dyno from a company who had been doing research into 'Propane fumigation of Diesel Engines' for the Energy Savings Trust.

There were some concerns about exhaust high gas temperatures which would lead to premature exhaust valve failure.

However the research was instantly halted following a series of engine 'run aways' on the dyno. If the equipment continues to fumigate when the throttle is closed engine runs on. All vehicle trials were halted on safety grounds when truck drivers also experienced similar problems.

Nowhere near as dire as a 44 tonne truck, however shutting the throttle whilst manoeuvring in a crowded marina and suddenly getting the engine going to WOT on a sniff of LPG. Just the opposite of 'Quick boost and then back off'
 
Re: To all diesel engine owners out there \"Propane Injection\"

OMG. Don't show that to HLB. He'll have one fitted to MF in no time /forums/images/graemlins/wink.gif
 
Re: To all diesel engine owners out there \"Propane Injection\"

The guy who fitted the LPG conversion to my Jeep Grand also does LPG conversions for Diesels.

There is a power / economy increase of approx 15-25% when administered properly - cost is around £1500.

Why don't manufacturers do it??? Why doesn't every new petrol car come ready to run on LPG? Why, when you ask a manufacturer about converting to LPG they cover their ears and wail about invalidated warranties and how horrible it all is...

Fundamentally LPG is a good fuel but there is way too much prejudice about it - in Australia all Taxis run on it, in Italy a huge number of cars use it - however it's still very much an "underground" fuel in this country which is weird bearing in mind our fuel prices!

As I understand it, it burns better, so when you add it to the diesel engine it helps the diesel to burn much better improving the overall efficiency of the engine.

I know it's tempting to poo poo it, but this does actually work well - and currently LPG is around 50p per litre - although for a large boat it's useless since Calor took away the marine support.

For a van however - especially a lower powered version of an engine that you know will take more power easily - it could work very well. You could fill up the LPG at any Autogas station, I can't see how you'd fill up a boat - you certainly couldn't use the small portable propane bottles.
 
Re: To all diesel engine owners out there \"Propane Injection\"

There is another method of dual fuel out now, compressed natural gas which is burnt with normal diesel. Electronic signals to the injectors is piggy backed to release cng directly behind the inlet valves. diesel to initiate the combustion ,cng for the main power
