  • Cleaning Injector Restricted Pump and Injectors from chicken fat buildup

    Hi All,

    I have been running chicken fat through a heat exchanger in the Triton 4d56 motor1991, as well as my Shibaura Stationary Generator Motor and it has been working superbly, however the other day I did something very stupid when I went to a mates place thinking to be there 10 min and was there 3 hours in between time the outside temperature dropped with oil still in the injector system needless to say the 100k trip home was very very slow and painful not to mention the difficulties of even getting the motor started. Top speed 70k and more smoke and smoke pillowing out of the exhause even though I had changed back to Diesel. Then proceeded to try and use injector cleaner nothing worked Had no hair dryer so couldn't blow dry the injector pump to hopefully melt the oil which was clogging the injector pump. Had come to the point where I was looking to replace the injector pump itself. Non available some close but not the exact model number. Needless to say nearly bald by this time, I had been following the exploits of Craig with his Suburban and was impressed with the faith he displayed in the CEM products. I contacted Craig and asked him about the products and was further fortified by his response, so I then rang the company itself. They were very very helpful and took the time to answer any questions I threw at them and they don't call me "Have a Chat" for nothing.

    Here was my problem I had determined that it was the injector pump that was partially blocked and whiles sometime I would get to 2400rpm as soon as it went under Load it would drop back to between 1900 and 2000 rpm a top speed of 70k and any load at all slowed it down even further. As some of you know I am not flush with money so the choice was either another injector pump ( not quite the same Model) and many hours work trying to fit it with no experience of doing this or the fuel treatments I didn't have funds for both.

    If this worked as I hoped it would even if it took a couple of tank fulls to work at least the problem was solved and I could then use it on my old diesels to help improve them. I am a health Surveyor by profession which means nothing in the scheme of things. But one thing they did impress on us over 2 years of study and it was this "Prevenitive Medicine is cheaper and more effective than curative Medicine ".
    So we brought the CEM products. So at this point I am going to either tell you it was a waste of $220 or not.

    I am extremely pleased to say that within 90k the motor was performing better that when we bought the vehicle 4000 k earlier. Where earlier it was a struggle to reach 100k, now I was having to take my foot of the accelerator as I had reached 110k no longer was my foot sore from being at full pedal coming home. There seemed to be much more power and the reaction time to reach 2500 rev's was much quicker and the vehicle much more responsive and powerful the type of response I had expected but not recieved previously.

    Before when I accelerated in 1st and 2nd there was a plume of some when I had a load on and it had a blue tinge now the plume is smaller and it is more grayish. I might have to go to a heaver grade of Oil and stabliser to overcome this or it could be just the deposits being blown out.

    All I can say at this point is that the Injector cleaner and decarboniser are working wonderfully. I will further try it in my tired old Stationary motor we are using for the generator and will keep you informed.

    Whilest the problem was fully self inflected I am very pleased with what has transpired with the additives and it may turn out to be a blessing in disguise as preventing motor failure and increasing usable life is better than rebuilding them before there time.

    Hi,
    Please tell us more about the "CEM product" you used? Especially interested to know what's in it. $220 is fairly steep but better than new IP I suppose you could argue.

      Hi Third,
      CEM or Cost Effective Maintence.
      Cost Effective Maintenance
      That is there web address.

      I used 2 ptoducts of the 3 I bought,
      FTC Decarbonizer

      Burn off carbon from combustion & exhaust spaces. De-cokes, deglazes, genuine fuel savings. Saves rebuilds.

      Cleanpower Fuel Treatment

      Cleans pumps & injectors, cuts smoke, rough idle, restores fuel economy.

      Flushing Oil Concentrate

      Restores pristine cleanliness to oil wetted parts of engines, frees stuck piston rings, de-sludges. Saves rebuilds.

      While the cost may seem high they are concentrates and before I put any of theses in I had just put in $15 of an other injector cleaner which did extremely little if anything something I had been using for years. So in reality which is cheaper $15 for something that does nothing or $220 for something which saved me replacing the injuctor pump if when I had a hair dryer to heat the injectors which at best may have restored the power I had not what I now have. There is still another 10 treatments left as well as well as the Oil Flush which another member gained an extra 3 liters of oil and sludge when he used it and what I will be trying on my next oil change. As i have several old machines I though that if it worked then it would be worth it

      So yes some things may seem expensive and to tell the truth I would not have invested in if I didn't develop the problem.

      I can only say what happened with me.

      Gene
      P.S. I have in no way any connection with the company or its employees and only first heard of it on this forum from a member I had not previously met but whom I have conversed.

      If there are any other members who use these products perhaps they make like to tell of there experiences GOOD or BAD in case I am an exception to the rule. However on the current information I will be continuing the use of these products because of there effectiveness currently experienced.

        Thanks for link and info on that.

        After studying the product I find it's naptha based, as most injector cleaners are. Also has various oxygenates which are probably alcohols.

        Naptha is otherwise known as white spirit, lighter fluid, coleman, stoddard etc.

        I reason that the trick here is to get ingredients that have a high boiling point and I note that naptha boils between 30'C and 200'C. Heavy naptha has the highest boiling point. What is interesting is that stoddard fluids are often an injector cleaner ingredient and a quick search shows a boiling point of 140'C for one example of a stoddard product.

        Naphtha normally refers to a number of different flammable liquid mixtures of hydrocarbons, i.e. a distillation product from petroleum or coal tar boiling in a certain range and containing certain hydrocarbons. It is a broad term covering the lightest and most volatile fraction of the liquid hydrocarbons in petroleum. Naphtha is a colorless to reddish-brown volatile aromatic liquid, very similar to gasoline.
        Naphtha is defined as the fraction of hydrocarbons in petroleum boiling between 30 °C and 200 °C. It consists of a complex mixture of hydrocarbon molecules generally having between 5 and 12 carbon atoms. It typically constitutes 15–30% of crude oil, by weight. Light naphtha is the fraction boiling between 30 °C and 90 °C and consists of molecules with 5–6 carbon atoms. Heavy naphtha boils between 90 °C and 200 °C and consists of molecules with 6–12 carbons.

        Could this be a way to get a cleaner that works at a price that doesn't cost an arm and a leg?

          mate,

          You lost me after , "after studing".that explains the burning in the chamber must also have something that acts as a detergent to clean the lines and Injecter pump as well

            Tbird,

            I am the member that Gene was referriing to.

            I have been using their products for about 4 years now - initially in my Petrol Ford Explorer, then my first Diesel a Toyota Surf. And now in my Holden Suburban.

            I found in the 4 cylinder Surf that it did a fantastic job - i have just put the FOC through the Suburban as well as the Cleanpower and AntiWear products.

            I have had a number of people say how much better the motor sounds since they first heard the car (i have also started using BIO recently so am sure this has helped as well)

            I am very happy with the products and their cost effectiveness.

              That's great. I also lost focus at after researching .

              anyway , looks like a great product and I think my wifes car might need some of the petrol stuff.

              It's just down the road from our warehouse at Sumner Park

              Might have to get some. Thanks for that post.

                Note: Naptha is also the active ingredient in gasoline (petrol) and paint thinner. As a blender I have been experimenting with solvents to thin WVO for 5 years. My solvent of choice is gasoline (petrol), because in the USA it is the cheapest, and most accessible solvent available. However, I have also found other solvents work as well, such as: acetone, pure gum turpentine, xylene, toluene, MEK and lacquer thinner. I have also tried dissolving animal fat with these same solvents. I found they work much better with vegetable oils, but they will dissolve and/or mobilize small amounts of animal fat. So, you could try adding any one of the above solvents into your fuel to dissolve the accumulated fat in your injector pump.

                  Re: Cleaning Injector Restricted Pump and Injectors from chicken fat buildup

                  I've experimented with all but the gum turps as well. Here ulp has historically been the cheapest also.
                  I suppose my point is... why pay big money for injector cleaner when you can buy the product ingredients for a fraction of the price. A quick local search showed white spirit at $9 a litre. Methanol is $3 a litre, Isopropyl Alcohol is $7

                  According to CEM website 250mls of Inj cleaner is $44. Thats a rate of $176 a litre. The 5L rate works out at $44 a litre.

                  My van has power loss when ulp or solvents are added to the fuel. The more added, the more power loss. However, power is fine first thing after starting in the morning and until temp reaches about 40'C in the injector lines. Power will drop away as temps rise, more so in extreme hotter weather and bubbles will appear in the return line when above 70'C - 80'C range. Restarting when hot is noticeably more difficult too, but nothing that some extra cranking won't fix.
                  All things aren't created equal and in my vans' case the fuel tank doesn't have the benefit of cooling from open breeze. In fact I have logged the temps rising in the tank from simply parked in the hot sun to above 30'C

                  The high boiling point Heavy Virgin Naphtha (HVN) appears to have the advantage that it could be stable in the fuel lines and especially in the hot injector lines.
                  Shortly, I'm going to mix a blend of naphtha and methanol for testing out.

                  On a foot note, about 2 weeks ago I added a cocktail of xylene, methanol, acetone, toluene and white spirits. Already there was a small amount of ulp in the fuel. I thought this would really clean up the IP & strainers. The effect was unexpected. In the end, I had to remove the strainers to clear them. Now I'm wondering if my cocktail loosened and flushed the floaties into the strainers?
                  I had a thought of constructing a remote strainer thats several times the capacity and most importantly accessible. Anyone who owns a Hiace knows how inaccessible the IP strainer is on them! The plan would be to remove the existing strainer in this instance.

                    I agree, so I just stick to gasoline (petrol).

                    On your strainer idea, I added two traps in my fuel line, which have helped to trap particles, water, sludge, etc from my fuel. Here is a pic

                      Re: Cleaning Injector Restricted Pump and Injectors from chicken fat buildup

                      That's a good idea there Jeffrey. I can see that gravity will pull the particles down and settle them before periodic draining.

                      My idea was on similar lines. I want a gauze, several inches in diameter and of same mesh as the IP strainer. This would be housed so that the fuel flowed vertically. Any loose particles caught would be allowed to settle downward to a trap with a drain tap. This could possibly allow longer periods without intrusive maintenance. Sadly I reason that no matter how many strainers and filters the vege gets put through, still the dreaded grey stuff can fall out and cause problems. So, I'm still planning the homebrew injector cleaner. With enough effort and trying things, I may find something good.... who knows?
                      As a thought on this idea, I'm wondering if successful, would it be better to add it every so often as a birthday to the IP/system or add as part & parcel of the fuel itself, like the fuel companies do?

                        Yes, I agree tbi9rd650, my trap could be improved by adding something inside of it like gauze. Maybe fine steel wool would work. I have been using y-traps made by Banjo here in the USA as a pre-filter to my fuel processing system. They use both gravity and a screen. I use two 1.5" y-traps in series, one with a 40 mesh screen, then one with an 80 mesh screen. I am planning on purchasing a 1/2" y-trap with a 125-mesh screen in it in front of my 12-micron fuel line filter. But, I will keep the above traps in place, because the more traps the better.

                          Very good info on the stoddart fuel. I was advised about 3 years ago by a forum member whos brother was a chemical engineer. He said use 2ml per litre of veg oil to keep system clean, Have always used it! Just blind faith but I have some tech talk behind me now. Thanks.

                            Jeffrey, that's a cool looking piece of kit... I like it.
                            I had wondered if there was any adaptable strainers in the water/plumbing industry.

                            PeterAC. the stoddard is present in 6 of the 8 cleaners in the msds info I looked at. Of the the 7th, it had a secret formula so could still have contained some. If I recall, stoddard naptha is an extract of coal. I recall using a coal based degreaser/ carbon remover some years ago and its' cleaning power was impressive. Any stories to share re stoddard as a detergent additive?

                              Is that a metric ruler there I see??? In the States??

                              What gives? do you guys openly use the metric system too or am I missing something here?
