I have a CAT 3306 DI Turbo generator set running on a blend of Waste Motor oil and diesel. I have blended up to 50% ratio and its fine for about the first 5 hours at 50% to 75% load. But then it starts smoking. By hour 15 I need too shut down and clean injectors. Which i do every day.
I have an Alpha laval MAB 103 centrifuge that I spent $12k on that runs 24/7 cleaning the waste oil prior to blending. I batch 200 gallons a day (100 gallons waste oil / 100 gallons diesel). The main fuel tank has a 10 micron bulk filter with water separator on the fill line. The engine supply line has a DAHL / 200 2 Micron filter water separator and the secondary filter is a standard CAT 2 Micron filter. I think I am pretty clean going in.
I have an inline water jacket heat exchanger that bumps the injection temp to about 135 F. Im not able to get more temp out of it and i dont know why. Maybe its too small but I have recently installed an electrical heater element from a hot water heater with a thermostat to assure me at least 150F or maybe higher injection temps. That hasnt been tested yet.
I also collect 100 gallons of cooking oil from KFC a week and am wondering if the animal fat contained in that oil that settles in the bottom are a problem. I can heat it till its clear so im thinking it should be ok just run it through..
My generator over heated last week and I found the rear manifold to be much hotter than the forward manifold. In the dark after shut down I saw the turbo was red and the rear manifold red.The forward manifold was dark and cooler. This was after a two minute cool down which was shocking.
I have a Fluke infer red heat gun but I didnt take measurements before the shut down on the manifold. Usually it runs about 600-800F. The turbo runs about 1000 F.
My fuel consumption on 100% #2 diesel is about 9 gallons per hour. When I run 50% motor oil the over all volume drops to about 6 gallons per hour. I am assuming because the waste motor oil contains more energy/power per gallon.
My problem with the over heating condition is a major issue and i havent gotten to it yet because i hurt my back shortly after the shut down. Im hoping its injector related. Advice on that would be appreciated. I eliminated the cooling system. Radiator, oil cooler and thermostat are 100% ok. Oil level is also ok. Im thinking valves or injectors.. Praying injectors. I have an injector test bench and can take injectors apart and clean. For those of you that are reading this with no experience and think you can do this ... dont. I am not a super mechanic but i am well equipped and have done this before. If you take an injector apart and dont know what your doing, be prepared to toss it in the trash when your done looking at it. You need a pressure test bench and proper facility to handle this. The internet is full of people talking about stuff. Most of it is crap. No different than a Bar room discussion.So please be careful when dealing with expensive components or engines with only things you read off the net. Im seeking advice here because I kind of know what im doing but want to hear from others how to do it better. I can sort out the bad advice because I know enough to do so. I hope that saves someone a lot of grief. I know how many people read these forums in hopes to find the magic solution to cheap fuel.
I want to run the motor oil. I have lots of it and have been doing this for 12 months. But daily cleaning of the injectors due to smoking is getting taxing on my time. Can anyone advise?
I dont care if i destroy an engine every 12 months. The money we save on fuel is worth it. But I cant keep baby sitting this thing daily and grow my company. I need some help.
I have another customer ready to go online with 4 times this power. But I cant do it until I get this one straightened out where i dont have to clean injectors every day.
Im also looking at burning coconut oil. I can get 30k gallons a month at a landed cost of about $3.00 a gallon. I live on a remote island in the south pacific called American Samoa. I am originally from PA. If anyone wants to get serious about this and help get me sorted out, I can help you get all the coconut oil you can handle delivered to your door step.
