Listeroid Engines / Re: listeroid working on BI-FUEL, diesel/LPG mixture.

hi,

the LPG is regulated as follow: you operate a solenoid valve throw a current relay (using a CT to sense the load), this solenoid permit the flow of the gas, calibrated by the respective presure regulator to the air inlet stream. the idea is to set the LPG inlet just when the machine is in the maximum compsumition point, replacing the diesel's energy by LPG.

the engine works quieter, drastically lower the combustion detonations. But this only have sense when the LPG is 50% cheaper than diesel. :-\

Hi,

The point using LPG is: the LPG not only improve the combustion quality (5 - 10% of diesel is exausted unburned in a normally aspirated engine), and when you use this mixture, you are replacing the diesel BTU's by a cheaper (at least in my country: Dominican Republic) LPG BTU's.

another side advantage is: when you burn less diesel, you are adding less sulphur to your lube oil, preserving more the TBN and extending the oil life.

the objetives are:
1) improve the combustion eficiency of the diesel.
2) replace the 40 to 60 % of the diesel enery by a cheaper and cleaner fuel LPG.
3) extend the oil change intervals.

vapor of course, throw the air inlet stream. the LPG is proportional to the engine load, measured by the generator power output.

Hi,

I am new in this forum. I have a large experience working standard diesel engines with a diesel - LPG mixture (40% diesel - 60% propane). I can report about  25 to 35% in the fuel bill, producing the same energy (KW/H) compared with plain diesel fuel. It works in any direct injection engine, I have this system installed on two cummins 6CT, one cummins 6BT and one yanmar TF-140. My next proyect is to install a new prototype system on a LOVSON 8/1.
