LPG Fuel - Maintenance & Troubleshooting discussion in Forkliftaction's forums

Discussion:
LPG Fuel

In my experience, the composition and quality of LPG fuels varies widely throughout the globe. Propane/Butane mixes can vary from 50/50 to 100% propane, yet all is classified as LPG. Also inclusions in the gas can play havoc with sensitive vaporisers. Witht he advent of legislation driving exhaust emissions, surely there should be standards set which are recognised globally, for the mix and purity of LP gases? Anyone else have an opinion they want to share?

Sure the fuel quality can be extremely different.Oil is a bye product during the vaporization and can cause problems.I have the answer that you'r looking for.Drain the regulator on PMI'S.You can get most of it out.It will increase the life of your regulator.Until they regulate fuel quality it's a must.

The mixture of the fuel is not a big deal since trucks are coming out with computer controlled fuel systems. They will compensate for fuel mixture the keep the truck running clean just as a cars compensate for the pecentage of alcohol in the fuel. I think that fuel quality has been blamed over the years for LPG fuel system problems. It was usually worn out parts in the fuel system. I have never taken apart an LP regulator with more than a couple thousand hours on the truck and not dumped the oil out of it. I may be wrong, but I always figured the oil was normal since LP gas is a by product of oil refineing. I just figured there is always going to be some oil left in the fuel.

Good points Wayne. The oil in an undesirable product produced when the liquid LP boils (vaporizes) in the pirmary chamber. Some regulators are designed to allow the engine to ingest some of this product as it is produced, others are not.

Personally I have not had success reducing the oil by regulating the temperature or the flow of coolang in regulator

Take time to do the job right the first time, or you will have to make time to do the job over

Apparently no-one else on the globe feels strongly about this topic - yet the quality of LP fuel can have a direct effect on uptime, productivity, safety and cost of ownership. Forklift machine reputations are also affected as no-one seems to consider the importance of using LP gas with the right calorific value and without gumming impurities which clog up sensitive systems. Finally, when the truck fails to start, very often the operator will try to get it going by fiddling with the gas system. This can have disastrous effects. Would be interested in anyone's comments on the foregoing.
