Sorry, thought I better add more information.
It was on a truck with a standard fuel injection pump, not common rail.
Truck started and ran on diesel when idling.
As more throttle was applied, LPG was injected into the system to supply more power, and the diesel injection was turned back from the usual setting.
Concept was that LPG assisted in the combustion of the diesel, and suplemented the diesel with a cheaper fuel.
All
well and good, great idea, but in execution, he had starting problems, and running problems, getting the diesel to LPG ratio correct.
After 12 months, and the number of times he had been back to the installer for fine tuning, and the income lost with returns, it worked out to be cheaper to run on straight diesel.
Now, with a computer controlled common rail system, maybe it is easier to get the deisel control more accurate, and match it to the LPG? Leave that oen for the diesel experts to confirm.
