How many people are running propane injection?
"...Fogging or fumigation type dual-fuel systems require little modification to existing engines. The mixture of gaseous-fuel with the intake air charge is introduced into each cylinder of the engine during the intake stroke. During the compression stroke of the piston, the pressure and temperature of the mixture are increased in the conventional manner. Near the end of the compression stroke, a smaller than normal quantity of diesel fuel from the engine's existing diesel fuel injection system is injected into the cylinder. The diesel ignites due to compression and in turn ignites the mixture of gaseous-fuel and intake air, which in turn, accelerates the flame front of the Diesel Fuel, enhancing the combustion process. As will be appreciated, such fumigation systems may be retrofit onto existing diesel engines with little or no modification of the existing engine. Furthermore, engines using such fumigation systems may typically be operated in a dual-fuel mode or in a strictly diesel mode (e.g., when gaseous-fuel is not available). "
