One thing I forgot to mention is on my system the waste solvent is just a piggy back system in combination of the normal EFI system? Kind of like a water injection system.
My first test is to bring in the waste solvent system at freeway speed at light load while in lean burn. So EFI Management will be in open loop running on the lean-burn cells in the fuel and timing tables.
I built a manual waste solvent delivery system that uses the HP turbo's compressor housing signal for delivery of hot air (hot air system is copper winding around the inner exhaust pipes, up to 300*F)and waste-solvent. The waste solvent tank is pressurized from the HP turbo and will always run equal too or above the hot air compressor air source. Once the waste-fuel has mixed with the compressor air it will go through a emulsion tube to be atomized even further, then teed off and delivered to the 4 runner direct port intake system. The ports are around 3" from the intake valves.
My original thoughts were to use this system to keep my cat happy and pulse the waste solvent into the engine, acting like a O2 signal cycling.
But then I thought I might as well use the waste solvent for a supplemental fuel that's free to burn and make energy with it.
Anyway enough rambling. lol
