Bill
Landi Renzo do a gas injection system using an ecu. I am looking into it. I
still need an ecu though

Subject: [Diy_efi] LPG injection


> Glynne,
> I stand to be corrected, but from what I understand there is one major
hurdle which has dogged the concept of LPG injection. And that is the
"Latent Heat of Vaporisation" of the LPG. The reason is that liquid fuels
are injected as microfine droplets, but still a liquid however when you try
to inject LPG it submilates, IE it turns directly from a liquid to a gas. To
do this it absorbs heat from the surounding structure(metal, air, etc) -
large amounts of heat - much more localised cooling than the waste heat into
the area from the combustion chambers - and tends to freeze the injector -
literally freeze it solid (either open or closed!) - thus end of control,
BIG problems! This problem may have been solved, but to my knowledge has not
yet been. This is obviously a much more fundamental issue to resolve before
considering an ECU!
