LPG Injection.with conventional injector

[Phil Lamovie]

The short answer is on a hot day it won't open.

The system pressure is always somewhere between 0 & 350 psi.

That's about 10 times higher than a normal petrol system.

Our first systems used 12 ohm injectors with 60 volt S/M
power supplies. That was not a lot of fun and the voltages
were illegal in Oz.

Your valve seats were missing the lead or the replacement
for it. They were also subjected to greater heat stress than
they would expect with petrol. The very high temps in the
combustion can also manufacture some quite corrosive gases.

Material selection is the key for good valve and seat life.

Some taxis get 900,000 kms or about 500,000 miles on a set.
