This letter is in reference to the use of the type 14B-1
compressor for hydrogen induction.
After a careful study of this particular problem by our
engineers we feel that Hydrogen induction would
not be feast e wi e use of this compressor. Due to the many
problems which are involved, and the lack of available engineering
man hours, our engineers do not advise converting the present unit
for the use of hydrogen.
As you know, gas would be induced into the second stage
piston, thereby bypassing the first stage cylinder, and the hydrogen
could very easily slip past the 2nd stage piston and enter the
crankcase where it would be drawn into the intake of the first stage
cylinder and then discharged directly to atmosphere. (d u ' ' Q~,Jt 1t,(,U-4? 0
G
Our e g eers~ not mmou "ed the amount of leakage but
they do not feel that hydrogen leaking into the atmosphere of the
test room would be tolerated as a safety measure. There is also
the possibility of hydrogen leaking into the crankcase and forming
a highly combustible gas and causing an explosion.
We trust that this is the information you desire, and if
you would care to discuss it further, please contact this office.
Very truly yours,
