Vaporizer requires a normally-closed electrically
controlled fuel lock off valve that is close coupled to the
vaporizer and off when ignition switch is off or when the
engine is not running normally. In operation without a
lock off upstream the vaporizer will flow fuel with the
engine off. The vaporizer is not a fuel shut-off safety
device

The Direct Electronic Pressure Regulator (DEPR) is
the primary fuel control device, used to keep both
performance and emissions control. The DEPR contains
an internal computer, which communicates to the Engine
Control Unit (ECU), via a Communications Area Network
(CAN), high speed connection.
The DEPR precisely controls the fuel flow required to
ensure Stoichiometric (correct air / fuel mixture for
complete burn) fuel delivery to the engine combustion
chambers. The DEPR also contains internally mounted
fuel pressure and temperature sensors, which provide
input across the CAN link, to the ECU, for fuel
calculation. The ECU will process this information and
command changes back across the CAN link, to the
DEPR, to adjust fueling.
The air valve mixer is an air-fuel metering device,
and is completely self-contained. The mixer is an air
valve design, utilizing a relatively constant pressure
drop, to draw fuel into the mixer from cranking, to full
load. The mixer is mounted in the air stream, ahead of
the throttle control device.
