Liquefied Petroleum Gas (LPG Grade HD-5)
◦ Propane is vaporized and pressure reduced
◦ Pressure is regulated with an Electronic Pressure
Regulator (EPR)
◦ Fuel goes to the mixer where it is mixed with air and
then goes through the throttle and into the intake
air manifold



Dry Fuel Mixer
Electronic Pressure Regulator
Vapor Regulator
Lock off Valve
This is true for all current EDI Ford engines
◦ TSG416 and MSG425 utilize the same components
for their LPG fuel system

Fuels stored at higher pressures
LP Vapor – Propane already in a vapor state;
typically at 300psi
◦ Setup is similar to natural gas; low pressure lock off
valve
◦ Pressure needs to be reduced to 11” W.C. before
reaching the electronic pressure regulator

CNG – Natural stored at ~3000psi.
◦ Similar to LPG setup; high pressure lock off valve
◦ Pressure needs to be reduced to ~100-300psi before
entering supplied regulator on engine


Actuator in the EPR controls the fuel pressure
to the mixer
◦ Actual “delta P” matches the GCP command


Extremely accurate open loop type of fuel
control
After preset amount of time (50 seconds),
engine goes to closed loop control
◦ Uses information from the pre and post cat oxygen
sensors to allow further adjustment to meet
emission regulations
• Relayed and Vbat = ~12 volts
• Measuring resistance across
CAN+ and CAN- should result in
120 ohms



Device by which fuel can be added to passing air
flow
Amount of fuel is related to amount of air
passing through the mixer
This is controlled by the differential pressure
across the diaphragm
More air the engine demands the lower the
pressure in the throat is which relates to the
diaphragm
Diaphragm overcomes the spring force holding it
down to allow more fuel to mix with the air
Figure 12: Diaphragm Mixer Operation



12 volt DC Solenoid driven valve located before
the EPR or vapor regulator
Only open when the engine is starting and
running
When user initiates engine shutdown, the valve
closes
◦ Prevents fuel from getting to the intake system
◦ Engine will continue to run for about 3 seconds to use
up the remaining fuel in the manifold
◦ Prevents an engine backfire from occurring during the
next startup



Referred to as Fuel Run-Out
Low pressure valve used for NG/LP Vapor
Higher pressure valve used for LPG/CNG

Lock off should be placed as close as possible
to vapor regulator (LPG) or DEPR (NG)

Governor
◦ Precisely controls the fuel into the engine
◦ Used for both LPG and NG
◦ 11” W.C. to EPR on NG
◦ Prevent fuel from building up in the intake which could cause a
backfire
◦ Where the fuel from the EPR is mixed with air
◦ After the fuel and air is mixed the governor regulates the mixer
into the air intake manifold

Position of the vapor regulator to mixer/DEPR
is very important
◦ Refer to emission install instructions for:
 Length of LPG hose between vapor regulator and mixer
 Height relative to mixer
◦ If these are not followed this could lead to
premature failure of the vapor regulator
 Could cause oils to build up in vapor regulator and LPG
lines
◦ Keep Distance of Lock off valve to vapor regulator
or DEPR as short as possible

Exhaust must be a closed system
◦ Emission install instructions list
 Distance of pre-cat sensor from exhaust manifold
 Distance of center of catalyst from exhaust manifold
 Length of solid pipe required after post-cat sensor to
avoid false oxygen readings
◦ Ensure oxygen sensors are properly oriented to
prevent water from burning out the sensors
◦ Use 409 stainless steel pipe or equivalent

Allows the user to select the PC’s active serial port and
provides information about communication statistics
Automatic (Default): Permits the software to cycle through
available RS-232 serial communication ports until a
connection is established with a target.
COM1, COM2, etc.: Specifies which communication port to
connect through for a given software session. This setting
is not retained once the software has been exited.

between the PC and ECM once a connection has been
established Statistics include serial baud rate, transmit and
receive loads, and time information.
