Cooling System Liquid cooled
Engine mounted coolant pump External radiator Full flow system regulated behind thermostat Located behind water outlet connection Controls and maintains engine temperature Typically opens at 180ºF, fully open around 200ºF Figure 4: 2.3L Belt layout

Water Pump Driven off of the main FEAD belt
Full flow depending on engine speed Regulated by thermostat

Thermostat Typically starts to open between 180-190° F
Fully Open between °F Engines will operate between °F depending on load and ambient temperatures. Located at coolant inlet on 2.3/2.5L (front intake side of engine) Located back of 1.6L at the coolant inlet Sensors will be covered in the electronics section

Cooling Fans EDI offers a suction and pusher fan for every engine model TSG416 and MSG425 use separate belt drive for the fan. Tension is applied by tightening the bearing bracket up. DSG423 and WSG1068 run the fan off of the main FEAD. Tension is supplied by an auto tensioner DSG423 runs off a lone fan pulley WSG1068 runs off of the coolant pump

MSG425 Fan Drive Fan Pulley Main FEAD Belt Extended Crank Pulley
TSG416 Uses Similar Type of Drive

Fuel Systems Two Types of Fuel Systems Utilized Liquid Fuel
Unleaded Gasoline (87 or 89 octane) E10 Gaseous Fuel LP Vapor LPG (HD-5) Natural Gas (1050 btu/ ft 3 ) CNG

Gasoline Fuel System System consists of Fuel block Fuel filter
Fuel pump Fuel Rail Fuel injectors Figure 6: Gas Fuel system

Gasoline Fuel System Fuel block provides fuel temperature and pressure readings to ECU Fuel pump is PWM controlled based on the pressure reading from fuel block Fuel pressure is a preset value in the ECU TSG416: psia DSG423: 74.7 psia MSG425: 58.0 psia WSG1068: psia

Gasoline Fuel System Fuel Pump Typical Voltages
Fuel Pump positive to direct ground ~12 volts DC Power is supplied through 15Amp fuse and fuel pump relay Fuel Pump positive to fuel pump negative ~6-7 volts DC depending on pressure Fuel Block Wiring / Voltages (four wires) Pressure – White/Lt Green – Typically 1.0 to 2.7 volts Temperature – Lt. Green/White – 0 to 5 volts 5 Volt Reference – Brown/White – 5 volts 5 Volt Return – Gray/Red

Fuel Injectors Each injector has a red wire
Supplies 12 volts from relayed power Always on when cranking and running Color wires are ground pulses from ECU This triggers the fuel injectors to spray Timing is preset in the ECU

Fuel Injector Wiring

Gaseous Fuel Systems LPG System Natural Gas System CNG System
LP Vapor System

LPG Fuel System 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

LPG Fuel System Consists of
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 WSG1068s components are the same as the smaller displacement engines except larger in scale

LPG Fuel Schematic WSG1068 LPG Fuel System (shown)
LPG tank pressure = 120 to 180psi Vapor regulator pressure = 11” W.C. LPG from tank; lock off valve located here Air to Mixer Coolant to Vapor regulator LP Vapor to DEPR Air and fuel mixer to engine Vapor Regulator DEPR and Mixer Figure 10: V10 LPG System

LPG System Pict Lock Off Mixer TSG416 Vapor Regulator DEPR

Natural Gas Fuel System
1050 btu/ft^3 is supplied to the engine at 11 inches of water columun Pressure is then 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

Natural Gas Fuel Schematic
WSG1068 NG Fuel System (shown) Natural Gas pressure to DEPR = 11” W.C. Same for whole product line regardless of engine size Air to Mixer LPG from tank; lock off valve located here NG to DEPR Air and fuel mixer to engine DEPR and Mixer

Natural Gas System Pict
Mixer Lock off DEPR MSG425 Engine

CNG and LP Vapor 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 ~ psi before entering supplied regulator on engine

DEPR (Direct electronic pressure regulator)
TSG416 WSG1068

DEPR (Direct Electronic Pressure Regulator)
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 Delta P sensor in the EPR

DEPR Wiring Relayed and Vbat = ~12 volts
Measuring resistance across CAN+ and CAN- should result in 120 ohms

Mixer WSG1068 TSG416

Dry Fuel Mixer 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

Lock Off Valve 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 Valve Positioning
Lock off should be placed as close as possible to vapor regulator (LPG) or DEPR (NG) This will reduce fuel run-out time Lock Off Here on LPG DEPR and Mixer Lock Off Here on NG LPG Vapor Regulator

Lock Off Valve Wiring Red/Lt Green = 12 volts White/Black = Ground
Fed from power relay Initial ignition cycle Cranking Running White/Black = Ground Controlled by ECU

Dry Fuel System Review Vapor Regulator (Vaporizer)
Used on LPG only Fuel from tank connects directly Combined with the EPR on the 2.3L Separate on all other engines (D)EPR (Electronic Pressure Regulator) Precisely controls the fuel into the engine Used for both LPG and NG 11” W.C. to EPR on NG Lock Off valve Prevent fuel from building up in the intake which could cause a backfire Mixer Where the fuel from the EPR is mixed with air Governor After the fuel and air is mixed the governor regulates the mixer into the air intake manifold

Dry Fuel System Installation Notes
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 System 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 Must last useful life of engine

Spark kill – On gasoline only coils can be disabled to locate a possible bad coil; #s listed is firing order Injector kill - On gasoline only fuel injectors can be disabled to locate a possible bad injector; #s listed is firing order DBW test – To test the throttle body by verifying if it goes to commanded position, KOEO, sends the throttle to 0% position. External power – KOEO; Auto (standard ECU control), Relay On (turns power relay on), All On (turns power relay and fuel pump relay on) De-rates/Warnings – Shows if a code is forcing a de-rate, idle, or other condition onto the engine. Snapshot / Flight data base definitions – Shows defaults settings as well as custom definitions that can be added Historic Faults – All of the faults that have occurred on the engine, can only be cleared via the GCP display software Active fault – Only shows faults that are currently active on the engine. Once issue is corrected this fault will disappear and only be listed as historic.

Monitored Drivers Injector-on low-side voltage 0 volts all times Injector-off low-side voltage 12 volts when running 0 volts when unplugged or off Coil Driver Spark dwell [ms] Preset Values in ECU– based on system voltage

Viewing a Fault Two sets of data are recorded
Fault snapshot and Flight data recorder All the variables recorded for each can be seen on the bottom right of the faults page Double click red light next to fault code
