22.  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

23.  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

25.  Low permable fuel lines ◦ Imperative customers use the EDI supplied fuel line and fittings  Fuel tank must be made out of metal or a coextruded high- density polyethylene fuel tanks with a continuous ethylene vinyl alcohol barrier layer  Clamps on high pressure hose must be crimped with Oetiker pincers, model 1098i or model 1099i.  A tethered or self-closing gas cap must be used. The fuel cap should incorporate a purge valve that stays seated up to a positive pressure of 24.5 kPa (3.5 psig) and a vacuum pressure of 0.7 kPa (0.1 psig).

26.  Most prevalent issue EDI is fighting on installs  EPA defines that at 85°F ambient and fuel temperature of 127°F the unit will vapor lock  Adding parameters to application review to record relevant data that may expose a vapor lock condition

27.  LPG System  Natural Gas System  CNG System  LP Vapor System

28.  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

35.  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

36. TSG416 WSG1068

37.  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

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

39. WSG1068 TSG416

40.  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

41. Figure 12: Diaphragm Mixer Operation

42.  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

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

44.  Red/Lt Green = 12 volts ◦ Fed from power relay ◦ Initial ignition cycle ◦ Cranking ◦ Running  White/Black = Ground ◦ Controlled by ECU ◦ Cranking ◦ Running

45.  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

46.  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

124.  EG01 – Pre-catalyst O2 sensor voltage; switches between 0-1.0 volts  Closed loop 1 – shows fueling accuracy, 0 = stoichiometric; typically will switch between negative (rich) and positive (lean); +/-1%.  Adaptive 1 – Where the fueling correction is added to the ECU permanent memory. If closed loop 1 goes more than +/- 1% for a certain amount of time. Compensates for manufacturing tolerances in the engine assembly.  EGO2 – Post catalyst sensor voltage; typically ~1 volt OL, 0.8 volts CL  TPS Command – Throttle position ECU is commanding  TPS Position – Actual position of the throttle, should match the command  TPS1 percent – throttle position sensor 1 % open  TPS2 percent – throttle position sensor 2 % open  TPS1 voltage – Voltage value of the throttle position 1  TPS2 voltage – Voltage value of the throttle position 2; TPS1 and TPS2 = 5 volts added together  FPP Command - % of the foot pedal being registered by ECU  FPP Position - % of the actual foot pedal position  FPP1 Voltage – Voltage input of foot pedal, 0.2 to 4.8 volts  FPP2 Voltage - Voltage input of foot pedal 2, 0.2 to 4.8 volts  IVS Voltage – Voltage of the IVS switch from foot pedal

125.  Run Mode – Shows the current engine state; stopped, cranking, running  Power Mode – Key Off, Standby, Active  Fuel Type – Current fuel type the ECU is set too; Gasoline, Propane, Natural Gas  Fuel supply – On or off  Fuel Control Mode – Showing if the system is open loop, closed loop, or closed loop with adaptive learn  Active governor mode – Isochronous or droop, typically all EDI engines are isochronous  Oil pressure state – low, low-ignored, OK  Oil Pressure config. – Ground = Ok, or visa versa  Gov 1 Voltage – Governor 1 input; 12 volts (engage), 0 volts (ground) or 2 volts (open)  Gov 2 Voltage - Governor 2 input; 12 volts (engage), 0 volts (ground) or 2 volts (open)  Oil pressure voltage – Reference voltage; 5 volts = open (low or off), 0 volts = closed (ok)  MAP Voltage – Sensor is 0 volts if open, 0-5 volts when operating  ECT/CHT voltage – Sensor is 5 volts if open, 0 -5 volts when operating  IAT voltage - Sensor is 5 volts if open, 0 -5 volts when operating

126.  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.
