Definitely the EGR repinning thing was bogus. It sounds like you've already found and looked at the threads that have the diagram and explanation of the Euro/JDM flow shutting valve. As you can see, it isn't a circuit that's there to help you with overheating, it's there to allow ...
With the above-described configuration, outside air is supplied into the collector 92 from the air cleaner, while EGR gas (part of exhaust gas exhausted from the exhaust manifold 71) is supplied into the collector 92 from the exhaust manifold 71 through the EGR valve 96. The outside air fr...
A function block diagram of such a fuel injection control (the control of the drive time of each solenoid valve) may be illustrated as shown in FIG. 1(b). Let's now make a discussion on the ECU 23 from the standpoint of its software. First of all, the ECU 23 is equipped with a ...
FMI 0The difference between the calculated EGR flow and the requested EGR flow is positive. The valve is stuck or moving with delay. FMI 1The difference between the calculated EGR flow and the requested EGR flow is negative. The valve is stuck or moving with delay. EGR cooler clogged. FMI...
So now I suspect the purge valve but what is it? What's it look like? Where is it? All these questions have answers you can find by doing an internet search. I found this diagram showing the purge valve. I compared it under the hood and located the part. ...
The LS4 was equipped with Active Fuel Management (AFM). It’s good for gas mileage, but not for performance. If the valvetrain is in good condition, anAFM disablerplugs into the OBD-II port and will turn it off. When upgrading the camshaft, anAFM delete kitis st...
The EGR device 26 includes an EGR body case 27 (collector), an inlet throttle member 28, a recirculation exhaust gas tube 30, and an EGR valve member 31. The EGR body case 27 mixes part of the exhaust gas discharged from the diesel engine 1 (i.e., EGR gas from the exhaust manifold...
(EGR) conduit opening, on a first conduit end, into the exhaust gas conduit and opening, on a second end, into an engine intake manifold, the EGR conduit having an EGR valve therein responsive to an EGR command to vary a degree of opening of the EGR valve, the method comprising the ...
1. Emission control devices common to EFI and modern Carburetor systems are: EGR Valve 175, Evaporative Emissions Canister 185 and the Catalytic Converter 180. Carburetors are historically simple devices that do not require a variety of sensors to meter the fuel. Carburetor have been replaced by ...
