The wastegate on the DualBoost VGT is vacuum controlled through a solenoid that is controlled by the PCM. The wastegate is only used on the…
The 6.7L VGT actuator uses engine oil pressure on a piston to move the vanes on the exhaust turbine. The VGT actuator is commanded by…
During engine operation at high engine speeds and load, there is a great deal of energy available in the exhaust. Excessive boost under high speed,…
During engine operation at moderate engine speeds and load, the vanes are commanded partially open. The vanes are set to this intermediate position to supply…
When the VGT is closed it maximizes the use of the energy that is available at low speeds. Closing the VGT accelerates exhaust gas flow…
The DualBoost VGT has two intake compressors and one exhaust turbine on a common shaft.
Turbocharger control is based off an air system model that produces a desired intake pressure to meet the power requirements requested by the operator.. The…
Some of the features of the ceramic glow plugs that are used on the 6.7L Power Stroke® diesel are: • End of compression temperature is…
The glow plugs are mounted in the cylinder heads and are accessible through the valve cover. The GPCM supplies the required current to each glow…
