Axial Power Turbine Can Improve Fuel Economy
Axial Power Turbine Can Improve Fuel Economy
Did you know that the EPA07 version of the Detroit Diesel DD15 uses an Axial Power Turbine (APT) in addition to a traditional turbocharger?
Unlike a traditional turbocharger, the APT wheel actually provides extra torque to the engine crankshaft with thermal exhaust energy as it comes out of the conventional turbocharger. The APT uses that thermal energy to drive a gearbox that transfers up to 100 lb/ft of torque at high idle through massive gear reduction.
Understanding this system can help you diagnose an exhaust or turbocharger related symptom. And a properly-functioning APT can improve MPG by as much as 5%!
