Hybrid technology increased fuel economy in many ways. Motor produced torque enables engine stop at vehicle stop or runs engine in the optimized modes and Regenerated power by motor in a vehicle deceleration save energy to the RESS. Those are typical way to save fuel in a Hybrid vehicle.
GM developed another way to save energy in a Hybrid vehicle by reducing engine pumping loss while in deceleration fuel cut off. On conventional powertrain systems, the pumping losses cannot be substantially reduced because it would add to response delays when the driver tips in due to the need to pump down the manifold pressure before the fuel can be turned on. However, on hybrid powertrain systems, the electric motor can be used to provide the propulsion that the driver needs until the manifold pressure is pumped down. It is called DFCO Pumping Loss Reduction. We will introduce this new method in this paper and show how much engine pumping loss reduced and how much fuel economy increased with it.
