SEPARATELY DETERMINING FIRING DENSITY AND PUMPING DENSITY DURING FIRING DENSITY TRANSITIONS FOR A LEAN-BURN INTERNAL COMBUSTION ENGINE

SEPARATELY DETERMINING FIRING DENSITY AND PUMPING DENSITY DURING FIRING DENSITY TRANSITIONS FOR A LEAN-BURN INTERNAL COMBUSTION ENGINE

A skip fire engine controller and method of control is described wherein during transitions from a first firing density to a second firing density, a firing density and a pumping density are separately set so as to balance the conflicting demands of (a) torque control, (b) Noise, Vibration and Harsh...

Zusammenfassung:A skip fire engine controller and method of control is described wherein during transitions from a first firing density to a second firing density, a firing density and a pumping density are separately set so as to balance the conflicting demands of (a) torque control, (b) Noise, Vibration and Harshness (NVH), (c) air flow through the engine and (d) air-fuel ratio.
