Exhaust gas recirculation flow control for reducing emissions with variable displacement internal combustion engines
4 Oct 22
Managing firing fraction transitions of a variable displacement internal combustion engines by (a) avoiding transport delays in an Exhaust Gas Recirculation (EGR) feed by starting movement of an EGR valve position after a decision to transition to a new firing fraction has been made, but prior to the start of the transition and (b) adjusting the EGR valve as needed during the transition so as to maintain an EGR fraction within a predetermined range during the transition.

Utility
Dual rail pressure control for engine noise improvement
4 Oct 22
A method is provided for controlling operation of a fueling system including a fuel pump driven by an engine geartrain and a fuel accumulator supplied fuel by the fuel pump, comprising: determining whether an operating parameter of the engine is less than a threshold value; responding to the operating parameter being less than the threshold value by causing an inlet valve of the fuel pump to operate in a 100 percent fill mode, whereby a pumping chamber in the fuel pump is approximately fully filled for at least one pumping cycle; determining whether a fuel pressure in the fuel accumulator is greater than a desired value while the inlet valve is in the 100 percent fill mode; and responding to the fuel pressure being greater than the desired value by activating an outlet valve of the fuel accumulator to drain fuel in the fuel accumulator to a fuel tank.
