    Abstract: An engine control system for controlling engine operation in activated and deactivated modes in a displacement on demand (DOD) engine includes an impulse charging device that is disposed upstream of an intake port of a cylinder of the DOD engine and that is operable to regulate air flow into the cylinder. A first module initiates impulse charging to regulate air flow into the cylinder when a desired engine torque output nears a first threshold engine torque output during engine operation in the deactivated mode.

    Abstract: A response time compensation system for controlling engine operation in activated and deactivated modes in a displacement on demand engine includes a LOMA system that regulates pressurized fluid flow to switch engine operation between the activated and the deactivated modes and a count module that monitors a cycle count of the LOMA system. A response factor module determines a response factor of the LOMA system based on the cycle count and a compensation module generates a compensated response time of the LOMA system based on the response factor.

    Abstract: A hybrid valve lifter guide formed of metal and nonmetallic material for maintaining the angular position of a reciprocable valve lifter having a circumferential surface with at least one alignment flat. The guide includes a metal guide body having a longitudinal guide wall with at least one guide opening through the wall. The guide opening is adapted to receive a valve lifter. A nonmetallic insert is retained by the body adjacent the guide opening to engage at least one alignment flat of the valve lifter received in the guide opening to substantially maintain the angular position of the valve lifter and dampen angular oscillation of the lifter during engine operation.
