摘要： A method of valve lift failure detection may include determining first and second intake air pressures in an engine having intake valve lifters that selectively operate intake valves in first and second lift modes. The first intake air pressure may correspond to an intake stroke of a first piston of the engine when the engine is commanded to operate in the first lift mode and the second intake air pressure may correspond to an intake stroke of a second piston of the engine when the engine is commanded to operate in the first lift mode. The method may further include determining a difference between the first and second intake air pressures and diagnosing an intake valve lifter failure when the difference exceeds a predetermined limit.

摘要： Methods and apparatus are provided whereby a single person can test exterior lights of a vehicle. The apparatus comprises a controller coupled to the lights for turning light groups ON and OFF in a predetermined sequence in response to a START TEST signal and vehicle safe-status. Vehicle status sensors are provided for reporting to the controller the status of predetermined vehicle elements whose safe status is a prerequisite for testing the lights. A user actuated switch coupled to the controller provides the START TEST signal. Vehicle safe-status desirably includes transmission in PARK and motor OFF. An internal memory coupled to the controller stores data on prior tests and prompts the user that another test is needed. Prompts are also desirably provided to tell the user what changes need to be made to achieve safe-status for the test. Post test, the vehicle desirably returns to its prior state.

摘要： An engine with cylinder deactivation (Displacement on Demand or DOD™) includes standard (STD) cylinders which are not deactivated and DOD cylinders which can be deactivated by closing their intake and exhaust valves and shutting off their fuel supply. To provide smooth transitions, the STD and DOD cylinders form separate groups each supplied with charge air through one or more separate throttles. When switching to DOD operation, the throttles are oppositely actuated to cut out the DOD cylinders and maintain torque in the active cylinders prior to deactivation of the cylinder valves. When returning to STD operation, the valves are reactivated before oppositely actuating the throttles to enable full cylinder operation. In DOD operation, a small supercharger may be operated to boost torque of the operating STD cylinders and thus increase the DOD operating range.

摘要： A throttling and intake control system transitions between activated and deactivated modes in a displacement on demand engine. The throttling and intake control system includes an intake manifold pressure sensor that generates an intake manifold pressure signal and a controller that calculates a pressure window based on the manifold pressure and an engine speed signal. The controller transitions the engine from the activated mode to the deactivated mode when the measured intake manifold pressure is greater than the maximum limit of the pressure window. The controller transitions the engine from the deactivated mode to the activated mode when the intake manifold pressure is less than the lower limit of the pressure window.
