Abstract
An engine control system for use with an internal combustion engine includes a two-step switching device associated with each intake valve. The two-step switching device is switchable between a high-lift position and a low-lift position. A cam phaser is associated with the cam shaft and is operable to change a phase of the cam shaft relative to a crankshaft of the engine. An engine control module is electrically interconnected with the two-step switching device and the cam phaser. The engine control module includes a memory. A computer program is stored in the memory of the engine control module, and is executable by the engine control module to conjunctively control the two-step switching device and the cam phaser dependent at least in part upon a desired engine load.
Claims18
An engine control system for use with an internal combustion engine, said engine having a crankshaft, at least one intake valve and a cam shaft associated with each of said at least one intake valve, said engine control system comprising:
- a pedal module issuing a desired load command;
- a two-step switching device associated with each of said at least one intake valve, said two-step switching device being switchable between a high-lift position and a low-lift position;
- a cam phaser associated with said cam shaft, said cam phaser being operable to change a phase of said cam shaft relative to said crankshaft;
- and
- an engine control module electrically interconnected with said pedal module, said two-step switching device and said cam phaser, said engine control module having a memory;
- and
- a computer program stored in said memory of said engine control module, said computer program being executable by said engine control module to conjunctively control said two-step switching device and said cam phaser dependent at least in part upon said desired load command.
