摘要： A method may include commanding operation of an engine in a first lift mode. The engine may include a valve lifter system that selectively operates a valve member in the first lift mode and a second lift mode through engagement with a camshaft. A first duty cycle of a cam phaser oil control valve (OCV) may be determined to maintain a first camshaft position corresponding to the first lift mode. The camshaft position may be maintained by a cam phaser that is coupled to the camshaft and in communication with the cam phaser OCV. Engine operation may be commanded to the second lift mode and a second duty cycle of the cam phaser OCV may be determined to maintain a second camshaft position corresponding to the second lift mode. A valve lifter system failure may be diagnosed based on a difference between the first and second duty cycles.

摘要： An engine control system includes a cam phaser that introduces a cam phase angle θ between a camshaft intake lobe and an associated crankshaft. An engine control module communicates with the cam phaser to introduce the cam phase angle θ while an engine is being started. The cam phase angle θ is selected such that the camshaft intake lobe opens an intake valve during at least a portion of a compression stroke of a cylinder that is associated with the camshaft intake lobe.

摘要： A camshaft phasor control system for an engine includes a camshaft position sensor that generates a current camshaft position signal based on position of a camshaft. A first comparator generates a camshaft position signal based on the current camshaft position signal and a crankshaft position. The second comparator generates an error signal based on the relative camshaft position signal and a commanded camshaft position signal. A control module determines a current control hold duty cycle (CHDC) for a camshaft phasor based on an engine state parameter. The control module also generates a correction signal based on the error signal, adjusts the current CHDC based on the correction signal to generate a commanded CHDC signal, and generates another CHDC based on the commanded CHDC signal.

摘要： A method of operating an engine includes determining a relative position between a first camshaft and a second camshaft during a startup event of the engine when the first camshaft is at a first home position and the second camshaft is at a second home position. The first home position is a first preset angular position of the first camshaft relative to a crankshaft. The second home position is a second preset angular position of the second camshaft relative to the crankshaft when the engine is in an OFF state. The method includes generating a first estimate of the first home position. The method also includes diagnosing a mis-build of the engine based on the relative position, the first estimate and a second estimate of the second home position.

摘要： A control system includes a fuel pump control module and a diagnostic module. The fuel pump control module controls a fuel pump to provide fuel to a fuel rail. The diagnostic module controls the fuel pump control module to provide a predetermined amount of fuel to the fuel rail, determines an estimated pressure increase within the fuel rail based on the predetermined amount of fuel, and compares an actual pressure increase within the fuel rail to the estimated pressure increase. The fuel pump control module selectively controls the fuel pump based on the comparison.

摘要： A diagnostic system includes a first pressure monitoring module, a second pressure monitoring module, and a fault determination module. The first pressure monitoring module determines low-lift pressures and high-lift pressures in a cam phaser when a first oil control valve (OCV) moves first valve lifters to the low-lift state and the high-lift state, respectively. The second pressure monitoring module determines low-lift pressures and high-lift pressures in the cam phaser when a second OCV moves second valve lifters to the low-lift state and the high-lift state, respectively. The fault determination module diagnoses a fault in one of the first OCV and the second OCV based the low-lift pressures and the high-lift pressures.

The pressure signal adjustment module detects a maximum peak value of the fluid pressure signal and maintains the maximum pressure signal at the maximum peak value for a peak and hold period. A diagnostic module detects a fault of the camshaft phaser system based on the maximum pressure signal during the peak and hold period.
