  • Patent number: 9506381
    Abstract: A system according to the principles of the present disclosure includes a valve lift determination module and a fault detection module. The valve lift determination module determines valve lift based on at least one of a first period when a valve is open and N differences between a first value of a valve lift signal generated by a valve lift sensor when the valve is closed and a second value of the valve lift signal when the valve is open, wherein N is an integer greater than one. The fault detection module detects a fault in a valve actuator based on the valve lift.

  • Patent number: 7814874
    Abstract: A camshaft (cam) phaser control system for an engine includes a first camshaft having a first target wheel. A second camshaft has a second target wheel. A cam position sensor detects said first and second target wheels and generates camshaft position data based on said first and second target wheels.

  • Patent number: 7607415
    Abstract: An engine system that compensates for disturbances in a crankshaft signal is provided. The system includes: an error module that computes an error between an ideal period and an actual period of a crankshaft signal; a correction factor module that determines a correction factor based on the error; and a compensation module that applies the correction factor to the actual period of the crankshaft signal.

  • Patent number: 7519465
    Abstract: A method of correlating a rotational position of a crankshaft to a rotational position of a camshaft includes determining a stretch value of a timing connection, which drivingly couples the crankshaft and the camshaft, and calculating a crankshaft to camshaft rotational position value indicative of the rotational position of the crankshaft with respect to the rotational position of the camshaft. The crankshaft to camshaft rotational position value is compensated based on the stretch value to provide a compensated crankshaft to camshaft rotational position value and whether the rotational position of the crankshaft correlates to the rotational position of the camshaft is determined based on the compensated crankshaft to camshaft rotational position value.

  • Publication number: 20080127936
    Abstract: A timing arrangement for an internal combustion engine includes a timing connection having first and second connection features, each of which include respective properties wherein the second property is greater than the first property. A first timing wheel is fixed for rotation with a crankshaft of the engine. The first timing wheel includes first and second adjacent teeth, wherein the first and second adjacent teeth respectively include first and second widths, which correspond to the first and second connection features, respectively.

  • Patent number: 5345817
    Abstract: Engine combustion malfunctions are detected and the responsible cylinder identified by an approach appropriate to the engine operating point by monitoring change in engine speed in a manner insensitive to engine output shaft tooth-to-tooth spacing variations, substantially linear changes in engine speed, and driveline ringing, such as from rough roads or a previously detected misfire. Multiple misfires may be detected in a single engine cycle.
