摘要： A system according to the principles of the present disclosure includes a timing control module and a diagnostic module. The timing control module controls engine valve timing by sending fluid to an advancing chamber of a cam phaser to adjust the cam phaser to an advanced position and by sending fluid to a retarding chamber of the cam phaser to adjust the cam phaser to a retarded position. The diagnostic module identifies a fault in a variable valve lift (VVL) mechanism based on a first difference between an advancing pressure of the advancing chamber and a retarding pressure of the retarding chamber.

摘要： A control system for an engine is presented. The control system can include a transition period waveform monitor module, a stuck fuel injector detection module, and a fuel injection control module. The transition period waveform monitor module measures an electrical signal of a fuel injector upon deactivation of the fuel injector. The stuck fuel injector detection module detects a stuck fuel injector when an accumulated deviation of the electrical signal from a parameterized estimated reference waveform is outside of a predetermined range. The fuel injection control module controls fuel injection in the engine based on the detection of the stuck fuel injector.

摘要： A system for diagnosing a switchable roller finger follower (SRFF) and an oil control valve (OCV) includes a signal monitoring module and a fault detection module. The signal monitoring module receives at least one of an individual cylinder fuel correction (ICFC) signal and an air/fuel ratio imbalance (AFIM) signal when: an engine speed signal is within a predetermined range of speed; an engine load signal is within a predetermined range of load; and a charcoal canister vapor signal is within a predetermined range of flow rate. The fault detection module detects a fault of at least one of a SRFF and an OCV based on an exhaust gas recirculation value and at least one of the ICFC and AFIM signals. The ICFC and AFIM signals are generated based on: an engine position signal; and at least one of an oxygen signal and a wide range air fuel signal.

摘要： An improved method of operation for an electromechanical purge valve of a vehicle evaporative emission control system reduces the activation level of the purge valve below a nominal minimum level by a variable offset amount under specified operating conditions to lower purge flow. Specifically, the low flow control is permitted when the fuel in the purge vapor being drawn into the engine exceeds a calibrated percentage of the engine fuel requirement and the activation level of the purge valve has been reduced to the nominal minimum, provided that the system voltage level is at or above a specified value. When low flow control is permitted, the offset amount is incrementally increased so long as the engine fuel control is able to maintain the air/fuel ratio error at or below a calibrated amount, and incrementally decreased when the low flow control is no longer permitted or the air/fuel ratio becomes lean enough to potentially degrade combustion stability.

摘要翻译： 用于车辆蒸发排放控制系统的机电清洗阀的改进的操作方法将清洗阀的活化水平在标称最小水平下降低指定操作条件下的可变偏移量以降低吹扫流量。 具体地说，当吸入发动机的净化蒸气中的燃料超过发动机燃料需求的校准百分比时，允许低流量控制，并且将净化阀的活化水平降低到额定最小值，只要系统电压 级别等于或高于指定值。 当允许低流量控制时，只要发动机燃料控制能够将空气/燃料比误差维持在或低于校准量，偏移量就逐渐增加，并且当不再允许低流量控制时递增地减小， 空气/燃料比变得足够稀薄以潜在地降低燃烧稳定性。
