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 engine system includes an engine having an intake manifold and a turbocharger that supplies compressed air to the intake manifold. An engine control module calculates a desired pre-throttle pressure of air before the throttle and calculates a desired manifold air flow into the engine. The engine control module determines a desired pre throttle pressure area based on the desired air per cylinder, desired manifold pressure and RPM and generates control signals to control the engine with the turbocharger.
