摘要： Methods and systems are provided for using a crankcase vent tube pressure or flow sensor for diagnosing a location and nature of crankcase system integrity breach. The same sensor can also be used for diagnosing air filter plugging and PCV valve degradation. Use of an existing sensor to diagnose multiple engine components provides cost reduction and sensor compaction benefits.

摘要： Embodiments for controlling cylinder air flow are provided. In one example, a method for controlling airflow into a cylinder of an engine comprises, if a previous cylinder airflow is different than a desired cylinder airflow, allocating flow into an intake manifold between a throttle and an EGR valve to provide the desired cylinder airflow while maintaining a desired EGR amount in the cylinder. In this way, transient air flow requests may be met without delay while maintaining desired cylinder EGR amounts.

摘要： Methods and systems are provided for raising an exhaust temperature to spin a turbocharger turbine and reduce turbo-lag. Pressurized air is discharged from a boost reservoir into an intake manifold while spark retard is increased to expedite exhaust heating while also increasing a net combustion torque. By expediting turbine spin-up in response to a tip-in, turbo-lag is reduced and engine performance is improved.
