摘要: A vacuum pump onboard a vehicle provides vacuum for a brake booster and to control the electronic vacuum regulation valve (EVRV) valve of a wastegate on a turbocharger. Commands to the EVRV are based on an operating condition of an engine and the vacuum level in the vacuum system. In one example, a vacuum sensor is provided to determine vacuum proximate the EVRV. In another example, the vacuum proximate the EVRV is modeled based on the vacuum at the brake booster, which may be determined by a vacuum sensor coupled to the brake booster.

摘要: Various systems and methods are described for an exhaust gas recirculation (EGR) system coupled to an engine in a vehicle. One example method comprises, calculating an EGR mass flow from a difference between measurements of clean air mass flow and total mass flow, and correcting for a transient mass flow error.

摘要: Various systems and methods for controlling a turbocharger of an engine via a wastegate are described. In one example, actuation of the wastegate is limited when outside a range, the limits of the range varying with boost pressure, turbine inlet pressure, turbine outlet pressure, and atmospheric pressure. In this manner, a tracking error may be reduced when controlling the boost pressure and using the boost pressure to actuate the wastegate in a boost-based wastegate configuration.

摘要: An engine with a two vacuum sources is disclosed. In one example, a valve position is adjusted in when engine load is low and intake manifold pressure is low to arbitrate vacuum between the two vacuum sources. The approach may increase engine operating efficiency during at least some conditions.
