Abstract
Various methods and systems are provided for adjusting a turbine boost control actuator based on a single common reference value. In one example, a method for an engine includes adjusting a turbine boost control actuator to control an intake manifold pressure to a limit, the limit based at least in part on one or more of peak cylinder pressure, turbine speed, and a pressure difference across a turbine.
Claims20
A method for an engine, comprising:
- adjusting a turbine boost control actuator to control an intake manifold pressure to a limit, the limit based at least in part on one or more of peak cylinder pressure, turbine speed, or a pressure difference across a turbine.
A method for an engine, comprising:
- adjusting a turbine bypass valve based on an intake manifold pressure and an intake manifold pressure limit, the intake manifold pressure limit based on a peak cylinder pressure reference, a turbine speed reference, and a third reference of a pressure difference across the turbine bypass valve.
A system, comprising:
- a controller configured to adjust a turbine bypass valve routing exhaust around a turbine of a turbocharger based on an intake manifold pressure measured by an intake manifold pressure sensor and a single common reference pressure, the single common reference pressure based on a peak cylinder pressure, a speed of the turbine, and a pressure differential across the turbine bypass valve relative to respective upper limits.
