System for controlling engine fueling to limit engine output power
First Claim
1. A method for controlling fueling of an internal combustion engine, the engine including an intake manifold, one or more exhaust manifolds and a turbocharger coupled between the intake and exhaust manifolds, the method comprising:
- determining ambient pressure,estimating an air inlet density of a compressor of the turbocharger as a function of the determined ambient pressure,determining a maximum value of engine exhaust temperature as a function of the air inlet density of the compressor of the turbocharger,measuring engine exhaust temperature,determining an error value as a function of the maximum value of the engine exhaust temperature and the measured engine exhaust temperature, andlimiting fuel supplied to the engine based on the error value.

Abstract
A method for controlling fueling of an internal combustion engine is provided. The engine may include an intake manifold, one or more exhaust manifolds and a turbocharger coupled between the intake and exhaust manifolds. The method may comprise estimating an operating condition of the turbocharger, determining a maximum value of an operating parameter as a function of the estimated operating condition of the turbocharger, measuring a value of the operating parameter, determining an error value as a function of the maximum value of the first operating parameter and the measured value of the operating parameter, and limiting fuel supplied to the engine based on the error value.
