SYSTEM AND METHOD FOR DETERMINING LOCATION AND VALUE OF PEAK FIRING PRESSURE |
| 摘要 |
A system includes a combustion engine having an intake manifold and an exhaust manifold, an exhaust gas recirculation (EGR) system coupled to the combustion engine and configured to route exhaust generated by the combustion engine from the exhaust manifold to the intake manifold, and a first knock sensor coupled to the combustion engine and configured to measure vibrations of the combustion engine and output a first vibration signal. The system also includes a controller communicatively coupled to the combustion engine, the knock sensor, the EGR system, or any combination thereof. The controller is configured to determine a peak firing pressure (PFP) within the combustion engine and control operations of both the combustion engine and the EGR system based on the PFP. |

1. A system, comprising:
a combustion engine comprising an intake manifold and an exhaust manifold; an exhaust gas recirculation (EGR) system coupled to the combustion engine and configured to route exhaust generated by the combustion engine from the exhaust manifold to the intake manifold; a first knock sensor coupled to the combustion engine and configured to measure vibrations of the combustion engine and output a first vibration signal; and a controller communicatively coupled to the combustion engine, the knock sensor, the EGR system, wherein the controller is configured to determine a location of peak firing pressure (PFP) or a value of absolute pressure within the combustion engine based on the first vibration signal, and control operations of both the combustion engine and the EGR system based on the PFP or the absolute pressure value. |
