SYSTEM AND METHOD FOR DETECTING STOCHASTIC PRE-IGNITION |
| 摘要 |
A system according to the principles of the present disclosure includes a vibration intensity module and a stochastic pre-ignition (SPI) detection module. The vibration intensity module determines a vibration intensity of an engine over a first engine cycle and a second engine cycle. The first engine cycle and the second engine cycle each correspond to a predetermined amount of crankshaft rotation. The SPI detection module selectively detects stochastic pre-ignition when the vibration intensity of the first engine cycle is less than a first threshold and the vibration intensity of the second engine cycle is greater than a second threshold. |

1. A system comprising:
a vibration intensity module that determines a vibration intensity of an engine over a first engine cycle and a second engine cycle, wherein the first engine cycle and the second engine cycle each correspond to a predetermined amount of crankshaft rotation; and a stochastic pre-ignition (SPI) detection module that selectively detects stochastic pre-ignition when the vibration intensity of the first engine cycle is less than a first threshold and the vibration intensity of the second engine cycle is greater than a second threshold. |
