System and method for preventing stochastic pre-ignition |
| 摘要 |
A system according to the principles of the present disclosure includes a stochastic pre-ignition module and a fuel control module. The stochastic pre-ignition module determines whether operating conditions of an engine satisfy predetermined criteria associated with stochastic pre-ignition. The fuel control module enriches an air/fuel ratio of the engine when the engine operating conditions satisfy the predetermined criteria. |

1. A system comprising:
a stochastic pre-ignition module that determines whether an operating condition of an engine satisfies predetermined criteria associated with stochastic pre-ignition, wherein the engine operating condition includes at least one of a speed of the engine and a load on the engine, and wherein the engine operating condition satisfies the predetermined criteria when at least one of:
the engine speed is greater than a first speed; andthe engine load is greater than a first load; and a fuel control module that enriches an air/fuel ratio of the engine when the engine operating condition satisfy the predetermined criteria. |
