Abstract
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.
