摘要：
An engine knock control system for an engine having a turbocharger includes a first module that determines octane scalars indicative of an engine knock propensity for each cylinder of the engine system and a second module that determines a cylinder air mass limit based on the octane scalars. A third module limits a boost output of the turbocharger based on the cylinder air mass limit.
