Abstract
A system and method for reducing engine knock associated with an internal combustion engine. An exhaust gas recirculation sub-system is fluidly connected to the internal combustion engine and includes a compressor and an exhaust gas storage tank fluidly connected to the compressor. In response to measuring that engine knock is occurring, compressed exhaust gas is injected from the exhaust gas storage tank into a combustion chamber of the internal combustion engine.
