System and method for detecting intake manifold combustion

A method comprising monitoring, with at least one sensor 342, 344, 346, 348 in communication with a controller (2, Fig. 2), at least one parameter in an intake manifold 320 of an engine; detecting by the controller (2, Fig. 2), a combustion event in the intake manifold 320 based on output from the at least one sensor 342, 344, 346, 348 and limiting a peak pressure in the intake manifold 320 in response to detecting the combustion event; Systems including a plurality of sensors 342, 344 coupled to the intake manifold 320 and operative to detect at least one parameter in the intake manifold 320, and an engine control module or controller (2, Fig. 2) in communication with the plurality of sensors 342, 344, 346, 348, the controller (2, Fig. 2) being operative to detect a combustion event in the intake manifold 320 based on output from at least one sensor of the plurality of sensors 342, 344, 346, 348, and initiate a control event to limit a peak pressure in the intake manifold 320 in response to detecting the combustion event are also disclosed.
