D-4,129 C-3227 ENGINE KNOCK CONTROL WITH KNOCK PULSE DURATION ADJUSTMENT Abstract of the Disclosure A vehicle mounted, spark ignited, internal combustion engine subject to bursts of ringing knock vibration of varying duration corresponding to knock of varying intensity includes apparatus effective to generate pulses in response to the bursts and of corresponding duration. Further apparatus delays the trailing edge of each pulse by a common predetermined duration to favorably reduce the ratio of the durations of such pulses before application to apparatus effective to control a knock reducing parameter of the engine. The reduced ratio of duration between short and long pulses provides more uniform control over the total range of knock intensity. The engine may also include apparatus to delay the leading edge of each pulse by a common predetermined duration to eliminate short noise pulses and improve the knock signal to noise ratio. If so, this apparatus is inserted prior to the trailing edge delay apparatus and the common predetermined duration of the latter is greater than that of the former.
