Definition of three types of abnormal combustion, such as spark knock, wild ping, and rumble; another low pitched noise observed in 1958 engines during high speed is thud, obtained in absence of surface ignition; experiments carried out with test cars equipped with engines modified to 12:1 compression ratio to determine characteristics of thud and how it is affected by fuel consumption.
