An input signal indicative of abnormal combustion occurring during an operating cycle of an internal combustion engine 202 is received (510, fig 5). In response to the abnormal combustion, a target lean air-fuel ratio is determined (520, fig 5). The determined target lean air-fuel ratio is leaner than an air-fuel ratio determined for the operating cycle during which the abnormal combustion occurred. A fuel injection control signal is output (530, fig 5). The fuel injection control signal causes injection of a quantity of fuel into a combustion chamber 218 during a first operating cycle after the operating cycle in which the abnormal combustion occurred, the quantity of fuel being configured to produce the target lean air-fuel ratio. The fuel may be hydrogen. The internal combustion engine has one or more sensors to detect abnormal combustion. A vehicle comprises the internal combustion engine.
