Abstract
A wheel spin detector monitors the speeds of vehicle wheels and supplies a signal to an engine management system when excessive wheel spin is detected. The engine management system includes a fuel controller which, in response to the signal from the detector, reduces engine torque by inhibiting the supply of fuel to one or more cylinders of the engine such that either all cylinders are continuously fuelled or continuously unfuelled or one and only one cylinder is intermittently fuelled. When an unfuelled cylinder is fuelled again, the mixture supplied to it may be temporarily enriched.
