Abstract
A method of controlling an air to fuel ratio of an internal combustion engine may include receiving a request for a modification of a first flow of fuel to at least one combustion chamber, modifying the first flow of fuel in response to the request, receiving a first signal indicative of a first air supply condition, displacing a second flow of fuel in response to receiving the signal and controlling the modification of the first flow of fuel by the displacement of the second flow of fuel.
