Abstract
A method for controlling the fuelling rate for an internal combustion engine including: a) controlling the fuelling rate in a fuel led control mode whereby the fuelling rate is controlled as a function of the operator demand on the engine during at least a portion of low engine load operation; b) controlling the fuel rate in an air led control mode whereby the fuelling rate is controlled as a function of the air flow rate to the engine during at least a portion of medium-to-high engine load operation; and c) providing a point of transition between the two control modes wherein each control mode provides substantially the same predetermined fuelling rate.
