The widespread acceptance of compressed natural gas (CNG) in domestic automotive applications has been impeded due to the limited driving range of converted vehicles. This inherent problem with the storage of gaseous fuels is driving the search for maximum engine efficiency. The focus of this work is to implement 'intelligent' controllers to optimise the air-fuel ratio of lean burn CNG engines for different operating conditions. Adaptive algorithms are used to estimate parameters of non linear performance models. These models are then used to calculate subsequent inputs for optimal control. An adaptive controller has been implemented on a steady state NG engine and the results detailed.
