Abstract

Hydrogen will dramatically change the way we live in the future. While some
published literature details the practical uses and applications of hydrogen as a
fuel, little evidence is available in the public domain on the conversion
technologies and associated emission data of this emerging technology.
In this thesis, the conversion of a petrol engine to run on hydrogen is proposed
and executed from first principles. Research was directed on key areas such as
fuel storage, delivery and safety systems as well as integration of an effective
engine management system. The performance of the vehicle in TARGA Tasmania
2006 clearly establishes its reliability and demonstrates a functional prototype
that attests to the viability of hydrogen as an alternative fuel.
As part of this investigation, neural network models based on experimental data
acquired from a comprehensive range of engine operating conditions are used for
the prediction of emissions such as carbon dioxide, carbon monoxide, unburnt
hydrocarbons and oxides of nitrogen. These predictions are based upon study of
the qualitative and quantitative effects of engine process parameters such as
mass air flow, RPM, air-to-fuel ratio, exhaust gas temperature and engine power
on the output emissions.
The predictive models show excellent accuracy in estimating emissions for various
engine operating conditions on both hydrogen and petrol. This model when
integrated into the existing engine management system could act as a "virtual
sensor" for emission prediction. This provides an avenue for further reduction of
emissions based on greater understanding of the effects of engine process
parameters on emissions.
