SOME PROBLEMS AND BENEFITS FROM THE HYDROGEN FUELED SPARK IGNITION ENGINE
Induction ignition or back-flashing associated with H2 engines is shown to be caused by deposit ignition or residual gas ignition. Results from single cylinder engine tests show that operation free of induction ignition is possible at all mixtures and compression ratios up to knock and beyond. Test with a typical automotive engine gave thermal efficiencies on average nearly twice that for gasoline. Specific NOx emissions were always less than with gasoline (1/200 to 1/3), but the maximum torque range could not be explored because pyrolised carbon from the lubricant caused induction ignition which could not be eliminated.
