Spark plug thermal characteristics were investigated for both propane and butane at various altitudes; these tests show that under ordinary conditions, if correct spark plug heat range is installed at sea level, selection does not need to be changed for higher altitude operation; operating spark plug temperatures were lower with butane as compared with propane and may warrant, in some instances, hotter heat range; knock-limited spark advance increased with altitude, but decreased with increasing compression ratios; there is no significant spark plug voltage requirement change under running conditions, as altitude is increased from roughly sea level to 8000 ft.
