In order to facilitate practical application of hydrogen fueled engines with external mixture formations. it is necessary to determine the cause of backfire and to identify appropriate countermeasures. It has been found in our study that one of the causes of backfire is attributed to the electric discharge which occurs after the ignition of the spark plug when the pressure in the cylinder becomes low enough to discharge the electric charge remaining in the ignition system. The electric charge in the plug cable remains much longer when hydrogen is used as the fuel than when gasoline is used. In other words, the number of ions produced from hydrogen-air combustion after the ignition of the spark plug is less than that from gasoline-air combustion, so it is difficult for the ion current to flow out through the gap of the spark plug. It has been found in our experiments that backfire takes place when the electric discharge occurs during the intake stroke and that engine operation could be performed up to an excess air ratio of λ=1 without any backfire at a low engine speed when the ignition system was modified such that no electric charge remained in the spark plug cable.
