    Method and preheating time control apparatus (2) for a number n of glow plugs that are excited with a signal modulated by pulse width with predetermined period, applying voltage to each glow plug (1) during a power-up fraction of the period and not applying tension during the rest of the period. The spark plugs of the glow plugs (1) are arranged during the period to apply the voltage simultaneously to a minimum number of glow plugs (1) so that a current added through all the glow plugs (1) remains uniform. In addition, means are provided which, when the ignition fraction is less than one of the period, measure a voltage difference of the spark plugs (1) while a glow plug (1) voltage is applied.
