Abstract
A formation of deposits on a fuel injector is suppressed by controlling the temperature of the nozzle holder of the fuel injector around the nozzle to maintain at least a part of the fuel remaining on the nozzle holder surface after the fuel injection in a liquid state, to thereby hold precursors of the deposits in the liquid fuel to permit the precursor to be blown out from the nozzle holder surface by a subsequent fuel injection flow.
