Abstract

The injection device is intended to ensure equally good atomisation of the fuel for low and high injection rates over the entire load range. For this purpose, the injection device has an injection double valve (31) with a separate low and high rate connection and with separate injection holes (43, 50) for the low and high rate injection. The injection holes (43, 50) are arranged so that the injection holes (43) of the low rate injection valve, smaller in cross-section, inject through the injection holes (50) of the high rate injection valve lying in front of them. <IMAGE>
