The invention relates to a method for preventing icing of an injection system of an internal combustion engine of a motor vehicle having a high-pressure fuel pump to which, in addition to fuel, watercan also be supplied via a feed line, and wherein, when the motor vehicle is stopped, water still located in a wide region of the feed line is extracted, at least if required. For this purpose, a conveying device provided for conveying water to the high-pressure fuel pump is operated with the direction of rotation reversed. When the motor vehicle or the internal combustion engine is re-started, that region of the feed line from which water located therein has previously been extracted is flushed with water, the air located therein beings discharged into the surroundings. 本发明涉及一种用于防止机动车内燃机的喷射系统结冰的方法，该喷射系统具有高压燃料泵，该高压燃料泵除了燃料之外也可经由供应管路被供应水，并且在机动车停车时至少根据需要将仍留在供应管路的大部分区域中的水吸走。为此使设置用于向高压燃料泵输送水的输送装置以反转的旋转方向运行。当机动车或内燃机重新启动时，用水冲洗供应管路的先前位于该区域中的水已被吸走的区域，其中，位于该区域中的空气被排放到环境中。
