| 摘要 |
The present invention relates to an injection system for an internal combustion engine operated with liquefied petroleum gas and with a plurality of injection nozzles for the direct injection of fuel into the cylinders of the internal combustion engine, which injection system comprises the following: a fuel supply system in which fuel is held under a gas pressure; a high-pressure pump in order to make fuel available which stands under injection pressure; a high-pressure line which is connected with the high-pressure pump in order to supply the fuel being under injection pressure to the injection nozzles. A secure operation is achieved in such a way that a control line is provided further which can optionally be brought into connection with the injection nozzles, with fuel being present in the control line having a pressure which is higher than the gas pressure.
