Fuel injection system and preheating device

摘要

A fuel injection system for an internal combustion engine may include at least one distributor unit to supply liquid fluid and a plurality of preheating systems each connected to the distributor unit. The respective preheating systems may have a preheating chamber and at least one heating element. A plurality of connection nozzles may each be connected to respective preheating systems. A fuel path may lead from the distributor unit through the respective preheating chambers to the respective injection nozzles of the plurality of preheating systems. The respective preheating systems may include a housing having an inlet and an outlet. The housing may be connected via a plug-in connection on the inlet to the distributor unit and via a plug-in connection on the outlet to the respective injection nozzle.
