摘要:
The invention describes a preheating device for preheating liquid and/or gaseous fuel for an internal combustion engine, having a fuel inlet (12), having a fuel outlet (24), having a fuel conducting means (10, 18) which connects the fuel inlet (12) to the fuel outlet (24) and which serves to conduct the fuel entering through the fuel inlet (12) to the fuel outlet (24), and having a heat transfer means (4, 16) for transferring heat into the fuel conducting means (10, 18). The special feature of the invention is that the fuel conducting means (10, 18) and the heat transfer means (4, 16) together form an areal heat exchanger arrangement.
