Abstract

Zur Sicherstellung eines gleichmäßigen Temperaturniveaus von einzelnen Zylindern einer Brennkraftmaschine zugeführtem Kraftstoff wird vorgeschlagen, in eine kraftstofführende Ausnehmung (2) eines Zylinderlinderkopfes (1) einen mit Abströmöffnungen (6) und Stützen (8) versehenen Einsatz (3) einzubringen, welcher durch seine Wirkung als Gegenstromwärmetauscher und durch die Vermischung mit den durch die Abströmöffnungen (6) austretenden Teilkraftstoffströmen für eine gleichmäßige Temperatur des über Querleitungen (7) zu den Injektoren geführten Kraftstoffes sorgt.

Figure 00000001
In order to ensure a uniform temperature level of fuel supplied to individual cylinders of an internal combustion engine, it is proposed to insert an insert (3) provided with outflow openings (6) and supports (8) in a fuel-carrying recess (2) of a cylinder head (1) Counterflow heat exchanger and by mixing with the partial fuel flows emerging through the outflow openings (6) ensures a uniform temperature of the fuel led via cross lines (7) to the injectors.
