Abstract

A fuel injection system (4) for an internal combustion engine has a low-pressure pump for delivering fuel from a fuel tank. The fuel is fed upstream of an injector (11) of the fuel injection system (4) to a mixing device (14). The mixing device (14) has a mixer housing (18) with a fuel connection (15) for receiving fuel and with at least one coolant connection (17; 28; 33) for receiving a coolant. For the purpose of bringing about efficient mixing of the fuel and the coolant, before a collision of a fuel jet (40) of the fuel and a coolant jet (41) of the coolant, the two fluid jets (40, 41) are formed to be at least partially aligned in the same direction.
