Estimating the term…
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.
A mixing device for a fuel injection system of an internal combustion engine, the fuel injection system having a low-pressure pump for delivering fuel from a fuel tank to the mixing device and subsequently to an injector of the fuel injection system, the mixing device comprising a mixer housing with a fuel connection for receiving fuel, and at least one coolant connection for receiving a coolant, the mixer housing having a mixing chamber configured so that a fuel jet of the fuel and a coolant jet of the coolant in the mixing chamber of the mixer housing are at least partially aligned in a common direction in the mixing chamber to bring about efficient mixing of the fuel and the coolant as a fuel-coolant mixture before a collision of the fuel jet of the fuel and the coolant jet of the coolant in a mixing chamber.
