Injection arrangement for an internal combustion engine and method for fuel injection

A fuel injection arrangement for an internal combustion engine, comprising:

• at least one intake pipe leading to at least one combustion space;
• at least one inlet valve arranged between the combustion space and the intake pipe;
• and
• at least two fuel injection valves assigned to each of the at least one combustion space, independent of a number of inlet valves, the at least two fuel injection valves opening into the at least one intake pipe, at least one of the at least two fuel injection valves being provided with an evaporator device for emitting a fuel vapor;
• wherein the at least two fuel injection valves are aligned such that the fuel vapor is emitted directly at the at least one inlet valve, away from walls of the intake pipe.

A method for injecting fuel into an internal combustion engine having at least one combustion space, at least one intake pipe, and at least two fuel injection valves, the at least one intake pipe leading to the at least one combustion space, the at least two fuel injection valves opening into the at least one intake pipe, the method comprising the steps of:

• structuring one of the at least two fuel injection valves such that it emits a fuel vapor;
• injecting fuel into each of the at least one combustion space via the at least two fuel injection valves, the at least two fuel injection valves corresponding to the at least one combustion space;
• operating the one fuel injection valve which emits the fuel vapor for 60 to 90 seconds during a cold start of the internal combustion engine;
• operating, subsequent to the operating of the one fuel injection valve which emits the fuel vapor, another fuel injection valve, without an evaporator device, of the at least two fuel injection valves;
• and
• switching, under control of an electronic control device operating under at least one processed parameter of the internal combustion engine, between the operating of the one fuel injection valve which emits the fuel vapor and the another fuel injection valve without the evaporator device;
• wherein the step of switching takes place when a catalytic converter, which treats exhaust gases, has reached a conversion temperature.
