摘要： The invention relates to a method for adapting transient compensation on the basis of a lambda-value change to operate an internal combustion engine comprising a combustion chamber. The combustion chamber comprises a first inlet port, connected to a first intake tube, in which tube a first injection valve is arranged. The combustion chamber further comprises a second inlet port, connected to a second intake tube, in which tube a second injection valve is arranged. In a normal mode of operation, a predetermined fuel quantity is injected, the predetermined fuel quantity being composed of a first fuel quantity to be injected through the first inlet valve and a second fuel quantity to be injected through the second inlet valve. In a first method step, the first injection valve remains closed and in a second method step, the first injection valve is opened again, wherein in the second method step, a first test fuel quantity is injected into the combustion chamber via the first inlet port and a second test fuel quantity via the second inlet port, the first test fuel quantity and the second test fuel quantity adding up to the predetermined fuel quantity.

摘要： A fuel injection device for a multi-cylinder internal combustion engine is provided, said device comprising an air flow path (18) for feeding combustion air, said path having flow channels (17) leading to the individual cylinders (11), the flow channels being separated from one another at the ends, and comprising a dual injection system with a first group of fuel injection valves (19) that inject fuel directly into each cylinder (11) and with a second group of fuel injection valves (20) that inject fuel into the flow channels (17). To reduce the manufacturing costs for the fuel injection device, with concomitant weight reduction and system simplification, the fuel injection valves (20) of the second group are designed as multi-stream injection valves (26, 27) that spray at least two separate fuel streams (24, 25) at the same time, and the valves are disposed in the air flow path (18) such that the sprayed fuel streams (24, 25) enter different flow channels (17).
