Abstract
A method and a device for controlling an internal combustion engine, in which first device meters fuel to the internal combustion engine that is burned in the internal combustion engine. Second device performs an exhaust gas aftertreatment. A post-injection takes place, in the case of which, following the combustion, the first device meters fuel which reacts in the second device.
Claims10
A method for controlling an internal combustion engine, comprising the steps of:
- metering fuel to the engine using a fuel metering device, the fuel being burned in the engine;
- performing an exhaust gas after treatment using an exhaust gas after treatment device;
- following a combustion of the fuel, performing a post-injection of additional fuel into the engine using the fuel metering device, the additional fuel reacting in the exhaust gas after treatment device,
- wherein the engine includes four or six cylinders, the cylinders being allocated to at least two banks such that cylinders which follow one another in a firing order are allocated to different banks.
A method for controlling an internal combustion engine, comprising the steps of:
- metering fuel to the engine using a fuel metering device, the fuel being burned in the engine;
- performing an exhaust gas after treatment using an exhaust gas after treatment device;
- following a combustion of the fuel, performing a post-injection of additional fuel into the engine using the fuel metering device, the additional fuel reacting in the exhaust gas after treatment device,
- wherein the engine includes eight cylinders, the cylinders being allocated to first and second banks such that two of the cylinders that follow one another in a firing order are allocated to the first bank and a following two of the cylinders are allocated to the second bank.
A device for controlling an internal combustion engine, comprising:
- a first arrangement metering fuel to the engine, the fuel being burned in the engine;
- and
- a second arrangement performing an exhaust gas after treatment, the first arrangement performing a post-injection of additional fuel into the engine following a combustion of the fuel, the additional fuel reacting in the second arrangement, and
- wherein the engine includes four or six cylinders, the cylinders being allocated to at least two banks such that cylinders which follow one another in a firing order are allocated to different banks.
