Embodiment Construction

[0023] exist figure 1 The various elements of a device for controlling an internal combustion engine are schematically shown in . The internal combustion engine is denoted by 100 . Fuel is supplied to internal combustion engine 100 via injector 110 as a function of control signal A. FIG. Arranged on the internal combustion engine is a first sensor 115 which outputs a signal indicating the pressure P in the combustion chamber. Furthermore, a second sensor 120 is provided, which supplies different signals which characterize the operating state of the internal combustion engine. For example, it can be provided here that a signal N relating to the rotational speed of the internal combustion engine is output. The output signals of the first sensor 115 and the second sensor 120 reach the control unit 130 . Furthermore, the control unit processes the output signals of the environmental sensors 135 . Control unit 130 calculates an actuation signal A for actuating injector 110 fro...

Abstract

The invention relates to a method, a computer programme, an electronic storage medium and an electronic control device for controlling an internal combustion engine, in which fuel injection is divided into at least three partial fuel injections. The interval between the partial fuel injections and / or the distribution of the injected fuel quantities is predefined according to a parameter that characterises the combustion sequence.

Description

technical field [0001] The invention relates to an electronic controller, a method, a computer program and an electronic storage medium for controlling an internal combustion engine of the type described in the independent claims. Background technique [0002] A method and a device for controlling an internal combustion engine are known from DE10040117. There, the injection process is divided into pre-injection, main injection and post-injection. The main injection is in turn divided into a number of sub-injections. [0003] Generally speaking, for a diesel internal combustion engine with a common rail system, the injection process includes one or two pre-injections, a main injection and, if applicable, an immediately additional post-injection. These jets create torque. In this case, the combustion of the pilot injection quantity and the main injection quantity is decisive for combustion noise. The immediately additional post-injection is used for soot oxidation and has ...
