Problems solved by technology

The disadvantage of this approach is that it does not take into account persistent changes in operating conditions
It may thus not be possible to suppress knocking in the initial operating state, so that the method is ineffective
In the case of changing operating conditions, it is impossible to reproduce the original operating state
The engine is thus operated with knocking, or possibly with reduced power in a non-optimal operating range, or the engine has to be switched off

Embodiment Construction

[0029] figure 1 Combine image 3 A block diagram showing a method and device for adjusting the operating state of an internal combustion engine according to an embodiment of the present invention. In the first step S1, the sensor 2 detects data, and in subsequent steps which will be described in detail below, an adjustment process is performed with the engine controller 1 based on the data.

[0030] In the illustrated embodiment, the device has an engine controller 1 and a plurality of sensors 2. According to the data transmitted by the sensor 2, the engine controller 1 obtains the operating state (Z1) of the engine (W) and the optimal operating area, and adjusts the set engine operating parameters so that the operating state (Z1) is kept at the most The best operating area (W), or enter the best operating area (Wn).

[0031] In the illustrated embodiment, the internal combustion engine, which is not shown in detail, is a gas-gasoline engine operating at rest. In the illustrated...

Abstract

The invention relates to a method for changing the operating state of an internal combustion engine. Data representing the operating state of the internal combustion engine are detected by at least one sensor and transmitted to the regulating device. On the basis of these data, the control device determines an optimal operating range of the internal combustion engine and adapts the operating state of the internal combustion engine to the optimal operating range target unambiguously in that at least for the engine operation intended for the combustion process The parameters determine the setpoints used to maintain or achieve the optimum operating region and adjust the actual values ​​of the engine operating parameters to the setpoints.

Description

Technical field [0001] The invention relates to a method for changing the operating state of an internal combustion engine. The present invention also relates to the application of the method, and also relates to a device for implementing the method and a regulating device used for the method. Background technique [0002] It is preferable to utilize the internal combustion engine in an optimal operating region suitable for the purpose of use of the engine. The characteristic of the usual optimum operating area is, for example, the minimum fuel consumption during operation. The operating state of the internal combustion engine is therefore preferably maintained in this optimal operating region. However, the combustion quality and operating state of the fuel-air mixture used depend on many operating conditions that cannot be maintained continuously, such as fuel composition, suction air temperature, fuel quality, and remaining gas content in the cylinder. [0003] Therefore, it m...
