Tab: Knocking Params

Engine type
In this area, you can select the engine settings suited to your application. In general, these values are contained in the parameter file and must not be manually adjusted:
- In-line, V-type, Irregular
Select the engine type. Select In-line for an in-line engine and V-type for a V-engine. The setting Irregular allows you to define an individual firing sequence in the tab Firing sequence. - 2-, 4-stroke
Select the operating mode of the engine: 2-stroke or 4-stroke. - V-angle
Enter the firing angle for V-engines.
- Cylinder count
Enter the number of cylinders.
Detonation window parameters
In this area, the values are entered for the frequency range in which knocking is likely to occur. These settings are either specified by the parameter file or, if required, determined by MOTORTECH service personnel during engine calibration. In order to ensure the correct functioning of the detonation controller, these values may not be altered.
- Deton. window delay
Delay of the first cylinder ignition measured by the interval following the ignition pulse. The basis is the rising edge of the synchronization pulse. - Deton. window width
Time frame for knock analysis - Knock filter frequency
Characteristic knocking frequency - Ref. filter frequency
Normal frequency of the engine without knocking - Attenuation
Balance between the reference signal (background noises and normal engine vibration) and the knocking signal
- KNOCK, REF
Selection of whether the knocking signal (in %) or the reference signal (in %) should be shown on the knocking intensity display.
