Embodiment Construction

[0032] exist figure 1 An engine control unit 10 is shown in , which is electrically conductively connected to an ignition start switch 12 , a pre-ignition display 14 , an ignition pin control 16 and a cooling water thermometer 18 via associated lines indicated by dashed lines.

[0033] The temperature of the cooling water located on the associated engine 20 can be determined by the engine control unit 10 by interrogating the cooling water thermometer 18 and the ignition pin control 16 can be controlled according to the specification of the ignition switch 12 . The ignition pin controller itself controls the ignition pin spark plug 22 , which is operatively coupled to the ignition pin controller 16 via lines likewise indicated by dashed lines.

[0034] A filter device 26 , which serves to filter the fuel supplied to the engine 20 , is also connected via a line 24 to the ignition pin controller 16 , which is specially adapted to the heating task.

[0035] The filter device 26 i...

Abstract

The device has a filter element (32) arranged in a filter housing (28). A heater is provided for heating up medium flowing through the filter element, and a water sensor (50) is provided for detecting water collected in the filter housing. The heater is designed together with a water sensor as a structural unit. A central control device (16) is arranged in the filter housing for controlling a structural unit and heating performance of the heater and evaluating water level in the water sensor. An independent claim is also included for a method for operating a filter device.

Description

technical field [0001] The invention relates to a filter device, in particular a liquid filter, with a filter element arranged in a filter housing, with a heating device for heating the medium flowing through the filter element and with a filter for identifying A water sensor for water, wherein the heating device and the water sensor constitute a structural unit. The invention also relates to a method for operating a filter device, in particular a liquid filter, comprising a filter element arranged in a filter housing, a heating device for heating the medium flowing through the filter element and a Water sensor for identifying water collected in the filter housing. Background technique [0002] In order to ensure uniform and good filtration under different operating conditions for the filter device, in particular the liquid filter, in the fuel supply of a motor vehicle, it is known to provide a respective heating device on the filter device. By means of the heating device,...
