  • Diesel particle filter cleaning method and apparatus
    Patent number: 11058978
    Abstract: A method for cleaning a filter arrangement which has a first fluid connector, a second fluid connector and a filter device which is arranged between the first and second fluid connectors and which has a surface to which contaminants can adhere. The method has the following steps: connecting the first fluid connector to a blowing chamber which has a gas connector, at least partially filling the blowing chamber with a liquid, and generating a cleaning pulse, in which gas is conducted under pressure via the gas connector into the blowing chamber for a first time duration, such that a gas-liquid mixture is forced via the first fluid connector through the filter device and out of the second fluid connector.
