Abstract: There is described a system for analyzing an air condition. The system comprises a detection unit configured for detecting of detection signals indicative of a bacteria-related contamination of an evaporator and/or an air filter of the air condition, an analyzing unit configured for analyzing of a level of contamination of the evaporator and/or the air filter based on the detection signals, and an output unit configured for outputting the analyzed level of contamination of the evaporator and/or the air filter to a user.

Abstract: A cleaning device (100) for cleaning an interior of a device to be cleaned (102), wherein the cleaning device (100) comprises an adapter (104) for mounting the device to be cleaned (102), a cleaning medium reception chamber (106) for receiving cleaning medium driven through the device to be cleaned (102) when mounted on the adapter (104), and a drive unit (108) for driving cleaning medium from a cleaning medium reservoir (110) through the device to be cleaned (102), when mounted on the adapter (104), and into the cleaning medium reception chamber (106).

Abstract: The present invention relates to the use of at least one, optionally alkylated diarylamine in a fuel or a fuel additive for cleaning the combustion chamber of an internal combustion engine, in particular of a motor vehicle engine. A further aspect relates to a method for cleaning the combustion chamber of an internal combustion engine during the operation of the internal combustion engine by burning a fuel, wherein the fuel contains a fuel additive comprising at least one, optionally alkylated diarylamine.

Abstract: The invention relates to a blasting probe for introducing a granular blasting material into a cavity, in particular into a narrow coked cavity such as an inlet channel of a valve of an internal combustion engine, in particular for cleaning said cavity, comprising a blasting pipe (connectable, at a rear end thereof, to a blasting material feeding line, and a blasting nozzle at the front end of the blasting pipe, said blasting nozzle having at least one outlet opening for the blasting material which is radial with respect to the longitudinal axis of the blasting pipe and which is associated with a deflector surface arranged obliquely with respect to the longitudinal axis of the blasting pipe.

Abstract: A method for cleaning particle filters in exhaust gas systems of combustion engines, in particular diesel engines in vehicles. In order to clean a particle filter, a noncombustible, ash-free cleaning fluid is sprayed into the particle filter at high pressure by a spray nozzle, across an area of said filter through which the exhaust gas flows during the operation of the combustion engine, in a quantity such that the interior of the particle filter is substantially completely soaked. Also provided is an apparatus for carrying out the method, which includes a container containing, under pressure, the fluid to be injected into the particle filter to be cleaned, an outlet valve, and a spray nozzle, which can be connected to the outlet valve via a hose and can be inserted into a space in the exhaust gas system situated before or after the particle filter.

Abstract: The invention relates to a method for cleaning coked cavities, in particular inlet, channels (10) and valves (15) of an internal combustion engine (12), comprising the following steps: introducing an alkaline liquid into a cavity to be cleaned; heating the alkaline liquid; and extracting the alkaline liquid and the dirt particles contained therein by suction from the cavity. Said method can be carried out especially simply and effectively using a device comprising a first probe (21), which is provided at the leading end thereof with one or more nozzles (23) for injecting an alkaline liquid into the cavity to be cleaned and which is connected at the other end thereof to the delivery side (24) of a pump (25), wherein warmed alkaline liquid can be supplied to the intake side (26) of said pump. A second probe (22) is provided for extracting the alkaline fluid and the dirt particles contained therein by suction from the cavity.

Abstract: The present invention relates to a method and to an apparatus for cleaning particle filters in exhaust gas systems of combustion engines, in particular diesel engines in vehicles. In order to clean a particle filter in a simple and economical manner without the need to remove the particle filter, a noncombustible, ash-free cleaning fluid is sprayed into the particle filter (25) at high pressure by means of a spray nozzle (14), across an area of said filter through which the exhaust gas flows during the operation of the combustion engine, in a quantity such that the interior of the particle filter is substantially completely soaked.
