Автор: Carlos A. Rosero
Принадлежит: Cummins Inc

Systems and methods for detecting, predicting and/or responding to faults are disclosed. In one form, a sensor can be operatively coupled to an engine system having a component and a control system is coupled to the sensor. The sensor can be structured to monitor the engine system and generate corresponding sensor information. The control system can be structured to: generate an operational signature based on the sensor information, estimate whether a fault (e.g., a mechanical fault of the component and/or a performance fault of the engine system) exists based on the operational signature, determine an engine operating mode adjustment if the fault exists and output the engine operating mode adjustment to an output device. Systems and methods for increasing the accuracy by which faults are detected and/or predicted are also disclosed. The engine operating mode adjustment can be applied to protect engine system components from being undesirably damaged to faults.

Adsorbent structures for removal of water and fuel contaminants in engine oil

Номер: US20120103286A1
Автор: Gregory Mordukhovich
Принадлежит: GM GLOBAL TECHNOLOGY OPERATIONS LLC

Devices and methods for removal of condensed, blow-by contaminants with small molecular dimensions from the circulating lubricating engine oil of internal combustion engines, including automotive engines, with a positive crankcase ventilation system are disclosed. These condensable blow-by contaminants include water, alcohols and hydrocarbons with preponderantly seven or fewer carbon atoms. A macroporous structure comprising alumino-silicate particles with micro-pores is at least partially immersed in the circulating oil. The micro-pores are sized to adsorb the small, condensed, blow-by, contaminant molecules but not the larger oil molecules. The particles may be multi-layered, with an inner layer adapted for adsorption of polar molecules. Adsorption is most extensive at lower oil temperatures and decreases as the oil temperature increases. Thus at low temperatures the contaminant molecules may be adsorbed, removed from the oil and temporarily stored in the micropores. At high temperatures some of the contaminants will desorb and be re-incorporated in the oil. The desorbed contaminants will be carried with the higher temperature oil into the engine crankcase where they may vaporize and be removed by the engine positive crankcase ventilation system.

A method of cleaning a reciprocal direct injection compression ignition engine from carbonaceous deposits formed in the course of its operation comprising switching engine to a McNeil cycle combustion mode by increasing the inlet air temperature to 60-200° C.; switching from normal operational fuel to a polyol or a blend of polyols , running engine on a polyol till the CO level in the exhaust gas flue and exhaust temperature return to normal levels , switching fuel supply back to normal operational fuel and combustion mode to standard.2. A method according to claim 1 , where polyol is propane-1 claim 1 ,2 claim 1 ,3-triol. This invention relates to a method of cleaning and decarbonising internal surfaces of a direct injection compression ignition engineCompositions and methods have been devised that flush engines with cleaning fluid or other types of chemical solvent solutions in an attempt to clean these surfaces. In one such system, a separate canister containing a liquid mixture of engine fuel and injector cleaning solvent is connected to the fuel line, and the engine is operated using the fuel solvent mixture. Additionally, typical conventional solvent and detergent cleaning fluids are mixed with gasoline and the automobile engine is run during cleaning. When these cleaning fluids are successful in dislodging or removing carbon deposits they essentially only move the deposits downstream to the combustion chamber and/or exhaust system. Emissions during such a ‘cleaning treatment process’ are dramatically increased as the carbon and sludge moves further into the engine.It is well known that reciprocating internal combustion engines tend to form carbonaceous deposits on the surface of engine components, such as, fuel injectors.

METHOD FOR SIMULATING EXTREME OR DEFECTIVE SOLENOID VALVES FOR DEMONSTRATING THE FAILURE EFFECT AND FOR DETECTING FAULTS IN ORDER TO CERTIFY A VEHICLE DIAGNOSIS SYSTEM

Номер: US20180023720A1
Автор: Pedersen Gerulf, TRAVERSA Piergiacomo
Принадлежит: SCHAEFFLER TECHNOLOGIES AG & CO. KG

The invention relates to a method for simulating malfunctioning solenoid valves for an internal combustion engine by influencing an activation time and a deactivation time of the solenoid valve. A current with a specified modifiable current strength flows through the solenoid valve in order to achieve an opening and closing process. The closing process is forced after the current supplied to the solenoid valve is activated at the activation time, and the opening process is forced after the current supplied to the solenoid valve is deactivated at the deactivation time. The current is applied with a charging current strength prior to the activation time for the duration of a charging phase, and after the activation time, the current is increased to peak current strength and subsequently reduced to a holding current strength. Furthermore, after the deactivation time, the current strength is reduced to a deactivation current strength, and after a delay, the current strength (I) increases again as a result of induction. A variation of the value and/or duration of the current strength and/or an application of an additional magnetic force is used to simulate a premature activation, a delayed activation, a premature deactivation, and/or a delayed deactivation. 1.

Pressure reducer-regulator for feeding internal combustion engines with methane or other similar fuels

Номер: US20140109859A1
Автор: Luciano Cippitani
Принадлежит: Icomet SpA

The object of the present invention is a methane pressure reducer/regulator for feeding internal combustion engines which comprises a body divided into three chambers, communicating with each other by means of high resistance conduits and by means of an opening/closing element which is integral with an elastic diaphragm, whose surface is proportionally larger than the opening/closing element so that a modest pressure in the chamber upstream from the elastic diaphragm is sufficient to bend it, overcoming both the methane pressure resistance in the adjacent chamber, and the methane pressure resistance in the chamber directly connected to the tank(s), as well as the counter spring resistance. When the elastic diaphragm bends, it pushes a stem whose end is integral with the opening/closing element that allows or prevents the methane passage through a hole connecting the chamber from which methane is sent to the engine to the chamber wherein methane comes directly from the tank(s). Further, a conduit connects the chamber where a sufficient pressure is reached to bend the diaphragm, to the chamber from which low pressure methane is sent to the feeding system of the engine; according to a configuration, said conduit is provided with an on-off valve and a throat, or, alternatively, only with the on-off valve. The pressure regulator/reducer is completed by a pressure sensor, a pressure control valve, valves and connections to electronics which controls the engine feeding operation.
