20080202561 | Methods and Compositions for Reducing Deposits In Engines Combusting Alcohol-Containing Fuels - The present disclosure provides compositions and methods for reducing deposit formation in engines combusting a fuel containing ethanol and a corrosion inhibitor. The present disclosure also provides compositions and methods for reducing deposit formation in engines combusting a fuel containing ethanol, a corrosion inhibitor, and a dispersant. | 08-28-2008 |
20100319731 | METHOD AND APPARATUS FOR CLEANING PARTICLE FILTERS IN EXHAUST GAS SYSTEMS OF COMBUSTION ENGINES - 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 ( | 12-23-2010 |
20110308550 | METHODS RELATING TO FUEL COMPOSITIONS - A method of removing deposits from a diesel engine, the method comprising combusting in the engine a diesel fuel composition comprising an engine cleaning additive, wherein the engine cleaning additive is the product of a Mannich reaction between: (a) an aldehyde; (b) ammonia, hydrazine or an amine; and (c) an optionally substituted phenol; wherein the or each substituent of the phenol component (c) has an average molecular weight of less than 400. | 12-22-2011 |
20130000678 | METHOD AND SYSTEM FOR CONTAMINATION REMOVAL FROM A PARTICULATE MATTER SENSOR - A method and system is described for removing contamination from a conductive particulate matter sensor. The sensor has a substrate with two electrodes on the substrate configured to collect particulate matter between the electrodes, thereby establishing an electrically conductive path through collected particulate matter between the electrodes that can be detected by measuring electrical resistance between the electrodes. The method includes heating the sensor to a first temperature for a first duration of time, wherein the first temperature and first time are sufficient to remove collected particulate matter from the sensor. The method further includes heating the sensor to a second temperature for a second duration of time, wherein the second temperature is higher than the first temperature, to remove contaminants that cannot be removed by heating to the first temperature for the first duration of time. | 01-03-2013 |
20130098404 | ENGINE CLEANING METHOD - A method to remove carbonaceous deposits from the internal surfaces of ignition compression engines by increasing inlet air temperature to 60-200° C. and injection of polyol instead of operational fuel for 1-30 minutes. | 04-25-2013 |
20140261555 | DE-CARBONIZING PROCESS FOR COMBUSTION COMPONENT CLEANING - A cleaning composition and process to remove carbon deposits from combustion equipment components is provided. The de-carbonizing composition is packaged in certain embodiments in an aerosol propellant. The inventive composition is also readily used as a liquid or an atomized mist that is readily introduced into the intake manifold through a tube tolerant of engine inlet operational temperatures and conditions. The invention introduces the composition by a process that precludes the need for engine disassembly. | 09-18-2014 |
20160102253 | DELAYED COKER FEED HEATER ON-LINE STEAM-CHEMICAL DECOKING METHOD - A process for decoking of delayed coker feed heater pass is disclosed. A chemical mixture containing a metal hydroxide and a metal carbonate is combined with steam to decoke the delayed coker feed heater pass. | 04-14-2016 |
