Patent application number | Description | Published |
20090205316 | System and processes for storing an additive and injecting it into the exhaust gases of an engine - System for storing an additive solution and injecting it into the exhaust gases of an internal combustion engine, the system comprising a tank for storing the additive and a rotary pump, a metering valve and an injector which are separate devices, this system making it possible to meter and inject the additive solution into the exhaust gases as is, without diluting it with a gas. In this system, the pump outlet pressure is regulated by adjusting the rotational speed of the pump. | 08-20-2009 |
20090205319 | Ammonia Precursor Storage System - A system for storing an ammonia precursor, comprising a tank, a filler pipe equipped With an obturator and a ventilation line establishing a direct connection between the filler pipe and a gas discharge duct and also a device designed to specifically open this connection once the obturator starts to be opened. | 08-20-2009 |
20090230136 | ENGINE EXHAUST GAS ADDITIVE STORAGE SYSTEM - System for storing an internal combustion engine exhaust gas liquid additive, the system comprising a tank for storing the additive and an “immersed” baseplate positioned through an opening made in the bottom wall of the tank, the baseplate comprising at least one orifice through which a system for injecting the additive into the exhaust gases can be fed, and also incorporating at least one other active component of the storage system and/or of the injection system. | 09-17-2009 |
20100186374 | Method for Heating an SCR System using Resistive Heating Elements - Method for heating a urea SCR system using at least two resistive heating elements (R | 07-29-2010 |
20100199648 | System for storing an additive solution and injecting it into the exhaust gases of an engine - System for storing an additive solution and injecting it into the exhaust gases of an engine, said system comprising two tanks for storing the solution and one pump for supplying the solution from these tanks to an injection line, these two tanks being in parallel and each being connected to the pump by a branch of a supply line, the branch (I) coming from the first tank ( | 08-12-2010 |
20100220984 | Urea tank and base plate with an integrated heating element - Urea tank and base plate with an integrated heating element in which the heating element comprises at least one flexible part which is preferably a flexible heater comprising at least one resistive track affixed to one flexible film and/or placed between two flexible films. | 09-02-2010 |
20140093226 | UREA TANK AND BASE PLATE WITH AN INTEGRATED HEATING ELEMENT - Urea tank and base plate with an integrated heating element in which the heating element comprising at least one resistive track affixed to one flexible film and/or placed between two flexible films. | 04-03-2014 |
20140284224 | TANK FOR STORING AMMONIA BY SORPTION - A tank for storing ammonia by sorption, the tank including cells, or cells made of plastic, that communicate with one another and with at least one orifice that communicates with the outside, the cells configured to contain a solid intended for the sorption of ammonia. | 09-25-2014 |
20140345258 | ENGINE EXHAUST GAS ADDITIVE STORAGE SYSTEM - System for storing an internal combustion engine exhaust gas liquid additive, the said system comprising a tank for storing the additive and an “immersed” baseplate ( | 11-27-2014 |
