摘要:
A method for detecting whether an injector with a valve controlled by a PWM signal of an SCR system is at least partially clogged, the system including a pump, or a positive-displacement pump, driven by a motor and pressure of which is controlled by a controller that continuously measures the pressure and/or another parameter characteristic of energy transmitted by the motor to the pump. According to the method, during normal operation of the SCR system, specific portions of one of the measurements are compared with equivalent portions stored in a memory.

A reservoir for holding a quantity of fluid within a tank, the reservoir including a first resistive element for heating a first part of the tank and a second resistive element for heating a second part of the tank, the second resistive element having a positive temperature coefficient. The reservoir further includes a third resistive element for heating the second part of the tank, the second resistive element and the third resistive element forming a parallel circuit, and the first resistive element being connected in series with the parallel circuit.
摘要:
Noise reduction baffle for a fuel tank comprising a lower carrier and an upper sliding part which can slide relatively to the carrier thanks to compression springs mounted on retainers, said lower carrier having a hollow foot comprising two vertical or inclined walls defining an open cavity of elongated shape having a longitudinal axis, said cavity comprising at least one rib making an angle with the longitudinal axis of the cavity.
摘要:
A method and system for generating power on board a vehicle. The method includes: generating a gas by chemically decomposing an ammonia precursor in a biochemical decomposition unit mounted on board the vehicle and storing at least one protein component adapted to decompose the ammonia precursor; converting the gas into power in at least one power generator mounted on board the vehicle.
摘要:
A vehicle supply system including a reservoir for storing a fluid; and a supply circuit arranged for being in fluid communication with the reservoir. The supply circuit is such that it includes a thermo-hydraulic section configured for generating a temperature difference between a first portion and a second portion of the thermo-hydraulic section, the temperature difference being capable of causing evaporation in the first portion and of causing condensation in the second portion such that an oscillating flow is generated between the first portion and the second portion. The supply circuit is such that it is configured for using the oscillating flow for sucking fluid from the reservoir.
摘要:
A hollow body (1) comprises an accessory module (2) fastened to the wall (13) thereof by being inserted by sliding into a slide (12) formed in said wall. The module (2) comprises a housing (20) and two flat and flexible wings (23) that extend from the housing in opposite directions, the distant edges (24) of said wings extending substantially parallel and being inserted respectively into the opposite grooves (14) of the slide, and the module also comprises at least one flexible fin (25) that extends from the housing, said fin (25) being shaped so that it is bent elastically during the sliding insertion of the module (2) into the slide (12) and so that its end (26) is facing a stop member (151) of the slide when the fin is not bent and is situated beyond the end of said slide in the direction of sliding.
摘要:
An SCR method for purifying the exhaust gases of an internal combustion engine of a vehicle, according to which ammonia gas is exclusively metered in the exhaust gases, the method comprising a step of releasing ammonia gas from at least one solid absorbing matrix where it is stored by sorption and a step of metering the released ammonia gas in the exhaust gases. The method is such that it comprises a step of regenerating the solid absorbing matrix that consists in: generating a refilling ammonia gas by thermally decomposing an ammonia precursor in a heater mounted on board the vehicle; directing the refilling ammonia gas to the solid absorbing matrix where it is stored thereon.
摘要:
Method for manufacturing a storage tank comprising an inner liner, an outer filament winding and a connecting part. The method comprises the steps of: blow molding the inner liner by extruding a parison, pinching the inner liner at least at one extremity to create a pinch and then blowing the parison; providing the connecting part with a slot of appropriate shape and size to receive a part of the pinch; inserting the part of the pinch in the slot so as to secure the inner liner and the connecting part; and applying the outer filament winding around the liner and the connecting part.
摘要:
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 (1) positioned through an opening made in the bottom wall of the tank, the said baseplate comprising at least one orifice through which a system for injecting the said 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.
摘要:
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.
