Definitions

  • the present invention relates to an additive supply system intended to be deposited on a particulate filter integrated in an exhaust line of a diesel engine of a motor vehicle.
  • additives are in fact intended to be deposited within the soot bed retained on the particulate filter, to lower the combustion temperature of them.
  • This additive in association with a particular engine operation, makes it possible to facilitate the regeneration of the particulate filter, in particular in duration.
  • motors of this type are associated with means of control of their operation which triggers during a regeneration phase of the filter, injecting fuel into the engine cylinders during their expansion phase to increase the temperature of the exhaust gases.
  • the additive is contained in a specific tank associated with the fuel tank via a system of pumping / dosing, which injects a determined quantity into the fuel tank additive depending on the amount of fuel added to the tank during a filling operation thereof for example.
  • this structure has a number of drawbacks, especially in terms of the complexity of such a pumping / metering system, its size, cost and the fact that certain fuels are incompatible with this additive.
  • the object of the invention is therefore to solve these problems.
  • the subject of the invention is a system for supplying an additive. intended to be deposited on a particulate filter integrated in an exhaust line of a diesel engine of a motor vehicle, to lower the temperature of combustion of soot trapped therein, characterized in that the additive is mixed with the engine lubricating oil when the oil is introduced into the engine.
  • FIG. 1 has indeed illustrated a block diagram illustrating the structure and operation of a system for adding an additive to the state of technical.
  • a fuel tank designated by the general reference 1 a vehicle diesel engine designated by the general reference 2, possibly associated with a turbocharger designated by the reference general 3, placed in an exhaust line 4 of it, this line exhaust also comprising for example an oxidation catalyst 5 and a particle filter 6.
  • a temperature sensor 7 can also be associated with this line, as well as a differential pressure measurement system at the terminals of the catalyst and the particulate filter, this system being designated by the reference general 8. These different means are linked to means of controlling the operation of the engine to trigger for example a regeneration phase of the filter.
  • the lower part of the engine 2 forms an oil reservoir lubrication thereof, designated by the general reference 9 and an oil filter 10 is also associated with this engine.
  • the additive intended to be deposited on the filter particles to lower the combustion temperature of soot trapped in this is contained in an additive tank designated by the general reference 11, associated with the fuel tank 1 via a pumping / metering system designated by the general reference 12.
  • FIG. 2 Illustrated in Figure 2, in the form of a block diagram, a exemplary embodiment of a supply system according to the invention.
  • the fuel tank is no longer associated with a specific additive tank through a pumping / metering system.
  • the additive is mixed with the lubricating oil of the motor.
  • the additive can be mixed with the oil before its introduction into the engine.
  • a specific oil already containing the additive is then developed and introduced into the engine, during the first filling of this or during each oil change.
  • a specific oil filler neck for this engine can then be used, this chute having a keying system to avoid that a conventional oil can be used.
  • Another solution consists in associating with the lubrication oil circuit engine, an additive tank associated with a pumping / metering system allowing during the first oil filling or during each oil change, introduce in the lubricating oil, a determined quantity of additive.
  • yet another solution may be to use an oil filter specific with an integrated additive tank.
  • This oil filter 10 then comprises an additive reservoir presenting itself for example in the form of an additive capsule designated by the general reference 13 containing a predetermined quantity of additive intended to be mixed with oil during the first filling or each oil change.
  • means for indicating the oil level of the engine may be used to deliver to the engine operating control means, information relating to the fact that an emptying has been carried out, in order to impose a change of the used oil filter and its replacement by a filter new containing additive.
  • a strategy for operating the engine in degraded mode can also be implemented by the operating control means of the engine in order to oblige the maintenance of the vehicle and to impose the changing the oil filter.
  • oil is consumed through the seal segmentation with respect to the walls of the engine cylinders, so that oil is burnt in the combustion chamber, through the bearing turbocharger lubrication, in which case oil is also burnt in hot exhaust gases or on the catalyst and through the guides intake valves, in which case oil is also burnt in the engine combustion chamber.
  • the additive content of the lubricating oil is then fixed to keep account of average engine fuel consumption and consumption in lubricating oil thereof, to achieve the same rate of additive brought by the oil in the particulate filter, than the one brought by the system conventional contribution of the state of the art, via fuel.
  • such an additive used can be cerine and an additive lubricating oil from an engine consuming an average of 0.1 liters of oil on 1000 kms and 7 liters of fuel per 100 kms added to a few ppm of additive by mass, is of the order of percent of cerine by mass or any other compound making it possible to maintain the same combustion kinetics soot trapped in the internal structure of the particulate filter.
  • the filter element of the oil filter can also be soaked in additive to ensure mixing with the oil, as shown in figure 4.
  • This filter element is in fact generally formed of a cardboard material porous whose properties allow it to adsorb the additive and restore it when introducing and circulating oil in the engine.
  • this oil filter and additive assembly can also be designed to be placed in the engine oil pan and carried by the plug engine oil drain as shown in figure 5.
  • the engine oil pan is designated by the reference 15 and the oil filter with the general reference 10, including the filter element 14 is soaked with additive.
  • This filter is then carried by an oil drain plug 16 fixed to the rest of the engine by any suitable means allowing for example prohibit the reassembly of a used filter after disassembly.
  • the additive is contained in a capsule 17 carried by the drain plug 16, so as to be engaged in the oil pan 15 of the engine.
  • the fixing of the plug on this casing is carried out using means prohibiting the reassembly of a used capsule after disassembly. This ensures that the vehicle maintenance operator change the capsule well at each drain, the capsule is then adapted to release the additive to allow mixing with the oil.
  • the capsule can be made of thermally dilutable material in the oil so that when the engine oil heats up during operation from it, the additive can be released.
