Definitions
- the invention relates to the field of vehicle engines. It relates more specifically to the detection of failure of the gasoline vapor filter circuit ("canister" in English language) that equips vehicles with a gasoline internal combustion engine.
- the fuel tanks of these vehicles are equipped with a vapor recovery device.
- gasoline which reinjects them into the engine.
- This device usually called canister by the skilled person, is arranged near the fuel tank. It includes a carbon filter that fixes the gasoline vapors, especially when the engine is stopped.
- the injection of the vapors into the engine via the intake pipe is controlled by the engine control electronics ("ECU") allowing the opening and closing of a purge valve.
- ECU engine control electronics
- the present invention therefore aims to provide a device that meets the problem outlined above.
- a second object of the invention is to be simple and inexpensive to implement.
- the invention is directed to a method for detecting a fuel vapor filter purge valve blocking device for a hybrid engine vehicle comprising at least one internal combustion engine and an electric engine / generator.
- the method comprises a step of controlling the electric motor driving the internal combustion engine so as to maintain said internal combustion engine in a constant regime, during a start-up or pre-stop phase, and at least one sequence of following steps during this maintenance of the constant speed of the internal combustion engine:
- a step of measuring at least one operating parameter of the electric motor is a step of measuring at least one operating parameter of the electric motor
- the method comprises a repetition of the steps as described above, so as to obtain a statistically significant measurement.
- the operating parameter of the electric motor / generator is a torque value
- the internal combustion engine is driven without injection during the maintenance control stage of the internal combustion engine in a constant, non-idling mode.
- the invention aims, in a second aspect, at a device for detecting a gas vapor filter purge valve blocking device for a vehicle internal combustion engine, said device comprising:
- Means for measuring at least one operating parameter of the electric motor / generator
- the means for measuring at least one parameter of Engine operation / electrical generator include a motor / electric generator torque sensor.
- the invention finds its place in a land vehicle such as a car, hybrid type of motorization.
- the vehicle not shown in FIG. 1, comprises an internal combustion engine 1 powered by fuel contained in a fuel tank 2.
- the internal combustion engine 1 comprises an air intake manifold 5 and a fuel pipe. fuel supply 12, connected to the fuel tank 2.
- purge valve 4 is adapted to put into communication on command the vapor filter 3 and the air intake manifold 5 of the internal combustion engine 1, so as to partially recycle at least the fuel vapors contained in the filter with vapor 3.
- the vapor filter 3 is also in communication with an air intake 6 via a vent and a vent valve 7 (known under the term NVLD of the English "Natural Vacuum Leak Detector") capable of placing the vapor filter 3 in communication with the air intake 6.
- the vent valve 7 opens when the pressure in the vapor filter 3 exceeds a certain threshold or falls below a certain threshold. This is the case, for example, when the purge valve 4 is open and the internal combustion engine 1 is operating.
- the vacuum then created in the air intake manifold 5 sucks the fuel vapors contained in the vapor filter 3 and causes the opening of the vent valve 7. Air then passes through the filter at vapors 3 and is charged with fuel vapor before entering the air intake manifold 5.
- the vent valve 7 further comprises a pressure switch 8 adapted to switch a signal according to the level of depression in the vapor filter 3.
- the pressure switch 8 delivers its signal via a line 9 to a control electronics 10 which can be dedicated to system or shared with other vehicle components such as the internal combustion engine 1.
- the control electronics 10 is able to control the opening and closing of the purge valve 4 by a control line 1 January.
- the vehicle is of the hybrid type and also comprises an electric motor / generator (not shown in FIG. Figure 1), capable of driving the internal combustion engine 1.
- the method of detecting the operation of the purge valve 4 comprises several steps.
- control electronics 10 drives the electric motor / generator to drive the internal combustion engine 1 at a constant speed for a period of a few seconds (typically one to three seconds) during a start-up phase. or stopping said internal combustion engine 1.
- the internal combustion engine 1 is driven by the engine / electric generator without fuel injection into the cylinders (thus without combustion).
- the bleed valve 4 opens automatically. It closes when the pressure drops below a predetermined threshold.
- control electronics 10 controls the butterfly valve 13 controlling the quantity of air at the intake, according to a control profile adapted to keep constant, in theory, the flow flowing in the cylinders.
- control electronics 10 receives certain parameters measured at the level of the electric motor / generator, for example the electric power delivered and / or the couple etc. These parameters are measured by devices of a type known to those skilled in the art and are representative of the torque delivered by the internal combustion engine.
- control electronics 10 controls one or more cycles of opening and closing of the purge valve 4, and records the measured parameters.
- the internal combustion engine 1 behaves like a compressor.
- the torque produced by the motor / electric generator to maintain constant the speed of the internal combustion engine then depends directly on the injected air mass circulating in said engine.
- the purge valve 4 is blocked (in open or closed position). In this case, the flow of air from the gasoline vapor filter remains substantially constant, whereas the control electronics 10 anticipates a non-constant flow, and corrects the admission into the cylinders to maintain the constant global flow.
- the control electronics 10 Since the flow of air flowing in the internal combustion engine is not constant, the torque or electrical power or any other measured parameter representative of the torque at the level of the motor / electric generator is not constant.
- the control electronics 10 then records parameters whose variation over time is greater than a predetermined threshold, which then characterizes a malfunction of the purge valve 4. 21 Either the purge valve 4 operates properly. In this case, the flow in the cylinders is effectively constant.
- the control electronics 10 does not detect any significant variation in the measured parameter (s).
- the electric motor / generator of a hybrid drive vehicle being usually provided with engine torque sensors and / or measurements of the electric power delivered, etc.
- the detection of operation can be performed during a stopping phase of the engine, extended by a few seconds, which does not affect the performance of the car while driving.
- the internal combustion engine 1 is driven by the electric motor / generator, it is possible to obtain a particularly stable operating point (flow control circulating in the cylinders), which results in very good accuracy. diagnosis of the operation of the purge valve 4, the variability of the measured parameters being low, excluding the effect of a failure of the purge valve 4.
- the internal combustion engine 1 is driven by the electric motor / generator, maintaining the injection so as to reduce the effort required to the electric generator motor. The process however remains mainly unchanged.
