Definitions

  • the present invention relates to a device fuel injection from an internal combustion engine, in particular with common rail for Diesel engine.
  • the invention aims to provide a device injection without the drawbacks presented above.
  • the device injection can operate with a piloting of the benches distributed over the injectors so that the fuel supply to the injectors is adapted to the closer to emission reduction requirements polluting.
  • piloting the injectors that were there connected is automatically picked up by another bank command, which allows to keep at least temporarily engine performance to such a degree that safety remains preserved even when driving risk.
  • each injector, 3 to 6 is connected to an outlet of the same rank from each of the benches control via an inverting member, respectively 7 to 10.
  • the bench 1 controls the injectors 3 and 6 and bank 2, injectors 4 and 5.
  • the control benches 1 and 2 are connected to a measurement module 11 which records several parameters and which is connected to a monitoring module 12 responsible for detect malfunctions of the benches command 1 and 2.
  • This function can be executed according to strategies known per se for monitoring operating parameters of the benches. For example, we can control the voltage across some of their components or the intensities of the currents flowing there.
  • the monitoring module 12 provides failure signals respectively bank_fault_1 or default_bank_2 formed by Boolean values indicating, when they are true (value 1 for example) that a fault is present in the corresponding control bench. These signals are applied respectively to two blocks 13 and 14 with OR function, the outputs of which control the inverters 7, 10 or 8, 9 respectively.
  • the signals default_bank_1 and fault_bank_2 are also applied to a fault memory 15 which stores fault signals possibly during taxiing current vehicle, to be able to restore them at start-up next to his engine.
  • the inscription in this memory of default_bank_1 or default_bank_2 signals preferably occur during the shutdown phase of the CC control computer. So, as the case may be, during the next start of it, memory 15 makes a signal available default_bank_1_mem or a signal default_bank_2_mem, meaning that a fault has occurred during a previous one use of the engine, in one or other of the benches command 1 or 2.
  • the signals default_bank_1, default_bank_2, default_bank_1_mem and default_bank_2_mem are applied together with a block 16 with OR function whose output is connected to a fault signaling device 17. This last can be a light on the dashboard of the vehicle, shared or not with other signaling functions relating to other malfunctions of the vehicle.
  • the signals default_bank_1 and fault_bank_2 are also applied to a block 18 with OR function whose output is transmitted to a bank deactivation block 19 1 or 2 depending on whether one or the other of the signals correspondents is true.
  • the injection control device also includes means for, in the event of failure of control benches 1 or 2, limit the desire to accelerate the driver of the vehicle.
  • the output of the OR function block 18 is connected to a counter 20 which makes it possible, in the event of a fault with a bench of order, i.e. when default_bank_1 or default_bank_2 is 1, to total the time since the appearance of the fault.
  • This counter 20 provides a signal temps_def_banc and it is reset to zero after each reset the CC control computer.
  • the output of counter 20 is connected to a block of mapping 21 which depending on the position of the counter 20 allows you to select a value to which limits the driver's "willingness to accelerate” vehicle in the event of failure of one of the benches 1 or 2.
  • the corresponding value is called here “reduced value of maximum acceleration request ".
  • mapping block 21 The output of the mapping block 21 is applied to an inverter 22 which also receives a will_max signal which represents, for failure-free situations, a value maximum calibrated acceleration the driver can impose. This value is called here “demand value maximum acceleration ".
  • the inverter 22 is normally placed on the terminal at which is applied the will_max signal. However, he is inverted under the control of the block output at OR 18 function, i.e. in the event of detection of a failure.
  • the output of the inverter 22 is applied to a block 23 with an OR function which makes it possible to transmit, i.e. the value from inverter 22, i.e. that supplied by a another inverter 27 yet to be described.
  • the exit of the block at OR function 23 is connected to a first input of a block 24 says "minimum function" (MIN).
  • This block 24 also receives on another input a variable signal will_conductor generated, according to engine control system, from a parameter reflecting the current acceleration demand of the driver.
  • This parameter can be a voltage measured in depending on the position of the accelerator pedal, a requested torque value, quantity of fuel injected by injection, a percentage of charge or other.
  • the output signal vol_cond_lim of block 24 to MIN function is either the actual acceleration demand of the conductor, when this is less than the value from mapping block 21, i.e. the latter value when the actual demand for acceleration of the driver exceeds it.
  • This output signal is transmitted to the application software 25 of the CC computer responsible for managing the engine operation. This output signal thus translates driver's desire to accelerate while driving with failure but it cannot exceed the limit value imposed.
  • Software 25 also receives signals default_bank_1 and default_bank_2 from the module of monitoring 12 in order to adapt the operation of the engine to the default situation.
  • the signals default_bank_1 mem and fault_bank_2_men are applied to a block with OR function 26 whose output is applied to a second inverter 27.
  • This receives on one of its terminals a will_max_def_mem signal which fixes the maximum acceleration demand value in case of a driving after restarting the engine.
  • the other terminal of the inverter receives the will_max signal used during the fault-free operation.
  • the output of the inverter 27 is applied to block 23 with OR function for power, if applicable if necessary, be transmitted to block 24 with MIN function.
  • each of these test benches two injectors (3, 6 or 4.5, respectively), the inverters 7 to 10 being then in their position shown in the figure.
  • inverters 7 and 10 are tilted under the command of the signal default_bank_1 passing through the OR block 13.
  • injectors 3 and 6 are now also piloted by bank 2 which has not failed.
  • the driver is alerted by the signaling device 17, while bank 1 is deactivated via from block 19.
  • the signal will_max limits the driver's acceleration request at the maximum calibrated will_max value.
  • the inverter 22 switches under the control of the signal from the OR block 18. From this moment, the maximum acceleration demand value is governed by time function by the mapping deposited in the block 21.
  • This particular feature of the invention allows in particular to warn the driver of the vehicle through an unusual reaction on the behavior of the vehicle. For example, it is possible to report a failure of banks 1 or 2 by a drastic reduction (possibly up to zero), but brief value reduced maximum acceleration demand, driving thus to a total or almost total cut of the injection for a brief period of a few milliseconds per example. This will result in a very sudden rolling noticeable to the driver, without compromising security, for example during a overshoot.
  • the law of modification of the reduced value of maximum acceleration demand can also be chosen from so as not to start limiting the performance of the engine only after a sufficiently long time (10 seconds per example) so that the driver can bring the vehicle in good security conditions before any lapse engine performance.
  • the invention offers great flexibility to calibrate as a function of time the management of the degraded engine operation.
  • Performance limitation in the event of one failure control benches will also encourage the driver to quickly have your vehicle repaired and immediately adopt a prudent behavior so as to be able to overcome more easily any failure of the other control bench.
  • performance limitation is governed uniformly by the signal vol_max_def_mem on which switches the system under the control of one or the other of the signals default_bank_1_mem and default_bank_2_mem.
  • This characteristic of the invention presents the advantage, in addition to those already mentioned, of avoiding a return to normal vehicle performance which would in principle possible since the engine could run at full performance with a single control bench, but which would give the driver the impression that the failure would have missing and could lead to a situation dangerous, if the only non-faulty control bench also deteriorated.
