Definitions
- the invention relates to internal combustion engines with spark ignition, and in particular the control of ignition advance values of such engines.
- the ignition advance is the difference between the moment the spark is triggered and the moment the piston reaches its TDC. This advance is generally quantified in terms of angle that forms the rod relative to the axis of the piston at the moment of the spark.
- the determination of the most favorable ignition advance makes it possible to obtain the best torque and / or engine efficiency.
- the engine control computer is thus in charge of calculating advance orders as a function of different operating parameters of the engine.
- the feed is usually dynamically changed during engine operation. The faster the engine runs, the more you have to increase the lead. In the event of a high load on the engine, the advance must be reduced.
- the transition from the application of a first ignition advance setpoint to a second ignition advance setpoint is done by applying forward values to the ignition.
- intermediate ignition between the first and second values.
- the intermediate ignition timing values applied after predetermined intervals of the number of motor cycles are incremented.
- the transient operating phase between the first and second ignition advance setpoints induces despite any deterioration of the approval of use of the engine, especially at high engine speed variations.
- the user can indeed feel jolts of torque variation during the transient phase in case of strong variations in regime.
- the invention aims to solve one or more of these disadvantages.
- the invention thus relates to a method for controlling the controlled ignition of an internal combustion engine, comprising the steps of:
- the increment between two successive intermediate values being defined according to the instantaneous engine speed, such that the increment increases if the engine speed decreases.
- the duration of application of an intermediate advance value is defined as a function of the instantaneous engine speed so that the duration of application increases if the instantaneous engine speed decreases.
- the ratio between the durations of application of the intermediate values in advance and the corresponding increment of the progression is constant.
- the invention also relates to a computer for controlling the ignition in a spark ignition engine, comprising an interface for receiving an instantaneous engine speed value, and configured for:
- the computer is configured to apply ignition control signals with respective forward intermediate values for a defined duration of application as a function of the instantaneous engine speed so that the duration of application increases. if the instantaneous engine speed decreases.
- the computer is configured to generate control signals with intermediate values in advance so that the ratio between the periods of application of the intermediate values in advance and the corresponding increment of the progression. is constant.
- Figure 1 is a schematic representation of the ignition control of a spark ignition internal combustion engine
- FIG. 2 is a diagram illustrating the calculations carried out according to an exemplary control method according to the invention.
- FIG. 3 is a comparative diagram of the evolution of the ignition advance for an exemplary implementation of the invention and for an example according to the state of the art respectively;
- Figure 4 illustrates the variation of the engine speed resulting in the diagram of Figure 3.
- Figure 1 is a schematic sectional view of an internal combustion engine 1 at a cylinder.
- the engine 1 is a spark ignition engine.
- the engine 1 can typically be mounted in a motor vehicle.
- the engine 1 is provided with a motor control computer 2.
- the engine control computer 2 controls a number of components of the engine 1 not shown (for example fuel injectors, a valve air intake, an exhaust gas recirculation valve, etc.) to define the operating parameters of this engine 1, according to different measured values and according to different maps.
- the engine control computer 2 also records a number of operating parameters of the engine 1, such as the exhaust gas temperature, an ambient temperature, a motor rotation speed or an instantaneous torque of the engine.
- a piston 13 is slidably mounted in a combustion chamber 14.
- An intake valve 1 1 is controlled by a camshaft for selectively communicating an intake duct with the combustion chamber 14.
- Exhaust 12 is controlled by a cam shaft for selectively communicating an exhaust line with the combustion chamber 14.
- An injector (not shown) is configured to provide fuel injections directly or indirectly into the combustion chamber 14 .
- a spark plug 15 is controlled by the computer 2 to generate a spark in the combustion chamber at a suitable time.
- the computer 2 controls the generation of the spark with a spark advance (generally defined in degrees of rotation angle of the crankshaft relative to the top dead center) adapted to the operating conditions of the engine.
- the computer 2 is capable, in a manner known per se, of assigning different setpoint values for the ignition advance during the operation of the engine 1.
- the invention proposes a control method for performing a transition between a first ignition advance setpoint and a second ignition advance setpoint. Initially, ignition of the engine 1 is carried out with the first advance setpoint value. The computer 2 then determines a second advance setpoint value to be applied.
- the controlled ignition is carried out with intermediate intermediate values between the first and second advance set point values.
- the intermediate values of the ignition advance are set according to a progression by applying increments between the successive values. If the first setpoint value is lower than the second setpoint value, the intermediate values are increasing. If the first setpoint is greater than the second setpoint, the intermediate values are decreasing.
- the value of an increment is set according to the instantaneous engine speed, so that the increment increases if the instantaneous engine speed decreases.
- the duration of application of an intermediate advance value is advantageously defined according to the instantaneous engine speed, so that the duration of application increases if the instantaneous engine speed decreases.
- the ratio between the increment of advance separating two successive intermediate advance values of the progression and the corresponding duration of application is advantageously constant.
- the ignition advance varies linearly between the two advance setpoint values.
- Rii / Dai ratios are all equal to a constant Kp (Dai being a duration of application of an intermediate index advance value of index i, Rii being an index advance step of index i).
- FIG. 2 is a diagram illustrating the calculations carried out according to an exemplary control method according to the invention.
- the computer 2 retrieves the value Ni of the instantaneous engine speed.
- a module 22 recovers the value Dai and the constant Kp.
- the module 23 applies the increment Rii to the previous intermediate value of advance, to generate the new intermediate value Sai advance.
- the advance synchronization signals can be triggered by a passage of the engine by the top dead center of combustion, so be based on the duration of an engine cycle or the duration of a crankshaft revolution.
- the set values may for example include a maximum advance value ensuring the absence of knocking and a minimum value ensuring the achievement of a combustion.
- the different advance setpoint values are applied depending on the operating conditions of the engine, for example to perform a temporary regeneration of a depollution device, when stopping the actuation of the accelerator.
- FIG. 3 is a comparative diagram of the evolution of the ignition advance over time, during the transition from a first ignition advance setpoint C1 to a second advance setpoint at C2 ignition.
- the curve in solid line corresponds to the evolution of the ignition advance during the implementation of the invention.
- the curve in dashed line corresponds to the evolution of the ignition advance according to a method of the state of the art.
- FIG. 4 represents the evolution of the engine speed in time, during the transition from the advance setpoint to ignition C1 to the ignition advance setpoint C2. The engine speed thus drops strongly to idle speed before going up quite strongly.
- the evolution of the ignition advance with a method according to the invention is very linear, which avoids an unpleasant feeling of torque variation.
- the regulation of other engine operating parameters is also facilitated.
- the engine consumption and its pollutant emissions can be optimized.
