- Patent Document 1 As a method of optimizing an ignition timing in a spark ignition type internal combustion engine, a method of determining an ignition timing based on a negative ion current in a cylinder is known (for example, see Patent Document 1).
- the negative ion current flowing in the cylinder immediately after ignition is measured, and the time from ignition at the point where the current value of the negative ion current becomes maximum is measured. Then, the time difference between the measured time and the position of MBT (Minimum spark advance for Best Torque) is calculated, and the calculated time difference is added to or subtracted from the previous ignition timing. Determine the ignition timing.
- MBT Minimum spark advance for Best Torque
- Patent Document 1 JP-A-6-33855
- the ignition timing can be adjusted to MBT by adjusting the ignition timing so that the peak position of the negative ion current is 15 degrees after the top dead center.
- the position of the combustion pressure peak varies depending on the operating state. Therefore, the above 2) is an assumption that the force does not hold in a certain limited operating region. That is, for example, at the time of MBT when the burning speed is decreasing, the peak position of the ion current is not 15 degrees after the top dead center. Therefore, in the above control, the ignition timing could not be adapted to the MBT.
- the present invention has been made in view of the above-mentioned conventional problems, and it is possible to execute control such as, for example, adapting the ignition timing to the MBT without measuring the torque and the combustion pressure. It is an object of the present invention to provide a device or a method capable of improving fuel efficiency, reducing exhaust gas, improving driver's utility, and the like.
- An engine operation control device includes an ion current measurement device that measures a negative ion current in a combustion chamber of an engine, a crank angle measurement device that measures an engine crank angle, and a negative ion current with respect to the crank angle.
- the engine is operated based on a first crank angle at which the rate of increase becomes equal to or more than a first predetermined value and a second crank angle at which the rate of increase becomes equal to or less than a second predetermined value after the rate of increase becomes equal to or more than the first predetermined value.
- a control device for controlling for controlling.
- the step of measuring a negative ion current in the combustion chamber of the engine includes the step of: (1) detecting a crank angle; detecting a second crank angle at which the increase rate becomes equal to or less than the first predetermined value and then becomes equal to or less than a second predetermined value; Calculating the combustion center of gravity from the crank angle.
- the step of measuring the negative ion current in the combustion chamber of the engine includes the steps of: (a) increasing the negative ion current with respect to the crank angle of the engine to a first predetermined value or more; Detecting a crank angle; detecting a second crank angle at which the rate of increase becomes equal to or less than a second predetermined value after the increase rate becomes equal to or more than the first predetermined value; and the first crank angle and the second crank angle Controlling the engine on the basis of the above.
- the control of the engine is executed or the combustion center of gravity is calculated based on the rising point and the peak point of the negative ion current in the characteristic curve of the negative ion current. Therefore, unlike the case where the above control or calculation is performed based only on the peak point of the negative ion current, when the peak point moves due to a change in the operating state, etc. Even so, accurate control or calculation can be performed. Therefore, control such as adapting the ignition timing to the MBT can be realized over a wide operating range without measuring the torque and combustion pressure.

- the air intake 104 and the air cleaner 105 are connected via an intake duct 107.
- the air cleaner 105 and the engine 1 are connected via an intake pipe 108.

- a recess 4a is formed on the mating surface of the cylinder head 4 on the cylinder block 3 side.
- the combustion chamber 5 is defined by the concave portion 4a, the piston 6, and the cylinder bore 3a.
- the cylinder head 4 is provided with an intake valve opening 4b and an exhaust valve opening 4c that open into the recess 4a.
- the cylinder head 4 is provided with an intake valve 9 and an exhaust valve 10 for opening and closing the intake valve opening 4b and the exhaust valve opening 4c, respectively.
- the intake valve 9 and the exhaust valve 10 are driven to open and close by an intake cam shaft 11 and an exhaust cam shaft 12, respectively.
- a variable valve timing mechanism 13 is connected to the intake camshaft 11 and the exhaust camshaft 12.
- the variable valve timing mechanism 13 receives a knob timing control signal a from an engine control unit (hereinafter referred to as ECU) 16 and adjusts the opening / closing timing of the intake valve 9 and the exhaust valve 10 by the intake camshaft 11 and the exhaust camshaft 12.
- ECU engine control unit
- An ignition plug 14 is inserted into the cylinder head 4.
- the ignition plug 14 is disposed substantially at the center of the recess 4a, and the electrode of the ignition plug 14 is exposed near the inner surface of the recess 4a.
- An ignition device 15 is connected to the ignition plug 14.
- the ignition device 15 receives the ignition timing control signal b from the ECU 16 and controls the spark generation timing by the ignition plug 14.
- the ignition plug 14 is also used as a negative ion current probe.
- a positive electrode 17a of a battery 17 is connected to the spark plug 14, and a negative electrode 17b of the battery 17 is connected to the cylinder head 4 via an ammeter 18 and grounded.

- the engine 1 is provided with a crank angle detection sensor 19 and a knock detection sensor 20 for detecting knocking. Detection signals from the crank angle detection sensor 19 and the knock detection sensor 20 are input to the ECU 16. As described later, when knocking is detected by knock detection sensor 20, ignition timing control by ECU 16 is restricted.
- the negative ion current generated in the combustion chamber 5 changes with the progress of combustion. That is, when the ignition plug 14 ignites the air-fuel mixture in the combustion chamber 5, the first scientific action is activated, and electron energy in atoms or molecules receives energy by collision of these electrons. Then, the atom or molecule is in an excited state with sufficient heat generation to move to an energy state higher than the normal stable state. Along with the transition to the excited state, chemiluminescence centering on ultraviolet rays occurs, and positive ions increase. As a result, the negative ion current in the combustion chamber 5 increases accordingly. This negative ion current is captured by the ignition plug 14 also used as the ion current probe, and is input to the detection value power 3 ⁇ 4CU 16 of the ammeter 18.
- FIG. 3 shows characteristic curves of the negative ion current E and the combustion pressure P with respect to the crank angle.
- the characteristics of the negative ion current E show almost the same tendency as the characteristics of the combustion pressure P. Therefore, the negative ion current E can be used as information indicating a change in the combustion pressure P and thus the flame area or heat generation.
- the crank angle at which the combustion pressure P becomes maximum varies depending on the operating state of the engine 1. Therefore, the peak position of the characteristic curve of the negative ion current E changes according to the operating state of the engine 1 (see FIG. 4.
- FIG. 4 is only a conceptual diagram for explanation, and is based on actual measurement data. Not something). Therefore, control based only on the peak position of the characteristic curve of the negative ion current E cannot flexibly cope with fluctuations in the engine load, etc., and cannot be applied in a wide range of operating conditions. .
- FIG. 5 (b) shows the change of the negative ion current E with respect to the crank angle
- FIG. 5 (a) shows the change of the heat release rate D and the combustion mass ratio F with respect to the crank angle.

- the rate of increase of the ion current with respect to the crank angle is smaller than a predetermined value (hereinafter, referred to as a first predetermined value). That is all.
- a predetermined value hereinafter, referred to as a first predetermined value.
- the rate of increase becomes equal to or more than the first predetermined value, and thereafter becomes a predetermined value (hereinafter, referred to as a second predetermined value.
- the second predetermined value is different from the first predetermined value. (May be equal to the first predetermined value).
- a point where the increase rate is equal to or more than the first predetermined value can be referred to as a rising point
- a point where the increase rate becomes equal to or more than the first predetermined value and then equal to or less than the second predetermined value can be referred to as a peak point.
- the actual method of specifying the rising point or the peak point is not limited at all. When specifying the rising point or the peak point, it is not always necessary to calculate the increase rate.For example, the rising point or the peak point is determined by comparing the magnitude of the detected value of the ion current with a predetermined threshold value. It is also possible to specify.
- the first crank angle B is set to a crank angle corresponding to a rising point of the ion current curve
- the second crank angle C is set to a crank angle corresponding to a peak point of the ion current curve.
- the first crank angle B and the second crank angle C may not be exactly the same as the rising point and the peak point, respectively.
- the point force may be slightly shifted. That is, the first crank angle B and the second crank angle C may be points that can be substantially regarded as the rising point and the peak point, respectively.
- the point of occurrence of the negative ion current (position corresponding to the first crank angle B), which is considered to be the initial stage of the combustion, is determined by the ignition delay period after the discharge of the spark plug 14. It is considered that this is the point where heat generation starts when the initial combustion starts.
- the subsequent peak position (the position corresponding to the second crank angle C) is considered to be the point where the heat generation during combustion becomes maximum. Therefore, the intermediate position between these points is estimated to correspond to the center of gravity of combustion.
- a substantially intermediate point between the first crank angle B and the second crank angle C can be regarded as a crank angle (hereinafter, referred to as a third crank angle) G corresponding to the center of gravity of combustion. Therefore, the combustion center of gravity can be calculated based on the first crank angle B and the second crank angle C. And, as will be described later, when the ignition timing is MBT, the center of gravity of combustion does not change significantly even if there is a change in load or the like. Therefore, in the present embodiment, the ECU 16 presets a predetermined crank angle corresponding to the center of gravity of combustion at the time of MBT as a target crank angle, and determines the third crank angle obtained from the measurement of the negative ion current as the target crank angle.
- the ignition timing of the ignition device 15 is controlled so as to match the angle.
- the value of the target crank angle is set so as not to be changed by the load condition of the engine 1, because the center of gravity of combustion does not greatly change due to load fluctuation or the like. You may.
- the value of the target crank angle may be a constant value.
- the value of the target crank angle may be a value that is changed by an individual difference or aging of the engine 1 or the like, and may be appropriately changed based on an arithmetic expression including a parameter or a table.
- FIG. 6 shows the relationship between the engine speed, the ignition timing, the center of gravity of combustion, and the like.
- the combustion center of gravity is calculated based on the first crank angle B and the second crank angle C.
- the first crank angle B, the second crank angle C, and the third crank angle G are respectively represented as “ignition angle”, “combustion end”, and “combustion center of gravity”.
- the section A-B represents the ignition delay section
- the section B-C represents the combustion section.
- the target crank angle corresponding to the combustion center of gravity is set to be about 115 degrees before top dead center. Then, the ignition timing is feedback-controlled so that the third crank angle G becomes the target crank angle (115 degrees before the top dead center).
- FIG. 7 shows the relationship between ignition timing, torque, combustion center of gravity, and the like.
- the torque changes depending on the ignition timing, and becomes maximum when the ignition timing is MBT.
- the center of combustion shifts from the position after the top dead center to the position before the top dead center. Therefore, the torque increases as the combustion center shifts from the position after top dead center to the position before top dead center, and becomes maximum when the combustion center is about 2 to 3 degrees before top dead center. Furthermore, it decreases as it shifts to the position before the top dead center.
- the ignition timing is controlled so that the third crank angle G (the crank angle corresponding to the center of gravity of combustion) is 2 to 3 degrees before the top dead center, so that the ignition timing can be adjusted before the top dead center. — 36 degrees, indicating that the ignition timing complies with MBT.
- the target value of the third crank angle G does not significantly change due to fluctuations in the operating state. For this reason, for example, when the lift amount and opening / closing timing of the intake valve 9 are variably controlled in a complicated manner, or when it is desired to simply change the engine load conditions such as the rotational speed and the throttle opening, the negative ion current in the combustion chamber 5 is also required.
- the ignition timing to the MBT easily by measuring the It becomes possible.
- the load conditions were changed, and the third crank angle G was measured. Specifically, the load conditions were changed by changing the throttle opening or the rotation speed. Then, when the third crank angle (an angle between the first crank angle B and the second crank angle C) G during MBT was measured, the rising point and the peak point of the negative ion current curve varied in various ways. Force Under all load conditions, the third crank angle G was 1 degree before top dead center. That is, it has been found that, in the internal combustion engine, the third crank angle G at which the ignition timing becomes MBT is the same under all load conditions. For example, comparing FIGS. 7 and 8 showing torque characteristics and the like when the load conditions are different, the third crank angle G when the ignition timing conforms to MBT is about 1% before the top dead center. It's a degree.
- the combustion mass ratio has been pseudo-converted from the combustion pressure, and the heat generation has been predicted and converted based on the combustion mass ratio.
- the heat generation distribution at ⁇ is considered to be a distribution in which about 30% of the total is located before top dead center and about 70% is located after top dead center. , The center of combustion was considered to be located after top dead center.
- the combustion center of gravity is near top dead center, more specifically, 115 degrees before top dead center. This difference is presumed to be due to the following reasons. In other words, most of the negative ions during combustion are in the excited state of cold and blue flames. Occurs. However, the heat generation determined from the combustion pressure is generated as a result of light emission of amplitude transition, such as a flame reaction after a cold flame and a blue flame, that is, a solid-state radiation centered on infrared rays. Therefore, the excited state is not sufficiently considered in the conventional method, and the combustion center of gravity determined from the combustion pressure is more retarded than the combustion center of gravity determined based on the negative ion current as in the present embodiment. It is thought that it shifted.
- control method does not predict and calculate the instantaneous value of the thermal conductivity of the combustion gas from the combustion pressure as in the related art. This is a method of measuring the ion current and controlling the engine 1 based on the negative ion current. Therefore, according to the present embodiment, it is possible to reduce the calculation error of the combustion center of gravity, and it is possible to increase the control accuracy. In addition, control of the engine 1 without embedding a sensor or the like in the combustion chamber 5 can be easily performed.
- the control according to the present embodiment is control that adjusts the ignition timing to the MBT so that the maximum torque is obtained.
- the control according to the present invention is not limited to the above control.
- the control may be prohibited or the target value of the third crank angle G may be set to the target value of the embodiment (the target value when conforming to the MBT).
- the target value of the embodiment the target value when conforming to the MBT.
- the combustion center of gravity due to the negative ion current fluctuates greatly when a misfire occurs in an EGR state in which exhaust gas is recirculated to intake air, a lean air-fuel ratio state, a stratified combustion state, or the like. Therefore, it is possible to control the EGR rate, air-fuel ratio, etc., based on the fluctuation rate of the center of combustion per unit time so as to prevent misfire. That is, the control according to the present invention can be implemented as misfire prevention control of the engine 1.
- the third crank angle corresponding to the combustion center of gravity is calculated according to the above-described method. And at the same time, calculate the rate of change of the third crank angle.
- the EGR rate may be controlled so that the EGR rate decreases.
- the EGR rate can be controlled without adding a special detection sensor, and the misfire of the engine 1 can be prevented.
- the third crank angle corresponding to the center of gravity of combustion is calculated according to the method described above, and the rate of change of the third crank angle is calculated.
- the intake valve 9 and the exhaust The opening / closing timing of the intake valve 9 and the exhaust valve 10 may be controlled so that the overlap period of the valve 10 decreases. As a result, the valve timing can be controlled without burning the special detection sensor, and the misfire of the engine 1 can be prevented.
- the ignition timing can be adjusted to the MBT, for example, in a wide operating state, including when the combustion speed is low, etc., thereby improving fuel efficiency and reducing exhaust gas. , Or improvement of driver pyrity.
- the ignition timing can be adapted to the MBT and optimal or favorable combustion conditions can be achieved.
- the ignition timing is controlled so that the center of gravity of combustion becomes more retarded than MBT, knocking can be prevented, and the amount of NOx generated, especially among the exhaust gas components, can be reduced. it can.
- crank angle is detected by the crank angle detection sensor 19, and the calculation and the control are performed based on the characteristics of the negative ion current with respect to the crank angle.
- crank angle as used in the present invention merely means a parameter that indicates the progress of combustion, and a parameter that can be technically regarded as being equivalent to the crank angle (for example, the time elapsed since ignition, etc.). ) Can also be regarded as the “crack angle” here. This is because such parameters have a one-to-one correspondence with the crank angle. Therefore, for example, it is possible to specify the rising point of the negative ion current based on the actual crank angle, and to specify the peak point based on parameters other than the actual crank angle (for example, elapsed time). .
