Description

CG125型发动机点火系统综合调试仪 CG125 engine ignition system integrated debugging instrument

技术领域 FIELD

[0001] 本发明是涉及摩托车点火系统综合调试的仪器,特别是针对CG125型发动机用点火提前角可调式点火器,能量可调式点火器。 [0001] The present invention relates to integrated debugging instrument motorcycle ignition system, particularly for CG125 type engine ignition advance angle adjustable igniter, ignition energy is adjustable.

背景技术 Background technique

[0002] 新一代发动机的发展面临着动力性、经济性和污染物排放三方面性能不断提高的挑战。 [0002] the development of a new generation of engines faced power, economy and emissions performance continues to improve in three areas of challenge. 公知的,通过大幅度提高点火能量(温度、磁场、电场)来提高燃烧速率和充分度的方法,可以达到综合改善内燃机性能的目的。 Known, by a substantial increase ignition energy (temperature, magnetic field, electric field) and a method to increase the burn rate sufficient degree, we can achieve the purpose of comprehensive improvement of the engine performance. 实现高能量点火,要加大点火能量,建立高温强电磁场。 High energy ignition, to increase the ignition energy, the establishment of high temperatures and strong electromagnetic fields. 如果采用高能量点火,同时加大火花塞间隙、延长火花持续时间,这都有利于火焰核的形成从而可以拓宽混合气的燃烧极限。 If high-energy ignition, while increasing the spark plug gap, extended spark duration, which are conducive to formation of a flame kernel can be broadened so that the combustion limit air-fuel mixture. 强大的点火能量,可以保证火核生长速度快,不失火。 Powerful ignition energy, can fire nuclear ensure fast growth rate, not fire.

[0003] 为满足日益严格的排放法规,同时降低燃油消耗的一个有效途径是发动机的稀薄燃烧,该稀薄燃烧技术也是内燃机技术发展的重要方向之一。 [0003] In order to meet increasingly stringent emissions regulations, while reducing fuel consumption in an effective way is a lean burn engine, one of the combustion technology is an important technological development of the internal combustion engine lean. 汽油机燃用稀薄混合气,可以降低燃油消耗量、减少有害的废气排放。 Gasoline Fueled with lean mixture, can reduce fuel consumption and reduce harmful emissions. 实现各工况的稀混合气燃烧,是提高经济性,并实现机内净化,降低一氧化碳及碳氢排放的综合最佳方案。 Realizing the lean burn operating conditions of combustion, improve the economy and realize the machine cleaner, carbon monoxide and reduce the overall best hydrocarbon emissions. 对稀混合气使用常规的点火方式会造成点燃困难,而高能量点火正好弥补这一不足。 Conventional ignition of lean mixture will cause difficulties lit, high-energy ignition and make up for this shortfall. 高能量点火可以扩大空燃比,实现超稀混合气燃烧,是实现稀薄燃烧的关键。 High energy ignition can expand the air-fuel ratio to achieve ultra-lean-burn, it is key to achieving lean combustion.

[0004] 点火时刻的控制是提高发动机性能的另一个要素。 [0004] The ignition timing control is another element to improve engine performance. 燃烧质量好坏与点火时刻密切相关,点火系统必须在合适的时刻点燃混合气。 The quality is closely related to combustion ignition timing, ignition system must ignite the mixture at the right time. 最佳点火时刻应该能保证发动机燃烧产生的有用功最大,热量利用率最高,此时气缸内最高燃烧压力在上止点后一定曲轴转角范围内产生。 Optimum ignition timing should be able to guarantee the maximum useful work, the maximum utilization of the heat of combustion of the engine, when the maximum in-cylinder combustion pressure generated in the top dead center in a crank angle range after a certain point.

[0005] 基于以上的背景,行业都要调试点火系统。 [0005] The ignition system must debug Based on the above background, industry. 目前,CG125型发动机用点火系统调试基本上都是用某个固定型号、固定结构的点火器。 Currently, use of CG125 engine ignition system debugging basically with a fixed type, the igniter fixing structure. 基本上无法对点火系统进行大幅度的改 Basically can not make drastic changes to the ignition system

口ο Mouth ο

[0091] 参照图11、图14,ECU首先根据点火信号控制模块输出的信号计算周期T。 [0091] Referring to FIG 11, FIG 14, first ECU calculation cycle signal in accordance with an ignition signal output from the control module T. 参照图13,两个正脉冲前沿的时间差就等于周期,同理两个负脉冲前沿的时间差也等于周期。 Referring to FIG. 13, two positive pulses on the leading edge equal to the period of the time difference. Similarly two negative pulse edge is also equal to the period of the time difference. 本发明采用前者,因为正脉冲过后马上要准备点火。 The present invention employs the former, because the positive pulse immediately after ignition to be prepared. 如果采用测试负脉冲前沿,则会出现点火不及时现象。 If test negative pulse edge, not timely ignition phenomenon occurs. 由周期可以计算出转速,从转速得知点火提前角度。 Period can be calculated by the rotational speed, the speed that the ignition advance angle.

[0092] 32位定时器TO通过检测两个连续的正脉冲或负脉冲的时间得出,然后由E⑶计算出发动机转速,通过查表方式得出该转速下点火提前角和点火能量。 [0092] 32-bit timer TO detected by two consecutive positive or negative pulse of the derived time, is then calculated from E⑶ the engine speed, the ignition advance angle obtained at this rotational speed and the ignition energy by table lookup. 当工作在直流电感式点火模式下,ECU计算出功率晶体管的导通时间,然后以此为依据计算并设置定时器延迟时间。 When operating in direct current sense ignition mode, the ECU calculates the power transistor conduction time, and then as the basis for calculating the delay time and sets a timer. 定时器起动时,ECU模块发出信号控制功率晶体管导通,待定时器溢出后再切断功率晶体管电流,从而在点火线圈的次级线圈上感应出点火所需的高电压。 When the timer starts, the ECU sends a signal to control the power transistor module is turned off after the timer overflow until the power transistor current, thereby inducing a high voltage required for ignition in a secondary winding of the ignition coil. 当工作在交流电容式点火模式下,ECU计算出高压储能电容电压,然后输出参考电压给数字调节稳压电路8,控制高压储能电容电压,从而控制点火能量。 When operating in AC capacitive ignition mode, the ECU calculates the high-voltage energy storage capacitor voltage, then adjust the output reference voltage to the digital voltage regulator circuit 8 controls the high voltage energy storage capacitor voltage, thereby controlling the ignition energy. ECU根据点火提前角计算并设置定时器延迟时间。 ECU calculates and sets a timer the delay time of the ignition advance angle. 待定时器溢出后输出控制电压令大功率可控硅,SCR2,导通,高压储能电容对交流点火线圈放电,点火线圈的次级线圈上感应出点火所需的高电压。 After the timer overflow control output voltage order power thyristor, SCR2, turned on, the AC high-voltage energy storage capacitor discharge ignition coil, an induced high voltage required for ignition of the secondary winding of the ignition coil.

[0093] 在实时控制过程中,单片机PIC16F630在计算出当前转速后,通过查表及相应计算得出该转速下直流点火大功率场效应管Q18的导通时间,然后计算出定时器的延迟时间,并起动定时器。 [0093] In the real-time process control, the microcontroller PIC16F630 in the calculation of the current speed, and a respective look-up table is calculated at this speed DC ignition power FET Q18 conduction time, and then calculates the delay time of the timer and start the timer. 待定时器溢出后立刻发出控制信号,关断直流点火大功率场效应管Q18, 实现点火。 Timer Overflow be sent immediately after the control signal, the ignition is turned off the DC power FET Q18, achieve ignition.

[0094] 参照上表、图11,N是以正脉冲前沿为基准的延迟时间,用于控制点火的时间,即点火提前角的。 [0094] Referring to the table, FIG. 11, N is a positive pulse edge delay time reference, for controlling the ignition time, i.e., the ignition advance angle. 发动机点火提前角是指从点火时刻起到活塞到达压缩上止点,这段时间内曲轴转过的角度。 Engine ignition advance angle is played piston reaches the compression top dead center, during which time the crank angle turned the ignition timing. 发动机在运转时,可以通过对N的控制来实现对点火提前角的控制。 The engine is running, it can be controlled to achieve control of the N spark advance angle. M是对点火线圈的充电时间。 M is the charging time of the ignition coil. 由于电感式点火系统的储能方式是靠点火线圈本身来完成的,因此点火线圈需要一定的充电时间来实现能量的积累,M就是对点火线圈的充电时间。 Since the inductive storage ignition system mode is accomplished by the ignition coil itself, thus charging the ignition coil will take some time to achieve the accumulation of energy, M is the charging time of the ignition coil.
