Description

一种数字模块控制汽油发动机工况的装置 技术领域  Device for controlling working conditions of gasoline engine with digital module
本发明涉及汽油发动机工况控制技术。 具体地说是一种同时控制摩托车 汽油发动机各种工况条件下的最佳点火提前角及可变进气调 的装置。 背景技术  The invention relates to a gasoline engine working condition control technology. Specifically, it is a device that simultaneously controls the optimal ignition advance angle and variable intake adjustment of a motorcycle gasoline engine under various operating conditions. Background technique
在现有技术中， 汽油发动机还大量采用化油器技术及 CDI 电子点火技 术， 但性能上主要存在两个不足之处， 一是空燃比不能自适应汽油发动机工 况变化， 二是点火提前角变化范围小， 不能自适应汽油发动机工况的变化， 而空燃比和点火提前角是影响汽油发动机效率的二个主要因素， 它们决定了 汽油发动机工作时的化学能及物理能转化利用率能否达到最佳效果， 因而也 决定了汽油发动机动力性能的优劣程度和油耗及排放量的高低。 为了提高汽 油发动机的工作性能， 出现了一些对化油器供气、 供油技术的改进型技术。 例如中国专利公告号为 1018228的专利技术。 该技术以节气门位置开关的负 荷信号和点火***的转速信号作为输入信号， 通过微机控制调节辅助进气的 数控阀， 对空燃比作了控制。 该技术未对不同空燃比时的点火提前角进行优 化控制， 而点火提前角是影响汽油发动机经济运行的重要参数， 故采用该技 术的汽油发动机油耗降低量只能达到平均 5 %— 8 %的水平， 排放效果并无 明显下降， 使该技术的先进性和适用性受到较大影响。又如现有的电喷技术， 也能控制最佳空燃比， 但采用这种技术的装置需要多个高精度传感器和 1套 造价昂贵且维护难度较大的喷油*** （喷油泵和喷嘴）， 因而导致其性能价 格比不够高， 这是阻碍此技术广泛应用于摩托车的最主要原因。 目前由于采 用此技术装置的成本不易降低等因素， 使其在单缸、 小排量的汽油发动机上 特别是摩托车汽油发动机上不能被广泛应用。 另外， 目前对最佳点火提前角 进行控制的技术装置的应用尚未有突破性发展。  In the prior art, gasoline engines also widely use carburetor technology and CDI electronic ignition technology, but there are two main shortcomings in performance. One is that the air-fuel ratio cannot adapt to changes in gasoline engine operating conditions, and the other is the ignition advance angle. The range of change is small, and it is not possible to adapt to changes in the operating conditions of gasoline engines. Air-fuel ratio and ignition advance angle are the two main factors that affect the efficiency of gasoline engines. They determine whether the chemical energy and physical energy conversion and utilization of gasoline engines are working. To achieve the best results, it also determines the pros and cons of gasoline engine power performance and the level of fuel consumption and emissions. In order to improve the working performance of gasoline engines, some improved technologies for the carburetor air supply and oil supply technologies have appeared. For example, Chinese Patent Publication No. 1018228. This technology takes the load signal of the throttle position switch and the speed signal of the ignition system as input signals, and controls the air-fuel ratio through the microcomputer control to adjust the auxiliary intake NC valve. This technology does not optimize the ignition advance angle at different air-fuel ratios, and the ignition advance angle is an important parameter that affects the economic operation of gasoline engines. Therefore, the fuel consumption reduction of gasoline engines using this technology can only reach an average of 5% -8%. Level, the emission effect has not decreased significantly, which has greatly affected the advancement and applicability of the technology. Another example is the existing EFI technology, which can also control the optimal air-fuel ratio. However, the device using this technology requires multiple high-precision sensors and an expensive fuel injection system (injection pump and nozzle). As a result, its performance-to-price ratio is not high enough, which is the main reason that prevents this technology from being widely used in motorcycles. At present, due to factors such as the difficulty in reducing the cost of using this technology device, it cannot be widely used in single-cylinder, small-displacement gasoline engines, especially motorcycle gasoline engines. In addition, there is currently no breakthrough development in the application of technical devices that control the optimal ignition advance angle.
本发明提供一种控制装置， 既能对空燃比作优化调节， 又能对不同空燃 比时的最佳点火提前角进行控制， 达到节油及降低排放的目的。 本发明的内容 The invention provides a control device, which can not only optimize the air-fuel ratio, but also control the optimal ignition advance angle at different air-fuel ratios, so as to achieve the purpose of saving fuel and reducing emissions.
