| 摘要 |
An apparatus for in-vehicle testing of electronic fuel injection systems and/or electronic ignition systems. The apparatus selectively is able to sense, at least voltage, resistance and pulse width, and is capable of processing the sensed information, selectively displaying the voltage, resistance and pulse width information on a front face of a hand-held enclosure which contains the apparatus. The apparatus also includes sensors for oxygen sensing, temperature sensing and the like, and a pulse injector. The apparatus is specifically for use in diagnosing faults in and/or maintaining vehicle injection and ignition systems in a work shop or roadside breakdown situation. |
