Problems solved by technology

If the ignition coil is working abnormally, the fault light on the dashboard of the car will light up. At the same time, since the car engine has multiple cylinders, each cylinder has an ignition coil, that is, the engine is equipped with multiple ignition coils, and the ignition coil is abnormal. Sometimes, some cars themselves will display the faulty part as the ignition coil on the computer dashboard, but it is impossible to determine which ignition coil has the problem, so it is impossible to accurately determine the fault location
[0003] In the prior art, the whole set of abnormally working ignition coils is usually replaced or replaced. However, the replacement method takes a long time and the cost of the whole set of replacement is high, which cannot meet the maintenance requirements of saving time and cost at the same time. need

Abstract

The invention discloses a non-contact handheld multi-station automobile high-voltage ignition coil fault detector, which comprises a sensing antenna, an electromagnetic field signal amplifying circuit, an ignition signal processing circuit and a display circuit; the output end of the sensing antenna and the input of the electromagnetic field signal amplifying circuit The output end of the electromagnetic field signal amplification circuit is connected to the input end of the ignition signal processing circuit, and the output end of the ignition signal processing circuit is connected to the input end of the display circuit; the sensing antenna is used to sense the electromagnetic field signal when the ignition coil is ignited; The invention can facilitate users to compare the displayed ignition signal detection data in order to judge the fault of the ignition coil, that is, it adopts non-contact fast induction without any disassembly of the ignition coil, thus saving time and cost. Under the rapid detection of abnormal working ignition coil.

Description

technical field [0001] The invention relates to the technical field of automobile ignition coil detection, in particular to a non-contact handheld multi-station automobile high-voltage ignition coil fault detector. Background technique [0002] In the process of car maintenance, it is often necessary to judge whether the ignition coil is working abnormally. If the ignition coil is working abnormally, the fault light on the dashboard of the car will light up. At the same time, since the car engine has multiple cylinders, each cylinder has an ignition coil, that is, the engine is equipped with multiple ignition coils, and the ignition coil is abnormal. Sometimes, some cars themselves will display the faulty part as the ignition coil on the computer dashboard, but it is impossible to determine which ignition coil has the problem, so it is impossible to accurately determine the fault location. [0003] In the prior art, the whole set of abnormally working ignition coils is usua...
