Ignition coil testing system

Abstract

The invention discloses an ignition coil testing system, comprising: a control unit, an environment simulation device, a signal generator, an oscilloscope, a temperature sensor, an air pressure sensor, a programmable DC power supply and an ignition coil; the temperature sensor and the air pressure sensor are arranged in the environment simulation device Inside; the ignition coil is installed in the environment simulation device, and the signal generator is respectively connected with the control unit and the excitation end of the ignition coil; the programmable DC power supply is respectively connected with the control unit and the primary coil of the ignition coil; the oscilloscope is respectively connected with the control unit and the ignition coil The ignition terminal connection. The present invention and its preferred solution can simulate the environmental conditions of actual working conditions, and the conditions for triggering ignition can be adjusted flexibly, providing a comprehensive and perfect test platform for the development of ignition coils, thus overcoming the lack of consistency in existing test methods , unstable results, and defects that cannot meet development needs.

Description

technical field [0001] The invention relates to an ignition coil performance test, in particular to an ignition coil test system. Background technique [0002] The ignition coil of the engine is one of the necessary parts of the fuel vehicle. It is responsible for the ignition of the mixture of fuel and air in the engine. Therefore, it is especially necessary to detect the performance of the ignition coil. [0003] At present, the performance detection method of the ignition coil has the following defects: [0004] The ignition coil works under the AC signal with a single frequency, which is not consistent with the actual working conditions of the engine, and the test results lack consistency; The test results are unstable; moreover, the test method is single and lacks a comprehensive test environment that simulates the conditions of the vehicle engine, because in actual working conditions, the engine is working dynamically, and the voltage and frequency of use of the ignit...

[0004] The ignition coil works under the AC signal with a single frequency, which is not consistent with the actual working conditions of the engine, and the test results lack consistency; The test results are unstable; moreover, the test method is single and lacks a comprehensive test environment that simulates the conditions of the vehicle engine, because in actual working conditions, the engine is working dynamically, and the voltage and frequency of use of the ignition coil are changing. A single standard to measure the performance of ignition coils cannot fully meet the development needs of ignition coils
