Coil-on-plug ignition capable of intelligently adjusting output voltage

Abstract

The invention relates to a coil-on-plug ignition, which comprises a silicon steel sheet core, a primary winding, a secondary winding, a shell, an integrated circuit comprising an ignition module, a sensor detection module and a control module, a high-voltage head assembly and a high-pressure spring, wherein the primary winding sleeves the outside of the core; the secondary winding sleeves the outside of the primary winding; the shell sleeves the outside of the secondary winding; the integrated circuit is located at the core end; the high-voltage head assembly is connected with the lower end of the core; the high-pressure spring is connected with the other end of the high-voltage head assembly; the sensor module in the integrated circuit of the coil-on-plug ignition can detect the running speed of a vehicle and an accelerator; and the control module can control voltage output. The coil-on-plug ignition can intelligently control the voltage output according to the different running speeds of the vehicle and the accelerator size. On one hand, the coil-on-plug ignition is prevented from being damaged, and on the other hand, normal work of an engine is ensured.

Description

technical field [0001] The invention relates to an ignition coil, in particular to a pen type ignition coil for intelligently adjusting output voltage. Background technique [0002] In the ignition system of a car engine, the primary coil and the secondary coil are used to convert the low voltage into a high voltage, and the high voltage makes the spark plug work and ignites the fuel mist. When the car is running, sudden acceleration and driving require more power to provide the engine to work. At the same time, it is also necessary for the ignition coil to provide a higher voltage to ensure the normal operation of the spark plug. [0003] At present, the ignition coils on the market are mainly pen-type ignition coils. The main protective measure to protect the ignition coils from voltage breakdown is to add an insulating heat-resistant layer between the iron core and the primary coil and the secondary coil. At present, the pen-type ignition coils on the market can only ou...

AI Technical Summary

Problems solved by technology

At present, the pen-type ignition coils on the market can only output one voltage. When the car needs more and more power and the high voltage output by the ignition coil is higher, the insulation and heat-resistant layer is more and more likely to break down.
