Novel coil-on-plug ignition

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 ignition module, a circuit, 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 ignition module and the circuit are 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, and is encircled inwards in the middle part to form a baffle ring; and a conducting cylinder is put from one end of the spring, so that the condition that the end surface of the conducting cylinder and the spring are fastened and connected with a sparking plug is ensured. The novel coil-on-plug ignition can ensure the connecting stability of an ignition coil and the sparking plug, so that normal work of an engine is ensured; and the service lifetime of the ignition coil is prolonged.

Description

technical field [0001] The invention relates to an ignition coil, in particular to a novel pen type ignition coil. Background technique [0002] The reliability of the connection between the ignition coil and the spark plug of the automobile engine is very important. As far as the current technology is concerned, the energy of the ignition coil is generally transmitted to the spark plug by using a spring, and the connection between the ignition coil and the spark plug is through the spring against the end face of the spark plug or the spring It is placed on the end of the spark plug, which basically forms a line contact or a small area contact. When affected by environmental vibrations, it often becomes loose, resulting in unreliable connection, resulting in a decrease in energy transfer efficiency and affecting the normal operation of the engine; at the same time, Also shortens ignition coil life Contents of the invention [0003] In order to make up for the above-mentio...

AI Technical Summary

Problems solved by technology

[0003] In order to make up for the above-mentioned deficiencies, the present invention provides a connection structure between the ignition coil spring and the spark plug, which can ensure that the ignition coil spring and the spark plug have poor connection stability, low energy transfer efficiency, and affect the service life of the ignition coil. The stability of the connection with the spark plug ensures the normal operation of the engine and prolongs the service life of the ignition coil
