Automobile engine strong-force high-tension ignition wire

Abstract

The invention relates to an automobile engine strong-force high-tension ignition wire. Because the existing automobile engine high-tension ignition wire is continuously used until now for long term, the product structure, the applied materials and the technical parameters of the automobile engine high-tension ignition wire are very inapplicable to the rapid development of the current automobile industry. In the invention, the structure, the technical parameters and the like of the product are improved dramatically, so that energy saving and emission reduction can be obtained, the engine driving force is increased, and the interference of high-frequency electromagnet waves generated by sparks is prevented. The invention has the main technical measures that (1) one sealed copper (aluminum) foil shielding layer is arranged in the wire structure, the high-frequency electromagnet waves are utilized to produce the skin effect, so that the high-frequency electromagnet waves can not penetrate through the shielding layer, and strong shielding effect can be obtained; the DC resistance of a reactance damping type conducting wire core is reduced to 500-1000 ohm / m under the condition of (1), so that the ignition current can be increased by multiple times, i.e. the ignition energy is increased by multiple times; and (3) the weaving of semiconducting carbon fiber substitutes for the waving of usual glass fiber, the mechanical strength is increased, and meanwhile, the damage of the outer surface of a high-tension insulating layer by corona can be eliminated due to semiconduction and grounding.

Description

1. Technical field: [0001] The invention relates to a high-voltage ignition system of an automobile engine. The high-voltage ignition wire is a very important component in the system, and its product quality and technical content will directly affect the technical performance of the automobile and the effect of energy saving and emission reduction. 2. Background technology: [0002] 2.1 Regarding the conductive core of the high-voltage ignition wire: [0003] Automobile is a means of transportation commonly used in the world, with a huge annual production and sales volume, and it is a pillar industry in the national economy. Therefore, some industrialized countries have relevant technical standards for this product, such as: International Organization for Standardization ISO 3808 / 1 and 3808 / 2; my country's GB / T14820-93; American Society of Automotive Engineers SAE J2031DEC2001 and Japanese Industrial Standard JISC3409, etc. In order to reduce the interference of the high-fr...

AI Technical Summary

Problems solved by technology

Insufficient spark energy in the cylinder will reduce the driving force of the car; incomplete fuel combustion will increase the fuel consumption and harmful emissions of the car

Therefore, the anti-high-frequency electromagnetic interference cannot be solved solely by increasing the resistance value of the conductive core.

[0004] At present, resistive damping conductive wire cores on the market are rarely used because the resistance value is too large and unstable

my country's GB / T14820--93 standard for high-voltage ignition wires for road vehicles stipulates that the DC resistance of the resistance-type damping wire core is not greater than The direct resistance of the reactance type damping core is not greater than However, in the ISO 3808 / 1 and 3808 / 2 and SAE J2031DEC2001 standards, there are no specific regulations on the DC resistance value of the conductive core
