Flame-throwing nozzle of engine

Abstract

The invention discloses a flame-throwing nozzle of an engine, which comprises a housing, wherein a porcelain insulator is arranged in the housing, a double-headed screw stem with a wiring screw cap, a conductor glass sealant, a central electrode with one end extending out of the porcelain insulator and a flame-throwing cap which is welded with the end part of the central electrode are arranged inthe porcelain insulator, the flame-throwing cap comprises a plane, the sharp edge of the plane forms a circle, the vertical distance between the plane and the end surface of the housing is greater than 8mm, an ignition gap formed by the flame-throwing cap and an engine cylinder cover is annular, and a heat capacity flame-throwing cavity is formed by the flame-throwing cap and the engine cylinder cover. The flame-throwing nozzle of the engine has the functions of electric spark ignition, flame throwing, heating for supporting combustion and the like and can realize the reliable, uniform and rapid completion of the whole combustion process. The flame-throwing nozzle of the engine can fundamentally eliminate the basic conditions of exhaust pollution of a vehicle, simultaneously greatly reduce the oil consumption, improve a variety of performances of the vehicle and prolong the service life of the engine.

Description

technical field [0001] The invention belongs to the field of engine manufacture, and in particular relates to the manufacture of an engine combustion system. Background technique [0002] With the wide application of automotive engine electronic technology, EFI engine and in-cylinder direct injection engine technology are constantly developing. Ordinary spark plugs can only start the ignition, and the ignition point is small and the ignition area is small. [0003] The working process of the existing spark plug is to generate electric sparks between the positive and negative poles of the spark plug or the flame nozzle with high voltage electricity. The piston takes about 30 milliseconds or so. The piston is extruded by high temperature and high pressure from the top dead center to push the piston down to about 4? The high temperature and high pressure suddenly drop around the temperature, and the remaining substances are forced to be excreted before they are completely bur...

AI Technical Summary

Problems solved by technology

[0005] The ignition area is small, the combustion speed is slow, and a large amount of fuel will be wasted and a large amount of oxygen molecules will be consumed during the ineffective work period of pre-ignition

Insufficient oxygen molecules will prevent the mixture from being completely combusted when the engine is working, resulting in serious exhaust pollution.
