Description
Technical field
It is specifically a kind of in internal combustion engine compression stroke the invention belongs to a kind of igniter for internal combustion engine, utilize electricity
I.e. a kind of internal combustion engine New Type of Ignition System of igniter of the fuel mixture in cylinder can be lighted.
Background technique
Currently, one is spark ignition device, benefits using electric energy as there are two types of the devices of ignition energy in IC engine cylinder
With the discharge spark between spark plug inner electrode and external electrode, the fuel mixture in cylinder is lighted, this device belongs to direct control
System, ignition phase control flexibly, it is accurate, but ignition energy is limited, when in cylinder gaseous mixture than it is leaner when, light a fire unstable,
It may even happen that phenomenon of catching fire.This igniter is now widely used on the petrol engine of equivalent proportion burning；It is another
Electric ignition device is called glow plug, is to be generated heat using the heater on head in energization, generates high warm face, light cylinder
The advantages of interior gaseous mixture, this igniter is that ignition energy is big, can light thin gaseous mixture, the disadvantage is that belonging to indirectly
Control, the flexibility of ignition phase control and precision are all poor, are only used on the assisted cold start of diesel engine at present.
Summary of the invention
According to current technology status, the present invention proposes a kind of internal combustion engine New Type of Ignition System, which both has spark
The advantages of directly controlling of igniting is able to achieve but also with the high-energy ignition advantage of glow-plug ignition device and accurately controls thin mix
Close the purpose of gas combustion process.
A kind of internal combustion engine New Type of Ignition System is mounted on the spark plug that cylinder covers equipped with one, is additionally provided with one
A that the glow plug that cylinder covers is screwed in by screw thread, spark plug is equipped with interior electrode, and electric heating plug head is a heater,
Interior electrode and heater constitute a pair of discharge electrodes.
In order to reach good discharge effect, glow plug heater at a distance from electrode in spark plug 0.5~2mm it
Between.
Glow plug can be seperated independently installed with spark plug, also can integrate and is mounted in a ceramic insulation body.
The beneficial effects of the present invention are: when spark-discharge, first light gaseous mixture of the heater surface close to spontaneous combustion, shape
At the biggish fiery core of energy, which goes to light the Weak mixture of difficult point combustion again, reach in this way can it is flexible, accurately control a little
Fiery phase, and the purpose with larger lean flammability limit.
Detailed description of the invention
Fig. 1 is glow plug and spark plug independent installation structure schematic diagram；
Fig. 2 is glow plug and spark plug integrated installation in an intracorporal schematic diagram of insulation.
In figure: 1, glow plug；2, heater；3, interior electrode；4, spark plug；5, cylinder head；6, shell；7, insulator.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, but invention which is intended to be protected is simultaneously
It is without being limited thereto.
Shown in Fig. 1, a spark plug 4 and glow plug 1 are installed in cylinder head 5, spark plug 4 eliminates external electrode, spark
The interior electrode 3 of plug 4 and the heater 2 for being located at 1 head position of glow plug are close, gap ideal distance between 0.5~2mm,
Both it is exposed in engine combustion room.When work, glow plug 1 is powered, and heater 2 generates high temperature, heats the combustion on its surface
Expect gaseous mixture, make gaseous mixture close to spontaneous combustion but not up to spontaneous combustion, when piston is run near top dead-centre, spark plug 4 it is interior
Electrode 3 generates spark against 2 surface-discharge of heater, lights 2 surface of heater close to the gaseous mixture of spontaneous combustion, is rolled into a ball and mixed due to this
Gas is closed before being ignited already close to spontaneous combustion, therefore the flame on 2 surface of heater can rapidly develop, and it is bigger to form an energy
Fiery core can light thinner fuel mixture due to the big many orders of magnitude of its energy ratio spark energy.In work
In work, the temperature on 2 surface of heater can be controlled, reaches optimal by PWM wave mode according to the different operating conditions of engine
Light effect.
As an improvement of the above scheme, as shown in Fig. 2, the heater 2 of glow plug 1, the interior electrode 3 with spark plug 4, side by side
It is mounted on a ceramics insulator 7, an additional shell, a pair is constituted between the inner electrode 3 and heater 2 of spark plug 4 and is put
Electrode.The benefit of this design is that mounting process is relatively good.
To sum up, this igniter both has the advantages that directly control, and accurate, the flexible control of ignition phase may be implemented
System the advantages of but also with high-energy ignition, can expand lean flammability limit on a large scale.
