Abstract
If a kind of internal combustion engine New Type of Ignition System is additionally provided with a glow plug there are one the spark plug covered mounted on cylinder, and spark plug is equipped with interior electrode, and electric heating plug head is a heater, and interior electrode constitutes a pair of discharge electrodes with heater；The device had both had the advantages that directly controlling for spark ignition, but also with the high-energy ignition advantage of glow-plug ignition device, can realize the purpose for accurately controlling Lean burn engine process.
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 technology
Currently, using electric energy as there are two types of the devices of ignition energy in IC engine cylinder, one is spark ignition device, profits
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, igniting is 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 in energization using the heater on head, 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 indirect
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.
Invention content
According to current technology present situation, the present invention proposes that a kind of internal combustion engine New Type of Ignition System, the device both have spark
The advantages of directly controlling of igniting can be realized but also with the high-energy ignition advantage of glow-plug ignition device and accurately control thin mix
Close the purpose of gas combustion process.
If a kind of internal combustion engine New Type of Ignition System is additionally provided with one there are one the spark plug covered mounted on cylinder
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 constitutes a pair of discharge electrodes with heater.
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 with spark plug can be it is seperated independently installed, can also integrated installation in a ceramic insulation body.
The beneficial effects of the present invention are：When spark-discharge, heater surface is first lighted close to the gaseous mixture of spontaneous combustion, shape
At the fiery core that energy is larger, which removes to light again the Weak mixture of difficult point combustion, reach in this way can flexibly, accurately control a little
Fiery phase, and the purpose with larger lean flammability limit.
Description of the drawings
Fig. 1 is glow plug and spark plug independent installation structure schematic diagram；
Fig. 2 is the schematic diagram of glow plug and spark plug integrated installation in an insulator.
In figure：1, glow plug；2, heater；3, interior electrode；4, spark plug；5, cylinder head；6, shell；7, insulator.
Specific implementation mode
The invention will be further described in the following with reference to the drawings and specific embodiments, but invention which is intended to be protected is simultaneously
It is without being limited thereto.
Shown in Fig. 1, there are one spark plug 4 and glow plugs 1, spark plug 4 to eliminate external electrode, spark for installation in cylinder head 5
The interior electrode 3 of plug 4 and the heater 2 positioned 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, forms an energy bigger
Fiery core can light thinner fuel mixture due to the big many orders of magnitude of its energy ratio spark energy.In work
, can be according to the different operating modes of engine in work, by PWM wave mode, the temperature on 2 surface of control heater reaches best
Light effect.
As the improvement of said program, as shown in Fig. 2, the heater 2 of glow plug 1, the interior electrode 3 with spark plug 4, side by side
On a ceramics insulator 7, an additional shell constitutes a pair and puts between the inner electrode 3 and heater 2 of spark plug 4
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.
