Abstract
Spark plug with cover is adopted in the firing system. Fuel cluster from fuel injector is jetted into the cover directly. Thus, concentrated combustible gas mixture of easy to ignite is formed around spark electrode, and subtle combustible gas mixture is formed outside the cover. Thus, the firing system guarantees reliable ignition and complete burning. The invention raises efficiency of engine, improves discharge, lowers fuel consumption rate as well as prevents deflagration so as to reduce noise.
Description
Technical field
The present invention relates to a kind of bell-type spark plug combustion system, it belongs to the spark-ignition engine field of burning pluralities of fuel.
Background technique
At present, in the spark plug sparking discharge moment of spark-ignition engine, the inflammable mixture flame that arcing is lighted is that beginning outside expansion spherical in shape passes to whole firing chamber near electrode gap.No matter be fuel such as burns gasoline or liquefied petroleum gas, spark-ignition engine inflammable mixture concentration under low operating mode is not high, is difficult to light.For lighting inflammable mixture smoothly, the means of taking usually are to strengthen the ignition energy of spark plug, and this not only consumes too much electric energy, and sparking-plug electrode is worn and torn too early.
Summary of the invention
In order to solve spark-ignition engine because of the rare excessively problem that is difficult to light of inflammable mixture concentration, the invention provides a kind of bell-type spark plug combustion system, this combustion system can make the inflammable mixture concentration around the sparking-plug electrode be enlarged to the spark ignition that is highly advantageous to, and make flame spread all over whole firing chamber rapidly, to reach power character and the Economy of improving motor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of bell-type spark plug combustion system, it mainly comprises a firing chamber of being made up of cylinder head, piston and cylinder liner.Oil nozzle has a notes fuel cluster to spray towards the spark plug direction.Its special way is: the head of above-mentioned spark plug is provided with a cover, this cover is presented recessed protruding curved surface shape, leave slit δ between the lower plane of cover top and cylinder head, make to spray to one of spark plug and annotate fuel cluster and can enter in the cover from slit δ, formation be easy to light than rich mixture.The ground electrode of one of a pair of igniting polar of spark plug is replaced by cover; The intracavity bottom of the ground electrode cover of spark plug is provided with a projection; Cover all is fixed on the body of spark plug with connecting tendon.
The basic functional principle of technique scheme is: allow one of fuel injector annotate the inner chamber that fuel cluster is directly injected spark plug head cover, make the igniting polar of spark plug be covered with denseer inflammable mixture on every side, the High Temperature High Pressure flame that the burning of inflammable mixture that spark plug is very easily lighted produces from the slit between cover and the cylinder head lower plane to around spray, light the combustion gas in the whole firing chamber rapidly, make whole combustion process rapid, perfect.
This combustion system the invention has the beneficial effects as follows: owing to can guarantee the inflammable mixture concentration around the plug ignition electrode in the cover, help spark ignition, created the condition of thin inflammable mixture burning for covering outer whole firing chamber, reach the raising engine efficiency, improve discharging, the purpose of fuel saving.And under high load,, avoided the generation of detonation because the flame jet velocity is fast, reduced noise.Preliminary test shows: even air fuel ratio reaches more than 100, also can burn by stable ignition, the thermal efficiency improves more than 10%, and noise reduces by 2 decibels.

Embodiment
In Fig. 1,2 illustrated embodiments, formed the firing chamber of motor by cylinder head 1, piston 2 and cylinder head 3.Fuel injector 4 tilts to be installed on the cylinder head 1.Spark plug 5 also is installed on the cylinder head 1, and makes between the top of spark plug 5 head cover 6 and cylinder head 1 lower plane by spacer 7 and to have suitable slit δ.One of fuel injector 4 is annotated the inner chamber that fuel cluster 8 is directly injected cover 6, makes the igniting polar of spark plug 5 form the inflammable mixture that denseer extremely helps lighting on every side.Light the flame that produces the High Temperature High Pressure inflammable mixture in cover 6 internal causes, slit δ between the lower plane through covering 6 top and cylinder head 1 to around ejection, light the thin inflammable mixture that the fuel cluster 9,10 by sparger 4 ejection forms, flame is diffused into whole firing chamber rapidly, finishes combustion process.
In the embodiment shown in Fig. 3,4, the effect that cover 6 has substituted ground electrode 13, cover 6 and centre electrode 12 igniting polar that partners.In order to improve the working life as ground electrode cover 6, another program is to be provided with projection 11 at cover 6 intracavity bottoms.Cover 6 all uses connecting tendon 14 to be fixed on the body of spark plug 5.
