Embodiment is acted on and effect
Water-jacket typ pre-burning ignition system according to involved by the present embodiment, because the ignition system has engine cycle pipe
Road and precombustion chamber water jacket, cooling water can be introduced from the water side of engine cycle pipeline and enter intake tunnel, logical from water inlet
Road enters into the first cooling water channel, then enters the second cooling water channel from the first cooling water channel, and cooling water ring is around pre-burning room housing stream
Dynamic and pre-burning room housing flows out after being exchanged heat, and the water after heat exchange is flowed into engine cycle pipeline finally by annular effluent trough
In, because the specific heat capacity of water is larger, and maximum temperature after being warmed is 100 DEG C, can be shifted the heat of pre-burning room housing
So as to being cooled down to pre-burning room housing, so, the water-jacket typ pre-burning ignition system of the present embodiment can not only allow cooling water energy
Directly from top outflow after being flowed into from bottom, it is to avoid flow blind angle, mobility is increased, and water is entered using circulation line
Row circulation, without addition equipment in addition, has saved fund, and also achieving carries out effective temperature-reducing, radiating, radiating to pre-burning room housing
Efficiency high, long service life.
In the present embodiment, because the outer wall of pre-chamber cavity housing is provided with radiating fin, on the one hand, so that the face of contact
Product increase, so that the cooling water that the heat of high temperature on pre-chamber cavity housing can be passed to quickly in the first cooling water channel
In；On the other hand, radiating fin can strengthen the flowing of water, produce stronger sinuous flow, and heat transfer coefficient is bigger, and radiating effect is also more
It is good.Because such setting enables to pre-burning room housing preferably to radiate, internal combustion engine is prevented to be burned.
In the present embodiment, because the outer wall of precombustion chamber water jacket is provided with first annular groove, first annular groove is provided with
Sealing shroud and cylinder head are sealed so that precombustion chamber water jacket can intactly with cylinder head palette, prevent cooling water from leaking into
In cylinder head, prevent cylinder head, precombustion chamber water jacket from being corroded, increase the service life of precombustion chamber water jacket.
In the present embodiment, due to being provided with the slot block that can be plugged between cylinder head inwall and precombustion chamber water jacket,
When cooling water is introduced for a long time from engine cycle pipeline, the incrustation scale in cooling water can be remained in the through hole of slot block, cold
But effect be likely to it is impacted, at this point it is possible to extract slot block and it is cleaned so that cooling water can smoothly from
Intake tunnel enters, and cooling effectiveness is uprised.
Above-mentioned implementation method is preferred case of the invention, is not intended to limit protection scope of the present invention.
