Description
Technical field
The present invention relates to automobile, belong to the motor car engine combustion system, is a kind of combustion-supporting purifying combustion device of engine.
Background technique
Energy saving is to realize the important measures of sustainable economic development, many countries all with energy-conservation as a state basic policy.Automobile is the oily rich and influential family that uses in the present age, and automobile energy-saving technology also must receive the very big concern of countries in the world, makes automobile energy-saving technology that development at full speed arranged.The conservation measures of automobile each position of automobile, aspect all carrying out making great efforts, particularly in technical field of automobile engine, cause the attention of each automobile superpower of the world especially, also obtained very gratifying success.Traditional motor car engine has diesel engine and petrol engine two classes, and in the existing power-saving technology, the in-cylinder direct injection stratified combustion of the high pressure co-rail system of diesel engine and petrol engine has all been obtained very fast development, and is extensively approved and use.But just present understanding also has many technical barriers to be properly settled as yet in the existing high pressure co-rail system, therefore, also is difficult to perfect the solution for the moment as problems such as pinking, pollution emissions.In petrol engine, for realizing the lean burn technology of stratified mixture combustion, one to two nozzle generally is set in a firing chamber, be provided with one the nozzle time-division main and auxiliary combustor, mixed gas that spray is denseer when adopting two nozzles, the mixed gas that spray is rarer is established a spark plug near the oil sprayer of spray than rich mixture, in order to igniting, the weak mixture oil sprayer is used for the burning air feed.The ignition system of combination like this, for guaranteeing ignition quality and realizing the homogeneous lean-burn, must make suitable complicated technology guarantee to control system of mounting structure, oil spout gas and the igniting of chamber structure, oil sprayer and spark plug or the like, therefore just make also that the existing lean-burn combustion system structure that becomes is comparatively complicated, install, debugging difficulty comparatively.
Summary of the invention
The purpose of this invention is to provide a kind of combustion-supporting purifying combustion device of engine, enable to realize not having when oil spout is lighted the requirement of air fuel ratio, the fuel oil that promptly sprays from nozzle opening does not require that must mix a certain proportion of air just can be lighted by the electrical spark of spark plug.
The purpose of this invention is to provide a kind of combustion-supporting purifying combustion device of engine, enable to create certain technical specifications for simplifying chamber structure.
Another object of the present invention provides a kind of combustion-supporting purifying combustion device of engine in addition, enables to realize easy for installation and can save the mounting point.
The technology technical conceive of the present invention of realizing above-mentioned purpose is: oil sprayer and ignition mechanism are combined into one, make jet and spark origination point be in same position, the fuel-steam of ejection (or combustion gas) can be lighted by electrical spark immediately.
Concrete scheme of the present invention is, includes oil sprayer and ignition mechanism, and oil sprayer consists predominantly of electromagnetic coil, valve body, spool, valve seat, spring and nozzle, and ignition mechanism consists predominantly of spark coil and spark plug; Oil sprayer and ignition mechanism are arranged in the same housing, the first half device oil sprayer of housing, and Lower Half device spark plug, intermediate portion is equipped with spark coil.Among the present invention, the nozzle of oil sprayer is located in the central hole of spark plug insulator, and passes the end face of insulator, and this nozzle is electrically connected with spark coil, then this nozzle that is become generating (just) electrode of spark plug.Have a central hole in the middle of the spark coil magnet among the present invention, this central hole upper end is connected with the output channel of valve seat, and the lower end is connected with nozzle.
Valve body among the present invention is provided with the spring of overhead on spool in its center hole, said electromagnetic coil is arranged on the outer rim of this valve body.The present invention is provided with oil holding slot (can claim storage to press the chamber, as follows) concerning combustion gas in the valve body bottom, fuel-displaced (gas) hole on the valve body communicates with this oil holding slot (chamber is pressed in storage), and the arc metering-orifice on the valve seat is immersed in this oil holding slot.
Spool among the present invention, the central part of its lower end surface are the hemisphere sealing surface of projection, and be suitable with the arc metering-orifice on the valve seat.
The present invention is equipped with a shell on the spark plug insulator outer rim, and is provided with through hole at the end face center of this shell.This shell is the sparking electrode of spark plug.Be provided with this shell end face one suitable distance of nozzle-end indentation of spray orifice, extend at least one tip on this nozzle face edge.
Said the present invention like this, fuel oil (or combustion gas) enters fuel gallery on the valve body from being positioned at fuel oil oil inlet hole on the valve body.When electromagnetic coil was switched on, spool was opened the valve seat mouth thereby be raised the back under the effect of electromagnetic force, fuel oil (gas) then from the nozzle spout of the concentricity setting of spark plug spray, at this moment, control ignition coil pilot spark plug generation electrical spark, the combustion vapour of ejection is then lighted by electrical spark and is burnt.Spring in the electromagnetic coil dead electricity, valve body promotes spool and is pressed on the valve seat, and jet stops oil spout (gas).
For preventing that the combustion gas in the firing chamber under high pressure refluxing, the present invention can be provided with a safety check between the central hole of nozzle and spark coil magnet.
When the fuel oil state is provided, for make the combustion gas that sprays from the nozzle spout is pure vaporization gas, to guarantee ignition success rate and to improve combustion efficiency, the present invention is equipped with the vaporization electric heater on the spark plug insulator outer rim,, make it to become completely and from spout, spray again behind the vaporization gas the fuel Heating in the nozzle by this vaporization electric heater.The present invention is overheated because of the electric heater of being vaporized influences as members such as spark coil, shells for preventing nozzle the place ahead (top), can have heat dam above being positioned at electric heater on the spark plug insulator outer rim.
Advantage of the present invention as mentioned above mainly contains: 1, because jet and spark origination point are in same position, and igniting covers nozzle exit area, fuel-steam (or combustion gas) after ejection is vaporized by the nozzle heating can be lighted by electrical spark immediately, this while spraying into combustion regime, both can not have the fuel air ratio requirement, and can not produce the pinking problem yet.2, in the cylinder all be the kinetic energy vaporized fuel owing to spray into, increased the area of contact of combustion gas and air, make sufficient combustion, with of the pollution of minimizing exhaust emissions to atmosphere.3, so, help simplifying chamber structure, also made things convenient for work such as installation and maintenance because igniting and fuel injection are the conflicting problems that same mouth does not exist cylinder cap nozzle and igniting.4, because combustion-supporting purifying combustion device of engine of the present invention is to adopt the fuel vapour vaporization to surpass spontaneous ignition temperature spontaneous combustion and electrion auxiliary firing technology,, is suitable for multifuel engine and uses so can use various fluid fuels.
