Abstract
The present invention discloses an automobile electrothermal burner which comprises two parts of a fuel injector and a vaporizing electric heating unit which are arranged in a same shell body. The upper half part of the shell body is provided with the fuel injector while the lower half part is provided with the vaporizing electric heating unit. A nozzle of the fuel injector passes by a center perforation of a heat insulation base of the vaporizing electric heating unit and penetrates out of the lower end face of the insulator. In the present invention, the gas injected from a spray hole is the vaporized gas of directly spontaneous combustion, thereby simplifying the structure of the fuel injector, being beneficial to simplifying the structure of a combustion chamber and being convenient for installation and maintenance, etc. The more important thing is that the automobile electrothermal burner of the present invention can ensure the burning quality and full burning, and is beneficial to saving oil and reducing the pollution caused by tail gas emission to the atmosphere. Furthermore, the problem of detonation does not occur.
Description
Technical field
The present invention relates to automobile, belong to the motor car engine ignition system, is a kind of automobile electrothermic jet burner.
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, two nozzles generally are set in a firing chamber at least, the mixed gas that spray is denseer, the mixed gas that spray is rarer, establish 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 automobile electrothermic jet burner, enable using that no-spark plug ignition mechanism also can realize the spray combustion under the liquid fuel state, and when combustion spray can not have the air fuel ratio requirement, promptly the fuel that sprays from the spray orifice of nozzle does not require that must mix a certain proportion of air just auto-ignition combustion can take place.
Another object of the present invention provides a kind of automobile electrothermic jet burner, makes it simple in structure, installation, easy to maintenance, and can create certain technical specifications for simplifying chamber structure.
The technical conceive of the present invention of realizing above-mentioned purpose is: the fuel oil of the nozzle of flowing through is heated make it to reach vapourizing temperature, what spray from spray orifice is the combustion gas of vaporization fully that reaches self-ignition point.Concrete scheme of the present invention is, included oil sprayer consists predominantly of electromagnetic coil, valve body, spool, valve seat, spring, oil holding slot and nozzle, the present invention also includes a vaporization Electric heating appliance, this vaporization Electric heating appliance consists predominantly of a vaporization electric heater and an insulator, and the vaporization electric heater is embedded on the outer rim of insulator; Oil sprayer and vaporization Electric heating appliance are arranged in the same housing, the first half device oil sprayer of housing, Lower Half device vaporization Electric heating appliance, the nozzle of oil sprayer is set in the central hole of vaporization Electric heating appliance insulator, and passes the lower end surface of insulator.
The present invention as mentioned above, the electromagnetic coil of oil sprayer is arranged on the outer rim of valve body, is provided with the spring of overhead on spool in the valve body center hole, the sealing surface of spool and the suitable sealing of oil-feed metering-orifice on the valve seat.Said spool, the central part of its lower end surface are the hemisphere sealing surface of projection, and be suitable with the arc metering-orifice on this and the valve seat.The present invention is provided with oil holding slot in valve body bottom, oil holding slot is connected with fuel gallery on the valve body, and the oil-feed metering-orifice of valve seat is immersed in the oil holding slot.For preventing the fuel gas return-flow in the firing chamber, the upper end of insulator central hole is connected with the output channel of valve seat among the present invention, and can be provided with a safety check betwixt.Also can be positioned on the insulator outer rim of vaporization Electric heating appliance the vaporization electric heater above have heat dam, spread to oil sprayer top to reduce heat.
As mentioned above, advantage of the present invention mainly contains: what spray from spray orifice is the vaporization gas of direct spontaneous combustion, there have not been the oil sprayer of tradition and the matching problem of ignition mechanism, both simplified the structure of oil sprayer, help simplifying chamber structure, work such as convenient installation and maintenance, the more important thing is that the present invention can guarantee burning quality, and combustion gas there is not the air fuel ratio requirement, increased the area of contact of combustion gas and air on the contrary, make to help reducing the pollution of exhaust emissions by sufficient combustion, also can not produce the pinking problem atmosphere.
