Description
Technical field:
The utility model belongs to the technical field of car engine, refers in particular to a kind of air directly spray device of motor.
Background technique:
The heart of reciprocating piston engine---automobile has just been approved by common people since being born, and the implantation of current large-scale electronics technology and the development of materials science, be subjected to people's favor more, this controls good fuel economy accurately nothing more than its instant response.
Carburetor is eliminated afterwards these years, the technology of various novelties constantly is developed, be representative wherein with the directly spray of engine driven supercharging, turbosupercharging, internal combustion oil of cylinder, Variable Valve Time, lift range variable, variable displacement, cylinder stopping technique, variable compression ratio, electromagnetic air valve, HCCI advanced technologies such as (homogeneous-charge compression-ignitions), the direction that is leading car engine to advance.
Below 10 big technology are independently grasped by each big automobile vendor of the whole world respectively in one's power, and because of the competitive spirit between each manufacturer, can not form an effectively associating between these technology.But some single factory has more technology and cooperation advantage, so brought up the birth of a collection of new technology.Relatively successful technical tie-up has:
Popular TFSI (turbosupercharging+internal combustion oil of cylinder directly sprays), promptly on the basis that internal combustion oil of cylinder directly sprays, set up a cover turbosupercharger, reduced the thermal loss of motor, thereby increased output power and reduced fuel consume, helpful for fuel economy and power character.
The Valvetronic of BMW (air valve correct-timing variable and variable valve lift control system, claim the electronics valve again), this motor has been save the throttle valve structure of conventional engines, has reduced pump and has inhaled loss, and then can save fuel consumption greatly, particularly when motor is in slow-speed of revolution district.Simultaneously, do not have the intake valve induction air flow ratio on every side of the Valvetronic motor of closure choked flow effect to accelerate, quickened the atomizing of fuel/air mixture, improved velocity of combustion.So the Valvetronic motor can also improve the output of engine power and moment of torsion and reduce discharging when improving fuel economy.
Honda VCM (variable cylinder management system technology), the VCM system can switch between three cylinders, four cylinders and complete six cylinder working patterns, and this system can allow vehicle guarantee that under the situation of the high-power outputs of any needs such as starting, acceleration or climbing whole six cylinders devote oneself to work.And cruise and hang down under the engine load operating mode in middling speed, the cylinder group that only turns round, i.e. three cylinders, back exhaust casing group quits work.When travel in medium acceleration, high-performance cruise and gentle slope, motor will be used four cylinders and turn round.Regulate discharge capacity according to the load variations size, the effect of fuel-economizing can think and.
Variable compression ratio, electromagnetic air valve, HCCI are respectively the exclusive patented technologies of Sa Bo, FIAT and benz.The unique target of these advanced technologies all is in order to make reciprocating IC engine export more powerful motivation, to accomplish fuel consume still less.Also find out simultaneously it only is that the associating of 2 technical elements just can produce enough horsepower, and effectively restrained oil consumption.But but these are limited to camshaft and timing mechanism, complex structure, and part is loaded down with trivial details.Though the electromagnetic air valve of FIAT has not had camshaft, can only realize simple several function combinations.
The utility model is under the situation of not invading above-mentioned any technical pattern patent and a kind of new technology of exploitation can be in this ten big leading technology be switched arbitrarily, and the loading condiction and the oil consumption that adapt to vehicle more flexibly show.
Summary of the invention:
The purpose of this utility model provides a kind of simple in structure, can realize various control, adapts to the loading condiction of vehicle and the air directly spray device of the motor that oil consumption shows more flexibly.
The utility model is achieved in that the air directly spray device of motor, it is characterized in that: be symmetrically arranged with main electronics air valve and secondary electronics air valve in the left and right sides of in-cylinder injector, the air valve mouth of main electronics air valve is arranged in the main jet gas port, and the air valve mouth of the injector valve of in-cylinder injector and secondary electronics air valve is arranged in the secondary puff prot.
Above-mentioned main electronics air valve is: be disposed with tappet, armature, return spring in the upper end of air valve mouth, bilateral symmetry at return spring is provided with solenoid valve, top at solenoid valve is provided with electric interfaces, in the arranged outside of tappet the pressurized gas interface is arranged.
The structure of above-mentioned secondary electronics air valve is identical with the structure of main electronics air valve.
The outstanding compared to existing technology advantage of the utility model is:
1, the utility model is simple in structure, utilize structure of the present utility model can with the supporting use of multiple control modes;
2, the utility model is the same with traditional EFI automotive engine system, all form by sensor, final controlling element and computer controlled system three parts, with the difference of traditional EFI automotive engine system be: (1), simplified the structure of cylinder head, (2), cancelled intake valve, (3), cancelled camshaft, and can realize various control;
3, the utility model can switch in the directly spray of engine driven supercharging, turbosupercharging, internal combustion oil of cylinder, Variable Valve Time, lift range variable, variable displacement, cylinder stopping technique, variable compression ratio, electromagnetic air valve, this ten big leading technology of HCCI (homogeneous-charge compression-ignition) arbitrarily, adapts to the loading condiction and the oil consumption performance of vehicle more flexibly.
