Abstract
The utility model relates to an electrical control enrichment mixer for an engine, belonging to a combustible mixture control device for an engine. The device adopts a stepping enrichment valve to control the circulation area of the enrichment port and utilizes the electronic module of the engine to regulate the air-fuel ratio at real time according to the requirements of the combustible mixture under different working conditions. The device has the advantages of simple structure and reliable operation. The device improves the cold starting performance, the idle speed stability and the acceleration quality. Compared with the devices using liquefied petroleum gas and gasoline, the maximum power of the engine is not reduced, so the economy and power performances of the engine are improved and the drained pollutants are below the standard requirements.
Description
A kind of engine electric-controlled enriching mixer, it belongs to the engines combustible mixture control assembly.
The fuel system of existing incendivity multifuel engine mainly is made up of steel cylinder, decompressor, mixer, filter, solenoid valve and some control units.When using compressed natural gas to make fuel, generally need to adopt three grades of decompressions, and when using LNG Liquefied natural gas or liquefied petroleum gas (LPG) to make fuel, generally adopt second depressurized, post-decompression vaporized fuel forms inflammable mixture with air mixing in mixer, enter engine combustion again.For the different operating modes of motor, the concentration requirement of mixed gas is different: when starting, require extremely dense mixed gas; When idling or low-load, require dense mixed gas; When moderate duty, require rare mixed gas, to keep the Economy of motor; When big load, require dense mixed gas again, to keep the power character of motor.The mixer of the duel fuel engine that is using at present all is not provided with the enrichment-system according to working conditions change, to making starting difficulty or underpower.
The purpose of this utility model is: develop a kind of engine electric-controlled enriching mixer, it should provide the inflammable mixture of different air fuel ratios according to the working conditions change of motor, this device should simple in structure, reliable operation, makes motor have good startability, idle stability, acceleration, power character, Economy and low emission.
Technical solution of the present utility model is: a kind of engine electric-controlled enriching mixer, it mainly is made up of body, lid, diaphragm spring, diaphragm assembly, idle adjusting screw and spring.Special way of the present utility model is: above-mentioned diaphragm assembly is made up of diaphragm, punch holder, die holder, deflector and spool; The bottom of body is provided with closure and rotating shaft, and an end of rotating shaft is equipped with throttle position sensor; The passage of vaporized fuel import is provided with the enriching mouth, and the stepping upgrading valve of control enriching mouth circulation area is made up of two electromagnetic coils, rotor and valve rods, between rotor and the valve rod with being threaded.
Above-mentioned deflector is provided with 3～4 holes that diaphragm assembly upper and lower cavity is communicated.
Above-mentioned spool is provided with 4～6 road vent slots.
Above-mentioned valve rod is provided with the cone of regulating enriching mouth circulation area.
The guiding theory of above-mentioned technical solution is: engine electric-controlled enriching mixer is provided with enrichment-system, and this enrichment-system uses the stepping upgrading valve to control the circulation area of the enriching mouth that is located on the vaporized fuel passage.The load of throttle position sensor perception motor, combine with speed probe and cooling-water temperature sensor on being installed in motor, calculated, compare and judged by electronics module, the control step upgrading valve is opened big or is turned down the enriching mouth, and the inflammable mixture air fuel ratio of motor is adjusted to optimum value.
Effect of the present utility model is: this engine electric-controlled enriching mixer adopts the circulation area of stepping upgrading valve control enriching, by means of the electronics module of motor, implements to regulate according to the requirement of inflammable mixture air fuel ratio under the Under Different Work Condition of Engine.This apparatus structure is simple, reliable operation, cold starting performance, idle stability and the acceleration of motor have not only been improved, and using liquefied petroleum gas (LPG) to make fuel and using No. 90 gasoline to compare, the peak output of motor does not descend, improved Economy and power character, pollutant effulent all is lower than standard-required.
Description of drawings:
Accompanying drawing 1 is a kind of structure principle chart of engine electric-controlled enriching mixer.
Accompanying drawing 2 is structural drawing of stepping upgrading valve.
Be an embodiment of the present utility model below, description and accompanying drawing by to this embodiment provide details of the present utility model.
Fig. 1 is a kind of structure principle chart of engine electric-controlled enriching mixer.Among the figure, be divided into upper and lower cavity by the diaphragm assembly between body (1) and the lid (2), the diaphragm assembly is made up of diaphragm (3), punch holder (4), die holder (4a), deflector (5), diaphragm spring (6) and spool (10), and lean on screw-nut (5b) (10a) to tighten together, 3 holes that upper and lower cavity is communicated (5a) are arranged on the diaphragm assembly, diaphragm assembly and sleeve pipe (11) constitute gas valve, constitute air valve with the collar extension (1a) in the body (1), idle adjusting screw (14) and spring (13) are installed on the body (1).Closure (18) is fixed in the rotating shaft (19) by 2 screws (25), and the other end of rotating shaft (19) is equipped with throttle position sensor (20).This device is fastened on the intake manifold of motor by 4 bolts hole (21) on body (1) lower flange.
Fig. 2 is the structural drawing of stepping upgrading valve.In Fig. 1,2, the passage of vaporized fuel import (15) is provided with enriching mouth (16), and the stepping upgrading valve of being made up of two electromagnetic coils (24), rotor (23) and valve rod (22) is by the circulation area of the control enriching mouth of the cone (22a) on the valve rod (22) (16).
From Fig. 1,2 as seen, when the cavity of resorption of diaphragm assembly exists certain vacuum to spend, the diaphragm total performance can on move, open air valve and gas valve simultaneously, the mixing chamber that air and combustion gas will enter the diaphragm cavity of resorption mixes.Idle adjusting screw (14) can come together to regulate the engine idle rotating speed with closure (18).In engine start, idling, acceleration, when 90% load is above, by means of being installed in speed probe on the motor and cooling-water temperature sensor etc., electronics module as calculated, relatively and judge, the stepping upgrading valve is sent regulating command, the circulation area size of control enriching mouth, change the concentration of mixed gas, the inflammable mixture air fuel ratio that enters motor is adjusted to optimum value.
