Description
(1) technical field
The present invention relates to a kind of low concentration gas motor, particularly a kind of super low concentration gas special engine.
(2) background technique
As everyone knows; Existing in the market low concentration gas motor must just can reach full power output in concentration about 15%; For example: the Z12V190 type low concentration gas rated output of generating set 500kW that Jinan Diesel Plant, Dongying triumph power generating machine factory produces when gas density 15% is above, can reach generated output 500kW; If gas density drops to 5%, generated output will drop to below the 150kW even can not send power.
(3) summary of the invention
The present invention is in order to remedy the defective of existing technology, and a kind of super low concentration gas special engine that can oepration at full load under the super low concentration methane gas of methane content 5%-15% is provided.
The present invention realizes through following technological scheme:
A kind of super low concentration gas special engine; It is characterized in that: comprise the mixed gas pipeline that is connected with the cylinder suction tude; Be provided with mixture control dish door in the mixed gas pipeline; Mixed gas pipeline front end connects pressurized machine, and the pressurized machine front end is connected with gas pipeline and air pipe line, is provided with gas control dish door in the gas pipeline; Be provided with air control butterfly door in the air pipe line, gas control dish door, air control butterfly door and mixture control dish door are controlled through combustion gas air fuel ratio closed loop control system.
This super low concentration gas special engine, combustion gas air fuel ratio closed loop control system is controlled three dish doors to the proper angle position automatically according to gas density, reaches the standard of minimum burning 5% gas density, reaches the requirement that motor continues rated power output simultaneously.The quantity of pressurized machine is one or more, forms one pole or multipole supercharging.
The invention has the beneficial effects as follows: this super low concentration gas special engine; When input super low concentration methane gas; Can oepration at full load, and reliability is high, thermal transition efficient is high, delivery temperature is low, has created good condition for making full use of a large amount of super low concentration gas.
(4) description of drawings
Below in conjunction with accompanying drawing the present invention is further described.
Accompanying drawing 1 is the structural representation of super low concentration gas special engine of the present invention.
Among the figure, 1 gas control dish door, 2 air control butterfly door, 3 mixture control dish doors, 4 pressurized machines, 5 combustion gas air fuel ratio closed loop control systems, 6 gas pipelines, 7 air pipe lines, 8 mixed gas pipelines.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
Among Fig. 1; This super low concentration gas special engine; Comprise the mixed gas pipeline 8 that is connected with the cylinder suction tude, be provided with mixture control dish door 3 in the mixed gas pipeline 8, mixed gas pipeline 8 front ends connect pressurized machine 4; Pressurized machine 4 front ends are connected with gas pipeline 6 and air pipe line 7; Be provided with gas control dish door 1 in the gas pipeline 6, be provided with air control butterfly door 2 in the air pipe line 7, gas control dish door 1, air control butterfly door 2 and mixture control dish door 3 are controlled through combustion gas air fuel ratio closed loop control system 5.Replace special-purpose venturi mixer on high concentration (more than 60%) the gas motor by pressurized machine 4; Gas control dish door 1 is united adjustment with air control butterfly door 2 and is adapted to variable concentrations gas (gas density is more than or equal to 5%) to satisfy the demand of burning, the rotating speed of mixture control dish door 3 control motors and power output.Combustion gas air fuel ratio closed loop control system 5 is controlled three dish doors to the proper angle position automatically according to gas density, reaches the standard of minimum burning 5% gas density, reaches the requirement that motor continues rated power output simultaneously.The quantity of pressurized machine 4 is one or more, and one is the one pole supercharging, forms multipole supercharging after a plurality of series connection.
During work, gas is through gas control dish door 1, and air is through air control dish door 2; Gas and air enter into pressurized machine 4 through air inlet pipeline, and air forms inflammable mixture with gas and enters in the cylinder through engine air inlet tube through mixture control dish door 3 after pressurized machine 4 mixes supercharging, acting after the plug ignition outburst; When in gas density 5%-15% scope, fluctuating; By combustion gas air fuel ratio closed loop control system 5, according to predefined program, the reference value of passing back with reference to lambda sensor; Provide gas control dish door 1, air control butterfly door 2 and mixture control dish door 3 corresponding angular orientations; Thereby guarantee that motor is in optimal operational condition all the time, the air fuel ratio of combustion gas simultaneously closed loop control system 5 can also be adjusted three dish doors and be in optimal operational condition all the time according to the variation of load simultaneously.With Z12V190 type 500KW super low concentration gas engine is example, when gas density 15% is above, can reach rated power 500kW, when 5% gas density, and the still sustainable 500KW long-time running of generated output.
