Description
Technical field
This utility model relates to gas engine technical field, particularly relates to a kind of gas electricity generator lean burn and controls system.
Background technology
Gas engine is a kind of with the fuel gas such as liquefied gas, natural gas for comburant, replaces gasoline, diesel oil as the new energy engine novel, efficient of engine power.Burning fuel is needed during gas engine work.If the excessive fuel sprayed in cylinder, not only result in the waste of fuel, also can cause the series of problems such as engine water temperature is high, oil temperature is high, delivery temperature is high.If the fuel quantity sprayed in engine cylinder is less than normal, catching fire of electromotor can be caused again smooth, in turn result in the problem such as be short of power of electromotor.
To sum up, it is impossible to control electromotor very well and spray into the fuel of Sq in the correct time, will result in engine start difficulty, be short of power, the series of problems such as organism temperature is high.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of gas engine lean burn to control system for above-mentioned prior art, it can be ensured that electromotor is at the normal operation started and in running.
The technical scheme in the invention for solving the above technical problem is: a kind of gas engine lean burn controls system, it is arranged between source of the gas and electromotor, including the spark arrester set gradually, electromagnetic valve, pressure regulator, blender, supercharger, charge air cooler, motor intake manifold, and ECU, described mixer configuration has air filter；Separately it is provided with startup between described blender and motor intake manifold and supplements branch road, this startup supplements branch road and includes three-way valve, fuel control valve, described fuel control valve is arranged on the front end of motor intake manifold, and described three-way valve is adapter pressure regulator, blender and fuel control valve respectively；Described pressure regulator, fuel control valve and blender are connected with ECU signal respectively, and described ECU is also associated with the oxygen concentration sensor for detecting engine air-fuel ratio.
Above-mentioned lean burn controls the operation principle of system, engine startup, and the fuel ratio needed in cylinder is more, controls fuel control valve by ECU and is connected by three-way valve, makes fuel enter more in engine cylinder, it is ensured that electromotor normally starts.After engine start, the ratio of in-engine air-fuel ratio and air and combustion gas is detected, if air-fuel ratio is excessive, it was shown that air enters too much by oxygen concentration sensor, engine power can be caused not enough, improve gaseous-pressure by adjusting pressure regulator or adjust blender increase gas inlet amount；If air-fuel ratio is too small, it was shown that air inlet is too small, electromotor substrate temperature can be caused to cross the problems such as height, reduce gaseous-pressure by adjusting pressure regulator or adjust blender reduction gas inlet amount.
Compared with prior art, the utility model has the advantage of: provide the control system of a kind of gas engine lean burn, for the duty of gas engine different phase, accommodation combustion gas, air air inflow, it is ensured that the specified normal operation of electromotor.
Accompanying drawing explanation
Fig. 1 be in this utility model embodiment control system in the operating system of engine startup；
Fig. 2 be in this utility model embodiment control system in the operating system of normal work stage.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, this utility model is described in further detail.
As depicted in figs. 1 and 2, gas engine lean burn in the present embodiment controls system, it is arranged between source of the gas and electromotor, including the spark arrester 1 set gradually, electromagnetic valve 2, pressure regulator 3, blender 4, supercharger 5, charge air cooler 6, motor intake manifold 7, and ECU, blender 4 is configured with air filter 9；Separately it is provided with startup between blender 4 and motor intake manifold 7 and supplements branch road, this startup supplements branch road and includes three-way valve 10, fuel control valve 11, fuel control valve 11 is arranged on the front end of motor intake manifold 7, described three-way valve 10 adapter pressure regulator 3 respectively, blender 4 and fuel control valve 11；Described pressure regulator 3, fuel control valve 11 and blender 4 are connected with ECU signal respectively, and ECU is also associated with the oxygen concentration sensor 8 for detecting engine air-fuel ratio.
The operation principle of the present embodiment is, engine startup, and the fuel ratio needed in cylinder is more, controls fuel control valve by ECU and is connected by three-way valve, makes fuel enter more in engine cylinder, it is ensured that electromotor normally starts.After engine start, the ratio of in-engine air-fuel ratio and air and combustion gas is detected, if air-fuel ratio is excessive, it was shown that air enters too much by oxygen concentration sensor, engine power can be caused not enough, improve gaseous-pressure by adjusting pressure regulator or adjust blender increase gas inlet amount；If air-fuel ratio is too small, it was shown that air inlet is too small, electromotor substrate temperature can be caused to cross the problems such as height, reduce gaseous-pressure by adjusting pressure regulator or adjust blender reduction gas inlet amount.
The lean burn of said structure controls the system duty for gas engine different phase, accommodation combustion gas, air air inflow, it is ensured that the specified normal operation of electromotor.
In addition to the implementation, this utility model also includes the technical scheme that other embodiments, all employing equivalents or equivalence substitute mode are formed, and all should fall within this utility model scope of the claims.
