Description
Technical field
This utility model belongs to the part of electromotor and in particular to a kind of control structure of natural gas engine supercharger fills
Put.
Background technology
With the strict demand to environmental protection for the various countries, it is that the aerofluxuss of diesel engine must reach the discharge standard of state IV first, this
Sample just promotes the development of natural gas engine.Most of China natural gas engine is substantially and enters on the basis of diesel engine
The research and development of row, wherein admission pressure are to determine one of major parameter of natural gas engine performance indications, therefore mostly using increasing
In pressure, cold mode is improving its dynamic property and economy.The supercharger that conventional belt has mechanical vent valve is difficult to meet gas engine
Requirement, limited by production specifications and level of processing simultaneously, cause supercharger produce unified standard index be difficult to
Meet and require.The utility model proposes supercharger is used for using pressurized electrically controlled electromagnetic valve (automatically controlled exhaust gas by-pass valve) technology,
Using automatically controlled exhaust gas by-pass valve, supercharger is exitted, and for different operating mode real-time regulation boost pressures, compensate for passing
The shortcoming that the hysteresis quality etc. of system mechanical supercharger is not enough, improves the dynamic property of electromotor and economy it is ensured that producing one
The requirement of cause property.
Content of the invention
The purpose of this utility model is to provide a kind of device controlling supercharger by automatically controlled exhaust gas by-pass valve.
The technical solution of the utility model is：The control structure of natural gas engine supercharger includes：Automatically controlled exhaust gas bypass
Valve, ECU (ECU), electromagnetic valve, pressure transducer, gas engine, charge air cooler and turbocharger etc..Combustion gas is sent out
Motivation is connected with turbocharger, and the escape pipe of automatically controlled exhaust gas by-pass valve is connected with the vent valve of turbocharger；Breather valve
Communicate with air；Air inlet pipe is connected with the vacuum tube in gas engine inlet manifold；Automatically controlled exhaust gas by-pass valve pass through wire harness with
ECU connects.Gas engine is provided with air inlet pressure sensor, and boost pressure signal reaches ECU, from the air of turbocharger
Gas engine inlet manifold is entered after charge air cooler heat exchange.
Its principle is, by automatically controlled exhaust gas by-pass valve and turbocharging synergism, to adjust admission pressure, that is, utilize electricity
Control exhaust gas by-pass valve to control the air inflow of turbocharger.
Feature of the present utility model and beneficial effect are using automatically controlled exhaust gas by-pass valve, supercharger to be exitted, and
Can be with real-time regulation boost pressure, the shortcoming that compensate for turbocharger hysteresis quality, improve dynamic property and the economy of electromotor
Property is it is ensured that the requirement of conformity of production.The design of this apparatus structure is simple, and pressurized electrically controlled electromagnetism valve opening is flexible, control accurately,
Can control pressure ratio under the big load for high speed, improve the thermal efficiency of electromotor.
Brief description
Fig. 1 is this utility model principle and structural system figure.
Specific embodiment
Below in conjunction with accompanying drawing and by specific embodiment, structure of the present utility model is further described.
The control structure of natural gas engine supercharger, its structure composition is：Gas engine 1 and turbocharger 2 phase
Connect, the escape pipe 3-1 of automatically controlled exhaust gas by-pass valve 3 is connected with the vent valve 2-1 of turbocharger；Breather valve 3-2 and big gas phase
Logical；Air inlet pipe 3-3 is connected with the vacuum tube 1-1 in gas engine inlet manifold.Automatically controlled exhaust gas by-pass valve pass through wire harness with
ECU4 connects, and gas engine is provided with air inlet pressure sensor 1-2, and boost pressure signal reaches ECU, from turbocharger
Air enters gas engine inlet manifold after charge air cooler 5 heat exchange.ECU passes through unlatching and the pass of solenoid valve control breather valve
Close.
Work process of the present utility model is：ECU receives gas pedal voltage signal, converts thereof into load signal, then
Calculate and will reach the air inlet goal pressure (MAP target) needing during this load；When the admission pressure of electromotor raises, waste gas
Bypass valve is opened, and vent valve is connected with breather valve and started to exit, and waste gas is discharged without turbocharger, from automatically controlled exhaust gas bypass
Valve is discharged, thus reducing admission pressure, makes air inlet goal pressure reach MAP desired value.Then electronic throttle of engine enters again
Row adjustment, makes the pressure reduction before and after electronic throttle reach desired value, continuous adjustment exhaust gas bypass during adjustment air throttle
The aperture of valve, keeps MAP pressure value consistent with desired value.When admission pressure is not enough, breather valve closing, intake valve and air outlet valve
Connect, pressure is adjusted by turbocharger vent valve it is ensured that enough boost pressures.
