Description
Technical field
The present invention relates to internal-combustion engine inflammable mixture air inlet control field, specifically, is a kind of charge inter cooling air-intake of combustion engine by-pass governing device.
Background technique
The control of the inflammable mixture of internal-combustion engine is particularly important in field of internal combustion engine, at present, exhaust gas turbocharge is supercharging mode the most effective and general in boosting internal combustion engine, with a pressurized machine because exhaust gas turbocharge rated flow excursion is little, cause environmental suitability poor, when running in different environment, efficiency of turbocharger change greatly.Unit operation requirement must could be met from new matched with pressurization device when environment altitude change is larger; Because bypass exhaust temperature is high during employing exhaust gas bypass control system system, high to equipment Requirement, equipment cost is high; And when bypass amount controls the generation easily not causing internal-combustion engine tourist bus phenomenon at that time.
Summary of the invention
In order to solve the problem, the present invention proposes a kind of charge inter cooling air-intake of combustion engine by-pass governing device, connecting bypass valve on pressure stabilizing cavity, bypass valve is communicated with circuit pipe assembly again, formed and form annular air channel by circuit pipe assembly, gas compressor, intercooler, pressure stabilizing cavity and bypass valve, solve the problems such as equipment cost is high, internal combustion engine environment bad adaptability, effectively avoid tourist bus phenomenon simultaneously.
For achieving the above object, the concrete technological scheme that the present invention adopts is as follows:
A kind of charge inter cooling air-intake of combustion engine by-pass governing device, the straight tee comprising air filter and be connected in turn with air filter, circuit pipe assembly, gas compressor, intercooler, pressure stabilizing cavity, closure, cylinder of internal-combustion engine tunnel tube, described pressure stabilizing cavity is also communicated with bypass valve by Circulation pipe, and described bypass valve is communicated with circuit pipe assembly.
By above-mentioned design, inflammable mixture enters cylinder through circuit pipe assembly, gas compressor, intercooler, pressure stabilizing cavity, closure and cylinder of internal-combustion engine tunnel tube, period, inflammable mixture can also circulate by forming annular air channel by circuit pipe assembly, gas compressor, intercooler, pressure stabilizing cavity and bypass valve, the Throughput of recycle gas is controlled by bypass valve, thus reaches the size controlling to enter the tolerance of closure.
Further describe, described straight tee comprises the outlet of air inlet, fuel gas inlet and inflammable mixture, described air inlet communicates with ambient air, and described fuel gas inlet passes into combustion gas, and described inflammable mixture outlet is communicated with the suction port of described circuit pipe assembly.
Further describe, described bypass valve is integral type air throttle again
Beneficial effect of the present invention: bypass valve manufacture is simple, volume is little, flow through the gas temperature of pressure stabilizing cavity lower than 45 degree, thus it is low to the high temperature resistance characteristic requirements of bypass valve, thus significantly reduce equipment cost, the restriction characteristic of bypass valve valve block can make the Power operation scope of internal-combustion engine significantly promote, when change bypass valve aperture, the flexibility ratio of unit operation is increased, environmental adaptation degree is high, air inlet By-pass control system only gathers closure pressure difference signal, systems axiol-ogy closure pressure reduction is controlled during operation, large bypass valve is driven when pressure reduction exceedes setting pressure difference, when pressure reduction drives little bypass valve lower than during setting pressure difference, lower than during 50% load for ensureing air-intake of combustion engine amount, bypass valve can be closed and do not carry out air inlet bypass, this the air inlet bypass system gathering closure pressure difference signal can effectively avoid tourist bus phenomenon.
