Description
Technical field
The invention belongs to gaseous fuel Collection utilization technical fields, and in particular to a kind of gas of internal combustion engine pressure regulating system
Body collection processing system implementing.
Background technique
Currently marketed medium-weight vehicle mainly uses diesel oil as fuel, this kind of burning efficiency of internal combustion engine is substantially low
In 39%, with the publication of six discharge standard of state, high pressure direct injection natural gas in cylinder technology using diesel oil as single-fuel, i.e. high-pressure common rail
The matching cost and technical difficulty of system gradually increase, while also bringing the growth in cost.
With the adjustment of national energy structure, and the promotion to emission request, traditional with gasoline and diesel oil is burning
The internal combustion engine of medium will gradually decrease.Natural gas is abundant in china natural resources, gradually starts to be applied to as the alternative fuel of diesel oil
Automobile market.But current natural gas internal combustion engine is gas-duct jetting, is lighted by spark plug, efficiency of combustion is lower than
39%, and emission control has been difficult to meet the emission request of country's promulgation being increasingly stringenter.
A kind of in-cylinder direct-jet technology of achievable dual fuel injection can effectively improve burning by the way of compression ignition
Efficiency.The double fuel direct injection technology first sprays a small amount of diesel oil in the combustion chamber, after compression ignition, is promoted in combustion in IC engine room
Temperature, ignite the natural gas then sprayed, then carries out work by combustion.The technology, can by efficiency of combustion promoted to 42% with
On, and PM value and the discharge of NOx can be largely reduced, and more to clean, more economical fuel injection system for IC engine.
In above-mentioned double fuel in-cylinder direct-jet system, the pressure difference of natural gas and diesel oil accurately will be controlled quickly, need according to
Pressure regulating system by adjusting diesel pressure and gas fuel pressure.Pressure regulating system works under engine specific operation
When, it needs to carry out the pressure release of gas pressure by pressure release passage, at present in the world, has efficacious prescriptions there are no processing pressure release gas
Method can only be directly discharged in air.Discharges gas fuel will cause air pollution into air, if big in a small range
Amount gathers fuel gas, it is also possible to cause the burning of gas, or even explosion, harmfulness is very big, therefore is badly in need of developing a kind of collection
The system of collection, the processing of fuel gas.
Summary of the invention
In order to compensate for the shortcomings of the prior art, the present invention provides one kind to have overcome at the gas collection of prior art defect
Reason system.
The present invention is achieved through the following technical solutions:
A kind of gas collection processing system, including pressure regulating system, gas collection tank and ECU electronic control unit, the gas
The pipeline that body collecting tank is connected to inlet manifold is equipped with switch valve, and gas collection tank is equipped with pressure sensor, pressure sensing
Device and switch valve pass through ECU electronic control unit respectively and are controlled, what the gas collection tank was connect with pressure regulating system
Pipeline is equipped with check valve.
The beneficial effects of the present invention are:
(1) pressure release gaseous fuel can be collected, handle by the present invention, avoid directly arranging into atmosphere, pollute and its
He endangers；
(2) fuel availability of gaseous fuel can be improved in the present invention；
(3) present invention has filled up the blank in the world in pressure release gas collection, processing scheme；
(4) present invention has given full play to the spatter property of dual fuel injection system, and diesel gas double fuel has greatly been pushed to spray
Penetrate the technological progress and mass process of system internal combustion engine.
Detailed description of the invention
The present invention will be further described below with reference to the drawings.
Attached drawing 1 is catenation principle schematic diagram of the invention.
In figure, 1 pressure regulating system, 2 check valves, 3 gas collection tanks, 4 pressure sensors, 5 switch valves, 6 ECU electronics
Control unit, 7 inlet manifolds.
Specific embodiment
Attached drawing 1 is a kind of specific embodiment of the invention.A kind of gas collection processing system of the invention, including pressure are adjusted
System 1, gas collection tank 3 and ECU electronic control unit 6 are set on the pipeline that the gas collection tank 3 is connected to inlet manifold 7
There is switch valve 5, gas collection tank 3 is equipped with pressure sensor 4, and pressure sensor 4 and switch valve 5 pass through the control of ECU electronics respectively
Unit 6 processed is controlled, and the pipeline that the gas collection tank 3 is connect with pressure regulating system 1 is equipped with check valve 2.
Check valve 2, the pressure release gas pressure in pressure regulating system are equipped in a kind of gas collection processing system of the invention
More than spring setting pressure when, check valve 2 is opened, in pressure release gas flow gas collection tank 3, when in gas collection tank 3
When the resultant force of gas pressure and spring force is greater than the pressure of pressure release gas, check valve 2 is closed, and can prevent the reflux of gas, simultaneously
Gas collection tank is equipped with pressure sensor 4, and pressure sensor 4 gives the pressure signal transmission in gas collection tank 3 to ECU electronics
Control unit 6, when gas pressure is more than the pressure value of setting, ECU electronic control unit 6 according to the work operating condition of engine,
Switching signal is sent to switch valve 5, switch valve 5 quantitatively conveys gaseous fuel, gas according to the instruction of ECU 6 into inlet manifold 7
Fluid fuel can play certain gaseous fuel enriching effect after entering inlet manifold 7 to the burning of engine, and gas enriching needs
Control is in the range of setting, so that the explosion pressure of engine, discharges the controls such as parameter in allowed limits, when gas is received
When collecting the gas pressure in tank 3 less than setting value, signal is passed to ECU 6 by pressure sensor 4, and ECU 6 is sent instructions to out
Valve 5 is closed, switch valve 5 is closed.
The present invention is not limited to the above-described embodiments, anyone should learn make under the inspiration of the present invention with the present invention
With same or similar technical solution, fall within the scope of protection of the present invention.
Technology not described in detail in the present invention, shape, construction portion are well-known technique.
