Description
Technical field
The utility model belongs to gaseous fuel Collection utilization technical field, and in particular to a kind of internal combustion engine pressure regulating system
Gas collection processing system.
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.
Utility model content
In order to make up for the defects of the prior art, the utility model provides one kind, and the gas of prior art defect have been overcome to receive
Collect processing system.
The utility model is achieved by the following technical solution:
A kind of gas collection processing system, including pressure regulating system, gas collection tank and ECU electronic control unit, institute
It states the pipeline that gas collection tank is connected to inlet manifold and is equipped with switch valve, gas collection tank is equipped with pressure sensor, pressure
Sensor and switch valve pass through ECU electronic control unit respectively and are controlled, and the gas collection tank and pressure regulating system connect
The pipeline connect is equipped with check valve.
The beneficial effects of the utility model are:
(1) pressure release gaseous fuel can be collected, handle by the utility model, avoid directly arranging into atmosphere, cause
Pollution and other harm；
(2) fuel availability of gaseous fuel can be improved in the utility model；
(3) the utility model has filled up the blank in the world in pressure release gas collection, processing scheme；
(4) the utility model has given full play to the spatter property of dual fuel injection system, has greatly pushed diesel gas
The technological progress and mass process of dual fuel injection system internal combustion engine.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Attached drawing 1 is the catenation principle schematic diagram of the utility model.
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 utility model.A kind of gas collection processing system of the utility model, including
Pressure regulating system 1, gas collection tank 3 and ECU electronic control unit 6, what the gas collection tank 3 was connected to inlet manifold 7
Pipeline is equipped with switch valve 5, and gas collection tank 3 is equipped with pressure sensor 4, and pressure sensor 4 and switch valve 5 pass through respectively
ECU electronic control unit 6 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 in pressure regulating system are equipped in a kind of gas collection processing system of the utility model
When pressure is more than the setting pressure of spring, check valve 2 is opened, in pressure release gas flow gas collection tank 3, when gas collection tank 3
In gas pressure and spring force resultant force be greater than pressure release gas pressure when, check valve 2 close, the reflux of gas can be prevented,
Gas collection tank is equipped with pressure sensor 4 simultaneously, and pressure sensor 4 is by the pressure signal transmission in gas collection tank 3 to ECU
Electronic control unit 6, when gas pressure is more than the pressure value of setting, ECU electronic control unit 6 is according to the work work of engine
Condition sends switching signal, instruction of the switch valve 5 according to ECU 6, the quantitative conveying gas combustion into inlet manifold 7 to switch valve 5
Material, gaseous fuel can play certain gaseous fuel enriching effect, gas after entering inlet manifold 7 to the burning of engine
Enriching need to control in the range of setting, so that the explosion pressure of engine, discharges the controls such as parameter in allowed limits, when
When gas pressure in gas collection tank 3 is less than setting value, signal is passed to ECU 6 by pressure sensor 4, and the transmission of ECU 6 refers to
It enables to switch valve 5, switch valve 5 is closed.
The utility model is not limited to above embodiment, anyone, which should learn, makes under the enlightenment of the utility model
There is same or similar technical solution with the utility model, each fall within the protection scope of the utility model.
Technology that the utility model is not described in detail, shape, construction portion are well-known technique.
