Abstract
The utility model relates to a simple waste-gas recycling system used for an engine, which is characterized by comprising a waste gas communication pipe connected with an exhaust manifold of the engine; the other end of the waste gas communication pipe is connected with a flux adjusting plate that is connected with a cooler by the waste gas communication pipe; the cooler is connected with a check valve by the waste gas communication pipe; and the check valve is connected with an air inlet pipe of the engine by the waste gas communication pipe. In the utility model, the high-temperature and high-pressure waste gas of the engine is guided into the engine for re-utilization by the structure, therefore, the resource is saved and the emission is reduced, wherein the check valve is used for preventing the waste gas from flowing back; the cooler is used for reducing the temperature of the guided-in waste gas; and the flux adjusting hole plate is used for adjusting the flux of the guided-in waste gas; therefore, the waste gas guided in the engine is exactly controlled, the higher emission requirement is met, and the production cost and use cost are lower.
Description
Technical field
The utility model belongs to gas flow control system on the motor, particularly relates to a kind of simple and easy gas recirculation system that is used on the motor.
Background technique
At present, along with the develop rapidly of motor industry, the increasingly stringent of emission standard, the device that is installed on the engine intake and exhaust system is more and more, the engine development cost constantly increases, and further reduces the NOx discharging for realizing state four or requirements at the higher level engine emission.A large amount of EGR (exhaust gas recirculation) systems that adopt when the satisfied higher reduction NOx discharging of exploitation product of numerous motor producer for the accurate control of realization EGR gas flow, have extensively adopted electric control EGR (exhaust gas recirculation) system simultaneously.Practice shows, adopts electric control EGR (exhaust gas recirculation) system, will have to increase the motor cost, also very inconvenience in assembly process simultaneously, increase machining period, reduced efficiency, also have in addition and detect and maintenance is inconvenient to dismantle, system complex causes deficiencies such as rate of fault increase.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of simple in structure, reliable performance, detection easy to maintenance be used for simple and easy gas recirculation system on the motor.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of simple and easy gas recirculation system that is used on the motor, it is characterized in that: this gas recirculation system comprises the waste gas connecting tube that is connected with enmgine exhaust, the other end connection traffic regulator plate of waste gas connecting tube, flow control board connects cooler by waste gas connecting tube, cooler connects one-way valve by waste gas connecting tube, and one-way valve connects engine air inlet tube by waste gas connecting tube.
The utility model can also adopt following technical measures:
Described one-way valve comprises the valve block of unidirectional valve seat and control gaseous one-way flow, the valve gap that valve block is installed in the unidirectional valve seat by running shaft and is installed in the valve block outside.
Described flow control board comprises circular plate body, is provided with a taper or cylindrical hole on the plate body at least.
Advantage and the good effect that the utlity model has are: because the utility model is adopting technique scheme, promptly between the gas exhaust manifold of motor and suction tude, add the utility model structure, like this engine high-temperature high pressure exhaust gas being imported motor by the utility model utilizes once more, so not only save resource, and reduce discharging.One-way valve is used to prevent that waste gas from flowing backwards in the utility model in addition, cooler is used to reduce the exhaust gas temperature of importing, and flow control board is used to regulate the exhaust gas flow of importing, thereby realize importing the accurate control of engine exhaust, satisfy more maximum discharge requirement, and cost of production and user cost are lower.
