Detailed Description
Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used only to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
To keep the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known parts of the invention has been omitted.
As shown in fig. 1, a fuel evaporation control device of a general gasoline engine comprises an oil tank 1 and an oil nozzle 6 connected with the oil tank 1; the device also comprises a dump valve 7, a first air pipe 2, a carbon tank 3, a negative pressure switch 4, a throttle valve 5, a second air pipe 8, a third air pipe 9 and a fourth air pipe 10; the dump valve 7 is embedded at the top of the oil tank 1 in a sealing manner, an air inlet of the dump valve 7 is communicated with the inside of the oil tank 1, one end of the first air pipe 2 is connected with an air outlet of the dump valve 7, the other end of the first air pipe 2 is connected with an air inlet of the carbon tank 3, one end of the second air pipe 8 is connected with one air outlet of the carbon tank 3, the other end of the second air pipe 8 is connected with one air inlet of the negative pressure switch 4, one end of the third air pipe 9 is connected with an air outlet of the throttle valve 5, and the other end of the third air pipe 9 is connected with the other air inlet of the negative pressure switch 4; one end of a fourth air pipe 10 is connected to the air inlet of the throttle valve 5, and the other end of the fourth air pipe 10 is connected to the air outlet of the negative pressure switch 4; the oil outlet of the throttle valve 5 is connected with an oil nozzle 6.
An air filter 11 is also arranged on the air inlet of the throttle valve 5.
The working principle is as follows: when the engine works, the throttle valve 5 inputs internal oil gas into the oil nozzle 6 and simultaneously applies a suction force to the negative pressure switch 4 to open the negative pressure switch 4, so that the second air pipe 8 and the fourth air pipe 10 are communicated with each other, and therefore gas evaporated to the top of the oil tank 1 enters the carbon tank 3 through the dump valve 7 and the first air pipe 2, then enters the throttle valve 5 through the second air pipe 8, the negative pressure switch 4 and the fourth air pipe 10 and finally is sent into the oil nozzle 6; the dump valve 7 can prevent gasoline leakage of the oil tank 1 in a dumping state, and the carbon tank 3 can enable volatilized gasoline to reenter a gasoline conveying channel for utilization through the negative pressure switch 4 when the engine works; the canister 3 can adsorb the volatilized gasoline to prevent the escape when the engine does not operate.
The utility model discloses can adsorb the petrol that volatilizees from oil tank 1 and live or send into it in order to participate in the burning in the engine, and then thoroughly avoid volatilizing petrol to escape in the air to both prevented the waste of petrol, solved air pollution's problem again.
