Description

Technical Field

[0001] The utility model relates to the technical field of gas injection rails, in particular to an efficient energy-saving gas injection rail device for automobiles. Background Technique

[0002] The gas injection rail is an essential component in gas-powered vehicles, responsible for providing fuel to the engine. It injects gas into the cylinder, mixes it with air, and then burns to generate power to drive the vehicle. The gas injection rail mainly consists of a rail body, solenoid valves, and injection groups.

[0003] During the use of existing automotive gas nozzles, when used in winter, due to the low temperature, the temperature of the gas introduced into the injection rail is low, and thus the temperature is also low when it is injected into the cylinder by the injection rail, which will affect the combustion efficiency of the gas. It does not have the function of preheating the injection rail and the gas, affecting the use effect. Therefore, we propose an efficient energy-saving gas injection rail device for automobiles.

The liquid pump is used to introduce the water with a certain temperature in the water tank during vehicle operation into the cavity of the hollow rail body, and then recycle it after passing through the two cavities, so as to realize the preheating of the gas in the hollow rail body, improve the gas fluidity, and then improve the effect of the gas injected into the cylinder. At the same time, the high efficiency of gas combustion is ensured, and the gas itself is used for preheating, thus achieving an energy-saving effect. In addition, the water pumped by the liquid pump will pass through the filter box for filtration to avoid impurities from affecting the liquid pump and the hollow rail body, playing a protective role.

[0008] As a preferred embodiment of the present utility model, a strip-shaped groove is provided on the inner side wall of the inner cavity of the cavity. The number of the strip-shaped grooves is multiple, and the multiple strip-shaped grooves are uniformly distributed along the length direction of the cavity.

[0009] By adopting the above technical solution, a plurality of uniformly distributed strip-shaped grooves are provided on the inner wall of the cavity, so as to increase the contact surface when hot water passes through, and thus the preheating effect can be further improved.

[0010] As a preferred embodiment of the present utility model, a filter mesh plate is fixed in the inner cavity of the filter box.

[0029] See also Figures 1-3 The utility model provides a technical solution: an efficient and energy-saving automobile gas rail spray device, comprising a hollow rail body 1, a plurality of evenly distributed electromagnetic valves 12 are fixed through the top of the hollow rail body 1, and a nozzle 11 is threadedly fixed at the bottom of the hollow rail body 1 corresponding to the electromagnetic valve 12;

[0030] A through cavity 14 is provided on both sides of one side wall of the hollow rail body 1, and end plates 16 are fixed to both ends of the cavity 14 by bolts. An inlet pipe 22 and an outlet pipe 17 are fixedly connected to the two end plates 16 at one end of the hollow rail body 1, and the outer end of the inlet pipe 22 is fixedly connected to a liquid pump 2, and the outer end of the liquid pump 2 is fixedly connected to a filter box 21 through a conduit 23, and the outer end of the filter box 21 is connected to a water pumping pipe. A fixed pipe 15 is arranged on the top of one end of the hollow rail body 1, and the two ends of the fixed pipe 15 are respectively connected to the two cavities 14.

[0031] During actual use, the outer end of the water suction pipe is connected to the water tank of the vehicle. Thus, during the operation of the vehicle, the water tank will heat up, and the water in the water tank will have a certain temperature. The liquid pump 2 is used to introduce the water with a certain temperature in the water tank during the operation of the vehicle into the cavity 14 of the hollow rail 1, and then recycle it after passing through the two cavities 14. Thus, it is possible to preheat the gas in the hollow rail 1, thereby improving the gas fluidity, further enhancing the effect of the gas injected into the cylinder, and at the same time ensuring the high efficiency of gas combustion. Moreover, the gas is preheated using its own heat, thus achieving an energy-saving effect. In addition, the water pumped by the liquid pump 2 will pass through the filter box 21 for filtration to prevent impurities from affecting the liquid pump 2 and the hollow rail 1, playing a protective role.

[0032] Furthermore, one end of the hollow rail 1 is fixedly connected to a connecting pipe 13. The setting of the connecting pipe 13 makes it convenient to connect to the pipeline providing gas.

[0033] Even further, an adapted rubber pad is fixedly installed on the inner side wall of the end plate 16. The setting of the rubber pad enables the end plate 16 to press the rubber pad tightly, ensuring the sealing performance and preventing water from overflowing.

[0034] It is worth introducing that a filter screen plate 24 is fixed in the inner cavity of the filter box 21. The setting of the filter screen plate 24 can filter out the impurities in the water introduced into the filter box 21.

[0035] It should be noted that the solenoid valve 12 and the corresponding nozzle 11 are arranged opposite to each other, so as to ensure that the solenoid valve 12 can accurately block and release the nozzle 11.

[0036] As Figure 1 and 2 shown; strip-shaped grooves 18 are formed on the inner side wall of the inner cavity of the cavity 14. The number of the strip-shaped grooves 18 is multiple, and the multiple strip-shaped grooves 18 are evenly distributed along the length direction of the cavity 14. By providing multiple evenly distributed strip-shaped grooves 18 on the inner wall of the cavity 14, the contact area can be increased when hot water passes through, thereby further improving the preheating effect.

[0037] The implementation principle of an efficient energy-saving automotive gas injection rail device in this application is as follows: During actual use, the outer end of the water suction pipe is connected to the water tank of the vehicle. As a result, the water tank will heat up during vehicle operation, and the water in the tank will reach a certain temperature. The liquid pump 2 is used to introduce the water with a certain temperature in the water tank during vehicle operation into the cavity 14 of the hollow rail body 1, and then recycle it after passing through the two side cavities 14. This can achieve preheating of the gas in the hollow rail body 1, thereby improving the gas fluidity, further enhancing the effect of the gas injected into the cylinder, ensuring the high efficiency of gas combustion, and achieving an energy-saving effect by using the heat of the gas itself. Moreover, the water pumped by the liquid pump 2 will pass through the filter box 21 for filtration to prevent impurities from affecting the liquid pump 2 and the hollow rail body 1, playing a protective role. Additionally, when the hot water passes through, the contact area is increased, which can further improve the preheating effect.

Their structures and principles can be learned by those skilled in the art through technical manuals or by conventional experimental methods.

For the specific connection means, reference should be made to the sequence of operation of each electrical component in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of electrical control will be given.
