[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1-4 As shown in the embodiment, a multi-functional gas engine intake pipe is provided, including an intake manifold 1, a gasoline injection component 2, a gas injection component 3, and a guide pipe 4. Gasoline injection channels 11 and gas injection channels 12 are respectively provided on both sides of the intake manifold 1. The gasoline injection component 2 is connected to the gasoline injection channel 11, and the gas injection component 3 is connected to the gas injection channel 12. The guide pipe 4 is disposed inside the intake manifold 1, and one end of the guide pipe 4 is connected to the output end of the gas injection component 3. In this embodiment, there are two or more gasoline injection channels 11 and gas injection channels 12. Both the gasoline injection component 2 and the gas injection component 3 are existing technologies. The gasoline injection component 2 includes a gasoline guide rail for conveying gasoline and gasoline injectors disposed on the gasoline guide rail. Gasoline nozzles connected to gasoline injection channels 11 are disposed on the gasoline guide rail, and the number of gasoline nozzles is equal to and corresponds one-to-one with the number of gasoline injection channels 11, thereby achieving the injection of gasoline into the intake manifold 1. The gas injection component 3 includes a gas guide rail for conveying gas and gas injectors disposed on the gas guide rail. Gas nozzles are disposed on the gas guide rail, and the number of gas nozzles is equal to and corresponds one-to-one with the number of gas injection channels 12, thereby achieving the injection of gas into the intake manifold 1. Furthermore, the included guide pipe 4 improves the uniformity of air intake. In addition, all components used in this embodiment are commercially available.

[0017] Specifically, such as Figure 1As shown, the gasoline injection component 2 and the gas injection component 3 are located on both sides of the intake manifold 1, respectively. In this embodiment, the intake function of the dual-fuel system is realized by arranging the gasoline injection component 2 and the gas injection component 3 on both sides of the intake manifold 1.

[0018] Specifically, such as Figure 1 As shown, a water outlet pipe 5 is also provided at the bottom of the intake manifold 1. In this embodiment, coolant flows through the water outlet pipe 5 to cool the gas in the intake manifold 1, thereby reducing the engine intake air temperature and improving the air exchange efficiency.

[0019] Specifically, such as Figure 1 As shown, a thermostat 6 is connected to the water outlet pipe 5. In this embodiment, the thermostat 6 is used to cool the coolant in the water outlet pipe 5, thereby improving the cooling effect.

[0020] Specifically, such as Figure 4 As shown, both the gasoline injection channel 11 and the gas injection channel 12 are arranged at an angle.

[0021] Specifically, such as Figure 4 As shown, the other end of the guide pipe 4 has a bevel. In this embodiment, the bevel is opposite to the intake direction of the intake manifold 1, which reduces the impact of airflow on the combustion gas and prevents the combustion gas from flowing back into the guide pipe 4. The bevel angle is preferably 45°, which allows the combustion gas to form a strong impact on the airflow, which is beneficial to the mixing of combustion gas and air, and makes the engine work more smoothly.

[0022] This utility model has been described through preferred embodiments. Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model.
