Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

The following describes in detail a specific embodiment of the present invention with reference to the drawings. In the drawings, the same reference numerals indicate the same or corresponding features. The figures are only schematic and are not necessarily drawn to scale.

Referring to fig. 1 and 2, a novel engine suitable for various fuels is shown, including: the engine combustion chamber 1, the Venturi tube 2, the oil supply pipe 3, the oil tank 4, the oil delivery pipe 5, the adjustable nozzle 6, the oil spray shower head 7, the cone net 8, the cone head 9 and the screw rod 10, one end of the oil delivery pipe 5 penetrates through the throat position of the Venturi tube 2 and is in sealing connection with the penetration position, the other end of the oil delivery pipe 5 extends into the oil tank, the end part of the oil delivery pipe 5 positioned inside the Venturi tube 2 is connected with the adjustable nozzle 6, the bottom of the Venturi tube 2 is connected with the oil supply pipes 3 used for conveying oil-gas mixtures, the end part of the oil supply pipe 3 far away from the Venturi tube 2 is connected to the engine combustion chamber 1, the adjustable nozzle 6 comprises the oil spray shower head 7, the cone net 8, the cone head 9 and the screw rod 10, the cone net 8 and the oil spray shower head 7 are fixedly arranged at the end part of the oil delivery pipe 5, the cone net 8 is positioned inside the oil spray shower head 7, a plurality of jet holes are formed in the bottom of the oil spray shower head 7, the cone head 9 is arranged at the top of the cone net 8, the conical surface of the bottom of the conical head 9 is parallel to the conical surface of the conical net 8, the screw 10 penetrates through the top wall of the oil conveying pipe 5, the screw 10 is rotatably connected with the oil conveying pipe 5, the bottom end of the screw 10 is fixedly connected with the top end of the conical head 9, and a gap is reserved between the conical head 9 and the conical net 8.
