[0001] The present invention relates to the technical field of motorcycles, and in particular to a device and method for improving the fuel saving and emission reduction performance of motorcycles. Background Art

[0002] With the progress of the times, the number and types of motorcycles are increasing, and the motorcycle engine is the heart of the motorcycle. The motorcycle engine is a thermal internal combustion engine that converts the chemical energy of fuel into mechanical energy. The mainstream fuel is gasoline (accounting for more than 95%). It has the characteristics of light weight, low vibration and high power density and has become the core power unit of the motorcycle.

[0003] When a motorcycle is running, as the engine's power frequency increases, its main shaft speed increases. The existing technology cannot adjust the engine intake pipe pressure according to the speed, which can easily lead to an increase in the engine's intake volume when running at high speeds, and a waste of 15 to 20 percent of the pumping air volume, resulting in incomplete fuel combustion and waste, as well as serious carbon deposits on the spark plugs. Summary of the Invention

[0004] The technical solution of the present invention addresses the technical problem that the existing technical solutions are too single, and provides a solution that is significantly different from the existing technology. Specifically, the purpose of the present invention is to provide a device and method for improving the fuel energy saving and emission reduction performance of motorcycles to solve the problems raised in the above background technology.

[0009] Preferably, the two switching assemblies each include a hollow tube, a conical sleeve and two half-augers, the hollow tube sleeve is arranged inside the air intake pipe, the conical sleeve is fixedly arranged at the end of the hollow tube, and the two half-augers are slidably connected to the inner wall of the air intake pipe.

[0010] Preferably, the end of the semi-auger is provided with a conical surface, and the end of the semi-auger is in contact with the inner wall of the conical sleeve.

[0011] Preferably, the adjustment mechanism includes a second wedge rod, two U-shaped frames, two adjustment springs, four semicircular seats and a third wedge rod. The first wedge rod is fixedly arranged on the top of the L-shaped wedge rod, and the four semicircular seats are movably connected in pairs on the top of the engine body.

[0012] A method for improving the fuel saving and emission reduction performance of a motorcycle comprises the following steps:

[0013] S1: When the main shaft speed reaches 10,000 rpm while the motorcycle is running, the main shaft drives the judgment mechanism to rotate, and the judgment mechanism conflicts with the switching mechanism under the action of centrifugal force;

[0014] S2: After the switching mechanism encounters resistance, the switching mechanism switches to a spiral channel shape inside the intake pipe, so that the intake pipe enters the combustion chamber along the spiral channel;

[0015] S3: By judging that the mechanism moves under the action of centrifugal force, the regulating mechanism is driven to work synchronously, and the regulating mechanism moves downward, reducing the volume of the combustion chamber and increasing the internal pressure of the combustion chamber.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention realizes automatic determination of the main shaft speed by setting the first spring, wedge block, fixed shaft, connecting rod and sliding ring, and adaptively adjusts different intake modes according to the speed of the motorcycle, ensuring that the engine body can ensure sufficient combustion of fuel in both low and high speed gears, with strong applicability and no need for adjustment;

During the intake of air, the centrifugal force generated by the spiral airflow increases the radial diffusion speed of the fuel particles by 20%, thereby increasing the oil-gas mixing process, effectively reducing carbon emissions, and saving energy and protecting the environment.

[0019] (3) The present invention realizes adaptive reduction of the combustion chamber volume under high-speed driving by providing a second wedge-shaped rod, two U-shaped frames, two adjustment springs, four semicircular seats and a third wedge-shaped rod, thereby increasing the internal compression ratio, improving the combustion rate and effectively improving the torque output.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6 The present invention provides an embodiment: a device for improving the fuel energy saving and emission reduction performance of a motorcycle, comprising an engine body 1, a main shaft 2 being rotatably provided on the side wall of the engine body 1, two intake pipes 9 being provided on the top of the engine body 1, two intake plugs 8 being provided on the top of the engine body 1, a protective shell 3 being fixedly provided on the side wall of the engine body 1, a judgment mechanism 4 for judging the rotation speed of the main shaft 2 being fixedly provided on the side wall of the output shaft, an adjustment mechanism 7 being provided on the top of the engine body 1, a switching mechanism 5 being provided inside the two intake pipes 9, and two spark plugs 6 being screwed on the top of the engine body 1.

[0029] Specifically, the judgment mechanism 4 includes a first spring 41, a wedge block 42, a fixed shaft 43, a connecting rod 44, and a sliding ring 45. The sliding ring 45 is slidingly set on the inner side wall of the protective shell 3. The fixed shaft 43 is fixedly set on the main shaft 2, and the wedge block 42 is slidingly sleeved on the connecting rod 44. The two ends of the first spring 41 are respectively fixed on the main shaft 2 and the wedge block 42, and the connecting rod 44 is fixed on the sliding ring 45. The rotation of the main shaft 2 drives the fixed shaft 43 and the wedge block 42 to rotate synchronously. When the speed reaches 10,000 rpm, the wedge block 42 stretches the first spring 41, synchronously abutting the sliding ring 45. The movement of the sliding ring 45 drives the connecting rod 44 to move synchronously. The automatic judgment of the main shaft 2 speed is achieved, and different intake methods are adaptively adjusted according to the speed of the motorcycle. This ensures that the engine body 1 can ensure sufficient combustion of fuel in both low and high speed gears. It has strong applicability and does not require adjustment.

[0030] Specifically, the inner wall of the sliding ring 45 is provided with a tapered surface, and the tapered surface is in contact with the wedge block 42 .

[0031] Specifically, the switching mechanism 5 includes an L-shaped wedge rod 51, a U-shaped rod 52, a first wedge rod 57, a return spring 54 and two switching components. The L-shaped wedge rod 51 is fixedly set on the top of the connecting rod 44, one end of the U-shaped rod 52 is fixedly set on the bottom of the L-shaped wedge rod 51, and the first wedge rod 57 is fixedly set on the other end of the U-shaped rod 52. The two switching components are respectively arranged inside the two intake pipes 9, and the return spring 54 is fixedly set on the top of the engine body 1.

[0032] Specifically, the two switching assemblies each include a hollow tube 53, a tapered sleeve 55, and two half-auger assemblies 56. The hollow tube 53 is sleeved within the intake pipe 9. The tapered sleeve 55 is fixedly mounted at the end of the hollow tube 53. The two half-auger assemblies 56 are slidably engaged with the inner sidewall of the intake pipe 9. The movement of the connecting rod 44 drives the L-shaped wedge rod 51, the U-shaped rod 52, and the first wedge rod 57 to move synchronously. The L-shaped wedge rod 51 and the first wedge rod 57 simultaneously abut against the tapered sleeve 55, causing the tapered sleeve 55 to drive the hollow tube 53 toward the intake plug 8. The tapered sleeve 55 abuts against the tapered surfaces at the ends of the half-auger assemblies 56, causing the two half-auger assemblies 56 to merge, forming a spiral air duct within the intake pipe 9. This enables automatic switching of the spiral air duct when the motorcycle is traveling at high speed. During intake, the centrifugal force generated by the spiral airflow increases the radial diffusion velocity of fuel particles by 20%, accelerating the oil-gas mixing process, effectively reducing carbon emissions, and saving energy and protecting the environment.

[0033] Specifically, the end of the semi-auger is provided with a conical surface 561 , and the end of the semi-auger 56 is in contact with the inner wall of the conical sleeve 55 .

[0034] Specifically, the adjustment mechanism 7 includes a second wedge rod 71, two U-shaped frames 72, two adjustment springs 73, four semicircular seats 74, and a third wedge rod 75. The first wedge rod 57 is fixedly mounted on the top of the L-shaped wedge rod 51. The four semicircular seats 74 are movably connected in pairs on the top of the engine body 1. The two U-shaped frames 72 are fixedly mounted on the tops of the four semi-cylinders. The two adjustment springs 73 are fixedly mounted on the bottoms of the U-shaped frames 72. The third wedge rod 75 is fixedly mounted on the tops of the two U-shaped frames 72. The second wedge rod 71 abuts against the third wedge rod 75. The movement of the connecting rod 44 drives the second wedge rod 71 to move. The second wedge rod 71 moves against the third wedge rod 75, which moves downward. The downward movement of the third wedge rod 75 drives the semicircular seats 74 downward, causing the semicircular seats 74 to insert into the combustion chamber, thereby reducing the combustion chamber volume. This achieves adaptive reduction of the combustion chamber volume during high-speed driving, thereby increasing the internal compression ratio, improving the combustion rate, and effectively improving torque output.

[0035] A method for improving the fuel saving and emission reduction performance of a motorcycle comprises the following steps:

[0036] S1: When the main shaft 2 rotates at 10,000 rpm while the motorcycle is running, the main shaft 2 drives the judgment mechanism 4 to rotate, and the judgment mechanism 4 contacts the switching mechanism 5 under the action of centrifugal force;

[0037] S2: After the switching mechanism 5 encounters resistance, the switching mechanism 5 switches to a spiral channel shape inside the intake pipe 9, so that the intake pipe 9 enters the combustion chamber along the spiral channel;

[0038] S3: By judging that the mechanism 4 moves under the action of centrifugal force, the regulating mechanism 7 is driven to work synchronously, and the regulating mechanism 7 moves downward, reducing the volume of the combustion chamber and increasing the internal pressure of the combustion chamber.

[0039] Working principle: When the motorcycle is running, the main shaft 2 rotates to drive the fixed shaft 43 wedge block 42 to rotate synchronously. When the speed reaches 10,000 At rpm, the wedge block 42 stretches the first spring 41, synchronously contacting the sliding ring 45, and the movement of the sliding ring 45 drives the connecting rod 44 to move synchronously. The movement of the connecting rod 44 drives the L-shaped wedge rod 51, the U-shaped rod 52 and the first wedge rod 57 to move synchronously. The L-shaped wedge rod 51 and the first wedge rod 57 synchronously contact the conical sleeve 55, so that the conical sleeve 55 drives the hollow tube 53 to move toward the intake plug 8. The conical sleeve 55 contacts the conical surface at the end of the semi-auger 56, so that the two semi-auger 56 are merged, so that a spiral air duct is formed inside the intake pipe 9. The second wedge rod 71 is driven to move by the movement of the connecting rod 44. The second wedge rod 71 moves and contacts the third wedge rod 75 downward. The downward movement of the third wedge rod 75 drives the semicircular seat 74 downward, so that the semicircular seat 74 is inserted into the combustion chamber, thereby reducing the volume of the combustion chamber and increasing the air pressure inside the combustion chamber.

[0040] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
