Abstract
Description
Technical Field
[0001] The present application relates to the technical field of engine supercharging, and in particular to an engine supercharging system. Background Art
[0002] In recent years, my country's motorcycle market has experienced significant growth, with mid-displacement multi-cylinder motorcycles becoming a hot commodity. For motorcycles, the engine determines many aspects of the vehicle's performance, such as power and environmental friendliness. Both domestic and foreign brands primarily offer naturally aspirated engines. Only a few models from foreign brands feature non-naturally aspirated intake systems, such as the Suzuki Hayabusa, which uses a turbocharger. However, turbocharging is not ideal for the power output of small and mid-displacement engines, and turbocharging can easily lead to turbo lag and other issues. Furthermore, while naturally aspirated engines offer a simple design and high fuel efficiency, their inherent nature of generating negative pressure for intake can lead to incomplete combustion and substandard emissions. To meet emission standards, all manufacturers are forced to strengthen their research on exhaust three-way catalytic converters to ensure that engine emissions meet national standards. Furthermore, the lower oxygen content in the air in plateau regions results in incomplete combustion, resulting in a loss of power. This is also the reason many motorcycles stall when driving in high altitude areas. Therefore, in order to solve the above problems, the present application provides an engine boosting system.
[0003] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content
[0004] In order to solve the problems of incomplete combustion, substandard emissions and flameout caused by the intake structure of existing motorcycle engines, the present application provides an engine boosting system.
[0005] The present application provides an engine supercharging system, comprising an engine body, characterized in that: a small pulley is coaxially mounted on the engine magneto rotor;
[0006] The boosting system includes a mechanical supercharger, which is connected to a small pulley via a belt drive. The output end of the mechanical supercharger is sequentially connected to an intake system pipeline, a cooler, and a pressure stabilizing chamber for pressurizing, cooling, and stabilizing the air. The pressure stabilizing chamber is connected to the intake end of the engine.
[0007] The operation of the mechanical supercharger is achieved through a belt and a small pulley. The mechanical supercharger transports air, which is pressurized in the intake system pipeline, cooled in the cooler, and finally reaches a stable pressure state in the pressure stabilizing chamber, thereby transporting air to the engine, increasing the air input, and promoting the complete combustion reaction.
[0008] Preferably, the supercharger is a centrifugal supercharger.
[0009] Preferably, the engine magneto rotor is coaxially fixedly connected to a transmission shaft, and the small pulley is fixedly mounted on the transmission shaft.
[0010] Preferably, a flange for fixing the position of the transmission shaft is fixedly connected to the outer wall of the engine by bolts.
[0011] Preferably, an air intake filter is provided at the input end of the mechanical supercharger.
[0012] Preferably, the air intake system pipeline is installed with a pressure relief valve.
[0013] Preferably, a throttle valve is provided at the position where the pressure stabilizing chamber is connected to the engine.
[0014] Preferably, the pressure stabilizing chamber is in a circular tubular structure, and its diameter is larger than the intake system pipeline.
[0015] In summary, this application has the following beneficial technical effects:
[0016] Through the mutual cooperation of the intake system pipeline and the pressure stabilizing chamber, it not only completes the air transportation, but also has the function of storing air. Under the action of the pressure stabilizing chamber, the engine intake is more uniform, the resonance is reduced, and the intake efficiency is increased. Compared with the existing engine intake method, it has a higher intake volume and increases the stability of engine operation.
[0017] By adding a drive shaft to the engine magneto rotor, a transmission connection is established between the engine body and the mechanical supercharger, thereby realizing power transmission. In addition, the use of flanges increases the stability of the drive shaft rotation, ensuring the smooth operation of the supercharger.
[0018] The air is cooled by the cooler, which makes the intake quality higher. The intake system ensures safety under the action of the pressure relief valve. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following is combined with Figure 1 - Figure 4 This application is described in further detail.
[0025] Example 1:
[0026] Reference Figure 1 - Figure 4 An engine supercharging system includes a supercharger 1 drive shaft bolted to the engine magneto rotor. The drive shaft is mounted on the engine block via a connecting flange 4. The connecting flange 3 is bolted to the engine block. Flange 4 increases the coaxiality and concentricity between the magneto rotor and the drive shaft. Supercharger 1 generates power through the rotation of the engine crankshaft. Supercharger 1 utilizes a centrifugal structure, which enables the engine to obtain more intake air, increase power, and improve engine fuel economy. Furthermore, centrifugal supercharger 1 generates very little noise and eliminates some intake resonance, resulting in even less noise during engine operation and a more environmentally friendly engine. A small pulley 7 is mounted on the outside of drive shaft 3. A belt 9 is used to transmit power between small pulley 7 and supercharger 1, thereby generating power for centrifugal supercharger 1.
[0027] When the engine begins running, the supercharger 1 rotates under the action of belt 9, allowing external air to enter the centrifugal supercharger 1 through the intake filter 8. The air is then compressed by the centrifugal supercharger 1 and enters the intake system 6, which serves as both an air circulation channel and a storage container for the compressed air. The compressed air then enters the intercooler 10 for cooling. When the compressed air pressure reaches the set boost pressure, the pressure relief valve 5 opens to release excess pressure. The cooled air from the intercooler 10 enters the intake pressure-stabilizing chamber 2. After the pressure inside the pressure-stabilizing chamber 2 is stabilized, it is adjusted by the throttle 11 before entering the engine cylinder to combust with the fuel. After the engine compresses the air, the exhaust gas is discharged through the exhaust system and then through the muffler system into the atmosphere. This completes the entire operating cycle. As the engine continues to operate, more and more fresh air is discharged into the atmosphere after being used by the engine, providing a continuous and powerful engine power.
[0028] The supercharging system can be used not only as a power unit for motorcycles, but also as an air intake system for engines of go-karts, Formula Student racing cars, etc., thereby increasing the scope of application of the device.
[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
