Detailed Description

Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.

An all-terrain vehicle 100 according to an embodiment of the invention is described below with reference to fig. 1-5.

As shown in fig. 1-3, atv 100 includes: the engine 10 includes a cylinder having an intake port 11 and an exhaust port, that is, air can be introduced into the cylinder from the intake port 11, mixed with fuel and ignited, so that the engine 10 can generate power, and the combusted exhaust gas is discharged through the exhaust port, an air cleaner 34, and a supercharger 20. An air filter 34 is connected to the air intake 11, and the air filter 34 can filter air entering the engine 10 to prevent impurities in the air from affecting the overall normal use of the engine 10.

Also, as shown in fig. 4, the supercharger 20 is connected between the air cleaner 34 and the intake port 11 to send pressurized air into the cylinder through the intake port 11. That is, supercharger 20 increases the intake air amount of engine 10 by compressing air. The supercharger 20 can drive the impeller of the compressor 22 coaxial with the supercharger 20, and the impeller can press and feed air entering the supercharger 20, so that the air enters the cylinder through the air inlet 11 after being pressurized. The air pressure and density in the cylinder increases and the engine 10 can burn more fuel, which in turn increases the amount of fuel and adjusts the speed of the engine 10, which in turn increases the output of the engine 10.

In addition, when ATV 100 is used in a portion of high altitude areas, the air is leaner the higher the altitude, and engine 10 may draw more air through supercharger 20, which may overcome the power reduction of engine 10 due to lean high altitude air.

Specifically, as shown in fig. 1 to 3, the supercharger 20 is a turbocharger, and the supercharger 20 includes: the turbine 21 is in driving connection with the compressor 22, the turbine 21 is connected to the exhaust port, and the compressor 22 is connected between the air filter 34 and the air inlet 11. With such an arrangement, the inertia impulse of the exhaust gas discharged from the engine 10 pushes the turbine in the turbine 21, the turbine 21 drives the compressor 22 to rotate coaxially, and the impeller of the compressor 22 in the compressor 22 pumps the air sent from the air filter 34, so that the air is pressurized and enters the cylinder, thereby increasing the output power of the engine 10. When the rotation speed of the engine 10 is increased, the exhaust gas discharge speed and the turbine rotation speed are also increased synchronously, the compressor 22 compresses more air into the cylinder, the pressure and density of the air are increased, more fuel can be combusted, the fuel quantity is correspondingly increased, the rotation speed of the engine 10 is adjusted, and therefore the output power of the engine 10 can be increased.

Therefore, by arranging the supercharger 20 between the air filter 34 and the air inlet 11 of the engine 10, the air input of the engine 10 can be increased, so that the cylinder can burn more fuel, the fuel quantity is correspondingly increased, the rotating speed of the engine 10 is adjusted, the output power of the engine 10 can be increased, the combustion efficiency of the fuel is increased, and energy conservation and emission reduction are facilitated.

As shown in fig. 4, the turbine 21 further has an exhaust gas inlet 211, the exhaust gas inlet 211 is disposed opposite to the exhaust port, and the turbine 21 is provided with a flange 212 at the exhaust gas inlet 211, and the flange 212 is fixedly coupled to the exhaust port by a fastener. That is, the exhaust gas generated by the engine 10 enters the turbine 21 through the exhaust gas inlet 211 of the turbine 21, so that the turbine of the turbine 21 can be driven. And, the turbine 21 is provided with the flange 212 at the exhaust gas inlet 211, which can improve the intake stability of the turbine 21, thereby improving the working efficiency of the turbine 21 to some extent.

As shown in fig. 1 and 4, atv 100 further includes: an exhaust pipe 35 and a silencer 36, the turbine 21 has an exhaust outlet 213, the exhaust pipe 35 is connected with the exhaust outlet 213 and extends toward the rear, the silencer 36 is disposed at the exhaust pipe 35 and adjacent to the tail of the exhaust pipe 35, and the silencer 36 is located behind the air filter 34. With the arrangement, after the compressor 22 is driven by the turbine 21 to operate, the exhaust gas generated by the engine 10 enters the exhaust pipe 35 through the exhaust gas outlet 213, is finally silenced by the silencer 36 and is then discharged, so that the noise generated by the engine 10 can be reduced.

As shown in fig. 1, the intake port 11 and the exhaust port are disposed on opposite sides, e.g., front and rear sides, of the engine 10, the intake port 11 may be disposed on the rear side, and the exhaust port may be disposed on the front side. The supercharger 20 is disposed adjacent to the exhaust port as compared to the intake port 11, and the air filter 34 is disposed adjacent to the intake port 11 as compared to the exhaust port. With such an arrangement, the supercharger 20 is disposed adjacent to the exhaust port, so that the exhaust gas generated by the engine 10 can enter the supercharger 20 after being exhausted through the exhaust port, and the space of the all-terrain vehicle 100 can be reasonably arranged conveniently. Also, an air filter 34 is disposed adjacent to the air intake 11, and the air filter 34 absorbs fresh air and can facilitate the entry of air into the air filter 34.

Further, the supercharger 20 is located on the front side of the cylinder and is disposed adjacent to the top of the cylinder, and the air filter 34 is located above and behind the cylinder. With such an arrangement, the supercharger 20 can be conveniently connected with the exhaust port of the engine 10, the space at the front side of the cylinder can be reasonably utilized, the space at the rear upper part of the cylinder can be reasonably utilized, the arrangement of the air filter 34 is convenient, and the use space of the all-terrain vehicle 100 can be saved. Moreover, the air filter 34 is arranged at the rear upper part of the air cylinder, so that the height of the air filter 34 can be ensured, the risk of water inflow can be avoided, and air inflow can be facilitated.

As shown in fig. 1-4, atv 100 further includes: the intercooler 31, the intercooler 31 are connected between the compressor 22 and the intake port 11, and the intercooler 31 is disposed adjacent to the supercharger 20 as compared to the air filter 34. The exhaust gas generated by the engine 10 has a high temperature, and the exhaust gas temperature increases, which not only affects the charging efficiency of the engine 10, but also easily causes knocking in the cylinder. The air taken into the cylinders is cooled by providing an intercooler 31 and being installed between the supercharger 20 and the intake port 11. Thus, the intercooler 31 can not only keep the compression ratio of the engine 10 at a certain value without causing knocking, but also lower the temperature to increase the intake pressure, thereby further increasing the effective power of the engine 10. Also, by disposing intercooler 31 adjacent to supercharger 20, the piping between the two may be shortened, or the piping between the two may be omitted directly, so that atv 100 may be made more compact.

As shown in fig. 1, the intercooler 31 is located above the supercharger 20, and the intercooler 31 is also located in front of the air filter 34. So set up, intercooler 31 can conveniently cool down the interior air that enters into booster 20 to can rationally arrange and distribute atv 100's space. Furthermore, the intercooler 31 is disposed above the supercharger 20 and can be cooled by the vehicle head-on airflow.

As shown in fig. 4, the intercooler 31 is connected with an intercooler outlet duct 32, the intake port 11 is connected with an intake manifold 33, the intercooler outlet duct 32 is connected with the intake manifold 33, the intercooler outlet duct 32 extends above the cylinder, the intake manifold 33 is located below the air filter 34, and the intake manifold 33 is connected with the intake port 11. That is, the air entering from the intercooler 31 is cooled and then enters the intake manifold 33 through the intercooler air outlet pipe 32, wherein the supercharger 20 is disposed at the connection between the intercooler air outlet pipe 32 and the intake manifold 33, and the air enters the intake manifold 33 under the supercharging of the supercharger 20 and then enters the engine 10. Specifically, there are two air inlets 11, and the air intake manifold 33 is disposed corresponding to the two air inlets 11, so that the supercharged air can be conveniently sent to the engine 10, and the supercharged air is prevented from accumulating in the air intake manifold 33. The engine 10 may be a two-cylinder inline engine.

Wherein, be provided with first lubricated oil duct in the engine 10, be provided with the second lubricated oil duct in the booster 20, first lubricated oil duct and second lubricated oil duct parallel connection. Because the critical parts of the supercharger 20 require bearing support, the bearings are driven by exhaust gas to operate at very high rotational speeds, the operating environment is harsh, and if the oil pressure is low, which results in slow oil supply, the bearings can be damaged, resulting in turbocharger failure. Therefore, the pressurized oil pumped by the oil pump of the engine 10 is supplied to the first lubricating oil passage and the second lubricating oil passage through the oil inlet pipe 64, so that the supercharger 20 can be lubricated, and the oil lubricated by the supercharger 20 enters the lubricating oil cavity of the engine 10 through the oil outlet pipe 65. That is, the connection between the lubrication system of the supercharger 20 and the lubrication system of the engine 10 facilitates the lubrication of the supercharger 20 without requiring an additional lubrication system, which reduces the cost and saves the space occupied by the engine 10.

Further, a first cooling flow passage is provided in the engine 10, a second cooling flow passage is provided in the supercharger 20, and the first cooling flow passage and the second cooling flow passage are connected in parallel. That is, the coolant flows out of the water outlet of the cooler 61, enters the engine 10 and the supercharger 20 through the water outlet pipe 63, is conveyed to different places of the engine 10 through the first cooling flow channel to be cooled and dissipated, is cooled and dissipated to the supercharger 20 through the second cooling flow channel, and finally returns to the cooler 61 through the water inlet pipe 62. That is, the connection of the cooling system of the supercharger 20 to the cooling system of the engine 10 facilitates cooling of the supercharger 20 without providing an additional cooling system.

As shown in fig. 1-5, atv 100 further includes: continuously variable transmission 41 and derailleur 42, continuously variable transmission 41 and engine 10 drive fit, continuously variable transmission 41 and derailleur 42 drive fit, and derailleur 42 and engine 10 set up the same side at continuously variable transmission 41. The continuously variable transmission 41 uses a transmission belt to transmit power in cooperation with a driving wheel 47 and a driven wheel 47 having variable working diameters, so that continuous change of transmission ratio can be realized, and optimal matching of a transmission system and the working condition of the engine 10 can be obtained. And, continuously variable transmission 41 and engine 10 are in driving cooperation, so that the distribution of the power transmitted to engine 10 can be further improved.

As shown in fig. 5, a mounting chamber 43 is formed in the continuously variable transmission 41, and an air inlet pipe 44 and an air outlet pipe 45 are correspondingly connected to the mounting chamber 43. With the arrangement, when the driving wheel 46 of the continuously variable transmission 41 and the driven wheel 47 of the continuously variable transmission 41 rotate, air flows, air enters from the air inlet pipe 44 in the air inlet box of the continuously variable transmission 41, and the two air inlet pipes of the continuously variable transmission 41 are respectively aligned with the driving wheel 46 and the driven wheel 47, so that the temperature of the continuously variable transmission 41 can be reduced, and the phenomenon that the temperature of the continuously variable transmission 41 is too high to influence normal use can be avoided. In addition, set up the air outlet towards booster 20 on the tuber pipe 45, make things convenient for the air that the tuber pipe 45 blew out to enter into booster 20 in to can make things convenient for booster 20's air inlet, further promote booster 20's pressure boost effect, and then can further promote engine 10's availability factor. The air outlet can also face the exhaust pipe 35 to cool the exhaust pipe 35.

And, an intake filter is connected to the intake duct 44. With this arrangement, it is possible to prevent impurities in the air from entering the mounting chamber 43 to affect the normal use of the continuously variable transmission 41.
