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. 1-4.

As shown in fig. 1-4, atv 100 includes: an air filter 34, an engine 10, and a supercharger 20, the engine 10 including a first cylinder 17 and a second cylinder 18, the first cylinder 17 having a first intake port 11 and a first exhaust port 13, the second cylinder 18 having a second intake port 12 and a second exhaust port 14. That is, the first cylinder 17 takes in air and fuel, both of which are mixed and ignited in the first cylinder 17, generates power at the first cylinder 17, and the burned exhaust gas is discharged through the first exhaust port 13. The second cylinder 18 draws in air and fuel, which are mixed in the second cylinder 18 and ignited, generating power at the second cylinder 18, and the combusted exhaust gases are expelled through the second exhaust port 14. An air filter 34 is coupled to the supercharger 20, and the air filter 34 may 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, a supercharger 20 is connected to at least one of the first and second intake ports 11 and 12 to feed pressurized air into the first and second cylinders 17 and 18, although it may be fed into the first or second cylinders 17 and 18 separately. That is, supercharger 20 increases the intake air amount of engine 10 by compressing air. The supercharger 20 may pressurize air entering the supercharger 20, causing the air to be pressurized and then enter the cylinders via the intake ports. 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.

Therefore, by arranging the supercharger 20 between the air filter 34 and the engine 10, the air inflow of the first cylinder 17 and the air inflow of the second cylinder 18 can be increased, so that the first cylinder 17 and the second cylinder 18 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 fuel combustion efficiency is increased, and energy conservation and emission reduction are facilitated.

Specifically, as shown in fig. 2, the supercharger 20 is a turbocharger, and includes: the turbine 21 and the compressor 22 are in driving connection, at least one of the first exhaust port 13 and the second exhaust port 14 is connected to the turbine 21, an air inlet of the compressor 22 is connected to the air filter 34, and the other end is connected to at least one of the first air inlet 11 and the second air inlet 12. With this arrangement, the exhaust gas from at least one of the first cylinder 17 and the second cylinder 18 pushes the turbine in the turbine 21, the turbine 21 drives the compressor 22 which rotates coaxially, and the impeller in the compressor 22 pumps the air delivered from the air filter 34, so that the air is pressurized into the first cylinder 17 and the second cylinder 18, 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 increased synchronously, the compressor 22 compresses more air into the first cylinder 17 and the second cylinder 18, the pressure and the 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.

As shown in fig. 1-4, atv 100 further includes: an exhaust pipe 35 and a muffler 36, the turbine 21 having an exhaust outlet, the exhaust pipe 35 being connected to the exhaust outlet and extending toward the rear, the muffler 36 being provided at the exhaust pipe 35 adjacent to the rear of the exhaust pipe 35, the muffler 36 being located behind the supercharger 20. 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 from the exhaust gas outlet, is finally silenced by the silencer 36 and is then discharged, so that the noise generated by the engine 10 can be reduced. And the silencer 36 direction that so sets up is reasonable, and overall reliability is better.

That is, the first exhaust port 13 corresponds to a first exhaust gas inlet with the first exhaust manifold 211 disposed therebetween, the second exhaust port 14 corresponds to a second exhaust gas inlet with the second exhaust manifold 212 disposed therebetween. The arrangement is such that the exhaust gas discharged from the first cylinder 17 can drive the supercharger 20 alone, and the exhaust gas discharged from the second cylinder 18 can drive the supercharger 20 alone, so as to avoid interference between the exhaust gas generated by the first cylinder 17 and the exhaust gas generated by the second cylinder 18, which affects the working efficiency of the supercharger 20.

According to another alternative embodiment of the present invention, the turbine 21 has an exhaust gas inlet, one end of the first exhaust manifold 211 is connected to the first exhaust port 13, and one end of the second exhaust manifold 212 is connected to the second exhaust port 14, the other end of the first exhaust manifold 211 is communicated with the second exhaust manifold 212, and the other end of the second exhaust manifold 212 is connected to the exhaust gas inlet. That is, the first exhaust manifold 211 is not directly communicated with the exhaust gas inlet, but is communicated with the second exhaust manifold 212, and then the second exhaust manifold 212 is communicated with the exhaust gas inlet, so that the exhaust gas generated by the first cylinder 17 and the exhaust gas generated by the second cylinder 18 can be converged, the first exhaust manifold 211 and the second exhaust manifold 212 can be arranged, two exhaust gas inlets do not need to be arranged on the supercharger 20, and the design difficulty of the supercharger 20 can be reduced. Alternatively, the other end of the second exhaust manifold 212 is connected to the first exhaust manifold 211, and the other end of the first exhaust manifold 211 is connected to an exhaust gas inlet. That is, the second exhaust manifold 212 does not directly correspond to the exhaust gas inlet. Alternatively, the first exhaust manifold 211 and the second exhaust manifold 212 may be connected to each other to form an exhaust manifold, and the exhaust manifold may be connected to the exhaust inlet.

According to yet another alternative embodiment of the present invention, atv 100 further comprises: first exhaust manifold 211, second exhaust manifold 212 and adapter tube, the one end of first exhaust manifold 211 is connected with first exhaust port 13 to the one end of second exhaust manifold 212 is connected with second exhaust port 14, and the other end of first exhaust manifold 211 and the other end of second exhaust manifold 212 all connect in the adapter tube, and the adapter tube is connected with the waste gas import. That is, the adapter tube connects one ends of the first exhaust manifold 211 and the second exhaust manifold 212.

According to an alternative embodiment of the present invention, atv 100 further comprises: a first intake manifold 15 and a second intake manifold 16, the compressor 22 having a first air outlet and a second air outlet, the first intake manifold 15 having one end connected to the first air intake port 11 and the other end connected to the first air outlet, the second intake manifold 16 having one end connected to the second air intake port 12 and the other end connected to the second air outlet. That is, the first intake manifold 15 is disposed between the first air outlet and the first intake port 11, and the second intake manifold 16 is disposed between the second air outlet and the second intake port 12. The arrangement is such that the pressurized gas from the supercharger 20 can enter the first cylinder 17 through the first air outlet and can enter the second cylinder 18 through the second air outlet, thereby avoiding interference between the air in the first manifold and the air in the second manifold, which affects the operating efficiency of the engine 10.

According to another alternative embodiment of the present invention, the compressor 22 has an air outlet, one end of the first intake manifold 15 is connected with the first air inlet 11, and one end of the second intake manifold 16 is connected with the second air inlet 12, the other end of the first intake manifold 15 is connected with the second intake manifold 16, and the other end of the second intake manifold 16 is connected with the air outlet. That is to say, the first intake manifold 15 does not directly correspond to the air outlet, and thus the arrangement can converge the air pressurized by the compressor 22, deliver the air through the second intake manifold 16, and then shunt the air to the joint of the first intake manifold 15 and the second intake manifold 16, so that the arrangement of the first intake manifold 15 and the second intake manifold 16 can be realized, two air outlets do not need to be formed on the compressor 22, and the design difficulty of the compressor 22 can be reduced. Alternatively, the other end of the second intake manifold 16 is connected to the first intake manifold 15, and the other end of the first intake manifold 15 is connected to an air outlet, that is, the second intake manifold 16 does not directly correspond to an air outlet. Or, the first intake manifold 15 and the second intake manifold 16 are connected to an intake manifold, the intake manifold is connected to an intercooler 31, and the intercooler 31 is connected to a compressor air outlet.

According to yet another alternative embodiment of the present invention, atv 100 further comprises: the air compressor 22 is provided with an air outlet, one end of the first air inlet manifold 15 is connected with the first air inlet 11, one end of the second air inlet manifold 16 is connected with the second air inlet 12, the other end of the first air inlet manifold 15 and the other end of the second air inlet manifold 16 are connected to the adapter pipe, and the adapter pipe is connected with the waste gas inlet. That is, the adapter tube connects one ends of the first intake manifold 15 and the second intake manifold 16.

Referring to fig. 1-4, second cylinder 18 is located between first cylinder 17 and booster 20 in the longitudinal direction of atv 100. So configured, it is possible to facilitate piping connections between the first cylinder 17, the second cylinder 18, and the supercharger 20, to facilitate connection of the first exhaust manifold 211 and the second exhaust manifold 212 to the supercharger 20, and to facilitate connection of the first intake manifold 15 and the second intake manifold 16 to the supercharger 20.

As shown in fig. 3 and 4, a plane perpendicular to the lateral direction of the all-terrain vehicle 100 is set as a first reference plane, and a projection of the first cylinder 17 on the first reference plane and a projection of the second cylinder 18 on the first reference plane form an included angle. Among them, the ATV 100 emphasizes aerodynamics, and requires that the smaller the windward side of the ATV 100, the better, the lower the engine 10 cover. In addition, if the length of the engine 10 is shortened, a larger space can be left for the cab. This facilitates increasing the displacement and power by enlarging the cylinder diameter and is suitable for higher cylinder numbers, since the cylinders are already arranged offset from each other. The first cylinder 17 and the second cylinder 18 are V-shaped.

Further, as shown in fig. 3 and 4 in conjunction, in the longitudinal direction of the all-terrain vehicle 100, the first intake opening 11 and the second intake opening 12 are disposed adjacent to each other, and the first exhaust opening 13 and the second exhaust opening 14 are disposed away from each other. So configured, the connection of the first intake manifold 15 with the second intake manifold 16, i.e., the intake of the first cylinder 17 and the second cylinder 18, can be facilitated. Further, the first exhaust port 13 and the second exhaust port 14 are located away from each other, and the arrangement of the first exhaust manifold 211 and the second exhaust manifold 212 can be facilitated, avoiding interference between the first exhaust manifold 211, the second exhaust manifold 212, and the first intake manifold 15 and the second intake manifold 16.

As shown in fig. 1-4, atv 100 further includes: the intercooler 31, the intercooler 31 are connected with an intercooler inlet pipe 33 and an intercooler outlet pipe 32, the intercooler inlet pipe 33 is connected with the compressor 22, and the intercooler outlet pipe 32 is respectively connected with the first air inlet 11 and the second air inlet 12 through a throttle body. Since the air in the air filter 34 is boosted by the supercharger 20 and the temperature thereof is increased, the air taken into the cylinder is cooled by providing the intercooler 31 and being installed between the supercharger 20 and the intake pipe. 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.

As shown in fig. 1, intercooler 31 is located between first cylinder 17 and supercharger 20 in the longitudinal direction of atv 100. That is, the intercooler 31 is disposed adjacent to the second cylinder 18, the piping between the intercooler 31 and the first and second cylinders 17 and 18 may be shortened, or the piping between the two may be directly omitted, so that the all-terrain vehicle 100 may be made more compact.

Wherein, a plane perpendicular to the vertical direction of the all-terrain vehicle 100 is set as a second reference plane, and a projection of the intercooler 31 on the second reference plane is at least partially overlapped with a projection of the second cylinder 18 on the second reference plane, that is, the intercooler 31 can be arranged above the second cylinder 18, so that the intercooler 31 can be conveniently connected with the first cylinder 17 and the second cylinder 18, and the all-terrain vehicle 100 is more compact in structure.

Alternatively, the projection of the intercooler 31 on the second reference surface is located between the projection of the second cylinder 18 on the second reference surface and the projection of the supercharger 20 on the second reference surface, that is, the projection of the intercooler 31 on the second reference surface is not coincident with the projection of the second cylinder 18 on the second reference surface, so that the intercooler 31 and the supercharger 20 can be conveniently connected, and the all-terrain vehicle 100 can also be made to be more compact.

Further, air filter 34 and booster 20 are spaced apart in the lateral direction of ATV 100. So set up, air cleaner 34 and booster 20 interval set up for air after air cleaner 34 filters conveniently gets into in booster 20, conveniently arranges and distributes the space of ATV 100 rationally.

As shown in fig. 2, the intercooler 31 is connected to an intercooler outlet duct 32, the intercooler outlet duct 32 is connected to a throttle valve body, which is then connected to the first intake manifold 15 and the second intake manifold 16, and the intercooler outlet duct 32 extends above the first cylinder 17 and the second cylinder 18. That is, the air entering from the intercooler 31 is cooled and then enters the first intake manifold 15 and the second intake manifold 16 through the intercooler air outlet pipe 32, wherein an air throttle device is disposed at the connection between the intercooler air outlet pipe 32 and the intake manifold, and the air enters the engine 10 through the air throttle device.

In some embodiments of the present invention, 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. By connecting the first cooling flow channel and the second cooling flow channel in parallel, the cooling system of the supercharger 20 is connected to the cooling system of the engine 10, so that the supercharger 20 is conveniently cooled, and an additional cooling system is not required.

Wherein, engine 10 further includes: the crankcase 66, the first cylinder 17 and the second cylinder 18 are disposed on the crankcase 66, and the first cooling flow passage is distributed among the first cylinder 17, the second cylinder 18 and the crankcase 66, that is, the first cooling flow passage can cool and dissipate heat of the first cylinder 17 and the second cylinder 18.

Further, as shown in fig. 1-4, atv 100 further comprises: a radiator outlet pipe 63 is connected between the radiator 61 and the engine 10, water in the outlet pipe 63 flows into the engine to cool parts in the engine, including cylinders, a radiator inlet pipe 62 is connected between the radiator 61 and the engine 10, and water flowing into the engine cools the engine and then flows into the radiator through the radiator inlet pipe 62 to cool. That is, the coolant flows out from the water outlet of the radiator 61, enters the water inlet of the water pump through the water outlet pipe 63 of the radiator, enters the first cooling flow channel from the water outlet of the water pump, and is conveyed to different places of the engine 10 through the first cooling flow channel for heat dissipation and cooling. And the coolant may also enter the second cooling flow passage from the first cooling flow passage and cool the supercharger 20 through the second cooling flow passage. Finally, the coolant in the supercharger 20 and the engine 10 is returned to the radiator 61 through the radiator inlet pipe 62. Accordingly, the supercharger 20 can complete cooling itself by using the liquid cooling cycle of the engine 10, and thus the operation stability of the supercharger 20 can be ensured.

A first lubrication flow passage is provided in the engine 10, a second lubrication flow passage is provided in the supercharger 20, and the first lubrication flow passage and the second lubrication flow passage are connected. As shown in fig. 2, the first lubrication flow path is distributed among the first cylinder 17, the second cylinder 18, and the crankcase 66, and a first oil pipe 64 is connected between the engine 10 and the supercharger 20, and a second oil pipe 65 is connected between the supercharger 20 and the engine 10. Because the critical parts of the turbocharger 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 failure of the turbocharger 20. Thereby, the pressurized oil in the first lubrication flow passage can lubricate the first cylinder 17, the second cylinder 18, and the crankcase 66, and specifically, can lubricate a crankshaft bush, a connecting rod bush, camshafts on both cylinder heads, and the like. And, the pressure engine oil enters the second lubrication flow passage through the first oil pipe 64, so that the supercharger 20 can be lubricated, and the engine oil lubricated by the supercharger 20 flows out through the second oil pipe 65 and returns to the engine 10. 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.

Furthermore, atv 100 further comprises: a continuously variable transmission 67 and a variator, the continuously variable transmission 67 being in driving engagement with the engine 10 and the continuously variable transmission 67 being in driving engagement with the variator. That is, continuously variable transmission 67 is drivingly engaged with engine 10, continuously variable transmission 67 is drivingly engaged with the transmission, and the transmission and engine 10 are disposed on the same side of continuously variable transmission 67. The continuously variable transmission 67 uses a transmission belt and a driving wheel and a driven wheel with variable working diameters to transmit power, so that the transmission ratio can be continuously changed, and the optimal matching of a transmission system and the working condition of the engine 10 is obtained. And, continuously variable transmission 67 is in driving engagement with engine 10, thus further improving the distribution of power transmitted to engine 10.

Further, the transmission has a first output and a second output, which output power in the longitudinal direction of the atv 100 in opposite directions. That is, when the engine 10 is operated, the reciprocating motion of the piston is converted into the rotational motion of the crankshaft by the crank mechanism. The first output of the transmission may transmit power to the rear axle and the second output may transmit power to the front axle.
