Definitions

  • the present invention relates to a straddled vehicle including an engine and an air cleaner.
  • an air cleaner In a straddled vehicle, an air cleaner is generally provided at a position relatively close to the head of a rider with the rider riding the straddled vehicle. Therefore, the rider easily hears the intake noise generated from the air cleanerduring traveling of the vehicle. As such, the rider might recognize an operating state of the engine by hearing the intake noise generated from the air cleaner and adjust an operation amount of an accelerator grip during traveling of the vehicle. However, it is difficult to say that the relationship between an intake noise and an operating state of the engine is easy for the rider to recognize. It is difficult for a rider who is not skilled in driving a saddled vehicle to recognize the operating state of an engine even when hearing an intake noise.
  • An object of the present invention is to provide a straddled vehicle that facilitates recognition of an operation state of an engine by a rider when the rider hears an intake noise.
  • An air cleaner includes an air cleaner case, a filter element, an air intake duct and an air supply duct, for example.
  • the air cleaner case has an inner space.
  • the filter element sections the inner space of the air cleaner case into an upstream space and a downstream space.
  • the air intake duct is provided to guide air from the outside of the air cleaner case to the upstream space.
  • the air that is guided to the upstream space is guided to the downstream space while being cleaned through the filter element.
  • the air supply duct is provided so as to further guide the air in the downstream space of the air cleaner case to the engine.
  • the inventors of the present invention conducted an experiment in regard to the relationship between the rotation speed of the engine and the level (volume) of an intake noise heard by the rider by using an air cleaner including only one air intake duct. As a result, it was found that the level of intake noise increases at a substantially constant change rate as the rotation speed of the engine increases in the air cleaner including only one air intake duct.
  • an intake noise change rate the change rate of the level of intake noise obtained when the rotation speed of the engine changes.
  • the inventors of the present invention considered to make the intake noise change rate obtained when the rotation speed of the engine was in a specific rotation speed range be different from the intake noise change rate obtained when the rotation speed of the engine was in another rotation speed range.
  • the level of intake noise increases abruptly, for example.
  • the rider can relatively easily recognize whether the rotation speed of the engine is in the specific rotation speed range or the other rotation speed range.
  • the air intake duct has a natural frequency, and an air column in the air intake duct resonates when an intake noise having a specific wavelength is generated.
  • the inventors of the present invention paid attention to this mechanism, and fabricated a prototype and conducted an experiment in regard to the configuration of the air cleaner in which the intake noise change rate was made to be different depending on the rotation speed of the engine.
  • the inventors of the present invention fabricated an air cleaner including three air intake ducts, and measured the level of an intake noise generated from the air cleaner when the rotation speed of an engine was increased. With this experiment, a measurement result in which the intake noise change rate in the specific rotation speed range was larger than the intake noise change rate in the other rotation speed range was obtained. This is because the resonance sounds generated from the three air intake ducts overlap with one another in the specific rotation speed range of the engine.
  • the lengths of the plurality of tubular portions are set individually, so that a degree of freedom in selecting the frequency of the intake noise generated from the air cleaner is improved.
  • a straddled vehicle according to one embodiment of the present invention will be described below with reference to the drawings.
  • a motorcycle will be described as one example of the straddled vehicle.

  • the direction in which the arrow is directed in the left-and-right direction LR is referred to as leftward, and its opposite direction is referred to as rightward.
  • the motorcycle 100 of Fig. 1 includes a metallic body frame 1.
  • the body frame 1 includes a main frame 1M and a rear frame 1R.
  • the front end of the main frame 1M constitutes a head pipe HP.

  • the intake noise change rate of an air cleaner provided in a straddled vehicle is determined based on the number, shape and size of air intake ducts provided in the air cleaner.
  • the inventors of the present invention have discovered that a rider can identify whether the rotation speed of the engine 5 is in the specific range by hearing an intake noise with an air cleaner including three or more air intake ducts.
  • the three air intake ducts 410 are provided in the air cleaner 10 such that the first intake noise change rate is larger than the second intake noise change rate.
  • the lengths of the three air intake ducts 410 are set to be different from one another. Specifically, as shown in Figs. 2 and 3 , the air intake duct 410A is the longest and the air intake duct 410B is the shortest among the three air intake ducts 410.
  • the length of an air intake duct having an upstream opening and a downstream opening is the length of a central axis of an air intake passage of the air intake duct extending from the upstream opening to the downstream opening.
  • Each of the three air intake ducts 410 has a natural frequency corresponding to the length of the air intake duct. Therefore, the resonance frequency of an intake noise generated by resonance in the air intake duct 410A, the resonance frequency of an intake noise generated by resonance in the air intake duct 410B and the resonance frequency of an intake noise generated by resonance in the air intake duct 410C are different from one another. In this case, the pitches of the intake noises generated in the three air intake ducts 410 are different from one another. Basically, in air intake ducts, the larger the length of an air intake duct is, the lower the pitch of an intake noise generated from the air intake duct is, and the smaller the length of an air intake duct is, the higher the pitch of an intake noise generated from the air intake duct is.

  • the aperture areas of the upstream openings 411, 421, 431 of the three air intake ducts 410 provided in the air cleaner 10 are different from one another.
  • the three upstream openings 411, 421, 431 are formed such that the aperture area of the upstream opening 411 is smaller than that of the upstream opening 421 and the aperture area of the upstream opening 421 is smaller than that of the upstream opening 431.
  • the aperture area of the upstream opening 411 of the air intake duct 410A is the smallest, and the aperture area of the upstream opening 431 of the air intake duct 410C is the largest.
  • the level of the intake noise generated from the air intake duct 410A is lower than the levels of the intake noises generated from the air intake ducts 410B, 410C. Further, the level of the intake noise generated from the air intake duct 410B is lower than the level of the intake noise generated from the air intake duct 410C.
  • the upstream opening 421 of the air intake duct 410B is formed to be directed toward the head of the rider who rides the motorcycle 100. Therefore, an excessive increase in level of the intake noise that is output toward the rider can be suppressed.
  • each of the upstream openings 411, 421, 431 is substantially rectangular and has curved corner portions. With such a shape, a high flow regulating effect can be obtained in the upstream space US as compared to the case where each upstream opening 411, 421, 431 has corner portions that are bent at a right angle. Further, as described above, in a case where each of the upstream openings 411, 421, 431 is substantially rectangular, generation of dead spaces among the air intake passages P1, P2, P3 is reduced as compared to the case where the upstream openings 411, 421, 431 are circular.

  • the direction in which the intake noise generated from the air intake duct 410A is output, the direction in which the intake noise generated from the air intake duct 410B is output and the direction in which the intake noise generated from the air intake duct 410C is output are different from one another.
  • the upstream opening 411 of the air intake duct 410A is directed obliquely, rearwardly and rightwardly.
  • the upstream opening 421 of the air intake duct 410B is directed upwardly.
  • the upstream opening 431 of the air intake duct 410C is directed leftwardly.
  • the downstream openings 412, 422, 432 of the three air intake ducts 410 are all directed downwardly inside of the air cleaner case 200.
  • the air flowing into the upstream space US of the air cleaner case 200 from the three air intake ducts 410 flows in the common direction, and the flow of air generated in the upstream space US is stabilized.
  • an occurrence of turbulence in the upstream space US is suppressed as compared to the case where the downstream openings 412, 422, 432 are directed in different directions. Therefore, a reduction in output of the engine 5 due to an occurrence of turbulence in the air cleaner 10 is suppressed.
  • the second passage forming member 320 is formed such that the downstream portions of the three air intake ducts 410 extend downwardly in the upstream space US.
  • the droplets flow downwardly in the upstream space US. This prevents the droplets from directly adhering to the filter 501, so that a reduction in air intake efficiency due to the filter 501 being wet is suppressed. Further, the droplets that have entered the air cleaner 10 are prevented from being supplied to the engine 5. Further, because the air passing through the three air intake ducts 410 flows downwardly in the upstream space US of the air cleaner 10, a high flow regulating effect can be obtained.
  • the second passage forming member 320 has the configuration in which three tubular portions 321, 322, 323 forming the other parts of the three air intake ducts 410 are integrated.
  • the lengths of the three tubular portions 321, 322, 323 of the second passage forming member 320 may be the same or different from one another.
