Embodiment 1

[0053] In order to clearly describe the installation angles of the filter element 14 and the separator 13, a three-dimensional coordinate system is introduced in this embodiment for description. Take the motorcycle centerline as the X axis, the Y axis perpendicular to the X axis in the horizontal plane, and the Z axis perpendicular to the horizontal plane.

[0054] The forward direction of the motorcycle is parallel to the X-axis, and in this embodiment, the negative direction of the X-axis is set to be the same as the forward direction of the motorcycle.

[0055] The vertical plane where the centerline of the motorcycle is located is the XZ plane, that is, the base plane that forms an included angle with the filter element 14 and the dividing plate 13;

[0056] The plane perpendicular to the center line of the motorcycle is the YZ plane, that is, the projection plane of the filter element 14;

[0057] The ground is the XY plane.

[0058] Such as figure 1 with figure 2 As...

Embodiment 2

[0071] In order to prevent the dust and silt filtered out by the filter element 14 from clogging the filter holes on the filter element 14 and affecting the air intake efficiency. In this embodiment, on the basis of Embodiment 1, the installation angle of the filter element 14 is optimized and adjusted again.

[0072] Such as Image 6 As shown, the filter element 14 is inclined towards the XY plane and forms an included angle θ with the separator 13 or the XZ plane. The angle between the filter element 14 and the XY plane, that is, the ground, is 90°-θ, and the larger the angle θ is, the larger the projected area of ​​the filter element 14 on the XY plane is. The vibration of the vehicle body produced during the running of the motorcycle and the effect of gravity work together to shake off the dust and silt adhering to the filter element 14 and accumulate them at the bottom of the filter front cavity 15 . When maintaining the air filter 1, the pre-filter cavity 15 is cleaned...

Embodiment 3

[0074] In order to simplify the maintenance steps of the air filter 1 and make the air filter 1 easy to disassemble and clean, this embodiment is based on the embodiment 1 or embodiment 2, and the housing 11, the cover body 12 and the partition 13 are three The connection mode between users has been optimized.

[0075] Such as image 3 with Figure 7 As shown, the installation method of the partition 13 is firstly optimized so that the circumferential edge of the partition 13 is clamped in the fastening gap between the cover 12 and the housing 11, and the partition 13 can also be taken out when the cover 12 is removed. Cleaning, and cleaning and maintenance can also be carried out in the housing 11 at the same time.

[0076] Since the angle α is formed between the partition 13 and the XZ plane, if the plan of interposing the partition 13 in the fastening gap between the cover and the casing 11 is to be realized, the edge shape of the casing 11 and the cover 12 needs to be ad...

Abstract

The invention discloses a motorcycle intake and exhaust control system and a motorcycle. The motorcycle intake and exhaust control system comprises an intake mechanism, an engine and an exhaust mechanism which are sequentially connected. The air intake mechanism comprises an air filter, the exhaust mechanism comprises a first exhaust pipe and a conversion exhaust assembly, the air filter, the engine, the first exhaust pipe and the conversion exhaust assembly are sequentially connected, the length of the first exhaust pipe is 250-480 mm, and the effect of reducing the emission amount of the motorcycle is achieved. In addition, a partition plate in the air filter inclines towards the rear of the motorcycle and forms an included angle alpha with the vertical plane where the center line of the motorcycle is located, a filter element inclines towards the rear of the motorcycle and forms an included angle beta with the partition plate, and the included angle between the filter element and the vertical plane where the center line of the motorcycle is located is the sum of alpha and beta, so that the air intake efficiency of the air filter is sequentially improved, and the performance of the engine is improved to make up for the performance damage influence of an exhaust mechanism on the engine. The air filter can be detached from the side of the motorcycle.

Description

technical field [0001] The invention belongs to the technical field of motorcycle intake and exhaust control systems, and in particular relates to a motorcycle intake and exhaust control system and the motorcycle. Background technique [0002] With the gradual improvement of social economic level and environmental protection requirements, the emission standards for motorcycles are becoming increasingly stringent. The EU regulations clearly stipulate that newly certified motorcycles will be enforced to implement the Euro V emission regulations from 2020. In order for motorcycle products to meet Euro V emission limits, it is necessary to improve and enhance motorcycle emission control strategies. Among them, the more common way to improve the exhaust structure is to adjust the precious metal content of the catalyst in the catalytic converter on the exhaust pipe to improve the effect of the catalyst, but the increase of the precious metal content in the catalyst will increase ...
