[Detailed description of the invention] The present invention provides a filter approximately coaxially with a communication hole that communicates with the intake port of the carburetor, communicates with the outer surface of the filter, and places the filter at an eccentric position with respect to the communication hole. This relates to an air cleaner equipped with an inlet.

Conventionally, in this type of air cleaner, the suction port is provided eccentrically downward with respect to the communication hole, and the air that passes through the filter and flows from the communication hole into the carburetor is directed downward to the side near the suction port. The flow rate is higher on the opposite side (that is, the flow rate is faster), and the flow rate of the air flowing into the intake port of the carburetor is slow at the top and fast at the bottom. For this reason, in a normal carburetor, the nozzle opening is located at the bottom of the passage, so fuel is ejected excessively, and if the nozzle opening is located in the vertical center, there is a shortage of fuel, and depending on the rotation speed. The flow velocity distribution fluctuated, causing the engine rotation to become unstable.

The present invention provides communication between the filter and the communication hole by setting the air resistance of the air passage on the suction side between the filter and the communication hole to be appropriately larger than that of the air passage on the opposite side. The purpose is to make the distribution of air flow velocity uniform within the holes and the intake port of the carburetor, thereby eliminating fluctuations in fuel supply and stably rotating the engine.

In the figure, reference numeral 1 denotes an air cleaner connected to a carburetor 3, which is constructed as follows. That is, 5 is a main body case provided with a communication hole 9 communicating with the intake port 7 of the carburetor 3, a filter 11 is provided coaxially with the communication hole 9, and is held between the lid case 13. The lower end of the lid case 13 is the shaft 15
The hook-shaped locking piece 17 at the upper end engages with a locking portion 19 of the main body case 5 by an inclined locking surface 18. Inside the lid case 13, there is an intake chamber 21 facing the outer surface of the filter 11.
is formed, and the lower part of the intake chamber 21 communicates with the atmosphere through an intake port 23 provided at the lower part of the main body case 5. 25 is a cover fixed to the upper part of the lid case 13. The space between the filter 11 and the communication hole 9 consists of a lower air passage 27 on the suction side and an air passage 29 on the opposite side above. It is provided in an area smaller than the communication path 33 provided therein. That is, the air passage 27 on the suction side is set to have an appropriately larger air resistance than the air passage 29 on the opposite side. Therefore, since the air passage 2 on the suction side is close to the suction port 23, the air flow rate increases.
The air resistance 7 increases, and the flow velocity of air in the communication hole 9 and the intake port 7 becomes uniform.

In the above embodiment, the air taken in from the suction port 23 enters the intake chamber 21 and passes through the filter 11.
The air passes through the air passage 27 on the suction side and enters the communication hole 9 after being divided into a lower air passage 27 on the intake side and an air passage 29 on the opposite side above. Air passage 29 on the opposite side of the resistance
Since it is appropriately larger than the communication hole 9,
This makes it possible to make the flow velocity distribution within the intake port 7 uniform.
