Description
Technical Field
[0001] The utility model relates to the technical field of carburetors, and particularly relates to a dynamometer for a special carburetor of a lawn mower. Background Art
[0002] A dynamometer, usually simply referred to as a "dynamometer", is a device for measuring the performance of a machine.
[0003] A lawn mower, also known as a lawn machine, is a mechanical tool for trimming lawns, vegetation, etc. It is composed of a cutter head, an engine, walking wheels, a walking mechanism, blades, a carburetor, and a control part.
[0004] Currently, a carburetor is a mechanical device that mixes a certain proportion of gasoline and air under the vacuum generated by the operation of the engine. The important role of the carburetor for the engine can be called the "heart" of the engine. Due to the different working conditions of the lawn mower from other equipment, a special carburetor will also be installed on the existing lawn mower. Therefore, it is also necessary to test the engine of the lawn mower to determine whether the adjustment, design, and performance of the special carburetor of the lawn mower meet the actual control requirements, and improve the quality control and design of the special carburetor of the lawn mower; however, there are few dynamometers for lawn mowers in the prior art. For example, a test device that can simulate mowing disclosed in CN202110475771.6, but the structure of the test device is complex and the cost is high; therefore, a dynamometer for a special carburetor of a lawn mower that specifically meets the test of the lawn mower to verify the performance of the carburetor and has a lower cost is needed.
