Description

technical field

[0001] The invention relates to a detection device for the air intake resistance of an air filter, in particular to a detection device for the air intake resistance of a general-purpose machine with a small flow rate. Background technique

[0002] The air intake resistance of the air filter has a great impact on engine performance and fuel consumption. If the intake resistance is too large, the intake air volume will be reduced, and the engine will not get enough air for complete combustion. The mixture will become richer and the fuel consumption will decrease. As a result, the fuel economy will deteriorate, the exhaust smoke will be too large, and the power will be reduced.

[0003] The intake resistance of an air filter depends on many variables, including the shape of the piping, the smoothness of the conduit, the type of flexible joint, the size of the tube, the construction of the intake cap, the type of elbow, etc. When a product is manufactured, its i...
