Embodiment Construction
[0022] Attached below Figure 1-3 The control method for automatically adjusting the air intake of the engine of the present invention is described further:
[0023] like figure 1 As shown: the air intake assembly in the figure is composed of an air intake channel opening 1, an air filter 2, a controller 3, an air flow chamber 4, a fan 5, an air flow channel opening 9 and a housing 10; among them, the fan 5 is composed of a fan bracket 6. The speed regulating motor 7 and the fan blade 8 are composed; the external air enters the air filter 2 through the air inlet channel port 1, the air filter 2 purifies and filters the incoming gas, passes through the air flow chamber 4, and passes through the air flow channel port 9 into the engine; the controller 3 is connected with the speed regulating motor 7 of the fan 4.
[0024] like image 3 As shown: the controller is composed of microprocessor U1 and its peripheral circuits. The microprocessor is a single-chip microcomputer with b...
