Problems solved by technology

However, the existing common method for reducing the amount of inhaled air is to manually close the choke valve by the operator according to the temperature of the use environment, so as to reduce the amount of inhaled air. At the same time, the choke valve must be opened again when the gasoline engine is working normally. The manual operation of the whole process is quite cumbersome, and requires certain skills for the operator, which is not conducive to the popularization and promotion of the product.

Abstract

The invention discloses a portable gasoline engine and an automatic air door control system thereof. The gasoline engine comprises a carburetor. The carburetor is provided with a gas inlet channel with a gas inlet. The automatic air door control system comprises a choke valve and a power unit for driving the choke valve. The gas inlet is opened or closed by the choke valve. The automatic air door control system further comprises a transmission unit and a controller. The transmission unit and a rotary shaft are matched and connected. The controller is provided with a circuit drive module for driving the transmission unit to move so that the choke valve can be controlled to be closed and opened. Automatic closing or opening of the choke valve can be achieved, operation is easy and convenient, no requirement for the skill or experience of an operator exists, and product popularization is facilitated.

Description

technical field [0001] The invention relates to a portable gasoline engine and its automatic damper control system. Background technique [0002] At present, the portable gasoline engine used for garden tools, its air intake system includes air filter, choke valve, carburetor, intake pipe, valve and other components, the main function is to vaporize and mix air and fuel through the carburetor in a certain proportion Combustible gas enters the combustion chamber through the intake passage. In the air intake system of the prior art, air enters the throat of the carburetor through the air filter and the choke valve. The carburetor has a device at the throat of the carburetor to adjust the fuel flow into the throat. Air and fuel are mixed at the throat. Due to the Venturi tube effect, the fuel is vaporized and mixed with air to form a combustible mixture. The combustible mixture is then Through the carburetor and intake duct and intake valve, it finally enters the combustion c...
