The invention relates to an electric air inlet boosting device which uses a brushless motor as the power of an axial flow fan and uses air pressure generated by the fan for carrying out air inlet boosting on an internal combustion engine. The electric air inlet boosting device is characterized in that an air outlet of an air filter is fixedly connected with an air inlet of the brushless axial flowfan, an air exhaust port of the axial flow fan is fixedly connected with one end of a transition pipe, and the other end of the transition pipe is fixedly connected with an air inlet pipe port of theinternal combustion engine. The axial flow fan uses the brushless motor as the power, the brushless motor is driven by three-phase alternating current generated by a frequency-variable speed regulator, and a frequency conversion signal needed by the frequency-variable speed regulator is provided by a microprocessor according to the working situation of the internal combustion engine. The electricair inlet boosting device not only leads the role of enhancing the power of the internal combustion engine to be more significant, but also has the advantages of simple structure and convenient installation.
Description
Technical field [0001] The invention relates to a device for supercharging the intake air of an internal combustion engine by using the wind pressure generated by a brushless axial flow fan, which provides a new method for supercharging exhaust gas. Not only can the promotion effect of the power of the internal combustion engine be more remarkable, but also the structure is simple and the installation is convenient. Background technique [0002] According to analysis: 25%--40% of the energy is discharged by the internal combustion engine in the form of exhaust gas after the fuel is burned. At present, the exhaust gas energy of the internal combustion engine is only used to pressurize the intake air, the so-called turbocharging, which can increase the output power of the internal combustion engine by about 25%. However, due to the characteristics of its own structure, turbocharging has some insurmountable defects: [0003] 1. The turbocharged driving turbine and the driven ...
