Abstract

The invention provides an electric turbocharging device and belongs to the field of automobile manufacturing. A turbocharging fan (3) is installed in front of a throttle of an automobile engine and behind an air filter for air inflow and supercharge of an engine cylinder. A vacuum tube amplifier (VTA) signal of an engine throttle position sensor (1) is sent to a control module (2) to control the rotation speed of the turbocharging fan (3). The rotation speed of a turbocharging fan motor is controlled through the VTA signal, air inflow amount which is large enough is guaranteed, necessary conditions are provided for explosive type quick combustion of fuel in the cylinder, the low-rotation-speed air inflow amount in the natural air suction engine is increased, and torque and output power of a medium-and-low-rotation-speed interval are improved.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing. Background technique [0002] As we all know, engine turbocharging can increase the power and torque of the engine without changing the displacement, so that sufficient oxygen and fuel can be fully burned in the cylinder to achieve higher power output and environmental protection requirements. However, the mechanical supercharger (exhaust gas turbocharger) used in the past has high manufacturing cost and high maintenance cost. And it is difficult and expensive to install the naturally aspirated engine that has been sold, which is the reason for the difficulty in popularization. Electric turbocharger scroll fan supercharging is a method to replace mechanical supercharging (exhaust gas turbocharging) at present. There are many types of electric turbofans. Although many people hold positive views on electric turbochargers, due to lack of Stable and effective control methods have not yet bee...
