Gasoline injection method and device with exhaust gas recirculation

The invention provides a gasoline injection method with exhaust gas recirculation and a device thereof. The gasoline injection method with exhaust gas recirculation mainly includes that automobile exhaust is inducted into a fuel injector and then mixed with gasoline at a fuel injection nozzle to form bubble spray. Following the gasoline, the exhaust gas enters a motor cylinder and then forms internal exhaust gas recirculation. The gasoline injection device with exhaust gas recirculation mainly comprises a fuel injection nozzle, a fuel injector mixing chamber, a fuel injector pin valve, a fuel injector body, a lower electromagnetic valve of the fuel injector, an upper electromagnetic valve of the fuel injector, a gasoline inlet filtering port, an exhaust gas inlet, an exhaust gas one-way valve and a conducting wire sealing port.
