The invention provides a gasoline engine load adjusting method and device. The gasoline engine load adjusting device comprises a gasoline engine, a throttling valve installed on an air intake pipe of the gasoline engine and an EGR circuit communicated with the gasoline engine. The EGR circuit comprises an EGR valve and an EGR cooler which are connected in sequence. The inlet of the EGR valve is communicated with an exhaust pipe of the gasoline engine. The outlet of the EGR cooler is communicated with the air intake pipe of the gasoline engine. A mixed gas temperature sensor for measuring the temperature of mixed gas is installed on an air intake manifold of the gasoline engine. An EGR cooler electronic circulation water pump is connected between the liquid inlet and the liquid outlet of the EGR cooler and used for controlling the flow of cooling water. The front end of a general air intake pipe of the gasoline engine is provided with an air flow meter for measuring the mass flow rate of the air. The throttlin
