Beschreibung
Zusammenfassung:	The invention discloses an engine air inlet device, a throttle valve control method and related equipment, the device comprises a first air inlet manifold, a second air inlet manifold and an engine air inlet pipe, the first air inlet manifold is connected with the engine air inlet pipe, the second air inlet manifold is connected with the engine air inlet pipe, the first air inlet manifold is provided with a first air inlet throttle valve and a heating grid, and the heating grid is provided with a second air inlet throttle valve. The second intake manifold is provided with a second intake throttle valve and an EGR exhaust gas inlet. Fresh inlet air heated by EGR waste gas and fresh inlet air heated by the heating grid are treated separately through the first air inlet manifold and the second air inlet manifold. Due to the fact that the temperature of the heating grid needs time to be increased to the required temperature, the engine device can effectively prevent EGR waste gas which is high in temperature and
