Multi -cylinder miller cycle engine is in coordination with admitting air economizer

The utility model discloses a multi -cylinder miller cycle engine is in coordination with admitting air economizer and control method, the device includes: the air receiver, it is through air intake branch intercommunication (air) intake valve for store the high pressure and low temperature combustible gas mixture of combustion chamber, and the control valve, it sets up in the air intake branch for the opening and closing of control channel, the machinery moving valve has unidirectional flux's ability, and gas gets into the combustion chamber in can following main admission line, and the gas of combustion chamber can't return. Wherein, when the control valve was opened, high pressure and low temperature combustible gas mixture got into the combustion chamber, with air inlet pipe's the burning acting together of admitting air. The utility model discloses an engine is air inlet unit in coordination, can temporarily store miller engine compression stroke exhaust high pressure and low temperature combustible gas
