The invention relates to an ignition type engine throttle-valve-free air intake system. The system comprises an air intake pipe (2), a pressurizer (4), an intercooler (7), an intercooler air outlet pipe (5) and an engine (1) which communicate in sequence. The pressurizer (4), the intercooler (7) and the engine (1) are connected with an electronic control unit (9), the air intake pipe (2) and the intercooler air outlet pipe (5) communicate through a butterfly valve (6), and the electronic control unit (9) carries out opening degree control over the butterfly valve (6). Compared with the prior art, a throttle valve is not needed, engine pump gas losses are reduced, and the economic property of the engine is improved. 本发明涉及一种点燃式发动机无节气门进气系统，包括依次连通的进气管(2)、增压器(4)、中冷器(7)、中冷器出气管(5)和发动机(1)，所述的增压器(4)、中冷器(7)和发动机(1)均与电子控制单元(9)连接，所述的进气管(2)与中冷器出气管(5)通过蝶阀(6)连通，所述的电子控制单元(9)对蝶阀(6)进行开度控制。与现有技术相比，无需节气门，减少发动机泵气损失，降提高了发动机的经济性能。
