Summary:To improve a mixing property of intake air and recirculated exhaust gas by using an adsorbent for fuel evaporation gas.SOLUTION: An engine system includes: an engine; an intake pipe connected to the engine; an exhaust pipe connected to the engine; a throttle valve provided on the intake pipe; EGR piping for connecting the exhaust pipe to the intake pipe so that a part of exhaust gas re-circulates to the intake pipe, and connected to the intake pipe at an upstream position of the throttle valve in the flow of the intake air; and an adsorbent disposed inside of the intake pipe at a position between the throttle valve and the EGR piping to adsorb fuel evaporation gas from the engine.SELECTED DRAWING: Figure 1 【課題】燃料蒸発ガスの吸着材を用いて、吸気と再循環された排気ガスとの混合性を向上すること。【解決手段】エンジンシステムは、エンジンと、エンジンに接続される吸気管と、エンジンに接続される排気管と、吸気管に設けられるスロットルバルブと、排気管を吸気管に接続し、排気ガスの一部を吸気管に再循環させるＥＧＲ配管であって、吸気の流れにおいて、スロットルバルブの上流の位置で吸気管に接続される、ＥＧＲ配管と、スロットルバルブとＥＧＲ配管との間の位置において、吸気管の内部に配置され、エンジンからの燃料蒸発ガスを吸着する吸着材と、を備える。【選択図】図１
