Summary:PROBLEM TO BE SOLVED: To provide an engine device with high reliability and high safety which can avoid closure of a pipe line in a confluent portion of blow-by gas leaked from a combustion chamber and intake air (outside air) due to icing even in use at a cold district, especially at a very cold district of -20°C or lower.SOLUTION: An engine device includes heating means (21, 22, 23, 24, 25, and 26) for raising a temperature in a mixing area of intake air flowing in blow-by gas mixing joints (20, 20A, 20B, and 20C) and blow-by gas introduced from a reducing hose (12), and cooling water is used as a heat source in the heating means.SELECTED DRAWING: Figure 3 【課題】寒冷地、特に−２０℃以下の極寒地の使用においても、燃焼室から漏れ出たブローバイガスと吸気（外部空気）との合流部分の管路が着氷で塞がれることのない、信頼性および安全性の高いエンジン装置を提供することを目的とする。【解決手段】エンジン装置は、ブローバイガス混合継手（２０，２０Ａ，２０Ｂ，２０Ｃ）に流れる吸気と還元ホース（１２）から導入されるブローバイガスとの混合領域における温度を上昇させるために加温手段（２１，２２，２３，２４，２５，２６）を備え、当該加温手段における加熱源として冷却水が用いられる。【選択図】図３
