| description | To shorten a warmup operation time by early raising a temperature of oil while making an engine compact in a size by integrating a cooling water return passage to a cylinder block.SOLUTION: A cooling water return passage 22 is integrally formed at a side of an exhaust side face 29 out of longitudinal both side faces of a cylinder block 1. Block-side oil fall passages 31, 32 are formed between a block jacket 6 and the cooling water return passage 22. An expansion part 33 expanded in a longitudinal direction of the cooling water return passage 22 is formed above the block-side oil fall passages 31, 32. Since the cooling water return passage 22 is arranged at the exhaust side face 29 side, the number of members can be reduced and a catalyst case can be shifted to the cylinder block 1, and an engine can be made compact in a size. Since oil is raised in a temperature by cooling water passing a cylinder head 2, a warmup operation time can be shortened.SELECTED DRAWING: Figure 1
【課題】冷却水戻り通路をシリンダブロックに一体してエンジンのコンパクト化を図りつつ、オイルを早期昇温させて暖機運転時間を短縮化する。【解決手段】シリンダブロック１の長手両側面のうち排気側面２９の側に、冷却水戻り通路２２が一体に形成されている。ブロックジャケット６と冷却水戻り通路２２との間に、ブロック側オイル落とし通路３１，３２が形成されている。ブロック側オイル落とし通路３１，３２の上部には、冷却水戻り通路２２の長手方向に広がった拡張部３３が形成されている。冷却水戻り通路２２を排気側面２９の側に配置しているため、部材点数を低減できると共に、触媒ケースをシリンダブロック１に寄せることができてエンジンをコンパクト化できる。シリンダヘッド２を経由した冷却水によってオイルが加温されるため、暖機運転時間を短縮できる。【選択図】図１ |
