PROBLEM TO BE SOLVED: To enable a partial cooling of an engine 1 to be carried out while a heat insulation of the entire engine 1 is being assured.SOLUTION: There are provided: a cylinder head heat insulation cover 30 having a first side wall part 32 oppositely faced against to cover each of both side surfaces in a vehicle width direction at a cylinder head 2 and a cylinder block 3 while being spaced apart against them; and a cylinder block heat insulation cover 40 having a second side wall part 43 for covering each of both side surfaces in a vehicle width direction at the cylinder block 3. The second side wall part 43 is positioned more inside in a vehicle width direction than the first side wall part 32 and the lower part of the first side wall part 32 and the upper part of the second side wall part 43 are overlapped to each other in a vertical direction as seen from the side of the vehicle.SELECTED DRAWING: Figure 1
【課題】エンジン1全体の保温を図りつつ、エンジン1の一部の冷却を可能にする。【解決手段】シリンダヘッド2及びシリンダブロック3における車幅方向の両側側面と間隔を空けて対向し、それぞれの両側側面をそれぞれ覆う第1の側壁部32を有するシリンダヘッド側保温カバー30と、シリンダブロック3における車幅方向の両側側面をそれぞれ覆う第2の側壁部43を有するシリンダブロック側保温カバー40とを備え、第2の側壁部43は、第1の側壁部32よりも車幅方向内側に位置しており、第1の側壁部32の下部と第2の側壁部43の上部とは、車両側方から見たときに、上下方向に重複している。【選択図】図1
