摘要： PROBLEM TO BE SOLVED: To perform the feed of a high oil pressure to a valve timing varying mechanism as an amount of lubricating oil necessary to a lubrication needing portion, such as a bearing part and a valve system is ensured, in a hydraulic control device for the lubricating oil system of an internal combustion engine. SOLUTION: In a lubricating oil passage 54 to interconnect a lubrication oil pump 50 and the lubrication necessary portion of an internal combustion engine, a control valve 70 is arranged in a spot situated downstream from a portion where a high pressure passage 66 to a valve timing control valve 38 is branched. A control valve 70 responds to a pressure in the lubrication oil passage 54 but at a high oil temperature (100 deg.C) or more, at which a lubrication pressure is reduced, and during low rotation (600rpm), a gap G to ensure a minimum lubricating oil amount to the lubrication necessary portion of an internal combustion engine is ensured between a valve element 70-1 and a valve seat 70-2. Thereby, the feed of oil to a valve timing mechanism is effected in priority during a low oil pressure and valve timing switching responsiveness is ensured.

摘要： PURPOSE:To suppress the sharp reduction of the engine revolution speed and engine stall by ON/OFF-controlling an air conditioner according to the engine revolution speed determined according to the load of the air conditioner. CONSTITUTION:In an air conditioner control circuit 20, the engine revolution speed characteristic (hysteresis) is constituted on the basis of each engine revolution speed r1, r2 selected according to the coolant pressure by a pressure sensor 12 of a compressor 10 for air conditioning, and the engine revolution speed r1, r2 determined by a judging circuit 18 and the signal input from an engine revolution speed sensor 14 are compared. When the engine revolution speed detected by the sensor 14 is larger than a set revolution speed r1, an air conditioner starts operation. When the engine revolution speed becomes less than the set revolution speed r2, the operation of the air conditioner is suspended. In this case, if the pressure of the air compressor 10 is high, and the load of the air conditioner which is applied onto the engine is large, the revolution speed of the engine for controlling the ON/OFF of the air conditioner is set high, and the smooth idling can be secured.

摘要： PROBLEM TO BE SOLVED: To provide a pipe body for cooling exhaust gas which prevents dirt appearance of an internal combustion engine without using a cover, even when cooling water is leaked from a passage connection section.SOLUTION: Steps 26b and 26c are formed on an outer peripheral surface 2b of a cooling adapter 2 oriented upward in the vertical direction, and guide the flow of the cooling water leaked from a cooling water delivery section 24 to the outer peripheral surface 2b into an upper end portion of a vertical groove 30. The cooling water flowed down along the vertical groove 30 is separated at the lower side thereof from the cooling adapter 2, blocking free spread and flow of the leaked cooling water on the cooling adapter 2, to prevent the dirt appearance of the internal combustion engine. Further, the front end of an exhaust manifold 6 is divided into two. This allows the leaked cooling water to leave the cooling adapter 2 without contacting the exhaust manifold 6, causing no durability problem of the exhaust manifold 6.
摘要翻译：要解决的问题：即使当冷却水从通道连接部分泄漏时，也提供一种用于冷却排气的管体，其防止内燃机的污物外露，而不需要使用盖子。解决方案：步骤26b和26c形成在冷却适配器2的外周面2b沿垂直方向向上取向，并且将从冷却水输送部24泄漏的冷却水的流动引导到外周面2b成为垂直槽30的上端部。沿着垂直槽30向下流动的冷却水在其下侧与冷却适配器2分离，阻止泄漏的冷却水在冷却适配器2上的自由扩张和流动，以防止内燃机的污物外观。此外，排气歧管6的前端分为两部分。这允许泄漏的冷却水离开冷却适配器2而不与排气歧管6接触，从而不会导致排气歧管6的耐久性问题。
