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： PROBLEM TO BE SOLVED: To provide an exhaust gas cooling adapter for an internal combustion engine, the adapter preventing air bubbles from remaining or a cooling water from dwelling in a cooling water flow channel.SOLUTION: In a closing processing part 24, a dent 24c is formed in a water jacket 18. The dent 24c does not present on the upper end extension of a cooling water flow channel 18f, but is arranged above a partial connecting part 19b. Accordingly, the cooling water flowing in the cooling water flow channel 18f does not collide with the dent 24c but only the cooling water flowing in a cooling water flow channel 18d flows lateral to the dent. Hence even when air enters the dent 24c, the air in the dent 24c is discharged instead of remaining as bubbles, by the flow of the cooling water flowing away laterally. Even when only the cooling water enters the dent 24e, the water is also discharged without dwelling. Thus, even when the cooling water in the exhaust gas cooling adapter 2 is heated through the transmission of heat from exhaust gas flowing through an exhaust gas flow channel 16 and from an exhaust manifold 6, a degradation in cooling efficiency or boiling can be prevented from being caused.
摘要翻译：要解决的问题：为了提供一种用于内燃机的排气冷却适配器，适配器防止气泡残留或冷却水在冷却水流动通道中停留。解决方案：在封闭处理部分24中，凹槽24c形成在水套18中。凹部24c不存在于冷却水流动通道18f的上端延伸部上，而是布置在部分连接部分 19B。因此，在冷却水流路18f中流动的冷却水不与凹部24c碰撞，只有在冷却水流路18d中流动的冷却水向凹部侧流动。因此，即使当空气进入凹部24c时，通过横向流动的冷却水的流动，排出凹部24c中的空气而不是作为气泡留下。即使只有冷却水进入凹坑24e，水也排出而不住。因此，即使当排气冷却适配器2中的冷却水通过来自排气流路16的排气和排气歧管6的热量传递而被加热时，也可以防止冷却效率或沸腾的降低被造成版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an exhaust cooling adapter and an internal combustion engine exhaust system which can enhance cooling performance with respect to the whole of exhaust in an exhaust path in which deviation of a heating value to be absorbed from exhaust exists.SOLUTION: Exhaust cooling adapters 28, 36 for respective banks 8, 10 of an internal combustion engine 2 have a constitution in which passage capacities of cooling water passages 44a, 64a in water jackets 44, 64 corresponding to inner peripheral surfaces 50a, 70a on the upper part in a vertical direction against which exhaust through exhaust ports 26, 34 blows strong is expanded by increasing height and width. The presence of an abundance of cooling water can keep the temperature difference with exhaust gas large on the cooling water passage 44a, 64a sides. An abundance of a heating value can be promptly absorbed on the cooling water side. Heat is efficiently absorbed in cooling water through the positive utilization of deviation of a heat transfer quantity from exhaust. Other than the passage capacity, the heat transfer quantity may be increased with a cooling water flow rate, cooling water velocity, unevenness or the like.
摘要翻译：要解决的问题：提供一种排气冷却适配器和内燃机排气系统，其能够提高相对于排气路径中的整体排气的冷却性能，在排气路径中，将要吸收的热值的偏差存在。解决方案：内燃机2的各排8,10的排气冷却适配器28,36具有这样一种构造，其中水套44,44中的冷却水通道44a，64a对应于上部的内周面50a，70a 在垂直方向上，排气口26,34的排气通过增加高度和宽度而膨胀。大量冷却水的存在可以使冷却水通道44a，64a侧的废气温度差大。可以在冷却水侧快速吸收大量的发热量。通过积极利用传热量与排气的偏差，热量可以有效地吸收在冷却水中。除了通过能力之外，传热量可以随着冷却水流量，冷却水速度，不均匀性等而增加。

摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine with a turbocharger that sufficiently prevents heat damage to an actuator to control the turbocharger with a simple configuration.SOLUTION: Cooling-water passages 8b, 12c are formed in a wall 14a over an area from an exhaust manifold 8 to a turbine housing 12. An actuator 20 based on an electric motor is mounted to the outer-surface side of the wall 14a, formed with the cooling-water passage 8b, on the exhaust manifold 8 side. Accordingly, it prevents the actuator 20 from being heated by heat transfer from an exhaust flow inside an exhaust passage 8a. Consequently, it eliminates the need for supplying cooling water to the actuator 20 by piping. Moreover, the actuator may only be mounted to the outer-surface side of the wall 14a. Therefore, it also simplifies the mounting configuration. In such a manner, it is possible to sufficiently prevent heat damage to the actuator 20 to drive a wastegate valve 22 with a simple configuration.

摘要： PROBLEM TO BE SOLVED: To provide an adapter for cooling exhaust of an internal combustion engine, inhibiting concentration of a heat receiving amount on an exhaust manifold side.SOLUTION: The inner surface 40 of an exhaust flow passage 32 has an annular swell part 40c swelling inward in the radial direction and is formed with two tapered parts 40a, 40b on both sides. A large amount of heat is received from the exhaust at the tapered part 40a on an exhaust port 18 side, and a heat receiving amount from the exhaust is small at the tapered part 40b on an exhaust manifold 22 side. Further, the opening diameter of an exhaust discharge port 28 is larger than the opening diameter of an exhaust manifold 22 so that a connection area of both sides is reduced sufficiently and a heat receiving amount from the exhaust manifold 22 can be suppressed sufficiently. Accordingly, on the exhaust manifold 22 side of the adapter 20 for cooling the exhaust, even when heat is transmitted from the exhaust manifold 22, a total heat receiving amount can be reduced and the concentration of the heat receiving amount can be inhibited.
摘要翻译：要解决的问题：提供一种用于冷却内燃机排气的适配器，从而抑制排气歧管侧的受热量的集中。解决方案：排气流路32的内表面40具有沿径向向内膨胀的环状隆起部40c，并且在两侧形成有两个锥形部40a，40b。在排气口18侧的锥形部40a处的排气中接收到大量的热量，并且在排气歧管22侧的锥形部40b处从排气口的受热量较小。此外，排气排出口28的开口直径大于排气歧管22的开口直径，使得两侧的连接区域被充分地减小，并且能够充分地抑制来自排气歧管22的受热量。因此，在用于冷却排气的适配器20的排气歧管22侧，即使当从排气歧管22传递热量时，也可以减少总的热接收量，并且可以抑制热量的集中。版权所有（C）2012，JPO＆INPIT

Therefore, even if condensed water is generated in an exhaust conduit 16, the backflow thereof is prevented. An exhaust flow immediately after introduced from the exhaust inlet port 8 is collided with an upper inner wall face 16a, a long water jacket is formed thereto, and an axial direction of a communication port for ejecting a core cylinder is at an angle with respect to the perpendicular direction.

摘要： PROBLEM TO BE SOLVED: To provide an internal combustion engine cooling water circulation device capable of keeping combustibility of an internal combustion engine good by keeping the temperature of intake air adequate even during cold time and after warming-up.SOLUTION: In a cold state, thermostat valves 34, 38 are closed and a thermostat valve 62 is opened, and an intercooler water pump 50 is stopped. As a result, cooling water does not flow in a radiator 36 but circulates in an exhaust cooling adaptor 20 and an intercooler 18, and so intake air is heated by the intercooler 18. This keeps combustibility good during cold while preventing an intake air system from being frozen. After warming-up, the thermostat valves 34, 38 are opened and the thermostat valve 62 is closed, and the heated cooling water does not flow in the intercooler 18. Cooling water cooled by the intercooler water pump 50 and an intercooler radiator 52 flows in the intercooler 18, instead, to cool the intake air. This keeps combustibility good after warming-up.
