摘要： A gas turbine engine includes a compressor section and a combustion section with a scroll, a scroll baffle, a combustor, and a combustor case. The scroll defines an interior scroll flow path. The scroll baffle surrounds the scroll to define a scroll cooling passage. The combustor case surrounds the combustor and the scroll baffle to define a collector space. Moreover, the engine includes a turbine section with a turbine rotor and a turbine rotor blade shroud that includes a shroud cooling passage. The compressor flow path is fluidly connected to the scroll for cooling the scroll. Also, the scroll cooling passage is fluidly connected to the shroud cooling passage for cooling the turbine rotor blade shroud. Furthermore, the shroud cooling passage is fluidly connected to the collector space. Flow from the collector space flows into the combustor, along the interior scroll flow path, toward the turbine rotor.

摘要： A reservoir groove for storing condensate water is formed on a lower part side of a link chamber inside a turbine housing. The reservoir groove is formed such that, assuming that water vapor contained in an exhaust gas retained inside the link chamber is completely condensed and liquefied after an engine stops its operation, a height position of a reference water surface of the condensate water stored in a reservoir area, which includes a space inside the reservoir groove in the link chamber, is lower than a height position of a lowermost part of the link mechanism.

摘要： A turbine housing has a cavity that defines a turbine axis, and has a volute. The volute comprises a volute passage spiralling radially inwards towards the cavity, a substantially annular throat positioned around the cavity between it and the volute passage, and a tongue terminating at a distal tongue tip. In a plane containing the turbine axis and the tongue tip, the throat defines a line of minimum clearance, the volute passage and tongue tip co-operatively define a preliminary inlet area, and the tongue tip defines a tongue tip lateral centerline. The line of minimum clearance and the preliminary inlet area co-operatively define a line of passage offset, which connects the centroid of the preliminary inlet area and a point half way along the line of minimum clearance. The line of passage offset is not perpendicular to the turbine axis, and the tongue tip lateral centerline and the line of passage offset define an angle therebetween of at least 60 degrees.

摘要： An asymmetric twin scroll turbine 10 combined with an integrated exhaust manifold cylinder head 20 may be designed to accommodate mixed, radial or axial flow turbines. The asymmetric twin scroll turbine 10 includes a first scroll 11 and second scroll 12 wherein the first scroll 11 is larger and has greater mass flow capacity than the second scroll 12. The larger volute increases flow capacity and counteracts backpressure creating evenly balanced or equalized peak pressures and pulsations between both volutes and balancing of gas flow between cylinder sets. By equalizing peak pressures, pulsations, and gas flow between cylinder sets, engine self-ignition can be avoided in the cylinder set that would have had the largest peak pressures and pulsations. By in creasing flow capacity of the larger volute and balancing gas flow between cylinder sets, the turbine pressure differential is reduced and the engine can operate more efficiently, improving fuel economy.
摘要翻译：与集成的排气歧管气缸盖20结合的不对称双涡旋涡轮机10可以被设计成适应混合的，径向的或轴向的涡轮机。不对称双涡旋涡轮10包括第一涡旋件11和第二涡旋件12，其中第一涡旋件11较第二涡旋件12更大并且具有比第二涡旋件12更大的质量流量。较大的蜗壳增加流量并抵消背压，从而产生均匀平衡或均衡的峰值压力两个蜗壳之间的脉动和气缸组之间气流的平衡。通过平衡气缸组之间的峰值压力，脉动和气体流量，可以避免在具有最大峰值压力和脉动的气缸组中引擎自点火。通过在气缸组之间增大蜗壳的流量并平衡气体流量，降低涡轮压差，使发动机更有效地运转，提高燃油经济性。
