Description
技术领域technical field
本发明属于涡轮增压器技术领域，特别是涉及一种涡轮增压器涡轮进气降温装置。The invention belongs to the technical field of turbochargers, in particular to a turbocharger turbine air intake cooling device.
背景技术Background technique
涡轮增压器是利用发动机燃烧时产生的废气来推动涡轮，进而带动压气机转动，由此达到增大发动机进气量和发动机功率的目的。为了适应越来越严格的排放法规，达到最好的排放效果，对于汽油增压发动机，总希望在满足闭环控制条件时，将发动机空燃比控制在最佳废气转换空燃比上。但随着发动机负荷和转速越来越高，如果一直控制在最佳废气转换空燃比上，排气温度会越来越高，超出或接近涡轮的耐受值。现有的涡轮增压器冷却方法主要对涡壳和涡轮增压器轴承进行冷却，但这样会造成涡轮产生热损伤，从而缩短涡轮的工作寿命。The turbocharger uses the exhaust gas generated during the combustion of the engine to drive the turbine, and then drives the compressor to rotate, thereby achieving the purpose of increasing the intake air volume of the engine and the engine power. In order to meet the increasingly stringent emission regulations and achieve the best emission effect, for gasoline supercharged engines, it is always hoped that the engine air-fuel ratio should be controlled at the optimum exhaust gas conversion air-fuel ratio when the closed-loop control conditions are met. However, as the engine load and speed become higher and higher, if the exhaust gas conversion air-fuel ratio is always controlled at the optimum exhaust gas conversion, the exhaust gas temperature will become higher and higher, exceeding or approaching the tolerance value of the turbine. The existing turbocharger cooling method mainly cools the volute and turbocharger bearings, but this will cause thermal damage to the turbine, thereby shortening the working life of the turbine.

所述的单向阀11为气动或电动单向阀。The one-way valve 11 is a pneumatic or electric one-way valve.
现将本发明提供的涡轮增压器涡轮进气降温装置的工作原理阐述如下：Now the operating principle of the turbocharger turbine intake cooling device provided by the invention is set forth as follows:
在涡轮增压器工作过程中，废气从发动机排气歧管接口1经文丘里管喉管9流入文丘里管8，然后经过涡轮进气口6进入到涡壳13的内部，之后带动涡轮5以及同轴设置的压气机2一起转动，继而通过涡轮出气口7向外流出；与此同时，空气通过压气机进气口3进入到压气机壳12的内部，经压气机2增压后流入压气机出气管4向外排出。当废气流经文丘里管喉管9时，由于流速增大，压强降低至低于压气机出气管4内的压力。当废气温度超过设定值时，打开单向阀11，这时压气机出气管4内的空气流将经过单向阀11流入文丘里管喉管9，继而流入文丘里管8上部，并与来自发动机排气歧管接口1的废气混合后经涡轮进气口6进入到涡壳13的内部。由于压气机出气管4内的空气流温度远低于废气流的温度，因此可以降低涡轮进口废气的温度。可利用调节单向阀11上阀门开启大小的方式来控制流经该阀门的空气流流量，使来自压气机2的引气量满足涡轮5进气降温要求即可，以尽量减小发动机进气量的损失。During the working process of the turbocharger, exhaust gas flows from the engine exhaust manifold interface 1 through the Venturi pipe throat 9 into the Venturi pipe 8, then enters the inside of the volute 13 through the turbine inlet 6, and then drives the turbine 5 And the coaxial compressor 2 rotates together, and then flows out through the turbine outlet 7; at the same time, the air enters the interior of the compressor housing 12 through the compressor inlet 3, and flows into it after being pressurized by the compressor 2 The air compressor outlet pipe 4 is discharged outwards. When the exhaust gas flows through the Venturi throat 9, the pressure decreases to be lower than the pressure in the outlet pipe 4 of the compressor due to the increased flow velocity. When the exhaust gas temperature exceeds the set value, the one-way valve 11 is opened, and the air flow in the compressor outlet pipe 4 will flow through the one-way valve 11 into the Venturi pipe throat 9, and then flow into the upper part of the Venturi pipe 8, and The exhaust gas from the engine exhaust manifold interface 1 enters the inside of the volute 13 through the turbine inlet 6 after being mixed. Since the temperature of the air flow in the outlet pipe 4 of the compressor is much lower than that of the exhaust gas flow, the temperature of the exhaust gas at the inlet of the turbine can be reduced. The air flow rate flowing through the valve can be controlled by adjusting the opening size of the valve on the one-way valve 11, so that the amount of bleed air from the compressor 2 can meet the cooling requirements of the intake air of the turbine 5, so as to reduce the air intake amount of the engine as much as possible Loss.
最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的宗旨和范围，其均应涵盖在本发明的权利要求范围当中。Finally, it is noted that the above embodiments are only used to illustrate the technical solutions of the present invention without limitation.
