Problems solved by technology
When the traditional single-inlet turbocharger is used for an engine with an odd number of cylinders, the performance of the engine will decrease due to the exhaust interference between the cylinders, and the ignition interval angle is too large or the ignition interval angle is uneven, resulting in the turbocharger serious loss of efficiency

The double-inlet turbocharger structure comprises a pressing shell, a bearing body and a double-inlet turbine box, the bearing body and the double-inlet turbine box are connected with the pressing shell, and a gas circuit of a first inlet of the double-inlet turbine box is connected with an external bypass deflation mechanism and an external bypass pipe through a first flow channel of an inner cavity of the double-inlet turbine box; a gas circuit of a second inlet of the double-inlet turbine box is connected with an internal bypass deflation mechanism and an internal bypass hole through a second flow channel of an inner cavity of the double-inlet turbine box; the tail end of the external bypass pipe is connected with a turbine box outlet connecting pipe; the tail end of the internal bypass hole is connected with a turbine box outlet connecting pipe; and the tail end of the turbine box outlet connecting pipe is connected with an external exhaust pipeline. By the adoption of the double-inlet supercharger, the situation that the turbine air inlet pressure is low at a certain moment due to the fact that the interval angle is too large can be avoided, the situation that turbine air inlet fluctuates greatly due to the fact that the interval angle is not uniform can be avoided, and therefore the turbine efficiency is improved, namely the overall performance of an engine is improved.
Description
technical field [0001] The invention relates to the technical field of engine turbochargers, in particular to a double-inlet turbocharger structure. Background technique [0002] With the popularization of supercharged engines and the continuous tightening of emission standards, the engine displacement is required to be continuously reduced, and more and more engines with an odd number of cylinders appear one after another, and the layout of the engines is also developing in a variety of ways. Since the number of cylinders is odd, there is exhaust interference between cylinders, and at the same time, the engine ignition interval angle is uneven or the interval angle is large, which will lead to a serious loss of efficiency of the traditional single-inlet turbocharger. It is becoming increasingly difficult for devices to meet the requirements. Therefore, the supercharging technology of double-inlet turbo box will become one of the main development directions of future engine...
