The invention relates to a variable speed ratio combined turbine system, which comprises a supercharger, a power turbine, a speed change mechanism and a transmission mechanism, wherein the speed change mechanism comprises a large speed ratio gear set engaged by a No.1 gear and a No.2 gear, and a small speed ratio gear set engaged by a No.3 gear and a No.4 gear; the No.1 gear and the No.3 gear are coaxially arranged on an output shaft of the power turbine; the No.2 gear and the No.4 gear are coaxially arranged on a transmission input shaft of the transmission mechanism; a combination sleeve capable of axially moving along the transmission input shaft is arranged between the No.2 gear and the No.4 gear; external teeth of the combination sleeve are matched with internal teeth of the No.2 gear and the No.4 gear; the combination sleeve is connected with a variable speed ratio control device through a shifting fork mechanism of the combination sleeve. When the variable speed ratio combined turbine system is used, the variable speed ratio control device judges the operation condition of an engine to control the combination condition of the combination sleeve according to a received engine speed and accelerator signal. The design is simple in structure and small in size, and the performance of the engine is improved.
Description
technical field [0001] The invention belongs to the technical field of engine exhaust gas energy recovery, and in particular relates to a compound turbine system with a variable speed ratio and its use method, which are particularly suitable for simplifying the structure, reducing the volume, and improving the performance of the engine. Background technique [0002] With the continuous increase of car ownership, the energy consumption of car engines, greenhouse gas CO 2 and pollutant discharge problems are becoming more and more prominent. The energy saving and emission reduction of automobiles have become the key issues to be solved urgently in the development of automobile industry. Improving the energy utilization rate of vehicle engines is one of the important measures to solve the problems of energy saving and emission reduction of vehicles. During the working process of the engine, only 30%–45% of the total energy of fuel combustion is used for the effective work of ...
