Problems solved by technology

[0005] However, in the above scheme, the water vapor medium is easy to corrode the built-in driving device, and the use of steam medium as the driving method will lead to a slow speed-up process, which cannot adapt to complex urban roads and speed-limited expressways. Therefore, a hybrid power device is urgently needed Carry out driving, improve the problem of power speed-up process in the above scheme, retain the advantages of environmental protection and heat energy utilization

Abstract

The invention discloses a power system of a hybrid electric vehicle. The power system comprises a driving system and a transmission system, wherein the power system is characterized in that the driving system comprises a motor driving system and a fuel oil driving system which are connected in series, a waste heat recovery system is arranged between the fuel oil driving system and the transmissionsystem, the waste heat recovery system comprises an energy storage device and an air cylinder for receiving waste gas heat of an engine, and the energy storage device is in power connection with theair cylinder. The power system is advantaged in that a problem of power acceleration in the prior art is solved, and the advantages of environmental protection and heat energy utilization rate are reserved.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to a power system of a hybrid electric vehicle. Background technique [0002] An engine is a device that can convert other forms of energy into mechanical energy, including internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, etc. The internal combustion engine is a heat engine that directly converts the heat energy released into power by burning fuel inside the device. The external combustion engine is a heat engine that uses fuel combustion to heat the circulating working fluid to convert heat energy into mechanical energy. [0003] At present, due to the structure of the external combustion engine itself, it has a large volume and low kinetic energy conversion rate. People often choose internal combustion engines to replace external combustion engines, but internal comb...
