Electric plug-in type hybrid power bus special engine and controlling method

Abstract

The invention discloses an electric plug-in type hybrid power bus special engine and a controlling method. The electric plug-in type hybrid power bus special engine solves the problems that in the prior art, the structure of an engine is complex, energy distribution according to the requirement cannot be realized, and emission and oil consumption are still high. The whole engine is compact in structure, high in power density, large in specific power and convenient to install and debug, and can be subjected to integrated comprehensive control conveniently. According to the scheme, the electric plug-in type hybrid power bus special engine comprises an engine body; an engine flywheel shell and an ISG generator shell are integrally arranged, and the engine body, a reverse damper, an ISG generator, an electromagnetic clutch and a driving engine are coaxially arranged.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a special engine for a plug-in hybrid electric bus and a control method. Background technique [0002] Energy shortages, environmental pollution, and climate warming have become the focus of the world and need to be solved urgently, and they are also huge challenges faced by the automobile industry and the energy industry; as a major contributor to oil consumption and carbon dioxide emissions, automobiles need revolutionary changes , Vigorously develop new energy vehicles and realize transportation energy transformation is an important way to achieve sustainable development of transportation. [0003] Since 2001, my country has started the R&D and industrialization of new energy vehicles. Continuously invest a lot of money to include new energy vehicles in the national "863" plan, "energy saving and emission reduction plan", "national science and technology supp...

Problems solved by technology

[0005] Although China has formed a world-class automobile industry, it is difficult for us to get rid of the dilemma of being constrained by others in key areas such as traditional power technology for a long time, especially the structural design of the engine and its control system for plug-in hybrid electric vehicles. The core technology is still in the hands of large international companies such as AVL, Bosch, and Woodward. The engine system based on plug-in hybrid electric buses that has been independently industrialized in my country has not been substantially developed and applied, and only traditional engines are directly applied to plug-in hybrid vehicles. For power buses, the energy distribution cannot be distributed according to needs, and the emissions and fuel consumption are still high without being optimized. This has brought great resistance to the power system and economic performance of plug-in hybrid electric buses.
