Background

Throughout the development history of the generator set, the generator set is originally generated in the second industrial revolution period, and is manufactured by German Engineers Siemens in 1866, and is driven by a water turbine, a steam turbine, a diesel engine or other power machines to convert energy generated by water flow, air flow, fuel combustion or nuclear fission into functions and transmit the functions to a generator, and then the functions are converted into electric energy by the generator, wherein the electric energy is one of the most main energy sources of modern society. The internal combustion engine which converts heat energy generated by burning oil (gasoline or diesel oil) into mechanical energy is used as power to drive a generator which can convert the mechanical energy into electric energy to generate electric power, and the equipment is generally called an oil engine generator set. The generator set burning diesel oil is a diesel generator set, and is compared with a generator of a large-scale power plant; the diesel generator set has small volume and is integrated, can be conveniently moved when being mounted on a vehicle, is easy to operate, can be started at any time, generates electric energy with the same property as commercial power, and can directly drive electric equipment. Due to the characteristics, the diesel generating set has wide application in many departments of national economy and many aspects of social life; in areas where the mains power grid has not yet arrived or the power supply guarantee is not reliable, diesel generator sets are basically used for generating electricity to meet the requirements of electric equipment or life. Key hardware in the core fields of information-based society, such as networks, communication, media and the like, can not be separated from an uninterruptible power supply. The combined system of the UPS and the diesel generating set is the best choice for a power supply in the modern information field. Therefore, the diesel generator set also expands a new application range from the application range which is formed earlier. Compared with other types of generator sets, the diesel generator set has many advantages, and is a small and medium-sized power generation device. It has the advantages of flexibility, less investment, convenient start and the like, and is widely applied to various departments of communication, mining, road building, forest areas, farmland irrigation, field construction, national defense engineering and the like. Meanwhile, due to the structure of the diesel generator set, the defects which are difficult to overcome exist, such as large noise, large vibration, large volume and the like, and the purpose of the invention is to solve the problems existing in the diesel generator set.
