Problems solved by technology

[0003] However, after two engines are connected in series, the load distribution ratio of each engine is highly random, and the output power of the two engines has a large gap, which will lead to excessive torsional vibration of the engine and unstable output power.

Abstract

The invention relates to the technical field of internal combustion engines, and discloses a series engine control system and power system which comprises a control unit and a pressure sensor. The pressure sensors are arranged at fuel pump units of all the engines respectively and used for obtaining pressure signals of all the fuel pump units, and the control unit is connected with the pressure sensors and used for obtaining all the pressure signals so as to determine the oil quantity output by all the fuel pumps according to the pressure signals, so that the output power of all the engines is determined. The control unit is further connected with all the fuel pump units and used for controlling the accelerator opening degree of all the engines till all the pressure signals meet the preset conditions, and therefore it is guaranteed that the output power of all the engines is the same. Therefore, according to the scheme, the output power information of the engines is obtained by detecting the pressure signals of the fuel pumps of the series engines, the output power of the engines is the same by adjusting the output oil quantity of the fuel pumps, and therefore it is guaranteed that the torsional vibration and the output power of the series engines are stable, and the reliability standard is met.

Description

technical field [0001] The invention relates to the technical field of internal combustion engines, in particular to a series engine control system and a power system. Background technique [0002] With the advancement of technology, the performance of mechanical equipment has been greatly improved, and the power required by mechanical equipment has also increased. Since the engine power designed and produced by the existing technology has an upper limit, and the cost of a high-power engine is much higher than that of a low-power engine, even if the power of the engine is doubled, the cost increases several times, usually two identical engines are used. The tandem form replaces the more powerful engine to achieve the purpose of powering heavy machinery. [0003] However, after connecting two engines in series, the load distribution ratio of each engine is highly random, and the output power difference between the two engines is large, which will lead to excessive torsional ...
