Internal combustion locomotive engine start-stop system and engine start-stop control method

Abstract

The invention relates to the technical field of diesel locomotive engine starting and stopping, in particular to a diesel locomotive engine starting and stopping system and an engine starting and stopping control method. Comprising a start-stop controller, an engine stop trigger module, an engine start trigger module, a vehicle body electrical control system, a storage battery, a generator and a starter, and the start-stop controller is used for judging whether a current vehicle needs to activate an engine start-stop control mode or not and conducting activation operation; the engine shutdown triggering module is used for detecting shutdown triggering data; the engine starting triggering module is used for detecting starting triggering data; the vehicle body electrical control system is used for connecting all the modules and mechanical parts to the start-stop controller. The designed system is relatively independent in structure, durability and reliability are guaranteed, and economic benefits are improved; automatic control is carried out through the start-stop controller, it is guaranteed that the system is safely and stably started and takes effect, the possibility of breakpoint selection errors and missed selection is reduced to zero, and reliability and ductility are improved.

Description

technical field [0001] The invention relates to the technical field of engine start-stop of a diesel locomotive, in particular to an engine start-stop system and an engine start-stop control method of a diesel locomotive. Background technique [0002] Heavy-duty rail vehicles mostly undertake construction and rescue tasks in urban rail transit operations. Heavy-duty rail vehicles must have their own power—an internal combustion engine. However, new energy and clean energy have not been applied on a large scale in heavy-duty rail vehicles. Relying on related technological breakthroughs. At present, there are no effective measures in the heavy rail vehicle industry at home and abroad to reduce the carbon emissions of internal combustion engines. Therefore, in combination with the working conditions of heavy-duty rail vehicles, adding an automatic start-stop system to the internal combustion engine of heavy-duty rail vehicles to reduce energy consumption and carbon emissions i...

AI Technical Summary

Problems solved by technology

[0003] At present, no mature application of the engine start-stop system has been found in the domestic heavy-duty rail car market. At present, there are the following technical difficulties: if there is a problem with the breakpoint selection, the engine may not start or the engine start-stop failure may occur; there are many prerequisites for the use of the start-stop system , if the sequence of conditions is wrong or the logic is wrong, it will cause the vehicle to fail to start or the starting system to fail
