Abstract
The invention relates to a method for controlling the starting of a diesel engine of a locomotive through a computer, comprising the following steps of: detecting the pressure of a lubricating oil system of the diesel engine; when the oil pressure of the lubricating oil system reaches a lubricating oil pressure set value and starting interval time meets an interval time set value, starting a motor to work; detecting the rotating speed of the diesel engine; and when the rotating speed of the diesel engine reaches a starting rotating speed set value or the working time of the started motor exceeds a starting time set value, starting the motor to stop working. Thus the invention prevents manual misoperation, the excessive discharge of a storage battery and the overheating of the started motor and meets the requirements for safety, reliability, easy and convenient operation and energy saving.
Description
Technical field
The invention belongs to the internal combustion locomotive technical field, relate in particular to a kind of computer control locomotive diesel engine starting method.
Background technique
When starting diesel engine of locomotive, take place to make diesel engine when lubricant oil does not reach authorized pressure, open the phenomenon of machine in the past, cause the diesel engine moving element to damage because of insufficient lubrication owing to carelessness of driver through regular meeting.Moreover, because people's reaction is slower, usually can cause diesel engine to light a fire successfully after, do not unclamp start button yet, make starting contactor still be in closed state; When the diesel engine igniting was not successful, the driver tended to pin start button, prolonged starting time, perhaps made twice startup too short at interval.These all can cause storage battery too to discharge, and actuating motor is overheated.
Summary of the invention
Purpose of the present invention overcomes the deficiency of above-mentioned prior art exactly, and a kind of easy and simple to handle, safe and reliable, computer control locomotive diesel engine starting method of saving the energy is provided.
The objective of the invention is existing like this: a kind of computer control locomotive diesel engine starting method is characterized in that taking following steps:
A. system initialization;
B. detect whether enabled instruction is arranged,, then repeat this step if do not have; If have, enter next step;
C. start lubricating oil pump to diesel engine lubrication delivery and timing, fuel pump is supplied with fuel oil to diesel engine;
D. whether the detection startup lubricating oil pump operating time reaches primer pump oil time set value, if do not reach, then returns step c; If reach, then enter next step;
E. detect the diesel engine lubricating oil pressure and whether reach the lubricating oil pressure setting value,, then enter step k if do not reach; If reach, then enter next step;
F. actuating motor drives diesel engine and rotates also timing;
G. detect diesel engine speed and whether reach the startup speed setting value,, then enter step k if reach; If do not reach, then enter next step;
H. whether detect the actuating motor operating time above setting value starting time,, then return step g if do not surpass; If surpass, then enter next step;
I. actuating motor, start lubricating oil pump and cut-out of fuel pump, count enable blanking time simultaneously;
J. detect to start whether reach the setting value blanking time blanking time,, then return step I if do not reach; If reach, then return step b;
K. start and finish.
After adopting the solution of the present invention, have only the oil pressure of oil system to reach the lubricating oil pressure setting value and start and satisfy blanking time blanking time during setting value, actuating motor could be worked; And diesel engine speed reaches when starting speed setting value or the actuating motor operating time surpasses starting time during setting value, and actuating motor all can quit work.Will avoid artificial misoperation like this, avoid that storage battery too discharges, actuating motor is overheated, realize requirement safe and reliable, easy and simple to handle, that save the energy.
Description of drawings
Accompanying drawing 1 is the system principle diagram of the embodiment of the invention.
Accompanying drawing 2 (a) and (b) are the flow chart of the embodiment of the invention.
Embodiment
