Accompanying drawing explanation
Fig. 1 is present system structural representation.
Embodiment
Double fuel locomotive of the present invention comprises motor, engine electric spray controller, LNG tank, and described switched system comprises feed flow cut-off valve, vaporizer, safety valve, air inlet electromagnetic valve, diffusion valve, methane detection system, locomotive microcomputer.
LNG tank, feed flow cut-off valve, vaporizer are connected in turn by LNG pipeline, and vaporizer safety valve, air inlet electromagnetic valve, diffusion valve, motor are connected in turn by methane gas pipeline.
The methane detection main frame that methane detection system comprises the some methane transducers be distributed on locomotive, communicates to connect with each methane transducer.
Described locomotive microcomputer is connected with engine electric spray controller, methane detection main frame, motor plc communication.
Engine electric spray controller is used for sending double fuel enable signal to microcomputer.
Described locomotive microcomputer for control feed flow cut-off valve and air inlet electromagnetic valve break-make, receive double fuel enable signal, detect locomotive and whether meet double fuel service condition, send dual fuel mode switching signal to transmitter PLC.
Each methane transducer for detecting the methane leakage concentration of its position, and sends testing result to methane detection main frame.Methane transducer is distributed on locomotive, is generally between electric equipment compartment and/or motor and/or chilling room and/or tank car, or other easily produce places of methane leakages.
Methane detection main frame is used for the difference according to methane leakage concentration, carries out different warnings.
Certainly, described system must comprise power supply, and on general locomotive, equipment use is Ac, a storage battery and an inverter can be utilized to realize, or directly use Ac.
Below the switching mode of native system is described.
Comprise the workflow entering dual fuel mode and the workflow exiting dual fuel mode,
The workflow entering dual fuel mode comprises the steps:
Step one: driver selects dual fuel mode.
Step 2: locomotive loads.
Step 3: locomotive microcomputer detects the double fuel service condition whether meeting and pre-determined, and if so, then carries out step 3, as otherwise repeat this step.
Step 4: engine electric spray controller sends double fuel enable signal to locomotive microcomputer.
Step 5: locomotive microcomputer controls to open feed flow cut-off valve, and locomotive enters dual fuel mode.
The workflow exiting dual fuel mode comprises the steps:
Step one: driver selects to exit dual fuel mode.
Step 2: locomotive microcomputer controls to close feed flow cut-off valve, stops continuing outside feed flow from LNG tank.
Step 3: locomotive microcomputer controls to close air inlet electromagnetic valve, opens automatic relief valve.
Step 5: microcomputer sends to motor and exits dual fuel mode switching signal.
Step 6: motor receives and exits dual fuel mode switching signal.
Step 7: motor exits dual fuel mode, enters pure fuel oil operating mode.
Preferably, after step 2 performs, time delay performs step 3 after a period of time again.After step 6 performs, time delay a period of time performs step 7.As far as possible the object of time delay has been burnt by the methane gas gasified in locomotive air pipe, allows residual methane gas as far as possible few in air pipe, reduces possibility and the amount of leakage of later stage methane leakage.It is 30s that the present embodiment arranges delay time, and this numerical value can better residual methane gas less, and can not the time oversize, lower efficiency.
As kept in dual fuel mode process at motor time delay 30s, non-time delay has not met double fuel service condition (as locomotive unloading to 30s motor, gaseous-pressure is less than 0.5bar), then motor exits dual fuel mode at once, locomotive microcomputer controls the air inlet electromagnetic valve before killing engine, and opens diffusion valve; As loine pressure after now vaporizer is greater than 1.4MPa, then safety valve action gets rid of excess pressure.
When locomotive failure unloads, microcomputer cuts out the feed flow cut-off valve on LNG pipeline, the air inlet electromagnetic valve before motor automatically, and stop for liquid/gas, open diffusion valve, motor exits dual fuel mode simultaneously, enters pure fuel oil operating mode.
When CH_4 detection device detects that methane concentration reaches lower bound--during warning signal (25%LEL) alarming value, microcomputer controls to cut out the feed flow cut-off valve on LNG pipeline, stop feed flow, air inlet electromagnetic valve before time delay 30s de-activation engine, open diffusion valve, motor exits dual fuel mode, enters pure fuel oil operating mode.
When locomotive receives emergency-stop signal (racing of the engine, crankcase pressure be high, reveal methane concentration is greater than 50%LEL), emergency shutdown action implemented by locomotive.During locomotive emergency shutdown, microcomputer unloads, and gives engine emergency stopping signal simultaneously, and steam supply valve before cutting off LNG liquid supply valve and motor, open diffusion valve X6 simultaneously and diffuse in vent external air by methane gas in pipeline before motor, motor is shut down.
When locomotive rotating speed is less than setting value, the present embodiment is set to≤580rpm, and microcomputer controls to turn off feed flow cut-off valve, cuts off LNG feed flow, and as engine speed≤380rpm, turn off air inlet electromagnetic valve, now motor exits dual fuel mode.Microcomputer controls automatic relief valve events simultaneously, by emptying for methane gas in pipeline between feed flow cut-off valve to motor, avoids engine exhaust port blast accident occurs.
It should be noted that EFI controller provides double fuel enable signal and need meet the following conditions:
1. electric injection system alarm free.
2. engine oil gate signal is not less than specified value.
3. engine speed is not less than specified value.
