Abstract

Provided is a diesel vehicle automatic flameout device, which can realize that the diesel engine is electrified during working, and a flame switch rod can naturally return when the diesel engine is not working; automatic flameout can be realized after triggering a button and power off; and the flameout power source can be automatically closed after flameout.

Description

Technical field [0001] The invention relates to a flame-out device of a diesel locomotive engine, in particular to a device capable of automatically extinguishing the engine of a diesel locomotive. Background technique [0002] The engine flameout of the diesel vehicle is to connect the flameout switch lever on the engine to the pull wire button, and then the flameout is carried out by the pull wire. When the flameout is performed, the pull button must be pulled to wait for the flameout, so this flameout mode is very troublesome. In order to avoid trouble, people use a two-way flame extinguisher to cut off the power and turn off the flame, but this kind of flame extinguisher must be powered on when the engine is working to release the flameout switch lever to return. Turn the switch lever to the flame-off position to realize the purpose of power-off and flame-off. This two-way flame extinguisher has many deficiencies. When the motor is working, the flame extinguisher electr...
