Abstract
A fuel cell electric vehicle includes a muffler deicing agent injection system composed of a deicing agent injector injecting a deicing agent, which is pumped by a deicing agent injection pump, from a deicing agent tank and is supplied to a deicing agent pipe. The muffler deicing agent injection system performs a muffler deicing agent injection logic to inject the deicing agent through operations of the deicing agent injection pump and the deicing agent injector by a controller under an ambient temperature satisfaction condition and a deicing agent injection satisfaction condition.
Claims17
A system for injecting a deicing agent in a muffler, the system comprising:
- a deicing agent tank storing the deicing agent therein;
- a deicing agent injection pump sending out the deicing agent from the deicing agent tank to a deicing agent pipe by pumping the deicing agent;
- and
- a deicing agent injector provided in the deicing agent pipe and injecting the deicing agent into an exhaust system.
A method for injecting a deicing agent in a muffler, the method comprising:
- an ambient temperature determining step of identifying an ambient temperature condition that requires deicing agent injection by a controller;
- a deicing agent injection preparing step of identifying an injectable deicing agent injection amount as a deicing agent injection condition;
- and
- a deicing agent injecting step of injecting the deicing agent, coming out from a deicing agent tank through pumping of a deicing agent injection pump and being supplied to a deicing agent pipe, in the deicing agent injection amount through a deicing agent injector, and making the deicing agent flow into the muffler through an inside of an exhaust pipe of an exhaust system in which hydrogen (H2) and water vapor generated by a chemical reaction of the hydrogen and oxygen flow as an exhaust gas.
