DEVICE FOR PREVENTING POLLUTION OF VEHICLE INJECTION NOZZLE

摘要

The present invention pertains to a device for preventing the pollution of a vehicle injection nozzle, which includes: a fuel supply section connected to a nozzle via a first pipe so as to supply fuel; a gas injection section connected to the nozzle via a second pipe so as to inject gas for removing the pollutants of the nozzle; a first valve disposed to the first pipe or the nozzle so as to be opened and closed for controlling the fuel supply of the fuel supply section; and a second valve disposed to the second pipe or the nozzle so as to be opened and closed for controlling the gas injection of the gas injection section. Therefore, compressed gas is injected into the injection nozzle so as to remove the pollutants from the interior of the injection nozzle, thereby preventing the pollution of the injection nozzle. In addition, the nozzle opening and closing section, which can open and close the injection portion of the injection nozzle, is disposed so as to prevent the pollutants from being introduced to the inside of the injection nozzle.
