Active purge system equipped with water injection and operating methods for active purge system equipped with water injection

摘要

The present invention relates to a method of operating an active purge system equipped with water injection and an active purge system equipped with water injection, and a purging device for supplying boil-off gas from a fuel tank to an intake pipe, and a combustion chamber connected to the intake pipe. It includes a supply fuel injection nozzle, a water injection nozzle that injects water into the intake air flowing into the combustion chamber, a purging device, a fuel injection nozzle, and a control unit that controls the operation of the water injection nozzle, and the internal pressure of the intake pipe by a supercharger. Even if it is equal to or higher than this atmospheric pressure, it is possible to pressurize the boil-off gas by a purging device and introduce it into the intake pipe.Since the liquid injection nozzle injects water into the intake, it is possible to reduce the heat of combustion generated during combustion, and as a result, NOx An active purge system with water injection and a method of operating an active purge system with water injection are provided.
