DEVICE FOR THC REDUCING OF EXHAUST GAS IN CNG-DIESEL DUAL FUEL ENGINE SYSTEM

摘要

A device for reducing total hydrocarbon (THC) contained in exhaust gas in a CNG-diesel dual fuel engine system, includes: an engine providing power for the diesel and outputting exhaust gas due to operation; a MOC (Methane Oxidation Catalyst) oxidizing and discharging CH₄ contained in exhaust gas discharged from the engine; an exhaust valve disposed in a pipe connecting the rear end of the engine and the front end of the MOC, and discharging the exhaust gas produced by the engine; a first temperature sensor disposed at the front end of the exhaust valve and measuring the temperature of exhaust gas coming from the engine; a second temperature sensor disposed at the rear end of the exhaust valve and measuring the exhaust gas discharged from the exhaust valve and flowing into the MOC; and an exhaust valve control unit increasing the temperature of exhaust gas flowing into the MOC.
