Low load operation system of dual fuel engine and low load operation using the same method

摘要

The present invention relates to a low-load operation system for a dual-fuel engine and a low-load operation method using the same. More specifically, the present invention relates to a dual-fuel operation engine that improves energy efficiency by eliminating incomplete combustion of fuel in a dual- To a low-load operation system for a dual-fuel engine which enables stable operation and a low-load operation method using the same. To this end, there is provided a system for low-load operation of a gas engine or a dual fuel engine, comprising: an exhaust temperature sensor installed in each cylinder, for measuring a temperature of exhaust gas discharged from a cylinder; A pilot fuel injector provided for each cylinder, for finely controlling and injecting diesel fuel; And a control unit for receiving the temperature value measured by the exhaust temperature sensor and calculating and determining the injection setting in which the pilot fuel injector injects the fuel into the respective cylinders through the received temperature value, A low-load operation system and a low-load operation method using the same are provided.
