Abstract: A fuel injection method for decreasing diesel engine combustion noise can significantly increase the reduction rate of a pressure rising gradient of combustion pressure through even distribution of the total amount of fuel injection by operating an engine with single mixing injection where the total amount of fuel injected to a combustion chamber during one-stroke cycle of the engine is divided into double pilot injection amount and single main injection amount having different injection intervals, and double mixing injection where the total amount of fuel injection is divided into double pilot injection amount, post injection amount, and a main injection amount having different injection intervals. Therefore, the combustion noise of an engine, especially combustion noise in a 800-2 kHz frequency range can be reduced and Nox can be significantly improved.

Abstract: PURPOSE: A control method of an idle speed control throttle valve for a diesel vehicle is provided to improve the degree of freedom for the optimization of fuel efficiency, exhaust gas, and noise by adding the degree of freedom which allows a user to use as much EGR(Exhaust-Gas Recirculation)rate as a user desires.
