    Abstract: A method for decreasing burning noise though improving maximum pressure by multi point injection in a field of idle is provided to decrease maximum value for combustion pressure by performing multi point injection while dividing the number of injection into RPM of an engine. A method for decreasing burning noise though improving maximum pressure by multi point injection in a field of idle comprises the step of making difference in limited value for the number of injection according to RPM of a diesel engine by detecting the RPM when the diesel engine performs idle rotation and low speed-load rotation. The method further includes the steps of starting engine(S1), operating the engine(S2), and determining the RPM of the engine(S3). In the step of determining the RPM, when the RPM is less than 1000, pilot injection is performed at least three times(S4) and when the RPM is more than 1000, the pilot injection is performed twice(S5).
