<P>PROBLEM TO BE SOLVED: To provide a state monitoring operation method for diesel engine, capable of calculating a recommended value for the most economic operation in accordance with a state of the engine, performing the economic operation based on the recommended value, and reducing the operation costs while precisely grasping a sliding state of a piston ring relative to a cylinder liner, a combustion state, and a cylinder input air temperature state during the engine operation. <P>SOLUTION: A plurality of measurement values related to a sliding state of a piston ring, a combustion state, and a cylinder input air temperature state of a diesel engine 10 are stored in a storage area of a computer 20. A state determination is performed for each measurement value to calculate each state index f. On the basis of it, a recommended value of oiling rate of lubrication oil for the cylinder, a recommended value of fuel injection timing, and a recommended value of a cylinder input air temperature required for the optimum economic operation are calculated. Control signals matching with the recommended values are output from a control device 30 to the diesel engine 10 while presenting the recommended values to an operator. <P>COPYRIGHT: (C)2012,JPO&INPIT |
