PURPOSE: A method for calculating control reference of a diesel engine is provided to stably calculate a control reference by using a mean value of combustion time point and an integral value of combustion pressure as a control reference value. CONSTITUTION: A method for calculating control reference of a diesel engine comprises next steps. The combustion pressure of the cylinder inside of the engine about a crank angle is measured by a combustion pressure sensor(S1). The motoring pressure is calculated about a crank angle(S2). The pure water combustion pressure is calculated about the crank angle(S3). The lowest combustion pressure spot is calculated as a combustion start point based on 'O' as top dead center of the crank angle(S4). The pure water combustion pressure is integrated about the time and integrated value(S5). The control reference value is produced through the integrated value integrating the combustion start point and the pure water combustion pressure(S6). |
