ABSTRACT:
A diesel engine may be stably controlled without an exhaust gas temperature at an upstream side of a turbocharger, by a method for controlling a diesel engine that includes: detecting an engine rotation speed; detecting or estimating a lambda value; estimating an exhaust gas temperature at an upstream side of a turbocharger by using relationship between the lambda value and an exhaust temperature; determining whether the estimated exhaust gas temperature exceeds a first predetermined reference value; and limiting an engine output power and/or regeneration of a CPF when the estimated exhaust gas temperature exceeds the first predetermined reference value.
