Abstract
Previously indirect test methods were used to investigate Diesel engine combustion noise. Now digital signal analysis gives the possibility of determining it and its narrow band spectra directly. Such a method for direct evaluation of the combustion noise is described and the possibilities offered by it are shown. A single-cylinder direct-injection Diesel serves as a test engine. Steady-state as well as transient conditions of the engine are evaluated by the procedure.
