摘要：
In the current study, experimental tests were conducted on a truck turbocharged diesel engine to investigate the mechanisms of combustion noise radiation and combustion instability during various starting schedules experienced in daily driving conditions, namely under cold and hot operations. To this aim, a fully instrumented test bed was set up to capture the development of key engine and turbocharger properties. Analytical diagrams are provided to explain the behaviour of combustion instability and noise radiation in conjunction with all relevant parameters, such as cylinder pressure and pressure spectrum, turbocharger and governor/fuel pump response.
