Objectives<br />
“turbo-lag”, “compresso-lag” or “?-lag”?<br />
• Define engine <strong>transient</strong> processes, detailed at the<br />
components level identify the critical processes in<br />
subsystems responsible for delaying acceleration<br />
• Assess the relative contribution <strong>of</strong> each particular process<br />
through simulation <strong>and</strong> experiment <strong>and</strong> establish<br />
interrelations<br />
• Identify patterns for undesirable response effects during<br />
<strong>transient</strong>s by observing consistent trends during<br />
acceleration steps <strong>and</strong> analyzing evolution <strong>of</strong> various<br />
processes <strong>and</strong> parameters in the sequence <strong>of</strong> cycles<br />
• Elaborate a more consistent definition for concepts such as<br />
“turbolag”
