Transient Engine Data

Total Number of Submissions: 1
Total Number of Downloads: 1042

Measurements or simulations of engine-out exhaust conditions (as close as possible to the exhaust valve) for well-defined transients, including FTP cycles. These typically include temperature, mass flow, and composition information versus time. Catalyst inlet measurements may also be included. Excel spreadsheets are preferred format.
