The Southwest Research Institute (SwRI) is evaluating four new engines for its heavy-duty diesel engine benchmarking program, which already includes data from 10 previously studied ‘07 diesel models.

SwRI said it’s benchmarking a Cummins ISB diesel engine from a Dodge Ram pickup truck plus three heavy heavy-duty diesel engines – the Caterpillar C15, Cummins ISX and Volvo D13 . The program will focus on engine performance and fuel consumption associated with new exhaust emissions control technology and the use of ultra-low sulfur diesel (ULSD) fuel.

Mike Ross, a program manager in the SwRI’s engine, emissions and vehicle research division, said the data sets for these engines include a 200-point steady-state map of performance, injection timing, heat rejection, gaseous emissions and smoke.

He noted that within that matrix are 22 points that include high-speed cylinder pressure, heat release and particulate data; European Stationary Cycle (ESC) and U.S. FTP transient testing; constant-speed step load transient response tests; engine teardown; and cylinder head flowbench evaluations.
