Engine test results with one of the five injectors for 1500rpm-2bar IMEP, 1500 rpm-3bar IMEP, and 1500 rpm-6bar IMEP. Sellnau reported results derived from testing on a single-cylinder research engine. For IMEP from 2 to 18 bar, engine-out NO x and PM emissions were below targets of 0.2 Sellnau et al.
