Cummins PX-7 360 EV

The number in the name is the output in hp; suffixes such as H, EV or ST denote torque curves and calibrations. The register lists 22 versions with 195 to 360 hp at 2,400 to 2,600 rpm and 520 to 800 lb-ft (705 to 1,085 Nm) of torque between 1,600 and 1,800 rpm; certifications run from model year 2014 to 2026 – the three earliest entries with electronic direct injection and service class MHDD still belong to the previous ISB6.7 generation, the rest to the B6.7 generation from 2017 with the 'Vocational' application.

For fleet operators the kinship means parts, diagnostics and software are Cummins standard, any Cummins workshop can service the engine, and calibrations can be swapped within the certified power ratings.

On used engines the same checkpoints apply as for the B6.7: aftertreatment with particulate filter and SCR, EGR valve and cooler, injectors and the service history with the prescribed oil grades.
