Cambustion’s diesel particulate generator (DPG) is a stand-alone test system for diesel particulate filters (DPFs). The instrument, which grew from a collaborative development program with Johnson Matthey, features several advantages over current engine-based DPF loading and testing: costly engine test beds are liberated from simple DPF loading cycles; more repeatable DPF load characteristics; and lower operating costs since loading can be run unattended. Standard DPFs can be loaded into the DPG either in production canning or as bare bricks using Cambustion-supplied adaptors. According to the company, the DPG uses computer-controlled combustion of diesel fuel (standard or reference fuels may be used) to produce engine-representative diesel soot at a carefully controlled rate, which may be increased above rates normally possible with engines.
