"A DOC has the advan- tage that it is a non-capture, chemical conversion device and as such is not subject to performance sensitiv- ity associated with a low duty cycle." Engines that run hard at high loads generate enough heat to maintain a DPF, while machines that run at idle or at low rpms most of the time are better suited to DOCs. Deutz characterizes it's less than 75-horsepower en- gines as "space optimized" or "performance optimized," says Alec Hurley, at Deutz.
