Diesel? Particulate Filter? Why? When and What for?

Exhaust particulates, whether from diesel or gasoline-fueled engines, form a very complex aerosol system. Despite a considerable amount of basic research, a full understanding of exhaust particulate matter - PM, its physical and chemical properties, and its effect on human health and the environment is still lacking.

Particulate matter—most commonly associated with diesel engines—is responsible for the black smoke traditionally associated with diesel-powered vehicles. Diesel particulate matter emissions are usually abbreviated as PM or DPM, the latter acronym being more common in occupational health applications. The existing medical research suggests that the PM is one of the major harmful emissions produced by diesel engines. Diesel particulate matter is subject to diesel emission regulations worldwide. Diesel PM and NOx are the primary focus of diesel emission control technology.

In today's post, we will tell you everything we know about Diesel Particulate Filter, what does it mean and why it’s important to have such. 

Diesel Particulate Filter - DPF - filtrates the particle from being released into the air. The DPF has been used by many diesel-fueled trucks since 2007.

Today’s tractors run cleaner than ever due to the increasing emissions standards from the EPA. Yanmar tractors, for example, can meet these increasing standards thanks to the “build in” DPF. This device catches and traps soot or unburned fuel to be burned out at a later time such as while the tractor is carrying a heavy load or undergoing a regeneration cycle. The soot is burned out anytime the exhaust temperature is elevated.

Regeneration temporarily changes the operating settings of the engine to generate extra-high temperatures in the DPF to combust and consume the engine exhaust products or pollutants that accumulate in the DPF during normal engine operation. 

While the EPA mandates the DPF technology lasts 3,000 hours, it has been proven that the DPF lasts exponentially longer contributing to a long, clean, and happy life for your tractor. After about 3,000 hours, the DPF will need to be cleaned by first being removed from the tractor then sent off to our Yanmar Reman program where it will be cleaned by being “baked” in an oven to remove the excessive ash load - the remains after the soot has been burned out during regen. A Diagnostic Trouble Code or DTC is what indicates that the ash build-up in DPF too high.

Diesel Particulate Filter is a very smart piece of technology and a clean contribution to your Yanmar tractor. Thanks to the DPF, your tractor is kept clean as well as your to-do list.
