Active Diesel Particulate Filters in California

Diesel Fuel is a dense fuel used in diesel engines. Because of its thick consistency, it requires more compression and takes longer to burn than standard gasoline, perfect for vehicles with larger, slower turning engines. They are usually used in larger vehicles such as trucks, buses, trains, and boats. They are also commonly used to power construction and farming equipment. Prior to being completely regulated in 2015, diesel fuel used in the United States contained high amounts of sulfur, known to produce air pollution emissions, detrimental to human health when released into the environment. Though lower concentrations of carbon monoxide are produced in diesel fuel engines, they are still significant producers harmful and should be filtered through a Diesel Particulate Filter (DPF).


These DPFs are responsible for filtering or trapping the soot particles contained in diesel exhaust. However, these filters need to be emptied and cleaned in order to perform at optimal levels. This process of cleaning is known as regeneration in which the accumulated soot is burned at a high temperature, removing the harmful components of the soot and only leaving ash. There are three types of regeneration: active, passive, and forced. Active filters manage the soot level and continuously clean the filter, passive filters rely on high exhaust temperature from the engine, and forced regeneration is achieved by elevating the exhaust temperature unnaturally.


Active Emissions Controls System:

These filters are programmed to monitor themselves, giving the user the peace of mind. Through the monitoring of the system’s condition, active technology is able to make a predictive analysis of when and at what rate to regenerate. It uses intelligent controls and sensors to activate the process right when the system needs it.


Rypos’ proprietary Active Diesel Particulate Filters’ technology uses systems which sense and predict when a cleaning is needed and trigger an electrical regeneration cycle before high back pressure from a clogged filter stresses the system. How is this done? The value and rate of increase in back pressure are measured and calculated using the systems microprocessor controller and sensor suite.
