This review paper summarizes major developments in vehicular emissions regulations and
technologies (light-duty, heavy-duty, gasoline, diesel) in 2012. First, the paper covers the …

Ash accumulation in the channels of ceramic, honeycomb-type particulate filters is controlled
by several key parameters, which are the focus of this study. Ultimately, it is the formation of …

Diesel particle filter (DPF) is widely considered as the most effective approach to reduce and
control particle matter (PM) emissions. However, with the continuous accumulation of …

The formation and transport processes governing the build-up of incombustible ash deposits
in diesel particulate filters (DPF) are influenced to a large extent by the filter's operating …

The impact of inlet particle properties on the filtration performance of clean and particulate
matter (PM) laden cordierite filter samples was evaluated using PM generated by a spark …

The investigation of physicochemical characteristics of metal oxide ashes, deposited on a
diesel particulate filter, was conducted using electron microscopy, energy dispersive …

While biodiesel is one of many necessary steps forward in a cleaner transportation future,
alkali metal residuals, including Na and K (in the form of oxides, sulfates, hydroxides, and …

Accumulation of lubricant and fuel derived ash in the diesel particulate filter (DPF) during
vehicle operation results in a significant increase of pressure drop across the after-treatment …

Diesel Particulate Filters (DPF) are a key component in many on-and off-road aftertreatment
systems to meet increasingly stringent particle emissions limits. Efficient thermal …

Size-resolved particle mass and number concentrations were obtained from different
operating conditions using a spark-ignition direct-injection engine and a heavy-duty diesel …
