    Abstract: Methods for generating and applying coatings to filters with porous material in order to reduce large pressure drop increases as material accumulates in a filter, as well as the filter exhibiting reduced and/or more uniform pressure drop. The filter can be a diesel particulate trap for removing particulate matter such as soot from the exhaust of a diesel engine. Porous material such as ash is loaded on the surface of the substrate or filter walls, such as by coating, depositing, distributing or layering the porous material along the channel walls of the filter in an amount effective for minimizing or preventing depth filtration during use of the filter. Efficient filtration at acceptable flow rates is achieved.

    Abstract translation: 为了减少大的压降而产生和涂覆多孔材料的过滤器的方法随着过滤器中积聚的材料以及过滤器表现出减小和/或更均匀的压降而增加。 过滤器可以是用于从柴油发动机的排气中除去诸如煤烟的颗粒物质的柴油颗粒捕集器。 诸如灰分的多孔材料被装载在基材或过滤壁的表面上，例如通过沿着过滤器的通道壁涂覆，沉积，分布或分层多孔材料，其量可以有效地在使用过程中最小化或防止深度过滤 过滤器。 实现了在可接受的流速下的高效过滤。

    Abstract: The use of porous materials in the dead space of reciprocating engines is described. The porous material can be used to condition the cylinder gases. In addition, the porous material may include a catalyst for driving chemical reactions. The catalytic process occurs on the porous material, not on the cylinder walls. The engine parameters (number of cycles, number of strokes per cycle, compression ratio, engine speed, cylinder volume, valves timing, gas composition, pressure and temperature) are adjusted to optimize gas compression or chemical reactor performance.

    Abstract: A system and method for controlling the operation of a particulate filter is disclosed. The objective of this control system is to manipulate the properties and spatial distribution of contaminant material accumulated in filters to reduce filter pressure drop and associated deleterious impacts of the contaminant material on filter performance.
