Unlike a catalytic converter which is a flow-through device, a DPF retains bigger exhaust gas particles by forcing the gas to flow through the filter; however, the DPF does not retain small particles and maintenance-free DPFs break larger particles into smaller ones.  There are a variety of diesel particulate filter technologies on the market.
pyrolysis ofthe tetramethylsilane ordiethylsilane produces silicon carbide. In a departure from the earlier system, we have added a small fan with a brushless DC motor inside the chamberto provide forced convection to the deposition area similar to that in a flowing gas system.

Porous silicon carbide (SiC) membranes are proposed for filtration applications for produced water in the oil and gas industry. Key advantages of SiC membranes include their chemical resistance, high temperature stability and low fouling behavior.
Microwave-assisted organic synthesis in nonpolar solvents is investigated utilizing cylinders of sintered silicon carbide (SiC)a chemically inert and strongly microwave absorbing materialas passive heating elements (PHEs). These heating inserts absorb microwave energy and subsequently transfer the generated thermal energy via conduction phenomena to the reaction mixture.
· Thin-film thermocouples were sputtered directly onto the flat rake face of a commercially available tungsten carbide cutting insert using micromachined stencils and the measurement junction was coated with a protective layer to obtain temperature data 1.3 μm below the tool–chip interface. Oblique interrupted cutting tests on AISI 12L14 steel ...
A varistor is an electronic component with an electrical resistance that varies with the applied voltage. Also known as a voltage-dependent resistor (VDR), it has a nonlinear, non-ohmic current–voltage characteristic that is similar to that of a diode.In contrast to a diode however, it has the same characteristic for both directions of traversing current.
Silicon Carbide Technology Breakthrough Silicon carbide (SiC) is a semiconductor material under rapid development for use in power electronic (PE) systems due to its unique material and electronic properties. SiC potentially offers several advantages over conventional silicon (Si) for use in PE devices. Comparatively, individual

· Some service technicians may be surprised to learn that the silicon carbide element of a hot surface igniter (HSI) can be handled without damage. However, it is better and safer to handle the igniter by the ceramic holder. The myth that the silicon carbide tip cannot be handled because body oils cause contamination is untrue.
key element is the flow channel insert (FCI) made of a silicon carbide composite (SiC f /SiC), which serves as electric and thermal insulator.
