- Gasoline Particulate Filter - an overview | ScienceDirect Topics
Gasoline particulate filter The GPF may be either a separate unit or canned together with the TWC It has a honeycomb structure that is usually made from a synthetic ceramic “cordierite ” While the porosity of the GPF is higher than that of a DPF, because its substrate is lighter, and this allows the gas to move more easily, it also means the GPF is more fragile than a DPF As in DPF there
- Gas-phase fractionation DDA promotes in-depth DIA phosphoproteome . . .
We present the use of gas-phase fractionation (GPF) DDA data to improve the depth of library-free DIA identification for the phosphoproteome, called GPF-DDA hybrid DIA This method fully utilizes the remnants of samples post-DIA analysis and leverages both library-based and -free DIA database searching
- China 6 EGR gasoline vehicles without a GPF may struggle to meet the . . .
EGR-gasoline vehicles without GPF have a high risk of failing the potential SPN10 limit
- Regeneration performance and particulate emission characteristics . . .
Ash in the GPF affects filtration efficiency, flow resistance, and regeneration efficiency (Sgro et al , 2012, Überall et al , 2015) Many experimental and numerical studies have been conducted to understand the chemical composition of ash and the ash’s effect on filter performance Seong et al (2021) showed that regardless of formulated oil type and particle size, Ca, P and C were always
- Exhaust non-volatile particle filtration . . . - ScienceDirect
The GPF is a deep-bed filter and the filtration process are regarded as a physical process which is mainly influenced by the flow field [31] At high exhaust flow rate conditions, the flow rate of the exhaust gas through the porous wall is also high, resulting in low filtration efficiencies
- The possibilities of GPF Surface modification in the aspect of micro . . .
GPF regeneration is a process in which organic compounds collected on the surface are combusted to carbon dioxide and steam One of the main organic components is soot, which is almost a non-reactive substance, therefore high temperature and oxygen access are required
- Exhaust non-volatile particle filtration . . . - ScienceDirect
The particle filtration characteristics of the TWC and GPF are compared, and the influencing factors and filtration mechanism are analyzed The results show that the TWC have obvious filtration effects on exhaust particles, and the total filtration efficiency is 20–35% for the TWC compared to 70–85% for the GPF
- Towards zero pollution vehicles by advanced fuels and exhaust . . .
The gasoline car without the GPF emitted relatively high concentrations of particles compared to the other technologies but the implementation of the GPF decreased particle emissions, and the potential to form secondary aerosols in atmospheric processes
