What does PF stand for?

It's high temperature sensors (HTS) are used with turbochargers, diesel particle filters and catalytic emissions filter systems which detect the loading rate of particle filters, providing data to the ECU to calculate when to start the regeneration process.

Do not be too judgmental on this little guy, he may seem small in size, but thanks to the advanced micro and nano particle filter, it more than compensates for its size.

The Austin Air Allergy Machine uses a large particle filter, a medium particle filter, activated military carbon cloth and then finally over thirty feet of HEPA filter.

The HEPA vacuum cleaner has a high efficiency particle filter that very effectively cleans the air that flows through the vacuum cleaner itself The HEPA vacuum cleaner has several advantages but you must first know about HEPA before you totally comprehend what it represents The HEPA vacuum cleaner has a high efficiency particle filter that very effectively cleans the air that flows through the vacuum cleaner itself.

And the diesel particle filter fitted as standard on the 103PS engine considerably reduces particulate emissions.

Experiment 1EF, performed in January 2005, was a 2 x 2 design in which each operation mode of the air cleaners was reimposed after exchanging used and new supply-air particle filters.

A good tutorial on non linear tracking using particle filter is given in [32] where the author illustrates that in highly non-linear environments particle filters give better performance than EKF.
