Diesel particulate filter - Wikipedia

With an optimal diesel particulate filter (DPF), soot emissions may be decreased to 0.001 g/km or less. The quality of the fuel also influences the formation of these particles. For example, a high sulfur content diesel produces more particles. Lower sulfur fuel produces fewer particles, and allows use …

Vacuum Breaker for Softener/Filter on Input or Output

Oct 29, 2015· Vacuum Breaker for Softener/Filter on Input or Output? Most softeners/filtration systems have the inlet/outlet tied together internally during the regeneration cycle unless the system is designed with a no hard water bypass valve etc, but even then, most of those system designs will have multiple tanks so only the valve that is in

What is Regenerative Braking? (with pictures)

Jul 30, 2019· Why use this complied breaking system? Why not just use a motor (generator) that pushes on the wheel whenever brakes are applied instead of using it to stop the car? Doing this you would not be using energy from the motor to slow the car, you would be able to use it when braking at high speeds and it is much simpler to build.
