A vehicle exhaust system includes a mixer having an inlet that receives engine exhaust gases and an outlet to direct swirling engine exhaust gas to a downstream exhaust component. The mixer has a plurality of internal surfaces that come into contact with the engine exhaust gases. At least one of the internal surfaces has a coating comprised of a low-coefficient of friction material.

A hydro-diesel engine system, including: (a) a hydrogen gas supply and a liquid diesel fuel supply; (b) a bubbilizer configured to agitatedly mix some of the hydrogen gas into diesel fuel to form a mixture of small bubbles of hydrogen gas in the liquid diesel fuel which is then sent into a hydro-diesel engine; together with (c) a system for chemically mixing some of the hydrogen gas with the diesel fuel prior to the diesel fuel entering the bubbilizer.

Provided is a nano cell block module for homogenizing a solution with a high pressure. The nano cell block module for homogenizing a solution flowing through an inner part with a high pressure includes a first nano cell block 10a comprising at least two flowing passages 14a, 14b extending along a horizontal direction and guiding gaps 15a, 15b guiding the solution flowing along the at least two flowing passages 14a, 14b in a vertical direction; and a second nano cell block 10b comprising a third flowing passage 16 guiding the solution guided along the guiding gaps 15a, 15b in a horizontal direction.

A mixing funnel for mixing fluids is provided. In one embodiment, the mixing funnel includes a tray having a fluid inlet arranged to receive a primary fluid flow, and first and second fluid passages configured to receive primary fluid flow from the fluid inlet such that the flow is divided to flow along the first and second fluid passages. The first and second fluid passages can be arranged to direct the primary fluid flow to a mixing area. The tray can further include a fluid outlet arranged to receive the primary fluid flow from the mixing area and to deliver the fluid to a container.
