The invention provides an apparatus for generating mist, comprising: a container adapted to accommodate a liquid, the container comprising an inlet for receiving an incoming fluid stream into the container, and an outlet via which an outgoing fluid stream exits the container; at least one agitating means arranged in the container for agitating the accommodated liquid to generate droplets of the liquid; wherein the agitating means is arranged to be driven by the incoming fluid stream, such that the generated liquid droplets are caused by the incoming fluid stream to form the outgoing fluid stream, and subsequently, exit the container. The invention also provides a system for generating mist, comprising: a plurality of the above described apparatuses, comprising at least a first apparatus having a first inlet and a first outlet, and a second apparatus having a second inlet and a second outlet; wherein the first outlet is adapted to be connected with the second inlet to thereby allow fluid communication between the first apparatus and the second apparatus.

A fuel heater and vaporizing system comprising an engine; a source of fuel coupled to the engine through a fuel supply line; multiple stages of thermal sources thermally coupled to the fuel supply line between the source of fuel and the engine, wherein the multiple stages of thermal sources are configured to heat the fuel; at least one catalyst system configured to supply a source of ions and H.sub.2 coupled to the fuel supply, and a sustainable water injection sub-system coupled to the engine, the sustainable water injection sub-system configured to inject water vapor into the engine.

A fuel conditioning system for an engine comprises a plurality of mixing vessels that include an input mixing vessel and an output mixing vessel, at least one inlet for receiving fuel and water into the input mixing vessel and at least one outlet for supplying the fuel and water from the output mixing vessel to the engine. A conduit system is arranged to transfer the fuel and water through each of the mixing vessels from the input mixing vessel to the output mixing vessel. Each of the mixing vessels comprises an internal chamber containing a plurality of nebulizing members. The nebulizing members are configured to rotate about a rotational axis extending through the internal chamber to nebulize the fuel and water therein. One or more magnets disposed in the internal chamber to attract ferromagnetic substances present in the fuel and/or water.

An intercooler may include an air-outlet tank, a condensate collector for collecting condensate separated off the intercooler, and a condensate line connected to the condensate collector via an entrance and that opens out into the air-outlet tank via an exit. There may be a pressure difference between the entrance and the exit of the condensate line during operation of the intercooler, and said pressure difference may allow differential-pressure-induced discharge of condensate from the condensate collector via the condensate line.
