A fluid mixing device that includes a housing having a fuel inlet and at least one primary orifice positioned at the inlet, wherein the at least one orifice configured to disperse a stream of fuel into a plurality of fuel droplets. The plurality of fuel droplets contact a fuel impingement surface to break up the plurality of fuel droplets into a plurality of smaller secondary droplets and create a thin film of secondary droplets on the impingement surface. At least one pressurized air channel delivers an airflow into contact with the secondary droplets. The secondary droplets pass through a plurality of secondary outlet orifices to exit the housing. A size of the plurality of secondary droplets is reduced when passing out of the plurality of secondary orifices.

The invention relates to a fuel injector for injecting an over-enriched fuel and air mixture to the combustion chamber of an internal combustion engine, is characterised in that it comprises: a hydrocarbon liquid fuel spray nozzle, at least one supply of a gaseous carrier, a fuel mixing and evaporation chamber and an injector nozzle to the engine combustion chamber (C.C.), configured such that, during operation, liquid fuel is supplied and heated and compressed gaseous carrier are supplied to the fuel mixing and evaporation chamber of this injector through the spray nozzle, where they are mixed and evaporated as a result of elevated temperature, and the mixture of evaporated fuel with a hot gaseous carrier with low oxygen content thus formed reaches the combustion chamber (C.C.), through the outlet, wherein the gaseous carrier is air or, alternatively, flue gas, at elevated pressure and temperature and having a composition that prevents the initiation of flame combustion, and the gaseous carrier has oxygen content low enough to prevent the initiation of combustion, even under conditions of elevated pressure and temperature.

A cylinder liner for providing reduced oil carry-over in an air-assisted fuel injection system comprising an air compression piston wherein the cylinder liner and air compression system together in part define an air compression chamber, the cylinder liner comprising: an outer surface; and a plurality of projections on the outer surface: wherein the plurality of projections are arranged such that oil-laden air drawn up from an oil reservoir around the outer surface of the cylinder liner is forced into a labyrinthine path to increase the time the oil-laden air is in contact with the outer surface and increase the amount of oil adhering to the outer surface to minimise the amount of oil carry-over entering the air compression chamber.
