Abstract:
A liquid injector has an injector body provided with an injection passage which is formed by the cavity between the inner wall of the injector body and a needle and the cavity in a hole located in the wall of the injector body. The liquid injector has a spherical, hollow porous element which extends beyond the injector body and is formed by a semi-sphere which is fixed to the injector body and closes off the injection passage. The wall thickness of the porous element is not the same throughout. In the middle the wall is thinner than near the edge, so that during the injection action the fuel vapour has the shape of a semi-ellipse.
Abstract:
The present invention relates to a liquid fuel composition comprising a mixture of hydrocarbons and a cyclic hydrocarbon compound that suppresses the emission of soot particulates. The present invention also relates to a method for reducing the emission of soot particulates in the exhaust gases of an internal combustion engine. It is desirable for the cyclic hydrocarbon compound to contain one or more oxygen atoms.

Abstract:
An air inlet system (10) for an internal combustion engine (200) is provided. The air inlet system comprises an air intake port (20), an air output port (30) for providing air for a combustion chamber (202) of the combustion engine (200), and a turbine (40). The turbine (40) is situated in between the air intake port (20) and the air output port (30) for turning kinetic energy of an airstream from the air intake port (20) to the air output port (30) into mechanical energy. The turbine (40) comprises at least one adjustable vane (48) for controlling an air flow resistance of the turbine (40). An electrical generator (46) is coupled to the turbine (40) for converting the mechanical energy into electrical energy. A controller (60) controls a rotational speed of the turbine (40) by controlling a quantity of electric power generated by the electrical generator (46), the controller (60) being configured to adapt the rotational speed of the turbine (40) to the air flow resistance of the turbine (40) in such a way that a substantially optimal turbine efficiency is obtained.
