Abstract
Liquid fuel is burned by feeding a mixture of a liquid together with liquid fuel which has been pre-gasified by rapid heating into a combustion zone. The liquid fuel is gasified by contact with a hot body. An internal combustion engine comprises a heated chamber having a heater, an air inlet and a fuel inlet. The mixture of gasified fuel and air is then introduced into the inlet manifold of the engine. Atomized liquid fuel and air is also inducted into the engine in a conventional manner, such as via a carburettor.
Claims9
An internal combustion engine, which comprises an inlet manifold (4) for inducting air into a cylinder constituting a combustion zone (2) for burning a liquid fuel;
- a heated chamber (14) having an outlet (22) connected to said inlet manifold and having an air inlet (16) and a liquid fuel inlet (20) for feeding part of the liquid fuel into the chamber;
- a heating means ( 28 ) in the chamber to convert said part of the liquid fuel to the gas phase, the heating means comprising a heated cup (26) heated to a temperature above the boiling point of the liquid fuel such that droplets of liquid fuel received in the heated cup are converted substantially instantaneously by contact therewith to the gas phase prior to being fed to the combustion zone.
A method of improving the fuel efficiency of an internal combustion engine which comprises inducting a part of the fuel in the gaseous form, the fuel having been gasified by feeding droplets of fuel into a cup heated to a temperature above the boiling point of the liquid fuel such as to convert the fuel substantially instantaneously by contact therewith to the gas phase;
- and the remainder of the fuel being in a non-gasified form, and burning the fuel in the combustion zone of the engine.
