The present invention relates to a combination of components suitable to break down liquid fuels into short chain molecules and gaseous states of matter by heating and pressurizing the combustible/flammable liquids to the point where they phase change into a supercritical fluid, then releasing some fluid as needed into a vapor accumulation tank that has a lower pressure. This subsequent drop in pressure phase changes the fluid from a supercritical state into a consistent and safe gaseous state. From there, the fuel can be delivered to the engine via direct injectors, gaseous fuel carburetors, or a regulating valve such as a needle valve. Because gaseous fuels readily homogenize with intake air and oxidizers, the present invention allows any engine to cleanly, reliably, and consistent use any fuel without adjustment. This allows any engine to run off any combustible liquid, in effect creating the ultimate multifuel system.

Method of temperature management of fuel injected in internal combustion engines (1) applicable to said system, which takes into account the measurement of the fuel flow to be injected and one or more dynamic data of the engine demand level (1) in an immediate current instant, providing accuracy in the transformation of electrical energy into heat by controlling the fuel heating temperature and, consequently, great precision in the reduction of pollutant gases, without deterioration of the vehicle's energy balance (battery).

A preheating device for preheating the fuel of an internal combustion engine with a heating medium has a fuel transport device with a fuel inlet and a fuel outlet, and has a fuel transport channel connecting the fuel inlet and the fuel outlet. The preheating device also has a heating medium transport device with a heating medium inlet and a heating medium outlet, as well as a heating medium transport channel connecting the heating medium inlet and the heating medium outlet and/or at least one heating element. The fuel transport device and the heating medium transport device and/or the at least one heating element are in thermal contact with each other and thus form a heat exchanger via which a fuel transported in the fuel transport device can be heated by a heating medium transported in the heating medium transport device and/or by the at least one heating element.

Unclogging group for unclogging a filter of a pumping group for pumping diesel to an internal combustion engine, the unclogging group comprising: —a metering unit comprising an electromagnetic head and a control valve for controlling the diesel flow; —a filter associated with the control valve made at least in part of metallic material; —a temperature sensor for measuring the ambient temperature; —a control unit coupled to the temperature sensor; —an electrical circuit controlled by the control unit for supplying electrical current to the filter; wherein the control unit is configured so once received the starting input of the pumping group it compares the temperature measured by the temperature sensor with a threshold value, and if the temperature measured by the temperature sensor is less than the threshold value the control unit commands a delay of the starling of the pumping group of a period wherein the control unit supplies electrical current to the electrical circuit connected to the filter.
