The third of the modules comprises functional devices selectors for the supply of fuel and biofuel toward the engine depending on the parameters of temperature control and the level of biofuel, towards the pump injection cylinder engine and user control of conventional fuel in the auxiliary tank of the first module of biofuel, depending on the authorization sent from the control module installed in the conductor. The fourth functional modules comprises: (a) a device conductor of the biofuel level in the auxiliary tank of the first module; (b) a control device for the system for selection of conventional fuel and the activation of the use of biofuel towards injection pumps and to control the auxiliary tank in order to use with conventional fuel and control alarm; (c) devices to control the temperature of the medium heater and devices on the power of selecting the fuel/bus input and output signals and electrical power control devices earlier. The interconnection of the four modules control biofuel an engine is without feedback, by installing a system module and auxiliary tank conditioner features initials of biofuel for use; module of the auxiliary tank and the biofuel supply for conduction towards the filter module and that, supplying the module selector by conduction; (d) supply of conventional fuel in a tank, conduction toward a filter and the module selector; and (e) supplying the module selector, conventional fuel, and where appropriate, biofuel to the injection pumps, through a pipeline, controlling the entire system by the control module of the physical parameters of biofuel and the return of one's own fuel through a pipeline. For interconnecting modules control a biofuel motor feedback is a verified link between the module selector and release and the auxiliary tank. The provision of heat from a source is made by conducting to a release selector; providing heat from the module to the biofuel circuit verified by conduction which affect the conduction of biofuel, the filtering module, conduction supply and release associated with the deposit, with eventual return of the contributed heat. The method also comprises providing a catalyst-ionizer of fuel, installed in the module selector and located at the outlet of the fuel/biofuel towards the injection pump.
