Patent ID: 8146575

Claim:
A system for supplying LPG/methane, ammonia, or gas as an injection fuel for a petrol or diesel engine having an electronic control unit, said system comprising: a fuel tank configured to contain LPG/methane, ammonia, or gas as the fuel; a line for delivery the fuel from the fuel tank; a valve controlling flow of fuel from the fuel tank to the line for delivery; injectors for the petrol; injectors for the fuel; a rail receiving the supply of the fuel from the line for deliver to the injectors for the fuel; a pressure and temperature sensor positioned between the fuel tank and the injectors for the fuel; an electronic pressure regulator and heat exchanger with an injector being positioned between the fuel tank and the injectors for the fuel; and an electronic control unit for deviation and regulation of the pressure being operatively associated with the injector of the pressure regulator and heat exchanger and configured to be operatively associated with the electronic control unit of the engine, wherein said electronic control unit for deviation and regulation of the pressure receives from the electronic control unit of the engine electrical signals as a function of injection times, engine r.p.m., and a signal sent by at least one of a lambda probe and a rheostat of the accelerator of said vehicle, and wherein said electronic control unit for control and regulation of the pressure processes said signals and sends signals, at a variable frequency, to the injector of the pressure regulator and heat exchanger so that fuel pressure with which said injectors for the fuel are supplied varies continuously and with a constant progression regulation.
