Abstract: A disclosure describes a carburetion system for an internal combustion motor which operates wih a mixture of vapor fuel and air. The system comprises: a carburetor which is characterized by operating as a continuous injection system, and a removable heat exchanger which is incorporated into the admission system before the exhaust system, in order to heat the admission system. The carburetor is supplied under constant pressure through a pressure regulator which enables to vary the pressure of the fuel depending on the operating conditions and the behavior of the motor in general; moreover, the carburetor is provided with automatic control means to regulate the proportion of the quantities of air which accompany the formation of vapor fuel and the heat exchanger; finally, this system enables to limit the premature expansion of the combustible mixture which is introduced into the combustion chambers.

Abstract: The disclosure describes the improvement to a carburation system for an internal combustion motor which operates with a mixture of motor fuel vapor and air. The system comprises a carburetor, a heat exchanger and an admission block. The main object of the present invention is to decrease in a positive manner the losses of power of the explosion in the motor-cylinder, which are caused by a premature expansion of the air during its passage in the heat exchange compartments. The invention is characterized by the fact that a portion only of the air which is required for the explosion will pass in the heat exchange compartment with the motor fuel which will be transformed into vapor under the effect of heat. The other part of the air will go through the heat exchanger (by an independent air duct) will arrive directly in the system of admission of the motor cylinder.

Abstract: The disclosure describes a carburetion system for internal combustion motor comprising a carburetor, a heat exchanger and an admission block. The carburetor has a carburetion chamber for each motor cylinder and is provided with a motor-fuel reservoir, each chamber having a butterfly valve for controlling the introduction of air. A primary circuit individually feeds each chamber from the reservoir while a secondary circuit, which is independent from the chambers, directly feeds the motor cylinders with an excess of motor fuel which is fed from the reservoir. The heat exchanger, which is connected to the carburetor, comprises an independent heat exchange compartment for each carburetion chamber to which it is connected for enabling the mixture which is produced in the chamber to flow directly into the compartment. The combustion gases of the motor are brought around the compartments for evaporating the motor fuel of the mixture which flows therein.
