Abstract: The invention relates to a self-igniting gasoline internal combustion engine comprising at least one cylinder (1), a cylinder head (2) closing the cylinder (1), a piston (3) mounted in the cylinder (1) in a sliding manner, a combustion chamber (4) which is defined in the cylinder (1) between an upper face (3) of the piston (3) and a lower face (20) of the cylinder head (2), a means (5) for injecting gasoline into the combustion chamber (4), admission valves (7) and exhaust valves (8) which selectively close the combustion chamber (4), and an injection pump (8) for supplying the injector (5) with gasoline under pressure. According to the invention, the air-gasoline mixture is spontaneously ignited and the pressure of the gasoline supplied to the injector exceeds 250 bar.

Abstract: A method and system for exploiting the signals of linear inductive sensors, which system is adaptable for different sensor structures. The system is formed of a linear inductive displacement sensor provided with a primary coil and two identical symmetrical secondary coils which are in series and in antiphase. A mobile core and an alternative voltage source are mounted between the terminals of the primary coil wherein the amplitude of the voltage at the primary coil terminals is greater than the maximum amplitude of the voltage that can be taken at the secondary coil terminals. The method has the steps of forming the sum of the two alternative voltages present at the primary and secondary coils. These voltages are rectified by means of full wave rectifying and deriving the difference between the sum of recitified voltages. A continuous means valve corresponding to the difference is also derived.
