  • Arrangement for controlling the recirculation of exhaust gas in internal combustion engines
    Patent number: 3978834
    Abstract: An arrangement for controlling the recirculation of exhaust gases within internal combustion engines, includes a recycling system of conduits connecting the engine exhaust manifold to the main inlet manifold of the carburetion system and having a recirculating valve interposed within such circuit. The obturator of the recirculation valve has a truncated-cone configuration of such design that the increase in the variable area of the opening between the stopper or obturator and its seat is a function of the engine speed and load. In recycling the exhaust gases, the invention serves as an antipollution means for the exhaust gases of internal combustion engines.
