device for the homogenisation and improve the supply of engines with carburettors.

摘要

Device which adjusts the combustion of engines during their operations in transitional phases, accelerations, decelerations and changes in the transmission ratios by reduction or suppression of the gas flow through the nozzles of the carburettor, and or by admission, downstream of the carburettor of additional air or exhaust gases, crank-case gases or a mixture of these gases. By its mode of action, the device acts during about75% of the running time of the vehicle in city traffic (case of the ECE 15 cycle). The different embodiments of the device are all characterized by the monitoring system (1-6) controlled by the admission pressure of the engine so that the direction, the intensity and the time of action of the power transmitted to the correcting member (7) be permanently depending on the value of the derivate of that admission pressure with respect to time (POWER = F ((dpa k)/dt) The device may be easily set on any vehicle as an economizer or incorporated in modem combustion systems, conventional or electronic.
