Title (EN) CORRECTING DEVICE FOR THE COMBUSTION OF ENGINES OF VEHICLES DURING TRANSITIONAL PHASES OF OPERATION
(FR) DISPOSITIF CORRECTEUR DE CARBURATION DES MOTEURS DE VEHICULES EN PHASES DE FONCTIONNEMENT TRANSITOIRES
Abstract: front page image
(EN)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.
(FR)Le dispositif selon l"invention corrige la carburation des moteurs au cours de leur fonctionnement en phases transitoires, accelerations, decelerations et changements des rapports de transmission par reduction ou suppression du debit d"essence des gicleurs du carburateur ou/et par admission, en aval du carburateur, d"air additionnel ou de gaz d"echappement, de gaz de carter ou d"un melange de ces gaz. Par son mode d"action, le dispositif agit durant 75% environ du temps de roulage d"un vehicule en circulation urbaine (cas du cylce ECE 15). Les differentes versions du dispositif sont toutes caracterisees par le systeme de commande (1-6) pilote par la pression d"admission du moteur de maniere que le sens, l"intensite et la duree d"action des efforts qu"il transmet a l"organe de correction (7) soient en permanence fonction de la valeur de la derivee de cette pression d"admission par rapport au temps (EFFORT = f (dpa k)/dt. Le dispositif peut etre facilement mis en place sur tout vehicule en service en tant qu""Economiseur" ou incorpore dans les systemes de carburation modernes, conventionnels ou electroniques.
