Title
(EN) ADAPTIVE MIXED-MODE COMBUSTION METHODS AND ENGINES USING THE SAME
(FR) PROCÉDÉS DE COMBUSTION EN MODE MIXTE ADAPTATIF ET MOTEURS UTILISANT CE PROCÉDÉ
Abstract
(EN)
A mixed- mode combustion method, which is mainly for internal combustion engines, either compression ignition or spark ignition, or mixed-mode engines using both compression ignition and spark ignition. The said combustion method utilizes a variable orifice fuel injector or at least two injectors per cylinder wherein it has means to produce variable spray patterns with smaller spray angle jets for earlier injection(s), and larger spray angle jets for main injection(s) around engine top dead center, respectively, in the same engine power cycle, wherein it has adaptive means to distribute fuel into combustion chamber space based on engine loads and speeds, to effectively reduce emissions and fuel consumptions. A combustion engine using the said combustion method is also provided.

L'invention porte sur un procédé de combustion en mode mixte qui est principalement prévu pour des moteurs à combustion interne, soit à allumage par compression, soit à allumage par étincelle, ou des moteurs à mode mixte qui utilisent l'allumage par compression et l'allumage par étincelle. Ledit procédé de combustion utilise un injecteur de carburant à orifice variable ou au moins deux injecteurs par cylindre, ayant des moyens pour produire des formes de pulvérisation variables comportant des jets à angle de pulvérisation plus petit pour l'injection ou les injections précoces et des jets à angle de pulvérisation plus large pour l'injection principale ou les injections principales à proximité du point mort haut du moteur respectivement, dans le même cycle de travail du moteur, et a des moyens adaptatifs pour répartir le carburant dans l'espace de la chambre de combustion en se basant sur des charges et des vitesses de moteur afin de réduire efficacement les émissions et les consommations de carburant. L'invention porte aussi sur un moteur à combustion qui utilise ledit procédé de combustion.
