Abstract:
(EN) A port injection valve (16) injects fuel to an intake passage (12). In multiple injection processing, a demanded injection quantity (Qd) of the fuel is divided into a synchronous injection quantity (Qs) and a non-synchronous injection quantity (Qns) in accordance with at least one of: the load (Qd), which is a physical quantity having a correlation with the amount of air (NE, Ga) to be filled; and the temperature (THW) of an internal-combustion engine (10). The fuel is injected through intake non-synchronous injection and intake synchronous injection in this order. In the intake synchronous injection, the fuel is injected synchronously with a valve-open period of an intake valve (18). In the intake non-synchronous injection, the fuel is injected at a timing more advanced than in the intake synchronous injection.
(FR) L'invention concerne une soupape d'injection dans l'orifice (16) injectant du carburant dans un passage d'admission (12). Dans un processus à injections multiples, une quantité d'injection requise (Qd) de carburant est divisée en une quantité d'injection synchrone (Qs) et en une quantité d'injection non synchrone (Qns) en fonction d'au moins l'un des éléments suivants : la charge (Qd), qui est une quantité physique ayant une corrélation avec la quantité d'air (NE, Ga) à apporter ; et la température (THW) d'un moteur à combustion interne (10). Le carburant est injecté, dans l'ordre, par injection non synchrone d'admission et par injection synchrone d'admission. Dans l'injection synchrone d'admission, le carburant est injecté de manière synchrone avec une période d'ouverture de soupape d'une soupape d'admission (18). Dans l'injection non synchrone d'admission, le carburant est injecté à un moment plus avancé que dans l'injection synchrone d'admission.
(JA) ポート噴射弁(16)は、吸気通路(12)に燃料を噴射する。マルチ噴射処理は、充填される空気量(NE,Ga)との相関を有する物理量である負荷(Qd)と、内燃機関(10)の温度(THW)との2つのうちの少なくとも1つに応じて、同期噴射量(Qs)と非同期噴射量(Qns)とに、要求噴射量(Qd)の燃料を分割する。吸気非同期噴射、吸気同期噴射の順に燃料を噴射する。吸気同期噴射は、吸気バルブ(18)の開弁期間に同期して燃料を噴射する。吸気非同期噴射は、吸気同期噴射よりも進角側のタイミングにて燃料を噴射する。
