Title (EN) CONTROL SYSTEM FOR SUPERCHARGED INTERNAL COMBUSTION ENGINE
(FR) SYSTEME DE COMMANDE POUR MOTEUR THERMIQUE SURALIMENTE
Abstract: front page image
(EN)A control system for a supercharged internal combustion engine provided with a main exhaust passage (20) extending through a turbocharger turbine (21) and further through a catalyst (23, 24) to open to the outside air, an exhaust bypass passage (25) bypassing the turbocharger turbine by branching from the main exhaust passage at the upstream side of the turbine and merging with the main exhaust passage before reaching the catalyst at the turbine downstream side, and an exhaust bypass valve (26) provided at the exhaust bypass passage, the control system for a supercharged internal combustion engine controlling the ignition timing in accordance with at least one of the engine warmup state and the catalyst warmup state until warmup of the internal combustion engine and warmup of the catalyst are completed and further controlling the opening degree of the exhaust bypass valve based on the control of the ignition timing, is provided.
(FR)Cette invention concerne un système de commande pour un moteur thermique suralimenté comprenant: une pipe d'échappement principale (20) traversant une turbine de turbocompresseur (21), puis un catalyseur avant de déboucher sur l'extérieur; un passage de gaz d'échappement en dérivation (25) qui contourne la turbine du turbocompresseur en bifurquant de la pipe principale d'échappement en amont de la turbine et qui rejoint la pipe principale avant le catalyseur en aval de la turbine; et une soupape de bypass d'échappement (26) montée dans le passage en dérivation. Ledit système de commande pour moteur thermique suralimenté commande le calage de l'allumage en fonction d'au moins un état de réchauffement du moteur ou du catalyseur jusqu'à ce que le réchauffement du moteur et du catalyseur soient terminés, et règle en outre le degré d'ouverture de la soupape de bypass d'échappement en fonction du calage de l'allumage.
