Title (EN) COOLING SYSTEM
(FR) SYSTÈME DE REFROIDISSEMENT
(JA) 冷却システム
Abstract:
(EN) A cooling system CS according to one aspect of the present invention is provided with: a first cooling circuit C1 which is provided with a first cooling means 54 and in which cooling water can circulate; a second cooling circuit C2 which is provided with a second cooling means 64 and in which cooling water for cooling an engine body 12 can circulate; and an EGR cooler 46 configured to cool an EGR gas. The EGR cooler 46 is provided with: a first EGR cooler 52 installed in the first cooling circuit C1; and a second EGR cooler 62 installed in the second cooling circuit C2. Furthermore, in order to suppress the generation of condensed water due to condensation of moisture in an exhaust gas during the cooling of the EGR cooler 46, the cooling system CS is provided with a valve 80 configured to control the amount of the cooling water that flows from the second cooling circuit C2 to the first cooling circuit C1.
(FR) Un système de refroidissement CS selon un aspect de la présente invention comprend: un premier circuit de refroidissement C1 qui est pourvu d'un premier moyen de refroidissement (54) et dans lequel de l'eau de refroidissement peut circuler; un second circuit de refroidissement C2 qui est pourvu d'un second moyen de refroidissement et dans lequel de l'eau de refroidissement pour refroidir un corps de moteur (12) peut circuler; et un refroidisseur de RGE (46) configuré pour refroidir un gaz de RGE. Le refroidisseur de RGE (46) est pourvu: d'un premier refroidisseur RGE (52) installé dans le premier circuit de refroidissement C1; et d'un second refroidisseur RGE (62) installé dans le second circuit de refroidissement C2. En outre, afin de supprimer la génération d'eau condensée due à la condensation de l'humidité dans un gaz d'échappement pendant le refroidissement du refroidisseur de RGE (46), le système de refroidissement CS est pourvu d'une vanne (80) configurée pour réguler la quantité d'eau de refroidissement qui s'écoule du second circuit de refroidissement C2 vers le premier circuit de refroidissement C1.
(JA) 本発明の一態様に係る冷却システムCSは、冷却水が流通可能な第1冷却手段54を備える第1冷却回路C1と、エンジン本体12を冷却する冷却水が流通可能な第2冷却手段64を備える第2冷却回路C2と、EGRガスを冷却するように構成されたEGRクーラ46とを備える。EGRクーラ46は、第1冷却回路C1に組み込まれた第1EGRクーラ52と、第2冷却回路C2に組み込まれた第2EGRクーラ62とを備える。更に、冷却システムCSは、EGRクーラ46における冷却で排気ガス中の水分の凝縮により凝縮水が生成するのを抑制するべく、第2冷却回路C2から第1冷却回路C1への冷却水の流入量を調節するように構成されたバルブ80を備える。
