要約
(EN)
The amount of injection of emulsion fuel is optimally controlled. An engine (200) has a fuel supply device (300) capable of supplying , as the fuel for a common rail (209), emulsion fuel formed by substantially uniformly mixing, by using a mixer (309), light oil (FL) contained in a main tank (301) and water (WT) contained in a first sub-tank (305). An ECU (100) controls fuel injection. In the process of control of the fuel injection, the ECU (100) calculates the amount of heat generated by water in the fuel by using both the percentage of water content in the fuel and the efficiency of reaction of water. The calculation by the ECU (100) is made according to a preset calculation formula, and the percentage of water content is estimated based on the flow rates of the light oil (FL) and the water (WT) that are detected by flow rate sensors (314, 315). According to the calculated heat generation amount, the ECU (100) corrects a basic fuel injection time (TAU0) previously determined according to operating conditions of a vehicle and calculates an accurate injection time (TAU1) in which the heat generation amount of the water is taken into consideration.

Selon l'invention, la quantité d'injection de combustible en émulsion est commandée de façon optimale. Un moteur (200) comprend un dispositif d'alimentation en combustible (300) qui est capable de fournir, comme combustible pour un rail commun (209), un combustible en émulsion qui est formé par un mélange sensiblement uniforme, effectué en utilisant un mélangeur (309), une huile légère (FL) contenue dans un réservoir principal (301) avec de l'eau (WT) contenue dans un premier réservoir secondaire (305). Une UCE (100) commande l'injection de combustible. Dans le procédé de commande d'injection de combustible, l'UCE (100) calcule la quantité de chaleur générée par l'eau dans le combustible en utilisant à la fois le pourcentage de la teneur en eau dans le combustible et le rendement de la réaction de l'eau. Le calcul de l'UCE (100) est effectué sur la base d'une formule de calcul préétablie, et le pourcentage de la teneur en eau est estimé sur la base des débits de l'huile légère (FL) et de l'eau (WT) qui sont détectés par des capteurs de débit (314, 315). Selon la quantité de génération de chaleur calculée, l'UCE (100) corrige un temps d'injection de combustible de base (TAU0) qui a préalablement été déterminé sur la base des conditions de fonctionnement d'un véhicule et calcule un temps d'injection précis (TAU1) pendant lequel la quantité de génération de chaleur de l'eau est prise en considération.

エマルジョン燃料の噴射量を好適に制御する。コモンレール(209)に対し、燃料として、メインタンク(301)に貯留された軽油(FL)と第1サブタンク(305)に貯留された水(WT)とをミキサ(309)で略均一に混合してなるエマルジョン燃料を供給可能な燃料供給装置(300)を有するエンジン(200)において、ECU(100)は、噴射制御を実行する。噴射制御の実行過程において、ECU(100)は、流量センサ(314、315)により検出される軽油(FL)及び水(WT)の流量に基づいて推定される燃料中の含水比率と、水の反応効率とを使用して、予め設定された演算式に従って燃料中の水の発熱量を算出すると共に、算出された発熱量に応じて、予め車両の運転条件に応じて決定された燃料の基本噴射時間(TAU0)を補正し、水の発熱量を考慮した正確な噴射時間(TAU1)を算出する。
