Patent

CA 2581794

The invention relates to a method for increasing the torque of a reciprocating piston internal combustion engine, especially a diesel engine (1), which comprises at least one cylinder (20), one turbine (3), one compressor (4), one charge air compressor (11), one first and second storage device (10, 14), one intercooler (5) in an intercooler line (6), one air drier (13), one feed valve (15) and one control device (16). Said method is characterized by the following steps: compressing air from a charge air line (6) or from a second air inlet (31) by means of the charge air compressor (11), storing the air compressed by the charge air compressor (11) in a storage device (10, 14); and blowing, in a clocked manner, blow air (25) which is stored as compressed air in a storage device (10, 14) into the cylinder (20) through an inlet valve (21) of the cylinder (20), thereby increasing the torque of the engine (1). The invention also relates to a device for carrying out said method.

Procédé d'augmentation du couple d'un moteur alternatif à combustion interne, en particulier d'un moteur diesel (1) qui comporte au moins un cylindre (20), une turbine (3), un compresseur (4), un compresseur d'air (11), des premier et second dispositifs de stockage (10, 14), un dispositif de refroidissement (5) de l'air de suralimentation situé dans une conduite (6) d'air de suralimentation, un séchoir d'air (13), une soupape d'admission (15) et un dispositif de commande (16). Ledit procédé comprend la compression de l'air provenant d'une conduite (6) d'air de suralimentation ou d'un deuxième orifice d'entrée d'air (31) par le compresseur d'air (11), le stockage de l'air comprimé par le compresseur d'air (11) dans un dispositif de stockage (10, 14) et l'injection rythmée d'air d'injection (25), stocké dans un dispositif de stockage (10, 14) en tant qu'air comprimé, dans le cylindre (20) par une soupape d'admission (21) du cylindre (20), ce qui permet l'augmentation du couple du moteur (1). La présente invention concerne également un dispositif permettant la mise en oeuvre dudit procédé.
