Title (EN) A WORKING CYCLE FOR A HEAT ENGINE, ESPECIALLY AN INTERNAL COMBUSTION ENGINE, AND AN INTERNAL COMBUSTION ENGINE
(FR) CYCLE DE FONCTIONNEMENT D'UN MOTEUR THERMIQUE, NOTAMMENT D'UN MOTEUR A COMBUSTION INTERNE, ET MOTEUR A COMBUSTION INTERNE
Abstract: front page image
(EN)The present invention relates to a working cycle for a heat engine, especially of the reciprocating piston type, having a gas as working medium, including the steps of isentropic compression of the gas, isochoric addition of heat to the gas, isentropic expansion of the gas, and isochoric return of the gas to its initial condition. The invention is characterized in that the gas, before or during the compression, is divided into two portions, that the gas portions are compressed to different degrees, that heat is added only or mainly to the gas portion compressed to the lowest degree, and that the two gas portions are brought into connection with each other and are expanded together.
(FR)La présente invention concerne un cycle de fonctionnement d'un moteur thermique, notamment du type à piston alternatif, ayant un gaz comme agent opérationnel. Ce cycle de fonctionnement comprend : la compression isentropique du gaz, l'addition isochorique de la chaleur au gaz, l'expansion isentropique du gaz et le retour isochorique du gaz à son état initial. L'invention est caractérisée en ce que le gaz, avant ou pendant la compression, est divisé en deux fractions; en ce que les fractions de gaz sont comprimées à des degrés différents ; en ce que la chaleur est ajoutée seulement ou principalement à la fraction de gaz de plus faible compression, et en ce que les deux fractions de gaz sont réunies et sont détendues ensemble.
