Abstract

La presente materia proporciona un motor de combustión interna (101) para un vehículo (100). El motor de combustión interna incluye al menos una culata de cilindro (203). La al menos una culata de cilindro incluye al menos un puerto de entrada (301). Se proporciona una cámara de combustión para recibir la carga de entrada de un dispositivo de suministro de combustible a través de al menos un puerto de entrada. Se proporciona al menos un puerto de escape (304), que es capaz de expulsar los gases quemados de la cámara de combustión a la atmósfera a través de un tubo de escape (200) del vehículo. El al menos un orificio de escape tiene una porción ascendente (310) contigua a la cámara de combustión y una porción descendente (307) contigua a una abertura de entrada (201) del tubo de escape. La porción descendente del puerto de escape tiene una primera área de sección transversal (APT) sustancialmente igual o sustancialmente menor que una segunda área de sección transversal (APE) de la abertura de entrada del tubo de escape.The present subject matter provides an internal combustion engine (101) for a vehicle (100). The internal combustion engine includes at least one cylinder head (203). The at least one cylinder head includes at least one inlet port (301). A combustion chamber is provided to receive the inlet charge from a fuel supply device through at least one inlet port. At least one exhaust port (304) is provided, which is capable of expelling burned gases from the combustion chamber to the atmosphere through an exhaust pipe (200) of the vehicle. The at least one exhaust port has a rising portion (310) contiguous with the combustion chamber and a descending portion (307) contiguous with an intake opening (201) of the exhaust pipe. The downstream portion of the exhaust port has a first cross-sectional area (APT) substantially equal to or substantially less than a second cross-sectional area (APE) of the intake opening of the exhaust pipe.
