Abstract

Se divulga un método para el control de superdetonaciones de un motor sobrealimentado de gasolina de inyección directa, que es capaz de controlar las superdetonaciones de manera eficaz. El método de control comprende: identificar cilindros en los que se producen superdetonaciones debido al pre-encendido del gas mezclado desencadenado por la combustión espontánea del aceite de lubricación que entra en los cilindros, e identificar los mismos como cilindros de superdetonación; sacando la última inyección de aceite de cilindros de superdetonación de la carrera de compresión, y permitiendo que el ángulo del cigüeñal cuando se forma el gas mezclado para la combustión no esté por delante del ángulo del cigüeñal correspondiente al pre-encendido controlando el momento de la última inyección de aceite. El método de control en la presente invención es relativamente simple; siempre y cuando el momento de inyección de aceite en los cilindros de superdetonación individuales se pueda controlar, la seguridad de funcionamiento es relativamente alta; y el número de cilindros de superdetonación identificados puede ser uno o más de uno. Los experimentos muestran que el método de control mencionado anteriormente es capaz de controlar las superdetonaciones de manera eficaz.A method for controlling super knock of a supercharged direct injection gasoline engine is disclosed, which is capable of controlling super knock effectively. The control method comprises: identifying cylinders in which super knock occurs due to pre-ignition of the mixed gas triggered by spontaneous combustion of the lubricating oil entering the cylinders, and identifying them as super knock cylinders; removing the last injection of oil from super-knock cylinders from the compression stroke, and allowing the crank angle when forming the mixed gas for combustion to not be ahead of the crankshaft angle corresponding to pre-ignition by controlling the timing of the last oil injection. The control method in the present invention is relatively simple; As long as the timing of oil injection into the individual super-knock cylinders can be controlled, the operational safety is relatively high; and the number of identified super-knock cylinders may be one or more than one. Experiments show that the above-mentioned control method is able to control super-detonations effectively.
