Abstract

Sistema de arranque en frío de motores diesel de inyección directa rápidos. El sistema está basado en realizar un precalentamiento de toda la carga del aire de admisión de un motor diesel (1) de inyección directa rápido, mediante resistencias eléctricas (7) y/ó (7''), efectuándose ese precalentamiento del aire antes de alcanzar éste la cámara de combustión de los cilindros (2) del motor (1). La resistencia y/o resistencias eléctricas (7) y/ó (7'') se disponen antes del colector de admisión (3) y/o con anterioridad a las válvulas de admisión del motor, de manera que cuando las pérdidas de energía calorífica a través de las paredes del colector sean bajas, bien porque el correspondiente colector de admisión (3) es de un material con baja conductividad térmica o por otras razones, generalmente se dispone una única resistencia eléctrica (7) para el precalentamiento, que se sitúa en la entrada de dicho colector, mientras que si las pérdidas a través de estas paredes son altas, (por ejemplo porqueel colector es de un material con alta conductividad térmica), se disponen una serie de resistencias eléctricas (7''), inmediatamente antes de la entrada a cada uno de los cilindros (2) del motor (1). Cuando un compromiso entre pérdidas de energía permisibles, y costes de la implementación en función del material del colector lo requiera, se puede utilizar de manera combinada las soluciones anteriormente mencionadas.Cold start system of fast direct injection diesel engines. The system is based on preheating the entire intake air load of a fast direct injection diesel engine (1), using electric resistors (7) and / or (7 ''), preheating the air before reach the combustion chamber of the cylinders (2) of the engine (1). The resistance and / or electrical resistors (7) and / or (7 '') are arranged before the intake manifold (3) and / or before the intake valves of the engine, so that when the heat energy losses through the walls of the collector are low, either because the corresponding intake manifold (3) is made of a material with low thermal conductivity or for other reasons, a single electrical resistance (7) is generally provided for preheating, which is located at the entrance of said collector, while if the losses through these walls are high, (for example because the collector is made of a material with high thermal conductivity), a series of electrical resistors (7 '') are arranged, immediately before of the entrance to each of the cylinders (2) of the engine (1). When a compromise between allowable energy losses and implementation costs depending on the material of the collector so requires, the aforementioned solutions can be used in combination.
