Water Separation Systems

In order to comply with demanding emissions limits, modern diesel engines typically employ common rail injection systems. These are extremely sensitive to solid particles and diesel fuel containing unsolved water. Since world engines are also used in countries with poor fuel quality and varying shares of biofuel, it is necessary to enable optimal separation of contaminants and water even under these conditions. For this purpose, MAHLE has developed a solution with the active prefilter module that achieves a separation level of up to 98 percent in new condition.
