Pre-mixing chamber for an exhaust gas cleaning unit

摘要: The pre-mixing chamber (4) is a component of an atomiser (2) for exhaust gas cleaning unit and used to mix pressurised (20), e.g. compressed air, with reducing agent (8), urea solution. It constructed on the carburettor principle. Consequently, feed (52) (20) has narrowed station (58) (60) (8) opens in region said section (58). This ensures that no substances arising from can be deposited mixing region. intended particular vehicle fitted controlled diesel catalyst stationary engines up about 1000 kW (mechanical power).
