Document Type and Number:
Japanese Patent JP3118000
Kind Code:
B2
Abstract:
The pre-mixing chamber (4) is a component of an atomiser (2) for an exhaust gas cleaning unit and is used to mix a pressurised gas (20), e.g. compressed air, with a reducing agent (8), e.g. a urea solution. It is constructed on the carburettor principle. Consequently, the feed (52) for the pressurised gas (20) has a narrowed station (58) and the feed (60) for the reducing agent (8) opens in the region of said narrowed section (58). This ensures that no substances arising from the reducing agent (8) can be deposited in the mixing region. The pre-mixing chamber is intended in particular to a vehicle exhaust gas cleaning unit fitted with a controlled diesel catalyst and for stationary diesel engines up to about 1000 kW (mechanical power).
