Exhaust-gas purification system for diesel engines

An exhaust-gas purification system for diesel engines, the exhaust-gas purification system comprising:

• a housing having a first end side, a second end side, a first lateral chamber in vicinity of said first end side and a second lateral chamber in vicinity of said second end side, said second lateral chamber having an outer annular space with an inner channel;
• at least one exhaust-gas inlet leading into said housing and at least one exhaust-gas outlet leading out of said housing;
• a reduction catalytic converter disposed in said first lateral chamber of said housing;
• at least one oxidation catalytic converter disposed in said outer annular space of said second lateral chamber of said housing;
• a reducing agent injection device disposed in said housing and directed toward said inner channel of said outer annular space of said second lateral chamber;
• at least one soot particle separator disposed in said inner channel;
• and
• a flow path for the exhaust gas from said at least one exhaust-gas inlet to said at least one exhaust-gas outlet passing successively through said at least one oxidation catalytic converter, said reducing agent injection device, said at least one soot particle separator, and said reduction catalytic converter.
