A soot filter system, comprising:
- a soot filter regeneratable by passage of hot air therethrough to burn off collected soot particles and attached to a motor vehicle having a diesel engine producing an exhaust gas containing said soot particles;
- means forming a first inlet connected to said soot filter and receiving said exhaust gas from said diesel engine;
- means forming a second inlet connected to said soot filter;
- and
- an external mobile hot gas generator separate from said motor vehicle and detachably connectable to said second inlet while said soot filter remains attached to said motor vehicle for passing hot air through said soot filter to burn off accumulated soot particles and regenerate said soot filter, the means forming said first and second inlets being constructed and arranged to close off said first inlet from said diesel engine while said hot air is passed through said soot filter from said external mobile hot gas generator.
