Abstract: A diesel engine comprises a turbocharger, an intercooler 4, a particulate filtering unit 10 and an EGR cooler 12. EGR ratio of intake air, injection timing of an injection nozzle and excess air ratio lambda to fuel are controlled depending upon engine-operating load. Lean premixed compression ignition is performed at low engine load; low temperature combustion at low excess air ratio with high EGR ratio is performed at medium engine load; and normal EGR combustion is performed at high engine load.

Abstract: An exhaust gas purification device constructed to reduce and purify NOx by having a NOx storage and reduction catalyst (5) installed in the middle of an exhaust gas flow path (2, 4). A fuel reforming catalyst structure (7) or a plasma fuel reforming means (8) for resolving fuel into H2 and CO is installed on the upstream side of the NOx storage and reduction catalyst (5) in the exhaust gas flow path (2, 4). The fuel is dissolved into H2 and CO, NOx on the surface of the NOx storage and reduction catalyst is efficiently reduced into N2 by the H2 and CO. A high NOx reduction rate is always achieved despite varying operating conditions.
