Control method for lean burn internal combustion engine |
| abstract |
(57) [Summary] [Object] The present invention relates to a control method for a lean-burn internal combustion engine that performs lean-burn operation leaner than stoichio under required operating conditions, and effectively controls NOx purification during lean operation. The purpose is to be able to do. [Structure] The exhaust system of a lean-burn internal combustion engine has a characteristic that the NOx purification efficiency decreases with time when operating in a lean-burn state, but the NOx purification efficiency recovers when switching to a stoichio or rich operating state. NO x NOx in a lean burn operation with a purification member When the NOx purification efficiency of the purification member decreases, it is configured to temporarily switch to the stoichiometric or rich operating state. |
