| 摘要 |
The invention relates to a method for operating a piston internal combustion engine in which the required fuel quantity for the respective combustion cycle is measured by a motor control (5) according to the load requirement and is directly injected into each individual cylinder (I, II) by means of an injection nozzle (7). After additional injection of the fuel quantity via the injection nozzle, said fuel quantity being measured for the combustion cycle, an additional fuel quantity is injected after completion of the combustion phase when the piston is respectively located in the area of the low dead center position during the expansion stroke thereof. According to the invention, the exhaust exiting the cylinders is guided through at least one mechanical, chemical and/or catalytic operative exhaust treatment device (10, 11) for removing pollutant parts. |
