Control device for internal combustion engine |
| abstract |
(57) [Abstract] [Purpose] To detect the combustion roughness without using an expensive sensor and to appropriately control the exhaust gas recirculation amount. An ignition voltage is detected by an ignition voltage sensor 17, and a period TP in which the ignition voltage value V exceeds a comparison level VCOMP is measured (FIG. 4). The relationship between the combustion roughness R and the exhaust gas recirculation amount EGRM (FIG. 6A) and the period T From the relationship between P and the exhaust gas recirculation amount EGRM ((b) in the figure), the relationship between the combustion roughness R and the period TP is obtained ((c) in the figure), and the combustion roughness R is calculated according to the period TP. To do. The exhaust gas recirculation amount EGRM is controlled according to the detected combustion roughness. |
