PURPOSE:To control the idling speed smoothly, by correcting the injection quantity of fuel on the basis of deflection or vibrational acceleration speed of an engine before and after combustion, independently for each cylinder. CONSTITUTION:Vibrational acceleration speed after injection of fuel is detected by a vibrational acceleration speed sensor 3, and the vibrational acceleration speed (gli) after injection of fuel is put into a control computer 9. Further, deviation between (gli) and the vibrational acceleration speed (ghi) before injection of fuel is detected for each cylinder and it is considered as increment (DELTAgi) of the vibrational acceleration speed. Then, the newest average increment (DELTAg') of the vibrational acceleration speed is renewed, and injection quantity of fuel is controlled through comparison of DELTAgi and DELTAg'. By employing such a method, it is enabled to control the idling speed smoothly. |
