PURPOSE:To ensure a smooth acceleration control, by arranging such that a fuel supply increase for accleration may reach its peak value when an engine cooling water has a lower temperature. CONSTITUTION:A valve opening period of fuel flow regulating means is obtained by adding to and/or multifying a constant and/or factor responsitve to various characteristics indicating an engine operating condition a datum which depends on an engine speed and an absolute pressure in an intake tube. That is, a factor of cooling water temperature increase (KTWT>KTW) in accleration is calculated from a factor of cooling water temperature increase (KTWT) which is to be employed in operations other than acceleration, and then the factor of cooling water temperature increase (KTWT) in acceleration is multiplied by a constant of acceleration fuel increase TACC, TiA so as to ensure that more fuel may be injected than the increase as provided by the above constant TACC, TiA. In this manner, an internal engine can provide improved acceleration characteristics, and thereby ensuring to achieve more smooth acceleration control. |
