PURPOSE:To correctly detect the flow rate of the inhaled air by arranging an inhaled air temperature sensor on the upstream side of a throttle valve. CONSTITUTION:An inhaled air temperature sensor 27 is arranged on the upstream side of a throttle valve 7. Each signal of a throttle-valve opening-degree sensor 15, inhaled air pressure sensor 16, inhaled air temperature sensor 27, and a revolution speed sensor 18 is introduced into a controller 10, and fuel injection amount is calculated. Since the temperature and pressure of the inhaled air can be measured at a substantially same place, the amount of the inhaled air can be correctly detected.
