  "textContent": "A control unit (7) calculates a quantity of air that is taken into an engine (2) from an output current from an air flow meter (14) that is located downstream from a throttle valve (12). The control unit (7) then determines the quantity of fuel to be injected for this quantity of air. The control unit (7) determines a rise in the air intake as being when the quantity of air is on an increasing trend and has exceeded a predetermined threshold value. In contrast, the control unit (7) determines a fall in the air intake as being when the quantity of air is on a decreasing trend and has exceeded a predetermined threshold value. An injection of fuel starts from a rise in the air intake and is ended at an earlier timing than the end of the air intake.",
