摘要： PROBLEM TO BE SOLVED: To provide a controller of an internal combustion engine which can calculate an amount of air passing through a throttle valve more accurately.
SOLUTION: The controller of the internal combustion engine includes an air intake passage, and the throttle valve 18 for regulating a flow rate of the air passing through the air intake passage. Further, this controller includes a throttle valve passing air flow rate calculating means for calculating the flow rate of the air passing through the throttle valve based on at least an atmospheric pressure, an intake tube internal pressure and throttle opening, and controls the internal combustion engine based on the calculated flow rate of the air passing through the throttle valve. Furthermore, this controller includes a temperature detector for detecting a temperature of perimeter of the throttle valve. The throttle valve passing air flow rate calculating means further calculates, in addition to the atmospheric pressure, the intake tube internal pressure and the throttle opening, the throttle valve passing gas flow rate based on the temperature of the perimeter of the throttle valve.
