    摘要： The invention relates to a variable valve type internal combustion engine and a control method for controlling said engine in which operation modes of plural intake valves (7a) and (7b) provided in one cylinder are independently changed according to the drive region of the internal combustion engine (100). In the low air amount region, the intake airflow is controlled only with intake valve (7a) which operates in the low air amount region and the other intake valve (7b) is operated in the medium and high air amount regions.

    摘要： A thermal flow meter corrects flow rate detection errors produced by vaporization of liquid phase components included in a gas to be measured. The thermal flow meter includes a correction circuit 500 that applies respectively different predetermined voltages to heating resistors consisting of first heating resistor Rh1 and second heating resistor Rh2 of a sensor element disposed in the gas to be measured to set a first temperature state and a second temperature state, calculates a first flow rate value Q1 of the gas to be measured in the first temperature state and a second flow rate value Q2 of the gas to be measured in the second temperature state, and calculates a flow rate correction value ΔQ based on a ratio (Q1/Q2) between the first flow rate value and second flow rate value or a fourth-power value (Q1/Q2) 4 of the ratio to correct a flow rate of the gas to be measured.
