Abstract
There is provided an intake-air amount detecting system for an internal combustion engine in which a first temperature of an intake air for an internal combustion engine is measured, the intake-air is heated by an electrical heating element, a second temperature of the heated intake-air is measured, an amount of heat generated by the electrical heating element is adjusted to maintain a difference between the second temperature and the first temperature at a fixed value, and the amount of heat generated by the heating element is calculated to determine the amount of the intake-air to the internal combustion engine.
