摘要： To realize a control apparatus for an internal combustion engine having a heating resistor type air flow rate measuring apparatus which can effectively remove salinity adhered to the heating resistor. Salt adheres not only to the heating portion of a heating resistor but also to lead members and supporting members. When a certain time period is passed after the current supply to the heating resistor is stopped, the salt adhered thereto absorbs moisture in the air by deliquescence, and becomes salt water near the heating resistor and the support members etc. Then, suction air flows through an auxiliary air passage by the cranking of the engine to disperse the salt water adhered not only to the support member parts but also to the heating resistor. Thus, even if the heating resistor is supplied with current after the dissipation, salt components do not remain on the heating resistor.

摘要： In a thermal type flow rate measurement apparatus comprising a sub-passage having a detour passage and a hole just before a flow rate measuring part, for preventing its output value from falling onto a negative side when the flow rate is abruptly changed, a slit is formed downstream of a flow rate detecting element located after the detour passage. The slit hole may be arranged between the flow rate detecting element and the outlet port part, and may be opened between a wall surface side and a recess part. Thereby, it is possible to prevent the output value from falling in the negative side upon rise-up thereof.

摘要： A thermal type gas flow measuring instrument measures gas flow with high precision by accurately correcting changes in radiation heat characteristics of a heating resistor due to contamination. The instrument comprises a second heating resistor 30 whose resistance value, which changes if contaminated, is calculated by measuring the terminal voltage thereof by calculating means 32, and the calculated value is compared with a temperature detected by a temperature detecting element 31. Based on the result of comparison, the level of contamination of the second heating resistor 30 is determined. The second heating resistor 30 and the first heating resistor 3 are disposed in similar environments such that their levels of contamination can be considered equal. Based on the level of contamination calculated from the result of comparison, a correction value is calculated and the output of the first heating resistor 3 is corrected in accordance with the correction value.

摘要： A thermal type air flow measuring instrument is mounted to a main passage forming an intake air passage of an internal combustion engine and is provided. with an auxiliary passage which includes a heating resistor and a temperature sensing resistor therein and an electronic circuit which is electrically connected to the heating resistor and the temperature sensing resistor. The auxiliary passage is a passage including at least one bent portion composed of a first path substantially parallel to the main passage and a second path having a path different in flow direction from the first path. A member forming the auxiliary passage is fixed in a united form to only a case member for interiorly protecting the electronic circuit, and the case member is fixed to the outer wall surface of the intake air passage. The auxiliary passage structure capable of being handled as a single module united to the case member is effective to the mass production of an air flow control system and the reduction in cost thereof since the structure can be mounted to different kinds of internal combustion engines.
