Thermal-type airflow meter, intake air system for an internal combustion engine, and control system for the same |
摘要 |
The thermal-type airflow meter comprises airflow meter body 86 and measuring part 87. Both of the frame 31 of the housing 3 accommodating therein the electronic circuit 6 and the subpassage member 4 having the heating resistor 1 etc. positioned within a subpassage of air are arranged on the metallic base 5. Further, the frame 31, the subpassage member 4, the metallic base 5 and the cover 9 are adhered to respectively different member more than one. The connector 32 of the housing 3, the frame 31 and the subpassage member 4 are formed in a flat shape to form the measuring module 87. The measuring module 87 is inserted through the insertion hole 83 to locate the heating resistor 1 within the main air passage 81, and the fixing flange 36 of the housing 3 is fixedly attached to the airflow meter body 86.
