ABSTRACT:
A mass air flow sensor device for determining the mass of air flowing therethrough is operatively associated with an engine control module of an internal combustion engine which uses data corresponding to the mass of air flowing to the engine for controlling the operation of the engine for increased efficiency and lower exhaust emissions. The mass air flow sensor device includes a housing having an air flow-through housing comprising an electrically resistant air temperature sensing element at the air inlet end of the housing and an electrically resistant air heating element in the housing downstream of the air temperature sensing element. The resistor of the air temperature sensing element and the resistor of the air heating element are components of a common electrical circuit. The air heating element is operatively responsive to the temperature of the incoming air as sensed by the air temperature sensing element so that the air heating element is heated to a predetermined temperature increment above the temperature of the air as sensed by the air temperature sensing element. The power dissipated in maintaining the air heating element at the predetermined temperature increment is proportional to the mass of the air flow through the housing. The value of the dissipated power is transmitted to the engine control module to be used to control the operation of the engine.
