DEVICE FOR MONITORING TECHNICAL CONDITION OF AIR SUPPLY SYSTEM OF GASOLINE ENGINE OF CAR Russian patent published in 2024 - IPC F02D41/22 G01M15/09 G01M3/16 

FIELD: automotive industry.

SUBSTANCE: invention can be used in devices for monitoring the technical condition of components and assemblies of cars. A device for monitoring the technical condition of the air supply system of a gasoline engine of a car contains plastic composite housing (1), which houses electronic digital control module (2) and wireless data transmission module (3). Electronic digital control module (2) is connected to air pressure sensor (17) via input/output terminal (4), sensor power lines (5), information reading lines (6), output terminal (15) and connector (16) of sensor (17). Wireless data transmission module (3) is connected to electronic digital control module (2) via terminal (7) for inputting wired communication lines and information transmission lines (8). On plastic composite case (1) there is button (9) to turn the device on/off, terminal (12) for connecting power from a battery with a rated voltage of 12 to 24 volts, and output terminal (15). Device on/off button (9) is configured to supply voltage via anode constant signal input line (10) and anode controlled output line (11). Terminal (12) for connecting power from the battery is configured to supply voltage to electronic digital control module (2) via anode power wire connection line (13) and cathode power wire connection line (14). Output terminal (15) is connected by sensor power lines (5) and data reading lines (6) with air pressure sensor (17). Wireless data transmission module (3) is connected to the information display device.

EFFECT: improved accuracy of determining the presence of malfunctions, which include damage and leaks in the air supply system of a gasoline engine of a car in real time.
