The automobile pressure gauge is an instrument used to test the hydrostatic pressure inside the automobile. The following is an introduction to the automobile pressure gauge:

Type: Common automotive pressure gauges include engine oil pressure gauges, fuel pressure gauges, brake system pressure gauges, tire pressure gauges, and cylinder pressure gauges. Each type of pressure gauge is designed for a different system or component in the car.
Function: The oil pressure gauge is used to monitor the pressure of engine oil; the fuel pressure gauge is used to detect the pressure of the fuel system; the brake system pressure gauge is used to measure the pressure of the braking system; the tire pressure gauge is used to test the tire pressure; cylinder pressure The meter is used to measure the compression pressure of the cylinder to help understand the sealing performance of the cylinder, piston, valve, etc.
Reading method: When reading a car pressure gauge, you need to ensure that the pressure gauge is installed correctly and working properly. Observe the scale and unit of the pressure gauge to understand its range. When reading, your gaze should be perpendicular to the dial to avoid viewing angle errors. At the same time, it is necessary to ensure that the measurement environment is stable and the vehicle status meets the measurement requirements.
Accuracy Requirements: Correctly reading your vehicle's pressure gauge is critical to accurately determining your vehicle's operating condition. Calibrate and maintain the pressure gauge regularly to ensure its accuracy, so as to detect vehicle faults in time, ensure driving safety and extend the service life of the vehicle.

Overall, a car pressure gauge is an indispensable tool in car repair and maintenance.
