Flash point is an indicator of the volatility of oil products. Below are the relevant introductions: 1. Oil products: The lighter the fraction of the oil product, the greater its volatility, and the lower its flash point. Conversely, the heavier the fraction of the oil product, the smaller its volatility, and the higher its flash point. 2. Flash point: Flash point is also an indicator of the fire hazard of petroleum products. The danger level of oil products is classified according to the flash point. Those with a flash point below 45°C are flammable, while those above 45°C are combustible. During the storage and transportation of oil products, it is strictly prohibited to heat the oil to its flash point temperature. For the same viscosity, the higher the flash point, the better.

The specific condition of the tire: In actual use, the decision to replace a tire is primarily based on its specific condition, with the tread pattern being the most intuitive indicator. When the tread depth wears below 1.6 millimeters, the tire needs to be replaced.

Is the Tire Pressure Monitoring System in the Car Accurate?

Is the Tire Pressure Monitoring System in the Car Accurate? The tire pressure monitoring system in the car is accurate and operates in real-time, immediately detecting if a tire is losing air. The automotive tire pressure monitoring system can automatically monitor and alert for issues such as excessively low tire pressure, excessively high tire pressure, rapid air loss, and excessively high tire temperature. Maintaining adequate tire pressure helps prevent tire blowouts, enhances driving safety, reduces additional fuel consumption caused by insufficient tire pressure, and extends the lifespan of the tires. When the tire pressure is too high, it reduces the tire's shock absorption effect, increases the burden on the vehicle's suspension and shock absorption system, and can damage the engine chassis and suspension system. Uneven tire pressure can lead to braking deviation and accelerate wear on the suspension system.
