What do h and t mean?
2 Answers
h indicates that the maximum speed cannot exceed 210, while t indicates that the maximum speed cannot exceed 190 kilometers per hour. Service life of car tires: The service life of tires is about 5 years, with the specific duration related to driving habits, temperature, and environment. Tires are rubber products and generally last 5 to 6 years. Over time, they will age, develop cracks, and become prone to blowouts. Functions of car tires: They support the entire weight of the vehicle, bear the load of the car, and transmit forces and moments in other directions. They also transfer traction and braking torque, ensuring good adhesion between the wheels and the road surface to improve the car's power, braking, and off-road capabilities. Together with the car suspension, they help to mitigate the impact during driving and dampen the resulting vibrations.
I remember the common H and T indicators on the car dashboard. H stands for the engine coolant temperature overheating warning. Sometimes, if the radiator cooling fan fails, the coolant is insufficient, or the thermostat gets stuck, and the needle rushes to the red zone H position, you should stop the car immediately for inspection. Continuing to drive may cause cylinder scuffing. T represents the monitoring of the engine intake air temperature sensor. For example, when the outside temperature is 30 degrees, the intake pipe temperature of a turbocharged car can reach 60 degrees. An abnormal rise in this value can affect the air-fuel ratio, leading to a sharp increase in fuel consumption or a decrease in power. Experienced drivers know how important it is to monitor these two parameters, and modified cars especially need to install a turbo gauge to keep an eye on temperature fluctuations.
