What is the Principle of an Automotive Transmission?

The principle of an automotive transmission is to use gear sets with different numbers of teeth to achieve changes in rotational speed and torque. Here is an introduction to the transmission: 1. Functions of the transmission: Changing the gear ratio to meet the traction needs under different driving conditions, allowing the engine to operate under favorable conditions; enabling the vehicle to move in reverse; interrupting power transmission when the engine is idling, during gear shifts, or when the vehicle is parked, thus cutting off power to the drive wheels; engaging neutral gear, which stops power output from the transmission when the clutch is engaged. 2. Maintenance methods for the transmission: Regularly check the fluid level; avoid skipping gears when upshifting; do not force the transmission into neutral; do not shorten the warm-up idling time; and avoid gear grinding when shifting.

How to Turn on the Heater in Changan 55?

Changan 55's method to turn on the heater: The air conditioning switch is the knob-style control button on the dashboard. One side is marked in blue for cold air, and the other side is marked in red for warm air. To turn on the heater, rotate the knob toward the red position. The larger the red pattern, the warmer the air, and you can adjust it according to your needs. The heating principle of the car air conditioner: When heating, the high-temperature coolant from the engine flows through the heater core. At this time, the air blown by the blower also passes through the heater core, allowing the car air conditioner vents to blow warm air. The heater core acts as a heat exchanger. Most car air conditioners use R134a refrigerant, which needs to be replaced regularly. If the refrigerant is not replaced for a long time, the car air conditioner's cooling effect will deteriorate, and the cooling speed will slow down.
