Uneven wear between left and right brake discs can be attributed to the following reasons: Material Inconsistency: The rate of wear is primarily related to the material of the brake discs and brake pads. Therefore, uneven material composition of the brake pads could be a contributing factor. Force Imbalance: Frequent braking during turns can lead to an imbalance in the forces applied to the left and right wheels, resulting in uneven wear. Additionally, the right brake disc may become deformed. Inconsistent Caliper Retraction: If the brake calipers do not retract uniformly—for example, due to dirt on one side's retraction bolt or significant differences in the length of the left and right brake fluid lines—this can cause uneven wear. Outer Pad Failing to Disengage: The telescopic rods are sealed with rubber sleeves. However, if water enters or lubrication is insufficient, the rods may not move freely, preventing the outer brake pads from disengaging from the brake discs after braking. This leads to additional wear on the pads. Additionally, inconsistent braking times between the left and right brakes can contribute to uneven wear.

Is It Better to Store a Car in a Cold Storage in Winter Than Outside?

Storing a car in a cold storage in winter is better than leaving it outside. It ensures the car won't freeze. Reasons for parking a car in cold storage: Even in a cold storage, the temperature inside is much higher than outdoors. Keeping the car in cold storage prevents frost from forming on the windows in the morning. If left outside, the temperature inside the car is higher than outside, causing frost to form on the windows. The same applies to the engine—higher indoor temperatures are beneficial for the engine. Solutions for a frozen car: Parking a car outside overnight makes it unavoidable for the doors to freeze. Before driving the next day, it's best to prepare a bottle of warm water and pour it over the frozen door seams. After opening the door, dry it immediately to prevent refreezing. Before parking, lift the windshield wipers, being careful not to force them. If it's windy, also prevent the wind from blowing the wipers down, as they might damage the windshield.

What is the torque range of a torque wrench?

The minimum torque range of a torque wrench is 5N.m, and the maximum is 25N.m. Precautions for hydraulic torque wrenches: The torque of a hydraulic torque wrench does not start from 0; it is also determined by the hydraulic wrench pump. Because the hydraulic wrench pump is a two-stage or three-stage pump, during low-pressure and high-flow conditions, whether it's a gear pump or a plunger pump, there is significant overflow, resulting in unstable pressure and unstable torque output from the wrench. Precise torque measurement starts from the second stage, where the flow rate is much smaller than the low-pressure flow, with no overflow, ensuring stability and allowing for precise torque control. Precautions for using torque wrenches: Do not use a preset torque wrench to remove bolts or nuts. It is strictly prohibited to add an extension sleeve to the end of the torque wrench to increase the leverage, as this may damage the wrench. Adjust the required torque as needed and ensure the adjustment mechanism is in the locked position before use.

Engine Water Temperature?

Engine water temperature may be high due to the following reasons: Cooling system: High engine water temperature may be caused by failure to clean the cooling system as required, leading to excessive scale buildup or debris clogging the radiator core tubes, preventing the coolant from being cooled. If the antifreeze continuously circulates in a small loop, it will not pass through the radiator for cooling, resulting in excessively high antifreeze temperature. Fan belt: High engine water temperature may be caused by damage to the fan belt or slippage of the fan belt, which reduces the rotation speed of the water pump shaft, leading to insufficient water pumping. Alternatively, deformed fan blades may reduce air supply, thereby decreasing the air cooling effect.

How many kilometers can a Tianneng battery with 5 blocks of 60V run?

Tianneng battery with 5 blocks of 60V can run 50 kilometers. Notes on range: The range of an electric vehicle is not only related to the vehicle itself but also to the driver's driving habits and road conditions. Electric vehicles are a relatively common mode of transportation, and their structure is quite simple. Battery maintenance notes: The battery is used to store electrical energy and can also power all electronic devices on the electric vehicle. Without the battery, the electric vehicle cannot operate normally. The battery is a consumable part; as the number of charge and discharge cycles increases, the battery's performance will degrade, so it needs to be replaced regularly. During charging or discharging, ions in the battery move in the electrolyte, and some ions react chemically with the electrolyte as they move.

What does ECON mean in car air conditioning?

The ECON in car air conditioning is actually a mode of the air conditioning system, which only takes effect when the air conditioning's cooling function is turned on. The air conditioning compressor is driven by the engine and can consume up to 20% of the engine's power. When the ECON mode is activated, the vehicle reduces the power consumption of the air conditioning while maintaining its cooling effect, thereby saving fuel. The method to turn on the air conditioning's economy mode is very simple. The owner just needs to press the "Econ" button after turning on the air conditioning. When the light on the button is on, the cooling system of the air conditioning is turned off, and only natural wind or warm air is provided. The introduction to the ECON mode of car air conditioning is as follows: Usually, the car air conditioning has an A/C symbol to indicate whether the air conditioning is turned on or off, while ECON only takes effect when the cooling function is turned on, representing the economy mode of the air conditioning. In this state, the compressor also works. Compared to the normal mode, the control point of the compressor is increased, and the compressor does not continuously engage during operation. The start and stop points of the compressor are controlled by the evaporation temperature. In normal mode, the start and stop points of the compressor are 2~4°C. In ECON mode, the start and stop points of the compressor are 8~10°C. The lower the temperature, the longer the working time and the greater the workload of the compressor. After turning on the ECON mode, it saves the engine's power output and fuel. The functions of car air conditioning: Achieve cooling effect through the continuous cycle of refrigerant; Remove dust, odors, smoke, and toxic gases from the car's air to make the air inside the car fresh, and humidify the air inside the car to increase the relative humidity of the air inside the car; Use the engine coolant, waste heat, or heat generated by a burner as a heat source for heating, which is heated by the heater and sent into the car's air or outside air by the blower to increase the temperature of the air outlet for heating purposes; Draw in fresh air from outside for ventilation and air exchange, which also plays a good role in preventing window fogging. Precautions for using air conditioning in the car: Do not set the air conditioning temperature too low. A large temperature difference between the inside and outside of the car can easily cause the driver to catch a cold, and too low a temperature may also increase the risk of arthritis for passengers in the car. Control the direction of the air outlet. Based on the principle that cold air sinks and hot air rises, when controlling the air outlet of the air conditioning, you can follow the rule of directing the air outlet upward when cooling and downward when heating. Do not turn on the air conditioning immediately after the car has been exposed to the sun. After the car has been exposed to the sun, the temperature inside the car will be very high. First open the windows for ventilation, and then turn on the air conditioning after the hot air has been discharged.
