It is best to keep the car interior temperature between 18-25 degrees Celsius. Generally, a temperature difference of within 10 degrees between the inside and outside of the car is appropriate. The most comfortable temperature for the human body is 20-25 degrees. If it exceeds 28 degrees, people will feel hot, and if it is below 14 degrees, people will feel cold. How to activate the air conditioning heating: In winter, if you need to use the car air conditioning, you should start the car first and wait a few minutes. The engine will begin to warm up. When the engine temperature gauge reaches the middle position, turn on the air conditioning heating. However, you should also set the air circulation mode to external circulation to expel the cold air from the car. After 5 minutes, you can switch back to internal circulation and start driving. When the car is just started, the engine coolant temperature has not yet risen. Turning on the air conditioning heating immediately will dissipate the already limited heat. Each car's engine has its optimal working state. If the temperature is too high or too low, it will not only damage the engine but also increase fuel consumption. How car air conditioning works: Car air conditioning does not have a heating function. The warm air in car air conditioning comes from the engine's heat dissipation. Therefore, those who need to use the heater in winter do not have to worry about additional fuel consumption like in summer when using the air conditioning for cooling. Just pay attention to the timing of turning on the heater. Also, please note that the term 'air conditioning heating' mentioned in this article actually refers to turning on the heater.

What Happens When the Exhaust Check Valve Fails?

Problems that may occur when the exhaust check valve fails include: 1. The vehicle may burn engine oil; 2. The engine may experience unstable idling or even stall; 3. The car's exhaust may appear darker in color and emit a strong odor. Below is an introduction to the exhaust check valve: The exhaust check valve serves to separate oil vapor and can also redirect a portion of the exhaust gases back into the combustion chamber for reburning. When the engine is running, the high temperatures can cause engine oil to vaporize. This vaporized oil, mixed with some exhaust gases, reaches the exhaust check valve. The valve is responsible for separating the oil vapor and then redirecting the remaining exhaust gases back into the combustion chamber for secondary combustion.

What are the common types of oil pumps in automatic transmissions?

There are three common types of oil pumps in automatic transmissions: internal gear pumps, rotor pumps, and vane pumps. Among these, the first two types are referred to as fixed-displacement pumps because they discharge the same amount of oil per revolution. Below are the specific details: 1. The drawback of these two types of pumps is that as the pump speed increases, the required driving energy also rises, even when the automatic transmission does not require excessive oil supply. 2. Vane pumps are further divided into fixed-displacement vane pumps and variable-displacement vane pumps. Since the hydraulic system of an automatic transmission is a low-pressure system, with working oil pressure typically not exceeding 2MPa, the most widely used type remains the internal gear pump.

What are the techniques for accelerating from 0-100 in an automatic transmission car?

Mastering the techniques for accelerating from 0-100 in an automatic transmission car requires proficient driving skills. Here are the detailed techniques: 1. Double-tap the accelerator: Pressing the accelerator twice can increase the car's speed. After the first press and release, the transmission may oscillate, and then pressing the accelerator a second time will significantly boost speed without causing the engine to roar. 2. Avoid flooring the accelerator: Pressing the accelerator all the way down at once puts the engine under high load. Instead, press the accelerator once, release it, and then press it again for smoother and faster acceleration. 3. Shift gears properly: Appropriate gear shifting can enhance the car's speed.
