Power steering refers to assisting the driver in adjusting the direction of the car, reducing the effort required to turn the steering wheel. Power steering systems can be roughly divided into the following three categories: 1. Mechanical hydraulic power steering system. The mechanical hydraulic power steering system generally consists of components such as a hydraulic pump, oil pipes, pressure and flow control valve body, V-belt, and oil reservoir. 2. Electro-hydraulic power steering system. The main components include an oil reservoir, power steering control unit, electric pump, steering gear, power steering sensor, etc., where the power steering control unit and electric pump are integrated into a single structure. 3. Electric power steering system. This system uses the power generated by an electric motor to assist the driver in steering.

I've always been fascinated by car mechanics. Power steering is essentially a device that makes turning the steering wheel easier. Cars in the past didn't have this system, so you had to put a lot of effort into turning the wheel when parking or making low-speed turns. Nowadays, almost all cars are equipped with either hydraulic or electric power steering systems. Simply put, how it works is when you turn the steering wheel, sensors detect the change in force, and the computer activates the motor or oil pump to add some assistance, making it easier for you to handle. Electric power steering has become very popular recently, as it's powered by the battery, responds quickly, and saves fuel. At high speeds, it can automatically adjust the assistance to make steering more stable. This technology has been a great help to drivers since the 1950s, making parking less exhausting and reducing the risk of accidents caused by insufficient strength. In short, with power steering, both the joy of driving and the sense of safety are elevated.

How to Deal with Frost on the Car Windshield?

In winter, frost and ice formation on car windshields are extremely common, mainly caused by the significant temperature difference between the inside and outside of the car. Therefore, opening the car doors for a few minutes before parking at night, allowing the interior temperature to equalize with the outside, can reduce or even prevent the formation of frost and ice on the windshield in the morning, which is difficult to remove. If frost has already formed on the windshield, follow these steps: 1. Turn on the external circulation to heat the glass; 2. Pour a cup of hot water to wipe the frosted area; 3. Cover the windshield with a newspaper after parking at night; 4. Activate the air conditioner's defrost mode; 5. Clean the glass with dishwashing liquid; 6. Remove the interior heat before parking at night.

How Long Is the Warranty Period for the Transmission?

The warranty period for an automotive transmission is generally no less than 40,000 kilometers or two years. Below are detailed explanations regarding the warranty period for automotive transmissions: 1. Currently, our country mandates that manufacturers provide a warranty for the engine of no less than 40,000 kilometers or two years. Most vehicles now offer an engine warranty that meets or exceeds this minimum national requirement. 2. The repair warranty period for household automotive products is no less than 3 years or 60,000 kilometers, whichever comes first; the three-guarantee validity period for household automotive products is no less than 2 years or 50,000 kilometers, whichever comes first. The repair warranty period and three-guarantee validity period for household automotive products are calculated from the date the seller issues the purchase invoice. 3. Within 60 days from the date the seller issues the purchase invoice or within 3,000 kilometers (whichever comes first), if major components of the engine or transmission exhibit quality issues, consumers may opt for a free replacement of the engine or transmission.

What is the normal idle speed for a car?

When the engine is warm, the idle speed is generally between 550-800 RPM; when the engine is cold, the idle speed is usually between 950-1300 RPM. Below are detailed explanations about car idle speed: 1. Car engine idle speed is one of the engine operating conditions. The idle performance of the engine has a significant impact on emissions, fuel consumption, and comfort. The engine speed during idle is called the idle speed, which should not be too high or too low. If it's too high, it will increase fuel consumption; if it's too low, it will cause unstable engine idle speed. 2. The idle speed of a car differs between cold and warm engine states. Generally, for a well-performing engine under warm conditions, the idle speed is between 550-800 RPM. 3. In a cold state, the car needs to allow the engine to quickly enter the normal working environment after starting. Therefore, during a cold start, the engine's computer automatically injects more fuel, burning more fuel than normal idle to rapidly increase the engine's water temperature and quickly bring the engine to a suitable temperature. Hence, the engine idle speed is higher when cold, generally between 950-1300 RPM. Once the engine temperature rises to a certain level, the idle speed will decrease to the normal value. 4. Idle speed is not necessarily better if it's lower or higher. Since the engine often needs to operate in idle conditions, statistics show that about 30% of urban vehicle fuel consumption occurs during idle. Therefore, reducing fuel consumption during idle is crucial, which is also a requirement for idle control. 5. The main measure to reduce idle fuel consumption is to lower the idle speed. Foreign research indicates that reducing the idle speed by 100 RPM is equivalent to gaining an extra mile per gallon of gasoline. This requires that during engine idle conditions, the speed should not deviate too much from the optimal idle speed when subjected to external disturbances.

What are the differences between gasoline engine oil and diesel engine oil?

There are several differences between gasoline engine oil and diesel engine oil: 1. Different fuel economy grades. According to the ACEA European Lubricant Classification Standard, the latest classification consists of three series: A/B series for gasoline and light-duty diesel engine oils; C series for catalyst-compatible engine oils; and E series for heavy-duty diesel engine oils. 2. The compression ratio of diesel engines is more than twice that of gasoline engines, and their main components endure much higher temperatures, pressures, and impacts than gasoline engines, leading to differences in the materials used for some parts. 3. Diesel fuel contains more sulfur than gasoline. This harmful substance forms sulfuric or sulfurous acid during combustion, which, along with high-temperature and high-pressure exhaust gases, enters the oil pan, accelerating oil oxidation and degradation. Therefore, diesel engine oil formulations require more antioxidant additives and stronger alkaline properties. 4. Different oil viscosities. Diesel engines operate under harsher conditions and require stronger oil film strength (on friction surfaces), so diesel engine oil has higher viscosity to ensure proper engine lubrication.

What is the purpose of the clutch?

The clutch is a component used to connect the engine and the transmission. The functions of the car clutch include the following points: 1. Facilitates smooth vehicle starting. During startup, the clutch temporarily separates the engine from the transmission and then gradually engages. Due to the sliding friction between the driving and driven parts of the clutch, the torque transmitted by the clutch can gradually increase from zero, allowing the vehicle's driving force to gradually build up, ensuring a smooth start. 2. Enables convenient gear shifting. During driving, gear changes are often required to adapt to different driving conditions, and the clutch is used during these shifts. 3. Prevents excessive stress on the drivetrain, avoiding damage. During emergency braking, the wheels suddenly decelerate sharply, while the drivetrain connected to the engine maintains its original speed due to rotational inertia. This often generates inertia torque in the drivetrain far greater than the engine torque, which can easily damage drivetrain components. 4. Reduces torsional vibration impact. The output torque of a car engine is usually unstable. During the engine's operating stroke, the inertia of the engine's rotating system can reduce torsional vibration, but the remaining impact still adversely affects the subsequent transmission and driveshaft. The damping springs in the clutch can significantly reduce torsional vibration impact from the engine, extending the lifespan of the transmission gears.

How often should tires rest during long-distance driving?

It is recommended to take a break every 300 kilometers. Here are precautions for long-distance driving: 1. Driving requirements: Maintain a speed below 100km/h and keep engine RPM above 3000. After four consecutive hours of driving, the driver must rest for 20 minutes; Monitor fuel levels and refuel promptly. After 20 continuous hours of operation (calculated at 100km/h), pay attention to the radiator temperature. 2. Inspection: First, check tire pressure to ensure all four tires have equal pressure; Second, inspect tire wear. The small triangle indicator on the tire sidewall can help determine if the tire needs replacement; Perform dynamic balance testing for each tire. In winter, low temperatures make tire rubber harder and more brittle, significantly reducing the friction coefficient. Therefore, tire pressure should not be too high or too low. Prolonged driving with low pressure in extremely cold temperatures accelerates tire aging; Remove debris lodged in tire treads. Avoid using tires that have been repaired more than once, and replace heavily worn tires or those with different brands or tread patterns.
