What Causes Steering Wheel Vibration at 120 km/h?

Should You Turn Off the Engine While Waiting in the Car?

If waiting in the car for less than five minutes, you don't need to turn off the engine; for more than five minutes, it's better to turn it off. Otherwise, besides wasting fuel and increasing engine carbon deposits, sitting in the car for a long time while waiting not only consumes more fuel but also poses safety risks. The impacts of prolonged idling are as follows: Increased Risk of Freezing: In extremely cold winter regions, prolonged engine idling can easily cause the radiator or lower hose to freeze, blocking the coolant from entering the radiator and even leading to abnormal boiling. Increased Cylinder Knocking: During engine idling, due to lower temperature and pressure inside the cylinders, the preparation time for fuel ignition is prolonged. Additionally, the cylinder's sealing performance decreases, making it more prone to knocking sounds, which shortens the engine's lifespan.

How to Match the Remote for Hyundai Verna?

Verna car key replacement costs approximately 500 yuan. If we want to replace a remote key, the 4S shop needs to match the new key with a "code" from the original car. After the matching is completed, the new key can be activated, and the lost key will immediately become invalid. Even if someone finds your old key, they can only open your car door mechanically but cannot start your vehicle. Therefore, the security level of this "code" becomes a major factor in determining the price. Of course, to achieve absolute security, you need to replace all the car locks, which is much more expensive than replacing a single key. According to the survey results, due to the different levels of "codes" and lock cylinders used in different grades of models, the price of replacing all the car locks is more than 2,000 yuan. Although the 4S shop does not require car owners who have lost their keys to replace all the locks, it is more reassuring to replace them completely if conditions permit.

What Do Engine Power, Torque, and Horsepower Mean?

Here are the specific meanings of engine power, torque, and horsepower: Meaning of Power: Power refers to the amount of work done by an object per unit of time, indicating how fast a car can perform work within a certain period. Theoretically, if the amount of work is constant, the shorter the time, the greater the power value. A car with higher power naturally has better engine performance and stronger explosive force. Meaning of Torque: Torque in a car refers to the rotational force output from the crankshaft of the engine. Under the same power conditions, torque and rotational speed are inversely proportional. Torque reflects a car's load capacity and climbing performance, simply put, its grip strength. Low-speed, high-torque vehicles, such as SUVs and pickup trucks, often have torque amplification systems and typically use body-on-frame construction with rear-wheel or four-wheel drive. Meaning of Horsepower: Horsepower generally refers to metric horsepower. The conversion formula between horsepower and power is 1KW = 1.36 horsepower, and 1 horsepower = 0.735KW. Horsepower is directly related to a car's performance. Under a certain vehicle weight, a car with higher horsepower will theoretically have a shorter 0-100 km/h acceleration time.

What Are the Tips for Buying a Car at an Auto Show?

The prices for buying a car at an auto show are generally quite affordable, and there are many tips to consider when purchasing a vehicle at such events. Here are some tips for buying a car at an auto show: Do Your Homework Before Buying: When preparing, identify and note down the flaws and disadvantages of the car, then compare it with its competitors. Show Interest but Stay Calm: Even if you're already interested in the car, don't show it. Make the salesperson feel that if the price isn't right, you'll walk away and choose another car. Don't Be Fooled by Freebies: When negotiating with the salesperson, they often avoid direct price reductions. Instead, they offer seemingly valuable gift packages, creating an illusion of a great deal.

What are the reasons for a car running at high temperature?

Possible causes include engine overheating, cooling fan malfunction, water pump failure, thermostat failure, or poor radiator cooling. Car water temperature reflects the working condition of the cooling system. The engine operates best at an appropriate temperature, where fuel burns more efficiently and reduces gas emissions. During regular use, avoid prolonged continuous operation of the vehicle. Keeping the car in working condition for extended periods can easily lead to overheating, especially in the engine area where temperatures are higher. Effects of prolonged high temperature in cars: 1. High temperature can cause interior cracking; 2. Elevated cabin temperature releases toxic substances; 3. Increased risk of tire blowouts; 4. Reduced air conditioning cooling efficiency; 5. Overheating of the vehicle body; 6. Increased susceptibility to paint damage; 7. Higher risk of brake failure; 8. Greater likelihood of engine malfunctions. Handling methods for car overheating: 1. If encountering overheating while driving, immediately reduce throttle input and engine speed, then drive at low speed to destination or repair shop to check fans, fluid levels, etc.; 2. Since the heater draws heat from the radiator, turning on the heater can provide temporary relief; 3. If the temperature gauge enters the red zone or boiling occurs, immediately pull over safely. If unable to leave the main road, activate hazard lights, set up reflective warning devices, and move all occupants to a safe distance from the vehicle before inspecting.

Should the Brake Be Released Quickly or Slowly in an Automatic Transmission?

In an automatic transmission, the brake should be released quickly to closely follow the throttle and achieve a greater starting speed. Here is some relevant information about automatic transmission vehicles: Definition of Automatic Transmission: An automatic transmission refers to a system that does not require gear shifting while driving, with the advantage of being easier to operate compared to a manual transmission. Gear Positions in Automatic Transmission: Generally, there are six gear positions in an automatic transmission vehicle, listed from top to bottom as: P, R, N, D, S, L. Automatic transmissions include continuously variable transmission (CVT), electronic paddle shifters, and electronic gear lever shifting. There are three types of transmissions available in the market: Manual transmission, automatic transmission, and semi-automatic transmission.
