Which is More Important: Horsepower or Displacement?

Both displacement and horsepower are important, but neither should be excessively large—what suits the vehicle is most crucial. This balance ensures both power and fuel efficiency. Below is a partial introduction to horsepower and displacement: 1. Overview: Engine horsepower refers to the engine's output capability, i.e., its power output. Power output is the most critical parameter for measuring vehicle performance and engine capability. Engine displacement is the total volume of all cylinders' working capacity, calculated as the product of single-cylinder displacement (Vh) and the number of cylinders (I). The working volume of a cylinder refers to the gas volume swept by the piston from top dead center to bottom dead center, determined by the cylinder bore and piston stroke. 2. Influencing Factors: Horsepower affects a car's top speed—the higher the horsepower, the higher the potential top speed. However, modern technologies like turbocharging allow smaller-displacement engines to produce higher horsepower. Generally, engine displacement and horsepower are proportional; examining a car's cylinder count and displacement can give a rough idea of its horsepower potential—the larger the displacement, the greater the horsepower. With advancements in automotive technology, the engine with the largest displacement doesn't always produce the highest horsepower, as new technologies play a fundamental role.

How to Deal with Severe Steering Wheel Noise?

Severe steering wheel noise requires checking if the power steering fluid is low. Adding some lubricating oil can help improve the situation. Alternatively, it could be due to hardened or aged rubber bushings in the suspension stabilizer bar links or internal component wear. If you cannot handle it yourself, you should take the car to a 4S shop for inspection as soon as possible. Below are common steering wheel issues: 1. Steering wheel lock: When the car steering wheel cannot be turned and the key won’t twist, the driver should gently turn the key with the right hand while lightly rotating the steering wheel with the left hand to unlock it. 2. Scratched steering wheel: During repair, first remove impurities and rust. Apply paint in thin layers—small amounts, multiple layers, carefully coating one layer at a time. Wait for it to dry before applying the next layer until it matches the surrounding paint. After repair, wait a day for the paint to harden before washing or repainting. 3. Steering wheel vibration: When driving at speeds between 80 km/h and 90 km/h, the steering wheel may vibrate, but it returns to normal when exceeding 90 km/h. This is usually caused by tire deformation or issues in the vehicle’s drivetrain. Check the front wheel alignment angles and toe-in to ensure they meet specifications; adjust if necessary. Lift the front axle and spin the wheels to check for static imbalance or excessive tire deformation. Replace the tire if it is deformed.

Can a Car Still Run If It Runs Out of Engine Oil?

If a car runs out of engine oil, it cannot continue to operate. Running out of oil means the engine's lubrication system fails, and continuing to drive under such conditions can cause severe damage to the engine. Engine oil serves the functions of lubrication, cleaning, and cooling. If the engine leaks oil, it will lead to excessive wear, first affecting the car's power output. Secondly, as the oil level drops, the engine's cooling efficiency decreases, internal components experience poor lubrication, and sludge buildup becomes severe. Under such conditions, the engine will suffer significant wear, affecting its stable operation and reducing its lifespan. If an engine oil leak is detected, the issue should be resolved before driving. If the leak is noticed while driving, the vehicle must be stopped immediately, and a professional should be contacted—either a 4S shop or an auto repair service—for assistance. Alternatively, a tow truck can be called to transport the vehicle to a repair shop or 4S shop. Causes of oil leaks: Engine oil leaks may occur due to poor sealing in components such as the valve cover gasket, oil cooler, oil filter, distributor housing mounting hole, rocker arm cover, camshaft rear seal cover, or engine mounting plate deformation. Damage to the front and rear crankshaft seals or oil pan gasket can also lead to engine oil leaks. Improper installation or damage to the timing gear cover gasket, as well as loose screws, may result in oil leakage.

Should ESP be kept on or off normally?

Under normal road conditions or during regular driving, ordinary car owners should not easily turn off this system. Below is relevant information about ESP: 1. Information analysis: ESP analyzes vehicle driving state information transmitted from various sensors and then sends correction instructions to ABS, EBD, etc., to help the vehicle maintain dynamic balance. ESP can keep the vehicle in optimal stability under various conditions, with more noticeable effects in cases of oversteering or understeering. 2. Safety: ESP is a very important function in active vehicle safety and may silently assist in emergency situations. However, car owners should not blindly assume that ESP can make the car go faster or provide better handling.

Full Synthetic or Semi-Synthetic Engine Oil: Which One to Use?

Car maintenance is better with full synthetic engine oil. Full synthetic engine oil outperforms semi-synthetic oil in terms of lubricity, protection, durability, and low-temperature fluidity. Semi-synthetic engine oil: It is a lubricant formulated from semi-synthetic base oil, specifically international Group III base oil. It is a product refined from mineral oil through hydrofracking technology, consisting of a mixture of mineral oil and synthetic oil in a 4:6 ratio. The purity of semi-synthetic oil is very close to that of full synthetic oil, but its cost is slightly higher than mineral oil. It serves as an ideal transitional product from mineral oil to synthetic oil. Full synthetic engine oil: To achieve superior oil performance, various oils are chemically synthesized, resulting in chemically synthesized engine oil, commonly referred to as synthetic oil. Full synthetic engine oil offers the following advantages over semi-synthetic oil: Better high and low-temperature performance: Full synthetic oil operates effectively over a wider temperature range and has a longer service life. It can achieve the required performance with lower viscosity, whereas semi-synthetic oil requires a relatively higher viscosity to meet the same requirements. Longer oil change intervals: Engine oil blended with synthetic oil has stronger oxidation resistance, significantly extending the oil change interval. Although the initial investment in oil is higher, it reduces the frequency of oil and filter changes. Better suited for harsher driving conditions: Synthetic oil is more adaptable to higher-load engines, offering superior resistance to high temperatures and shear forces. Even under high-speed engine operation, the oil maintains its viscosity, providing more comprehensive engine protection. Synthetic oil is of higher quality and contributes to better fuel efficiency.
