What Causes Front Wheel Abnormal Noises in Cars?

There are five common causes for front wheel abnormal noises in cars: nails punctured in tires causing friction sounds with the road surface; brake pads reaching their service limit, resulting in metal layer friction noises; shock absorber hydraulic oil leakage leading to loss of damping effect; loose lower control arm ball joints; and loose chassis bushings or bolts. Below are detailed explanations: Nails punctured in front tires: During driving, the friction sound between metal nails and the road surface may occur. Park the vehicle in a safe location, check if all four tires have sufficient pressure, and if so, proceed to a nearby repair shop for thorough inspection. Brake pads reaching service limit: Friction with the internal metal layer occurs. Brake pads, which closely contact the brake discs, are internally made of ceramic material. Once the ceramic wears out, the external metal layer begins to wear, producing abnormal noises. Shock absorber oil leakage: Shock absorbers contain sealed hydraulic oil to reduce significant vibrations when driving over bumpy roads, enhancing passenger comfort. If the oil seal is damaged, most hydraulic oil will leak out, causing loss of damping effect and generating abnormal noises during driving. Loose lower control arm ball joints: Ball joints are lubricated with grease. If the dust cover sealing the grease is damaged, the grease may become contaminated with water or dirt, losing its lubricating effect and causing ball joint looseness, which can also lead to front wheel noises. Loose chassis bushings or bolts: Chassis components are connected with soft materials like bushings to effectively isolate chassis impacts on the cabin and improve driving comfort. If chassis bushings fall off or are damaged, abnormal noises will inevitably occur. Loose bolts can also cause incorrect clearances between chassis components, especially leading to minor lateral displacements during driving.

Is the Suzuki Fengyu equipped with a Japanese engine?

The engine of the Suzuki Fengyu is not Japanese; it is domestically produced. The Suzuki Fengyu uses two types of engines, with model numbers CAS16 and K14C. The CAS16 engine has a maximum horsepower of 122 HP, a maximum power output of 90 kW, a maximum power speed of 6000 rpm, and a peak torque of 420 N.m. The K14C engine has a maximum horsepower of 140 HP, a maximum power output of 103 kW, a maximum power speed of 5500 rpm, and a peak torque of 220 N.m. For daily maintenance of the Suzuki Fengyu's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, choose CB_CD grade diesel engine oil according to mechanical load, with the selection standard being no lower than the manufacturer's specified requirements. Regularly change the engine oil and oil filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, the performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts of sludge remain suspended in the oil, while larger amounts precipitate, clogging the filter and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

What is the Principle of Hybrid Power?

The following is an introduction to the principle of hybrid power and related information about hybrid vehicles: 1. Principle of Hybrid Power: The principle of hybrid power involves the combination of a traditional gasoline engine and an electric motor to output power. The engine's operation is used to charge the battery, and the power generated by the car's electric motor and engine is continuously switched and converted. 2. Hybrid Power: Based on the degree of dependence on electric energy, hybrid power can be divided into Mild Hybrid (also known as light hybrid, soft hybrid, micro hybrid, etc.), Moderate Hybrid, Full Hybrid (also known as strong hybrid, etc.), and Plug-in Hybrid.

How to Check the Tire Date?

Tire date can be found on the sidewall. Below is relevant information about car tires: 1. Tire Function: Car tires are one of the important components of a vehicle, directly contacting the road surface and working with the suspension to mitigate impacts during driving, ensuring good ride comfort and smoothness; maintaining excellent adhesion between the wheels and the road; improving traction, braking, and off-road capability; bearing the vehicle's weight. The crucial role tires play in automobiles is increasingly recognized. 2. Tire Classification: Full-size spare tires have the exact same specifications as the other four tires on the vehicle and can replace any temporarily or permanently unusable tire. Non-full-size spare tires: These spare tires have slightly smaller diameter and width compared to the other four tires, thus only serving as a temporary replacement and must be used on non-driving wheels with a maximum speed not exceeding 80km/h.

What does the National IV logo refer to?

IV is a Roman numeral, corresponding to the Arabic numeral 4, so National IV is the National 4 standard. Here are the methods to check which national standard a car belongs to: 1. Check the back of the car's environmental protection label. 2. Estimate the car's emission standard based on its production year. 3. Take the vehicle registration certificate to the local DMV for inquiry. 4. Check the emission standard description on the vehicle qualification certificate. The national standard refers to the National Motor Vehicle Pollutant Emission Standards, which regulate the content of harmful gases such as carbon monoxide, hydrocarbons, nitrogen oxides, particulates, and carbon smoke emitted from vehicle exhaust.
