What causes a loud noise when driving over a pothole without slowing down?

Reasons for abnormal noise when driving over potholes: First, check the shock absorber for faults by inspecting whether it is leaking oil. Below is an introduction to abnormal noises in cars: Car half-shaft issues: Due to long-term torsional fatigue and impact forces, the car's half-shaft is prone to bending, twisting, breaking, or wear and skew of the spline teeth. This can cause the car to shake rhythmically when accelerating within a certain speed range, accompanied by noise. The shaking disappears or lessens when the accelerator is released. Engine belt looseness: A slipping belt will produce abnormal noise. Once the belt slips, it leads to friction and high temperatures, causing the belt to stretch further and slip more severely, creating a vicious cycle. In this case, it is necessary to adjust the belt at a repair shop.

Will Installing a High-Flow Air Filter Affect Engine Lifespan?

Installing a high-flow air filter can impact engine lifespan. An air filter is a type of filtration device. During operation, engines intake large volumes of air. If this air isn't properly filtered, dust particles suspended in the air may enter the cylinders, accelerating wear on piston assemblies and cylinder walls. An engine is a machine that converts other forms of energy into mechanical energy, originally developed in England. It serves both as a power generation device and can refer to the complete machine including the power unit. Engine operation follows a four-stroke cycle: intake stroke, compression stroke, power stroke, and exhaust stroke.

What to Do When the Tire Has a Small Cut?

The solution for a small cut on the tire is to have it repaired at a professional repair shop. Car tires are one of the important components of a vehicle, directly in contact with the road surface. Together with the car suspension, they help absorb shocks while driving, ensuring good adhesion between the wheels and the road, improving the vehicle's traction, braking, and off-road capability, as well as bearing the weight of the car. When buying tires, pay attention to: 1. Determine the appropriate tire type for your car; 2. Know the tire size, usually marked on the side of the tire; 3. Check if the purchased tire is a retreaded one and note the production date of the tire.

Is Vehicle Purchase Tax Paid Before New Car Registration?

What does ESP mean?

ESP refers to the Electronic Stability Program, a general term for systems or programs designed to enhance vehicle handling performance while effectively preventing loss of control when the vehicle reaches its dynamic limits. ESP includes functions such as Electronic Brakeforce Distribution (EBD), Anti-lock Braking System (ABS), Traction Control System (TCS), and Vehicle Dynamic Control (VDC). The principle of ESP is: through the ABS electronic control unit, based on signals from the wheel speed sensors, the system calculates and analyzes to determine the wheel slip rate and vehicle speed. The electronic control unit then adjusts the wheel slip rate by controlling the throttle opening and brake pressure.

What is the China IV Emission Standard?

The China IV Emission Standard is the fourth phase of national standards for motor vehicle pollutant emissions. The main pollutants emitted by vehicles include HC (hydrocarbons), NOx (nitrogen oxides), CO (carbon monoxide), and PM (particulate matter). Through the application of technologies such as improved catalytic converter active layers, secondary air injection, and exhaust gas recirculation systems with cooling devices, the standard aims to control and reduce vehicle emissions below specified limits. Compared to previous standards, the China V standard imposes stricter limits on nitrogen oxides, hydrocarbons, carbon monoxide, and suspended particles. From China I to China IV, each upgrade in the standard reduces single-vehicle pollution by 30% to 50%.
