Small steel balls in the axle can reduce friction. Automotive bearings are fundamental components in the vehicle's transmission system, bearing both axial and radial loads, making them crucial parts. Automotive bearings constitute a significant portion of the bearing industry, including wheel hub bearings, air conditioning fan bearings, and pulley bearings. Bearings primarily serve two functions: 1. Maintaining steering flexibility: They ensure that the shock absorber rotates with the wheel during steering, maintaining steering agility. 2. Shock absorption: The outer ring of the pressure bearing is made of rubber, providing a flexible connection between the vehicle body and the shock absorber. This prevents vibrations from uneven road surfaces from being transmitted through the shock absorber to the vehicle body during driving.

What Are the Effects After Repairing a Water-Damaged Engine?

Here are the impacts of repairing a car engine after water ingress: Engine failure: Driving through deep puddles can cause severe damage, leading to the destruction of engine pistons and connecting rods. After the vehicle has been submerged, the water entering the engine accelerates rusting of internal moving parts under high temperatures. Excessive water intake can cause deformation, and in severe cases, the engine may be rendered unusable. Bacterial growth inside the car: After water enters the vehicle, interior components are prone to mold and deterioration. During hot summer weather, various unpleasant odors may develop inside the car.

Can the Crankshaft Ventilation Pipe Be Removed?

Crankshaft ventilation pipe can be removed, but it is not environmentally friendly, and the throttle body and idle valve are more likely to get dirty, which will affect exhaust emissions and engine efficiency. Function of the Vehicle Ventilation Pipe: The main function of the vehicle ventilation pipe is to extract exhaust gases in certain specific engines, redirecting part of the exhaust gases back to the intake manifold, where they mix with fresh air-fuel mixture and re-enter the cylinders to participate in combustion, thereby improving emissions. Impact on Engine Performance: If the ventilation pipe is not connected to the exhaust valve, it will be impossible to control the amount of exhaust gas recirculation. Excessive exhaust gas recirculation will affect the ignition and performance of the air-fuel mixture, thus impacting the engine's power output, especially during idle, low speed, light load, and cold engine conditions, where recirculated exhaust gases will significantly affect engine performance.

Can the car pickup be postponed for several months after ordering?

No. The following is an introduction to full payment and installment payment for car purchases: Full payment: Generally, there are no additional fees such as handling charges or deposits when paying in full, making it relatively more cost-effective. However, the financial pressure of paying the entire amount at once is significant, which most families cannot afford. Installment payment: Installment payment is currently the most common method of purchasing a car. After signing a car loan agreement with the bank, it typically involves 36 months of monthly payments. After paying the down payment, the monthly installments are paid accordingly. During this period, corresponding interest fees will be incurred, resulting in a higher overall cost for the car. However, the financial pressure is relatively smaller.

Why Are Engines Made of Aluminum?

Engines are made of aluminum for the following reasons: Lightweight: The advantage of an aluminum engine block is its lightweight, which helps improve fuel efficiency. For engines of the same displacement, using an aluminum block can reduce weight by approximately 20 kilograms. Reducing a car's weight by 10% can lower fuel consumption by 6% to 8%. According to recent data, the weight of foreign cars has decreased by 20% to 26% compared to the past. Improves Engine Efficiency: For example, the Ford Focus uses an all-aluminum construction, which not only reduces the vehicle's weight but also enhances the engine's cooling performance, improving efficiency and extending its lifespan. From a fuel-saving perspective, the advantages of aluminum engines in fuel efficiency have garnered significant attention.

What are the reasons for the disc brake caliper piston not retracting?

Here are the reasons for the disc brake caliper piston not retracting: Brake pedal malfunction: Aging of the brake pedal can cause the pedal's spring or screws to become loose, resulting in symptoms such as slow or incomplete brake return. A detailed inspection of the car's pedal is required, and damaged parts should be replaced promptly. Low brake pump pressure: There are many reasons for low brake pump pressure, including blockage in the brake system management or air leaks in the brake booster. It is necessary to visit a repair shop or 4S store for professional inspection and repair. Lack of brake fluid: Insufficient brake fluid is a major cause of incomplete brake return. It is important to check the brake fluid regularly and replace or replenish it as needed.

What is the reason for the car being weak and slow after replacing the controller?

The reasons for the car being slow after replacing the controller are as follows: Battery aging: A new battery has sufficient power, providing strong performance and fast speed. However, after a year of use, the battery's capacity to hold charge may decrease, and it may deplete quickly even after a full charge. Battery quality: When purchasing an electric vehicle, it is essential to choose a high-quality battery and not opt for cheaper alternatives, as they often lack good quality. Some batteries may look good externally but have poor internal quality. Temperature effects: The performance of an electric vehicle's battery also varies between summer and winter. The battery performs better in summer, allowing for longer distances. In winter, due to temperature effects, the battery's capacity to hold charge decreases, resulting in reduced mileage for the owner.
