What Causes Vehicle Body Shaking While Driving?

Vehicle body shaking while driving can be caused by: 1. Low ignition energy. During startup, especially when the temperature of fuel and lubricating oil is low, more throttle is needed to meet power demands. Over time, the electrode gap of the spark plugs gradually increases, leading to a decrease in ignition energy and poor fuel atomization, which results in body shaking; 2. Aging ignition coils, high-voltage wires of spark plugs, or electrical leakage can also reduce ignition energy; 3. Abnormal engine coolant temperature, low cylinder pressure, or clogged fuel injectors. If the vehicle shakes upon startup, it is recommended that the owner promptly take it to a 4S shop for inspection and repair.

How Often Should the Three-Way Catalytic Converter Be Replaced?

The three-way catalytic converter should be replaced every 30,000 kilometers. The three-way catalytic converter is an important external purification device installed in the vehicle's exhaust system. It converts harmful gases such as CO and HC in vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Symptoms of a faulty three-way catalytic converter include: 1. The engine malfunction indicator light will illuminate when the engine's electronic control unit (ECU) fails to detect or detects abnormal signals from the oxygen sensor; 2. Increased fuel consumption and reduced power; 3. Blockage of the three-way catalytic converter, which can easily lead to excessive engine temperature; 4. Severe imbalance in the air-fuel ratio of the combustible mixture in the cylinders, causing incomplete combustion and resulting in a large accumulation of carbon deposits in the cylinders, thereby increasing carbon buildup.

How to Scrap a Vehicle?

To scrap a vehicle, follow these steps: 1. The vehicle owner must bring their identity proof, vehicle registration certificate, vehicle license, and license plates to the business department of an authorized vehicle dismantling factory and fill out the Vehicle Deactivation Registration Application Form. 2. Wait for notification at the license and certificate management counter for fee payment and license plate surrender. 3. Apply at the registration acceptance counter, where a Vehicle Scrapping Notice will be issued for vehicles that have reached the scrapping age limit. 4. The owner can then choose a qualified recycling company to deliver the vehicle for dismantling. 5. Present the recycling company's inspection notice to dismantle the vehicle and take photographs. 6. The owner must submit the modification form, vehicle scrapping and recycling certificate, and dismantling photos to the vehicle inspection counter for verification and signature. The license and certificate will be reclaimed, and the scrapping registration will be processed after approval according to regulations.

What are the reasons why the car won't start?

The reasons why the car won't start are: 1. Battery damage: If this is the reason, it needs to be sent to a repair shop for detection by professional computer equipment. In addition, it may also be due to battery depletion. If you often drive at low speeds in the city and frequently use devices such as headlights, air conditioning, and audio, battery depletion may occur; 2. Abnormal air-fuel mixture in the car: This phenomenon occurs when the throttle or idle speed motor is too dirty. If the valve is too dirty, fuel will spray onto the back and be absorbed by carbon deposits; 3. Unstable power supply voltage of the ignition system: In winter, the car's starting resistance is high, including insufficient battery power, which leads to insufficient voltage in the entire ignition system.

What Causes Motorcycle Engine Oil Leakage?

Motorcycle engine oil leakage is primarily caused by improperly installed oil filters or potential leaks in the engine's sealing gasket. When this issue occurs, it is necessary to inspect both the oil filter and the engine's sealing gasket. Solutions for motorcycle engine oil leakage include: 1. Replacing the oil pan or repairing it with aluminum repair compound; 2. Replacing the sealing paper gasket. Engine oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. Engine oil is used for lubricating internal combustion engines, with its main functions being to reduce friction and wear on moving parts and to remove sludge and varnish from the engine.

What is Automotive Primer?

Automotive primer is the first layer of coating directly applied to the surface of treated vehicle components, serving as the foundation of the entire paint system. It is designed to have excellent adhesion to the substrate, good compatibility with intermediate or top coats, and must also possess superior corrosion resistance, rust prevention, oil resistance, chemical resistance, and water resistance. Automotive primers can generally be categorized into dip primers, water-based dip primers, anodic electrodeposition primers, and cathodic electrodeposition primers. The functions of automotive primer include: 1. Filling capillary pores in the steel plate to facilitate surface painting; 2. Ensuring the top coat can adhere tightly to the vehicle surface.
