At how many kilometers does a car require major maintenance?

Generally, vehicles require a major maintenance service after traveling 30,000 kilometers. This involves replacing components such as engine oil, oil filter, air filter, fuel filter, power steering fluid, and spark plugs. Below is a partial introduction to major car maintenance: 1. Major maintenance builds upon minor maintenance, adding the replacement of air and fuel filters to the standard oil and oil filter change. These two filters serve to remove dust from the air and impurities from the fuel. 2. Most car engines utilize a dry-type air cleaner with a paper filter element, which is lightweight, low-cost, easy to replace, and highly efficient. It typically requires cleaning every 5,000 kilometers. 3. During routine car maintenance, technicians will perform additional inspections based on the vehicle's specific condition and may include other maintenance items, such as inspection and cleaning of engine-related systems, wheel alignment checks, and inspection of various fastening components.

How many kilometers should a new car drive before going on the highway?

New cars can go on the highway after driving about 500 kilometers. Generally, the break-in period is divided into three stages: 1. The initial stage is 0 to 500km, with the speed maintained at 60 to 70km/h; 2. The middle stage is 500 to 1000km, where the speed can be increased to 90 to 100km/h; 3. The later stage is 1000 to 2000km, where the speed can be increased to below 120km/h. Below is the relevant introduction: During the entire break-in period, it is necessary to control the speed and RPM, avoid aggressive driving, refrain from sudden acceleration, and avoid hard braking and sharp steering. Generally, after a 3000-kilometer break-in period, the car's power performance and fuel economy will be in a relatively good state.

What does A/C in a car mean?

Car A/C stands for: Car air conditioning device (air conditioning device), abbreviated as A/C. Air conditioning types are divided into the following categories: 1. By driving method: Independent type (driven by a dedicated engine to power the compressor, with large cooling capacity and stable operation, but high cost, large size and weight, mostly used in large and medium-sized buses) and non-independent type (the air conditioning compressor is driven by the car engine, cooling performance is greatly affected by the engine operation, with poor stability, mostly used in small buses and sedans). 2. By air conditioning performance: Single-function type (separate installation of cooling, heating, and ventilation systems, operated independently without interference, mostly used in large buses and trucks) and integrated heating and cooling type (cooling, heating, and ventilation share a blower and air duct, controlled on the same panel, which can be divided into combined type where heating and cooling work separately and mixed temperature adjustment type where heating and cooling can work simultaneously. Sedans mostly use the mixed temperature adjustment type). 3. By control method: Manual type (adjust temperature, wind speed, and direction by toggling function keys on the control panel) and electronically controlled pneumatic adjustment (using vacuum control mechanisms, when the air conditioning function key is selected, temperature and air volume can be automatically controlled within the preset range). 4. By adjustment method: Fully automatic adjustment (using calculation and comparison circuits, controlling adjustment mechanisms through sensor signals and preset signals to automatically adjust temperature and air volume) and fully automatic adjustment controlled by microcomputer (using a microcomputer as the control center to achieve comprehensive and multifunctional optimal control and adjustment of the in-car air environment).

What does AFW transmission fluid mean?

Aisin AFW6 is a type of transmission fluid, which is a lubricant used to maintain the cleanliness of the gear system. It ensures the proper functioning of the transmission and extends the lifespan of the transmission components. Depending on the structure of the transmission, transmission fluids are categorized into automatic transmission fluid (ATF) and manual transmission fluid (MTF). Below are some details about transmission fluid: 1. Transmission fluid is typically replaced every approximately 40,000 kilometers, as it can deteriorate and evaporate under high-speed and high-temperature conditions over time. 2. Failure to replace the transmission fluid can accelerate the wear and tear of mechanical components. Transmission fluid provides effective lubrication even in low-temperature conditions and reduces fluid loss under harsh operating conditions.

What Causes Intermittent Engine Shaking?

Engine intermittent shaking can be attributed to the following reasons: 1. Engine intake pipe leakage: The intake system contains numerous intake manifolds or valves. Any leakage can allow unintended gases to enter, causing the air-fuel mixture concentration in the intake manifold to become either too high or too low, ultimately leading to intermittent engine shaking or weak performance during idle. 2. Fuel system blockage or malfunction: Blockages in the fuel tank vent hole, fuel tank switch, fuel filter, or fuel lines between the tank and carburetor can prevent the engine from receiving the required fuel supply during idle. This results in a lean air-fuel mixture, weakened engine power output, and idle shaking. 3. Idle control valve failure: In fuel-injected engines, idle operation is primarily controlled by the idle control valve. The ECU adjusts the valve opening based on signals such as engine speed, temperature, and throttle position to maintain stable idle. If the valve malfunctions, it disrupts air distribution, causing uneven engine power during idle and resulting in vehicle shaking. 4. Engine carbon buildup: Carbon deposits in critical areas such as cylinders, throttle body, spark plugs, and intake valves directly impact engine power output. Excessive carbon buildup reduces ignition efficiency and intake air flow, leading to unstable engine power, idle shaking, and poor acceleration.

What are the differences between China 5 and China 6 vehicle emission standards?

China 5 and China 6 vehicle emission standards differ in the following aspects: 1. Different carbon monoxide emission levels: China 5 allows 1,000 mg of carbon monoxide emissions; China 6 permits 700 mg. 2. Different emission limits: China 5 has an emission limit of 0.0045 grams per kilometer; China 6's limit is 0.25 grams per kilometer. 3. Different issuing authorities: China 5 was issued by the Ministry of Environmental Protection; China 6 was jointly issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine. 4. Different letter representations: China 5 is denoted by V; China 6 is represented by VI.
