The following parts need to be replaced at 20,000 kilometers for a car: 1. Replace engine oil and oil filter: Due to the harsh high-temperature and high-pressure environment inside the engine, the shelf life of engine oil is significantly shortened, and its performance greatly declines. Over time, it fails to protect the engine. The oil filter prevents impurities from mixing into the oil, which can cause oxidation, leading to the formation of gum and sludge that can clog the oil passages. Both the engine oil and oil filter should be replaced simultaneously. 2. Replace the air filter: If it was not replaced during the 10,000-kilometer maintenance, it must be replaced at the 20,000-kilometer maintenance. The air cleaner's function is to block dust and particles inhaled by the engine during the intake process. If the filter is not cleaned for a long time, it can lead to dust being sucked into the engine, causing abnormal wear on the cylinder walls. 3. Replace the spark plugs: If the car uses standard material spark plugs, preparations should be made to replace them at 20,000 kilometers. Spark plugs directly affect the engine's acceleration performance and fuel consumption. When you feel that the engine lacks power while driving, maintenance should be performed. The service life of spark plugs varies depending on the material used.

During my last maintenance at 20,000 kilometers, I specifically consulted the advice of an experienced mechanic. Engine oil and oil filter must be replaced—this is fundamental to ensuring smooth engine operation, so don't skimp on these small expenses. The air filter depends on the situation; since I drive on dusty roads often, I replaced it directly—it's not expensive anyway. The cabin air filter is recommended for replacement, especially for someone like me who frequently transports children—respiratory health is more important. Rotating the tires ensures even wear across all four wheels, extending their lifespan. Brake fluid needs to be checked for water content; if it exceeds 3%, it must be replaced. Coolant levels and color should also be inspected—top it up if it's low. Finally, have the mechanic check the chassis and suspension to ensure there are no unusual noises. A car is like a person—regular maintenance is key to keeping it running for a long time.

What Are the Symptoms of a Faulty Camshaft Sensor?

The manifestations of a faulty camshaft sensor include difficulty in ignition, hard starting, unstable idle, inability to accelerate, weak engine performance, increased fuel consumption, vehicle shaking, persistent illumination of the malfunction indicator light, sudden engine shutdown when the car is hot, jerky driving, and accelerated engine wear. Below is an introduction to the camshaft position sensor: 1. Working Principle: The camshaft position sensor is the main control signal for ignition. When the sensor shaft rotates with the crankshaft and the camshaft, the light-transmitting holes and opaque sections on the signal disk pass between the LED and the phototransistor. The light emitted by the LED is alternately blocked and transmitted by the signal disk, thereby alternately illuminating the phototransistor of the signal generator. This generates pulse signals corresponding to the crankshaft and camshaft positions in the signal sensor. 2. Function: The camshaft position sensor collects the position signal of the camshaft and inputs it into the ECU, enabling the ECU to identify the top dead center of the cylinder compression for sequential fuel injection control, ignition timing control, and knock control. Additionally, the camshaft position signal is used to identify the first ignition timing during engine startup.

What are the symptoms of a bent engine connecting rod?

If the engine connecting rod is slightly bent or deformed, it may result in the engine failing to start. After starting, the engine may exhibit unstable idling, severe shaking, and accompanied by knocking sounds. Additionally, professional tools are required for measurement, which needs to be conducted at a repair shop. Extended Information: The following are the causes of a bent engine connecting rod in a car: 1. Water entering the engine cylinder: As the amount of water increases, it accumulates on top of the piston, reducing the effective volume of the combustion chamber, increasing compression resistance, and consequently increasing the pressure transmitted from the piston to the connecting rod. 2. Abnormal engine fuel injection system: This situation is usually caused by continuous fuel injection from one of the engine's injectors. Symptoms often include difficulty starting, unstable idling, black smoke from the exhaust pipe, and reduced power. 3. Connecting rod seizing with the crankshaft: This is generally caused by poor engine lubrication and can be determined by checking the wear condition of internal engine components. 4. Issues with the connecting rod itself: This can usually be confirmed through methods such as chemical composition analysis of the connecting rod material, hardness testing, metallographic examination, and scanning electron microscope fracture analysis.

What is the Difference Between a Used Car with 2 and 3 Ownership Transfers?

Here are the differences between a used car with 2 and 3 ownership transfers: 1. Different number of transfers: A used car with two ownership transfers is considered a second-hand vehicle in China. A car with three ownership transfers has undergone three sales transactions, meaning three transfer procedures. 2. Different values: As the number of ownership transfers increases, the selling price of the car tends to decrease. The most significant selling point of used cars is their affordability. With the same amount of money needed to buy a new car, you can purchase a higher-grade used car. A car with three ownership transfers is even cheaper than a regular used car. 3. Different safety levels: Used cars can still be used until they reach the national scrapping standards or the end of their economic service life. However, cars with three ownership transfers generally have a shorter lifespan, and their corresponding safety performance may also decline.
