What Causes Abnormal Engine Vibration While Driving?

There are many reasons for abnormal engine vibration while driving, such as damaged spark plugs, poor fuel quality, excessive carbon deposits, unstable oil pressure, etc. Below are the explanations for abnormal engine vibration: 1. Worn gaps between spark plugs can lead to insufficient spark plug ignition, resulting in incomplete combustion of the air-fuel mixture, which causes the car to vibrate during acceleration. Additionally, if the ceramic part of the spark plug is cracked, the spark plug may fail to ignite, causing one cylinder to stop working and leading to acceleration vibration. In such cases, the spark plugs should be replaced. 2. Poor fuel quality can affect the atomization effect of the fuel injectors, leading to incomplete combustion of the air-fuel mixture in the cylinders and resulting in engine vibration and lack of power. It is recommended to use higher-grade gasoline after finishing the current tank and perform a fuel system cleaning. 3. Excessive dirt on the throttle body or carbon buildup on the fuel injectors can cause the throttle to not close properly or the idle speed control motor to get stuck, leading to excessively high idle speed. Carbon deposits generated during engine operation can also cause vehicle vibration, especially when starting the car—the engine may vibrate more intensely than usual or even fail to start on the first attempt. Therefore, when the vehicle experiences vibration, the throttle body and fuel injectors should be checked first. If excessive dirt or carbon buildup is found, they should be cleaned promptly.

What is the difference between 5w20 and 5w30?

The main difference between engine oils 5w20 and 5w30 lies in their high-temperature viscosity. The distinction between 5W-20 and 5W-30 is simply the difference in the latter numbers. 5w20 has lower viscosity (viscosity ranging between 5.6-9.3), which is relatively more fuel-efficient and provides a lighter driving feel, while 5W-30 has higher viscosity (viscosity ranging between 9.3-12.5), which is relatively more fuel-consuming and makes the throttle feel heavier, but results in quieter engine operation. Below is some relevant information about engine oil: 1. Viscosity is one of the most important characteristics of engine oil. Generally, the property of 'oil' is to thicken at low temperatures and thin at high temperatures, which is contrary to the actual working requirements of an engine. Additives can be used to alter the inherent nature of the oil. During cold starts at low temperatures, engine oil should have high fluidity (low viscosity) to quickly supply lubrication to all engine components, minimizing the time of insufficient lubrication before the oil completes its first circulation and reducing engine wear to the lowest possible extent. As the engine's operating temperature rises, the viscosity of the oil should not thin out, and the strength of the oil film should not diminish, ensuring complete lubrication. 2. The higher the viscosity of the engine oil, the more fuel the engine consumes, and the louder the noise, but the better the sealing performance. Therefore, when selecting engine oil viscosity, the age of the vehicle must also be considered. Newer vehicles have very small gaps between engine components, so oil with lower viscosity should be chosen, while vehicles with severe engine wear should opt for oil with higher viscosity.

What Are the Reasons Why the Car Key Cannot Start the Car?

Here are the reasons why the car key cannot start the car: 1. Steering wheel lock: The steering wheel lock is a normal anti-theft function. This situation occurs because the steering wheel was turned after the vehicle was turned off, usually from the straightened position to another direction. At this time, the car's computer will assume that the vehicle is being stolen and automatically activate the anti-theft function. Solution: Turn the steering wheel while turning the car key to start the car. For automatic transmission models, the brake must be pressed. Note: Apply some force but avoid using excessive force when turning the key—this requires some practice. If it doesn’t work the first time, try a few more times. 2. Incorrect gear position: For automatic transmission cars, the gear lever must be in the N (Neutral) or P (Park) position to start the ignition. This is a safety feature designed by the manufacturer. If the gear lever is not in N or P, the car may move immediately upon ignition, which is extremely dangerous. Solution: Shift the gear lever back to P and restart the ignition. One thing to note is that the transmission may experience "gear confusion," such as the gear lever being in N while the transmission is actually in D. If this happens, it is necessary to visit a 4S shop or a professional auto repair shop as soon as possible for repairs. 3. Car malfunction: Examples include engine failure, ignition system failure, relay damage, or a dead battery. A reminder: If the battery is dead and prevents the car from starting, there will be a squeaking sound during ignition, and the battery warning light and engine warning light on the dashboard will illuminate. Solution: In such cases, the only option is to seek help from a 4S shop. Let professionals inspect the issue first, determine the problem, and then proceed with targeted repairs based on the specific issue.

What is the first maintenance mileage for the Baojun 530?

Baojun 530's first maintenance is at 50,000 kilometers. The first maintenance items include: 1. Replace engine oil, oil filter, clean air filter, check whether the generator belt and wiper blades are damaged, check whether the levels of various fluids are normal, and check whether the tire pressure is normal; 2. Check the car chassis: including whether the brake pads, brake discs, connecting rods, ball joints, and ball cages are scratched; 3. Check whether all switches and lights in the car are working properly. Below is information about the first maintenance of a new car: 1. Check the tire wear condition and whether pressure adjustment is necessary. 2. Check the entire lighting system: headlights, indicator lights, emergency signal lights, trunk light, passenger compartment light, glove box light, dashboard warning lights, etc. 3. Check the operation of the windshield wiper, the position of the wiper blade, and its wear condition. 4. Check the condition of the exterior of the car body, the protective parts and pipes under the car body (exhaust-fuel lines-brake lines), and rubber parts (dust covers, bushings, spacers). 5. Check the condition of various control belts. 6. Check and adjust the height and travel of the clutch pedal. The clutch is a component we use frequently, so its inspection is very necessary. 7. Check and adjust the handbrake travel. 8. Check and tighten the chassis screws, as the chassis is inevitably impacted during driving, which may loosen the screws. 9. Clean the air filter element. The air filter plays a protective role for the air. 10. Refill various fluids (engine coolant, brake fluid, windshield washer fluid, etc.). 11. Replace the engine oil. 12. Replace the engine oil filter.

Does Gasoline Evaporate in the Fuel Tank?

Gasoline does evaporate in the fuel tank. Since the fuel tank is not a completely sealed device, a ventilation pipe is connected to the charcoal canister to prevent fuel splashing during refueling. The charcoal canister also has a pipe leading directly to the atmosphere. When the fuel tank is well-sealed, there will be minimal gasoline evaporation loss, primarily through the charcoal canister. Below are the relevant details: 1. Between the engine's intake manifold and the fuel tank, in addition to the main fuel supply line, there is a branch line equipped with a charcoal canister. When the engine is not running, the gasoline's evaporation characteristics create high pressure inside the fuel tank. Without the charcoal canister, these evaporated gasoline vapors would be released into the atmosphere through the tank's vent. With the charcoal canister installed, the activated charcoal inside promptly adsorbs these gasoline vapors, maintaining a balance between internal pressure and atmospheric pressure, preventing most vapors from remaining in the system. When the engine is running, these adsorbed fuel vapors are sent back into the engine for combustion via the solenoid valve at the charcoal canister's outlet, making full use of these vapors and improving fuel efficiency. 2. Due to gasoline's volatile nature, a significant amount of gasoline vapor is generated inside the fuel tank. To prevent resource waste and reduce atmospheric pollution, vehicles are equipped with a charcoal canister. Through connected piping, the gasoline vapors in the fuel tank enter the charcoal canister and are stored there. When the engine is running, the stored gasoline in the charcoal canister enters the engine for combustion. In other words, when the fuel tank is well-sealed, the loss of gasoline through evaporation is minimal and is reused.
