How to Test the Condition of Spark Plugs?

Spark plugs exhibit the following symptoms when they may be faulty: Difficulty in starting the car, both cold and hot starts are problematic, often requiring multiple attempts. Engine shaking, noticeable vibrations while driving the car. Lack of power, a significant decrease in performance compared to normal conditions. Increased fuel consumption. Stalling issues. Failed exhaust emissions tests. Common causes and diagnosis of spark plug failures: Several common issues can prevent spark plugs from functioning properly: Incorrect spark plug gap adjustment. A gap that is too small limits the contact area between the spark and the air-fuel mixture, and the flame kernel growth is suppressed by the electrode's flame quenching effect, resulting in weak sparks and difficult mixture ignition. Conversely, a gap that is too large may exceed the ignition system's voltage capacity, preventing spark generation. Cracked spark plug skirt. High-voltage current leaks through the crack, preventing sparks at the electrodes. Carbon buildup on electrodes, causing leakage from the center electrode to the surroundings instead of sparking to the side electrode. Excessive carbon deposits can short-circuit the spark plug, preventing sparks and damaging the insulator. Damaged electrodes. Prolonged electrical erosion from sparks or chemical corrosion from combustion gases can cause electrode breakage, preventing spark generation. Low insulation resistance of the spark plug. This reduces the ignition voltage applied to the spark gap, weakening or completely eliminating the spark. Short circuit in high-voltage wires. Leakage in the wire from the ignition coil to the distributor can prevent the entire engine from starting, while leakage in the wire from the distributor to a spark plug can prevent sparking in one cylinder. Burnt platinum contacts. This can prevent all spark plugs from firing, making the engine unable to start or run normally. Faulty spark plugs should be replaced promptly. The replacement steps are as follows: Open the engine hood, remove the plastic cover, and detach the high-voltage wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one, ensuring the surrounding area is free of debris like leaves or dust. Insert the new spark plug into the hole, hand-tighten it first, then use the socket to secure it. Reattach the high-voltage wires in the correct firing order and replace the cover. Spark plug replacement interval: Typically, spark plugs should be replaced every 40,000 to 60,000 kilometers under normal maintenance conditions, but this may vary by brand and engine type. Always refer to the vehicle's manual for specific recommendations.

What is a Car Dashboard?

The dashboard continuously reflects the operational status of the vehicle's internal machinery. Simultaneously, it serves as the control center for certain equipment and an object of decoration, making it the most eye-catching component in the driver's cabin. The dashboard assembly combines both technical and artistic functions, representing one of the defining features of the vehicle's overall style. Expanded functions of the dashboard: Most car dashboards belong to the third generation, which can drive the instrument pointer via a stepper motor or directly display graphics or text information using an LCD screen. Additionally, it includes an intelligent processing unit capable of exchanging information with other vehicle control units.

Can I still renew my driver's license if it has been expired for one month?

Yes! Generally, the renewal procedure for a driver's license should be completed within 3 months before its expiration date. If the driver's license is not renewed after its expiration, it will be considered invalid. In case of a traffic accident, the insurance company will not provide compensation. If the expiration period is less than one year, the renewal can be processed normally. If the license has been expired for more than one year but less than three years without renewal, the driver must take a written test at the DMV. Upon passing the test, normal renewal procedures can be resumed. If the driver's license has been expired for more than three years without renewal, the DMV will cancel the license.

How to Drive a Motor Vehicle on Mountain Roads?

Driving a motor vehicle on mountain roads requires the following techniques: 1. Uphill Driving. When driving uphill, maintain sufficient engine power to ensure the vehicle climbs smoothly; constantly monitor the coolant temperature gauge to prevent engine overheating. For prolonged climbs, the driver should remain patient and cautious, keeping the engine at adequate power for steady operation. If the coolant boils, choose a suitable location to take a brief rest, replenish the coolant, inspect the vehicle, and resume driving once the temperature drops. 2. Downhill Driving. Before descending, thoroughly check the braking and steering systems to ensure they are in good technical condition.

What is a reasonable starting RPM?

Starting RPM around 800 to 1000 is reasonable. A slightly higher starting RPM is normal, with most family cars typically starting between 1000 to 1500 RPM, though this may vary by vehicle model. However, during cold starts, the RPM should not be too high as the lubricating oil cannot reach the upper parts of the engine. To minimize wear, keeping it below 2000 RPM is advisable. Many manufacturers set a higher starting RPM to ensure sufficient power for the vehicle after shifting gears. RPM constantly reflects the engine's working condition. If the RPM is too low, fuel combustion in the cylinders may be incomplete, leading to carbon buildup in the engine, which can cause significant damage over time. Conversely, if the RPM is too high, it can also result in increased engine wear.
