How many engine warning lights are there?

Generally, there is only one indicator light, which is the engine malfunction warning light. Fault indicator light: The engine fault signal is issued by the ECU, which controls all electronic components of the engine. The flashing of the engine warning light may indicate a malfunction in a certain engine component, which is an abnormal condition. Reasons for the warning light: If the warning light is on but there are no noticeable driving abnormalities, it might just be a sensor malfunction. In this case, you can continue driving temporarily, but it's advisable to drive at low to medium speeds cautiously. If the engine warning light comes on and the vehicle exhibits severe shaking, loss of power during acceleration, etc., immediate assistance is required. If the car cannot start, it might be due to a fuel pump or ignition component failure, in which case you should call for help.

How long can the car be turned off after jump-starting when the battery is dead?

After jump-starting when the car battery is dead, it can be turned off after more than 1 hour. Before turning off the engine, make sure to turn off all electrical devices. If a car battery remains unused for a long time, it will gradually self-discharge until it becomes unusable. Therefore, the car should be started periodically to recharge the battery. Car battery maintenance methods include: 1. Turn off lights and audio before parking and shutting off the engine; 2. Avoid leaving the air conditioning on when turning off the engine; 3. Drive the car for a certain distance periodically; 4. Clean the battery regularly; 5. Prevent battery drain; 6. Check the battery every six months; 7. Monitor the battery status indicator promptly.

How Many Kilometers Should Spark Plugs Be Replaced in a Family Car?

Under normal maintenance conditions, spark plugs in family cars should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. The following standards can be referenced for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Methods to determine if a spark plug is damaged: Remove the spark plug and observe its appearance to assess its condition. A normal spark plug's insulator skirt and electrodes should appear gray-white, gray-yellow, or light brown. A properly functioning spark plug's insulator skirt should be reddish-brown, with an electrode gap between 0.8-0.9mm and no signs of electrode burning. If the spark plug has oil stains or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, showing signs such as blistering at the tip, black streaks, cracks, or melted electrodes, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected or the air-fuel mixture is too rich, with oil seeping up.

What are the reasons why a motorcycle cannot shift gears?

Motorcycle cannot shift gears may be due to gear lever failure, gear hook spring breakage, or faults in the shift drum or star gear. Correct gear shifting steps: Starting: After the engine is started, it needs to warm up for 3 to 5 minutes before starting to move; Gear shifting: During the time when the clutch is "disengaged" for gear shifting, it is a "free travel interval", where neither acceleration nor throttle control can be used to adjust the motorcycle's speed, and the motorcycle can only move by "inertia". Driving method: Motorcycles are two-wheeled or three-wheeled vehicles driven by gasoline engines, steered by handlebars to control the front wheel. They are lightweight, flexible, fast, and widely used for patrol, passenger and cargo transportation, and also serve as sports equipment. Broadly speaking, motorcycles are divided into street bikes, road racing motorcycles, off-road motorcycles, cruisers, touring bikes, etc.

What Causes Car Jerking When the AC is Turned On?

Car jerking when the AC is turned on may be caused by severe carbon buildup in the engine cylinders. Fuel supply malfunction: Engine logic error: Unable to receive the AC activation signal. When the system cannot determine whether the AC is turned on, the Engine Control Unit (ECU) mistakenly interprets it as a temporary high load and attempts to compensate by increasing the RPM to offset idle resistance. When the engine RPM drops, it cannot handle the load from the AC compressor, causing the RPM to rise again. This back-and-forth results in unstable idling. AC control circuit malfunction: Unable to send the AC activation signal. Similar to the first scenario, since the system cannot determine the AC's operational status, the ECU continuously adjusts the idle RPM, leading to unstable idling.
