How to Measure the Condition of Spark Plugs?

Spark plugs may indicate the following symptoms when they are faulty: Difficulty in starting the car, whether cold or hot, often requiring multiple attempts. Engine shaking, noticeable during driving. Reduced power, with a significant drop in performance compared to normal conditions. Increased fuel consumption. Stalling. Failed emissions tests. Common causes and diagnostics of spark plug failures: Several conditions can lead to non-functional spark plugs: Incorrect spark plug gap adjustment. A gap that is too small limits the contact area between the spark and the air-fuel mixture and suppresses flame kernel growth due to the quenching effect of the electrodes, resulting in weak sparks and ignition difficulties. A gap that is too large may exceed the ignition system's voltage capacity, preventing sparking. Cracked spark plug skirt. High-voltage current leaks through the crack, preventing sparking at the electrodes. Electrode carbon buildup, 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 or chemical corrosion from combustion gases can cause electrode breakage, rendering the spark plug non-functional. Low insulation resistance of the spark plug. This reduces the ignition voltage across 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 disable that cylinder's spark plug. Eroded 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. Replacement steps are as follows: Open the hood, remove the engine's plastic cover, and disconnect the high-voltage wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove each spark plug, checking for and cleaning any debris like leaves or dust. Insert the new spark plug into the hole, hand-tighten it first, then use the socket to secure it. Reinstall the high-voltage wires in the correct firing order and replace the cover. Spark plug replacement interval: Typically replaced every 40,000-60,000 km under normal maintenance conditions, but this may vary by brand and engine type. Always refer to the owner's manual for specific recommendations.

What Causes the Engine Warning Light to Illuminate in Changan Vehicles?

The engine warning light may illuminate due to the following 7 main reasons: Sensor Malfunction: Sensors such as coolant temperature, crankshaft position, air flow, intake air temperature, and oxygen sensors may become damaged, have poor contact, or experience signal interruptions. When the vehicle's ECU cannot accurately obtain engine data, the engine warning light will illuminate. Fuel and Oil Quality Issues: Failure to use the fuel and oil specified by the manufacturer may cause engine wear, leading to the illumination of the warning light. Poor Combustion of Air-Fuel Mixture: Poor combustion can result in engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate as a warning. Issues such as faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion of the air-fuel mixture. Turbocharger Problems: Issues with the intake boost pipes or turbocharger can also trigger the engine warning light. The most common problem is a damaged turbocharger, accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Intake Problems: If there is an issue with the vehicle's air intake, it may lead to clogged engine pipes, and in severe cases, the engine warning light will illuminate. A dirty air filter that is not cleaned regularly can cause intake problems. Exhaust Problems: Exhaust system failures can also cause the engine warning light to illuminate. Common causes include faulty rear oxygen sensors, catalytic converters, exhaust camshafts, or bearings. The catalytic converter is the most frequently affected component. Using leaded gasoline, lead- or silicon-containing lubricant additives, physical damage to the catalytic converter, or fuel system malfunctions can easily lead to catalytic converter failure. Anti-Theft System Malfunction: If the vehicle's electronic anti-theft system malfunctions or if the anti-theft controller is incompatible with the engine's electronic controller, the anti-theft system can prevent the engine from operating normally, and the engine warning light will illuminate. If the engine warning light illuminates, follow these steps: First, check whether the engine is running normally. If there are issues like shaking or black smoke, avoid restarting the engine. Note: Do not restart the engine if the red warning light is on. If the engine can be started, turn it off and wait for 5-10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position without depressing the clutch. The vehicle will perform a self-check, and after 5-10 seconds, observe whether the warning light turns off. If the warning light remains on, visit a service center as soon as possible. Technicians can use a portable diagnostic tool to read the fault code, identify the issue, and perform targeted repairs.

Under What Circumstances Is It Considered Running a Red Light?

Determination is made through three photos captured by electronic cameras: a photo of the vehicle crossing the intersection stop line, including the traffic light showing red and the license plate number; a photo of the vehicle completely passing the stop line, including the traffic light showing red and the license plate number; and a photo showing the vehicle continuing to move, with a comparison to check if the vehicle's position has changed, including the traffic light showing red and the license plate number. Capturing these three photos confirms the vehicle ran a red light. The act of running a red light is clearly defined in the "Road Traffic Safety Law." Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage, and if a vehicle passes through an intersection during a red light, it constitutes the traffic violation of running a red light. Six scenarios of running a red light: Stopping immediately after crossing the line at a red light (when the red light turns on, the vehicle cannot stop in time, and the front of the vehicle crosses the stop line): If the vehicle only just crosses the stop line during a red light but stops immediately, this act of running a red light will not be penalized. However, if there is significant movement after crossing the line, penalties will apply. The three photos captured by electronic cameras for running a red light are: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all three photos are present will it be deemed as running a red light. Running a red light under police direction (the signal is red, but the traffic officer signals to proceed): When there is a conflict between the traffic signal and the officer's gesture, drivers must obey the officer's on-site command. If a driver runs a red light due to the officer's direction, they can obtain a diversion certificate from the local traffic police station to avoid penalties. If the driver disputes the penalty, they can appeal through administrative reconsideration or administrative litigation. Stopping after the entire vehicle crosses the line at a red light (failing to brake in time, causing the entire vehicle to cross the stop line): If the vehicle stops after completely crossing the stop line without further movement, it is not considered running a red light but is classified as stopping beyond the line. Reversing after stopping beyond the line (attempting to avoid penalties by reversing after stopping beyond the line at a red light): Vehicles are prohibited from reversing at railway crossings, intersections, one-way roads, bridges, sharp turns, steep slopes, or tunnels. Violations may result in warnings or fines. Accidentally running a red light behind a large vehicle (due to obstructed view by the large vehicle ahead, following it through the intersection): Drivers must maintain sufficient visibility to see the traffic signals ahead and ensure a safe braking distance. Generally, if a vehicle is photographed following a large vehicle through an intersection, it is due to rushing through the signal. Such behavior will be penalized as running a red light. Passing through an intersection during a yellow light (crossing the intersection when the signal turns yellow): Traffic authorities state that according to the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," vehicles that have already crossed the stop line when the yellow light flashes may continue to pass. If the yellow light is already on and the driver continues to rush through, it will be considered running a red light if captured.

What are the disadvantages of not having a catalytic converter?

The disadvantage of not having a catalytic converter is its impact on humans. Below are the relevant details: 1. Chemical reactions: The interior of a catalytic converter has no moving parts, and all cleaning operations are accomplished through ingenious chemical reactions. Inside the converter is a thick substrate with a fine grid-like cross-section, coated with precious metals such as platinum, palladium, and rhodium. 2. Catalysts: These precious metals are the actual catalysts involved in the reactions. Whether it's emissions, gasoline, diesel, or engine oil, they can react with these precious metals and quickly convert into less harmful substances, primarily nitrogen, carbon dioxide, and water.

How to Turn On the Auto Start-Stop Function in a Car?

To activate the auto start-stop function, the system automatically engages when the car is started. When the driver stops the vehicle by pressing the brake pedal, the engine shuts off automatically. Upon releasing the brake and pressing the accelerator, the engine restarts. The auto start-stop system is designed to automatically turn off the engine during temporary stops while driving, such as at traffic lights or in traffic jams, and restart it when resuming motion. This feature helps minimize unnecessary fuel consumption by reducing engine idling time. Additionally, shutting off the engine during stops effectively lowers noise and vibration, enhancing the overall driving experience.
