Is the Three-Way Catalytic Converter Cleaner Useful for Cars?

For mild three-way catalytic converter blockages, the three-way catalytic cleaner is significantly effective. Here is an introduction to the use of the three-way catalytic cleaner: 1. The function of the three-way catalytic cleaner is to remove chemicals such as sulfur and phosphorus from the surface of the three-way catalytic converter, unclog the exhaust pipe, and restore the activity of the three-way catalytic converter. However, for more severe blockages, the cleaner alone may not be very effective. In such cases, disassembly and cleaning may be necessary, and if there is damage or severe blockage, direct replacement is required. 2. The cleaning solution is drawn into the engine through the intake vacuum tube via a tool, passes through the combustion chamber and exhaust pipe to reach the three-way catalytic converter. At a certain temperature, it reacts chemically with the deposits on the surface of the three-way catalytic converter to achieve the cleaning purpose.

How to Distinguish Between Low Beam and High Beam Headlights?

Both high beam and low beam headlights are used to illuminate the road ahead of the vehicle. The methods to distinguish between low beam and high beam headlights are as follows: 1. Identify by the difference in icons. The light lines of the low beam icon point downward, while the light lines of the high beam icon point straight forward. 2. Identify by the difference in illumination distance. The low beam illuminates a distance of approximately 30-40 meters, while the high beam can illuminate higher and farther. 3. Identify by the difference in usage. Low beams are generally used on well-lit roads or when meeting other vehicles, while high beams are used on poorly lit roads.

What are the reasons for the ATSL engine warning light to come on?

The main reasons for the engine warning light to illuminate include sensor issues, car maintenance problems, fuel quality issues, poor combustion of the air-fuel mixture, engine intake problems, turbocharging problems, exhaust problems, and anti-theft system malfunctions. In addition, when starting the car, the vehicle performs a self-check on the engine system. Normally, the engine warning light will turn off after the self-check is completed. If it remains on for an extended period, it is advisable to seek professional help at a repair station to diagnose and eliminate potential safety hazards. Below is a detailed explanation of each type of fault: Sensor issues: Sensors include coolant temperature, crankshaft position, air flow, intake temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruptions, the car's ECU cannot accurately obtain engine data, which triggers the engine warning light. In such cases, it is important to visit a repair center for professional diagnosis and timely elimination of safety hazards. Maintenance issues: Poor engine maintenance is the most common cause of the engine warning light illuminating. Vehicles have specific maintenance cycles, and failure to adhere to these cycles, combined with poor driving habits, can increase the burden on the engine. Eventually, the engine warning light will illuminate to alert the owner of a fault. Fuel quality issues: This refers to both fuel and engine oil. The fuel used in cars usually has a specific grade, and engine oil can be semi-synthetic or fully synthetic. Manufacturers typically recommend which fuel grade and oil type to use. If the owner fails to follow these recommendations, long-term use can lead to engine wear, causing the warning light to illuminate. It is essential to use the recommended fuel grade and appropriate engine oil. Poor combustion of the air-fuel mixture: Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion of the air-fuel mixture in the engine. This leads to engine carbon buildup or knocking, which is detected by the oxygen sensor and reported to the ECU, triggering the warning light as a warning. Intake problems: The engine requires air for combustion, and the air filter plays a crucial role in this process. If the air filter is dirty or not cleaned regularly, it can affect the engine's air intake, potentially leading to blockages. In severe cases, this can cause the engine warning light to illuminate. Turbocharging problems: Issues with the intake turbocharging pipeline or turbocharger can also cause the engine warning light to come on. The most common issue is a damaged turbocharger, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. Exhaust problems: Faults in the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings can trigger the engine warning light. The most common issue is a malfunctioning catalytic converter, often caused by using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, or fuel system faults. Anti-theft system: If the car's electronic anti-theft system malfunctions or the anti-theft controller does not match the engine's electronic controller, the anti-theft system can prevent the engine from operating normally, causing the warning light to illuminate. When the engine warning light comes on, there are two scenarios: a yellow light indicates a warning, meaning certain system parameters may be out of the set range. The car can still be driven, but some functions may be limited. A red light is a prohibition, meaning the car must be stopped immediately, the engine turned off, and further driving avoided until the fault is checked. Solutions for the engine warning light: Check the spark plugs and ignition wires. Ensure the spark plug gap meets the manufacturer's technical specifications and the resistance of the ignition wires complies with technical requirements. Adjust or replace them if necessary. Perform a fuel pressure system check. Inspect the fuel pressure gauge and its components, connect the fuel lines and gauge. Start the engine and let it idle. The fuel pressure reading should be between 270-320 kPa. If the pressure is outside the specified range, replace the fuel pressure regulator and fuel filter.

What type of oil does the Senova D50 use?

Models equipped with the 1.5L naturally aspirated engine use 30-viscosity full synthetic oil, while models with the 1.5L turbocharged engine use 40-viscosity full synthetic oil. Here is an introduction to engine oil: 1. Full synthetic oil: The base oil of this type of oil is artificially synthesized. The molecular size and shape of full synthetic oil are nearly identical, providing superior lubrication performance and a longer service life. 2. Engine oil is referred to as the "blood" of the engine. Inside the engine, it not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. 3. During normal engine operation, the oil forms a stable film on the surfaces of various engine components, preventing direct contact and friction between parts. 4. If the oil viscosity is too low, it cannot form a stable film, which will accelerate engine wear. If the oil viscosity is too high, the resistance during engine operation increases, negatively affecting power output and fuel economy.

What to Do When the Car Malfunction Light Comes On?

When the car malfunction light comes on, it indicates that there is a fault in the corresponding part, which requires timely inspection and repair. Specific malfunction lights are as follows: 1. Air Filter Malfunction Light. It indicates that the engine air filter has excessive intake resistance. The solution is to stop the car, clean or replace the air filter until the light goes off. 2. Power Steering System Malfunction Light. It may indicate an issue with the wiring or oil circuit. The solution is to drive at low speed as much as possible and promptly take the car to a repair shop for inspection. 3. Light/Rain Sensor Malfunction Light. It indicates a fault with the light/rain sensor. The solution is to promptly take the car to a repair shop for inspection.

What does Subject 2 test include?

Subject 2 test content: For small vehicles, C1 test items include five mandatory tests: reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-curves). Some regions also include a sixth item: highway toll card collection. C2 test items include four mandatory tests: reverse parking, parallel parking, right-angle turns, and curve driving (commonly known as S-curves). For large vehicles (A1, A2, A3, B1, B2), test items include pole test, stopping and starting on a slope, parallel parking, driving over a single-plank bridge, curve driving, right-angle turns, passing through a narrow gate, driving over continuous obstacles, driving on bumpy roads, U-turns on narrow roads, as well as simulated highway driving, continuous sharp turns on mountain roads, tunnels, rainy (foggy) weather conditions, slippery roads, and emergency handling. Subject 2 test rules: All five test items must be passed in one attempt for the test to be considered successful. There are two test opportunities in total, meaning one initial test and one retest. If the first test is failed, a retest is conducted immediately. Those who fail the retest must wait 10 days before scheduling another test. After the test, candidates must leave the test site promptly and must not interfere with other test-takers.
