Does the throttle need cleaning?

Throttle cleaning is necessary. The steps for cleaning the throttle are as follows: 1. Open the front hood, locate the engine and the air filter tube, and loosen the clamp screw on the engine side of the air filter tube; 2. Spray the cleaning agent onto the electronic throttle and wipe it with a cloth. Repeat the process, and use cotton swabs to clean hard-to-reach areas; 3. Turn the car key to the 'on' position and continue wiping until the black deposits inside are completely cleaned; 4. Reinstall the clamp on the air filter tube and tighten it. The throttle is a controllable valve that regulates the air entering the engine. There are two types: traditional cable-operated and electronic throttles. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture for combustion and power generation. The throttle is connected to the air filter at the top and the engine block at the bottom, often referred to as the 'throat' of the car engine.

How to Detect Engine Carbon Buildup?

Signs of engine carbon buildup include: 1. Difficulty starting the engine multiple times when cold, but normal when hot; 2. Unstable engine idling, with fluctuating RPMs; 3. Feeling sluggish and unresponsive while driving, especially noticeable when overtaking with slow acceleration response; 4. Pungent exhaust fumes exceeding emission standards; 5. Increased fuel consumption. Methods to clean engine carbon buildup are: 1. Intravenous cleaning: Hang a bottle-shaped tool above the engine, pour cleaner into it, and introduce it into the engine through a tube to clean the carbon buildup; 2. Machine cleaning: Inject cleaner into a machine, use the machine to pressurize it into the combustion chamber, allowing the cleaner to react with and dissolve the carbon buildup, then extract the waste liquid.

Should Roewe Use 92 or 95 Octane Gasoline?

Roewe vehicles should use 92 octane gasoline, as this fuel grade is recommended in the official vehicle user manual. In addition to checking the appropriate gasoline grade in the user manual, the fuel cap will also indicate the recommended grade. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with a compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. If the compression ratio is higher, 98 octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the gasoline grade, as high-compression engines can also be tuned to use lower-octane gasoline. Other factors, such as ignition timing, turbocharging technology, and Atkinson cycle technology, also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade in a Roewe, simply switch back to the correct grade after refueling. However, long-term use of the wrong gasoline grade can have the following effects: Using a higher octane gasoline in a vehicle designed for lower octane will not cause damage, but the increased octane can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using a lower octane gasoline in a vehicle designed for higher octane can cause engine knocking. The significantly lower octane reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unevenly. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine issues, affecting driving stability and causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring.

How to Replace a Damaged License Plate?

If your license plate is damaged, you should go to the vehicle management office to replace and obtain a new one. The specific method is as follows: Bring your original ID card and its copy, the vehicle registration certificate, the vehicle license, and the damaged license plate to the motor vehicle service hall of the vehicle management office where the vehicle is registered. There, you can obtain an application form, fill it out completely, pay the required fee, and then proceed with the replacement. Generally, it takes about three days to receive the new license plate. License plates, commonly known as tags, refer to vehicle registration plates, which are used to number and register vehicles. They display the vehicle's registration number, registration region, or other relevant information. The main purpose of a license plate is to identify the region to which the vehicle belongs and to trace the vehicle's owner and registration information based on the plate.

Where to Check the Tire Pressure Monitoring Values on the Honda Avancier?

The tire pressure monitoring values on the Honda Avancier can be checked using a tire pressure gauge. When abnormal tire pressure is detected, a warning to check the tire pressure will appear on the dashboard. The Avancier is an SUV under GAC Honda, equipped with a 2.0T turbocharged engine featuring dual VTC variable valve timing technology and VTEC variable valve lift technology on the exhaust side, delivering a maximum power of 200 kW and a maximum torque of 370 Nm. The Avancier comes with a 9-speed automatic transmission with SBW electronic push-button shifting and offers three driving modes: Snow Mode, Sport Mode, and Comfort Mode. It is also equipped with the Honda SENSING safety system, MVCS 360-degree panoramic imaging system, PA automatic parking assist system, and CTM rearview dynamic reminder system, making the driving experience more relaxed and safer.
