How Often Should Engine Carbon Deposits Be Removed?

Engine carbon deposits should be removed approximately every 10,000 kilometers. The causes of engine carbon deposits are: 1. Long-term poor driving habits of the owner; 2. Mismatch between fuel grade and compression ratio; 3. Aging or damage to the engine carburetor; 4. Prolonged high-load driving; 5. Not replacing the air filter; 6. Inaccurate ignition timing or fuel supply timing; 7. Low engine temperature; 8. Poor sealing of valves and valve seat rings; 9. Prolonged engine idling. Methods to prevent engine carbon deposits include: 1. Regularly cleaning components prone to carbon buildup; 2. Avoiding prolonged idling; 3. Using suitable gasoline additives; 4. Using the gasoline specified for the vehicle.

Can a New Car Frequently Drive on Highways?

A new car can drive on highways, but not too frequently, and the speed should not exceed 100km/h. Here are some precautions for using a new car: 1. Cold start warm-up: Proper warm-up helps form an "oil film" between engine components, reducing wear. 2. Timely gear shifting: When driving a manual transmission car during the break-in period, shift gears promptly and appropriately to avoid incorrect behaviors like high gear with low RPM or low gear with high RPM, and do not use a single gear for extended periods. 3. Timely maintenance: Simply follow the manufacturer's recommendations in the vehicle manual, and perform inspections and maintenance, such as changing engine oil and oil filters, and thoroughly checking the chassis system after reaching certain mileage or time intervals. 4. Avoid emergency braking: Emergency braking not only impacts the braking system during the break-in period but also increases the load on the vehicle's chassis and engine.

Which gear should be used when driving an automatic transmission car uphill?

Automatic transmission cars can use D gear or S gear when going uphill. The following is a detailed introduction to gear selection for different road conditions: 1. Uphill: This type of road section requires high torque intervention, and you can use "D-" to downshift. However, sometimes when there is sufficient power, it is also necessary to use "D+" to upshift to prevent power waste and damage to the engine and transmission. When encountering steep slopes, even after downshifting, you may still experience insufficient vehicle power. In this case, use the S gear (sport mode). 2. Downhill: Use "D+" to shift up to D2 or D3 gear, which can restrain the engine to achieve a braking effect. Generally, gears 2-3 are sufficient for moderate slopes, but when encountering steep slopes, pay attention to switching to gear 1. If the vehicle starts sliding faster, you should also use "D-" to downshift and control the vehicle.

What should be the tire pressure for front tires?

The tire pressure for front tires should be around 2.3 bar. Car tire pressure refers to the air pressure inside the tire. The effects of abnormal tire pressure are: 1. Reduced friction and adhesion of the tire, affecting braking performance; 2. Causes steering wheel vibration and deviation, reducing driving comfort; 3. Accelerates localized wear of the tread pattern in the center of the tire, shortening tire lifespan; 4. Increases body vibration, indirectly affecting the lifespan of other components. Methods for tire maintenance include: 1. Avoiding curbs and potholes to prevent sidewall ply breakage leading to tire bulges; 2. Regularly removing debris from tire grooves to prevent blowouts; 3. Checking tire wear and replacing them in time; 4. Performing tire rotation to avoid excessive wear; 5. Regularly checking tire pressure, ensuring it is neither too high nor too low.
