What does a VVT engine mean?

What is the chassis number on the vehicle license?

The chassis number is the Vehicle Identification Number (VIN) on the vehicle license. Here are specific details about VIN: 1. The VIN is a 17-character code composed of letters and numbers, also known as the 17-digit identification code, chassis number, or 17-digit number. 2. Through permutation and combination, the vehicle identification code ensures that no two vehicles of the same model will have duplicate numbers within 30 years. 3. The VIN uniquely identifies a vehicle, hence it can be referred to as the "vehicle's ID card". Here is an introduction to the functions of the chassis number: 1. The chassis number follows specific rules: illegal characters include O, Q, I, and 0; the letter Z is invalid in the year position; the 9th digit can only be a number from 0-9 or the uppercase letter X; the following four digits must all be numbers and cannot be letters. 2. By analyzing the VIN standards and vehicle configuration, characters 4 to 8 represent the engine and transmission model, which must match the information on the assembly nameplate without any discrepancies.

How to Calculate Fuel Costs?

Calculation method for fuel cost per kilometer: Divide the refueling amount by the distance traveled. Here is a specific example of calculating fuel cost per kilometer: Refueling 200 yuan and driving 400 kilometers results in a fuel cost of 0.5 yuan per kilometer. The specific calculation method is 200/400=0.5 yuan. Here is another way to calculate fuel costs: 1. Calculate through fuel consumption per 100 kilometers. 2. If you want to calculate the cost per kilometer, it is fuel consumption multiplied by fuel price divided by 100 kilometers. For example, if you refuel 100 yuan and drive 100 kilometers, then the vehicle's cost per kilometer is 1 yuan. If gasoline is 6 yuan per liter, then 100 yuan divided by 6 yuan means about 16L of gasoline was added, so the vehicle's fuel consumption per 100 kilometers is 16L. The cost per kilometer is 1 yuan.

Differences Between the Qashqai and the X-Trail?

Here are the differences between the Qashqai and the X-Trail: 1. The X-Trail's body weight is approximately 100 kg heavier than the Qashqai. With the same engine and transmission, the Qashqai has slightly better power performance. 2. The X-Trail features a panoramic sunroof that can be opened, while the Qashqai's panoramic sunroof cannot be opened. 3. The Qashqai has additional safety features compared to the X-Trail, including front and rear head airbags and active braking. In terms of handling, it also includes front and rear parking sensors. 4. The Qashqai comes with a roof rack, which the X-Trail does not have. 5. The seven-seat X-Trail offers rear seat fore/aft adjustment and backrest adjustment. 6. The Qashqai has a 9-inch central control screen, while the X-Trail has a 7-inch one. 7. The Qashqai uses LED for both high and low beams, whereas the X-Trail uses halogen lights. 8. The Qashqai has heated rearview mirrors, which the X-Trail lacks. However, the X-Trail features power-folding rearview mirrors, which the Qashqai does not have.

How to Adjust Headlights?

Here are the steps to adjust headlights: 1. Turn on the high beams and stand in front of the headlights with your feet as close to the headlights as possible. Observe where the high beams hit your feet, locate the hotspot (the brightest spot of light projected by the headlight), and remember its position. 2. Then move straight to a wall (without deviating) and mark the hotspot position on the wall based on where it was on your feet. 3. Use a screwdriver to rotate the adjustment gear of the headlight, ensuring the hotspot aligns with the mark you made on the wall (the vertical deviation should not exceed 10 cm). 4. You can slightly raise the hotspot (generally no more than 5 cm higher). The reason is simple: an unloaded car sits higher, but when passengers are added, the car will lower slightly. Raising the hotspot slightly allows for this adjustment. 5. Adjusting vertically will show obvious movement of the hotspot. If adjusting horizontally, the hotspot movement is less noticeable. Don’t worry if you don’t see the hotspot moving sideways—keep turning the screwdriver until the hotspot aligns with your mark. 6. Once both headlight hotspots are aligned with the marks, stand in front of the car (a bit further away) and check whether the light beams projected by the headlights are straight forward.

What is the vehicle scrapping period?

Vehicles are divided into private cars and commercial vehicles, and their normal scrapping periods are as follows: Scrapping regulations for private cars: For 5-seat family cars and 7-seat SUVs, non-commercial small and mini vehicles have no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide the scrapping. In addition to the above vehicles, small and mini non-commercial passenger cars, large non-commercial cars, and wheeled special machinery vehicles also have no usage period limit. Scrapping regulations for common commercial vehicles: Small and mini taxi passenger vehicles have a scrapping period of 8 years, medium-sized taxi passenger vehicles 10 years, and large taxi passenger vehicles 12 years. Public transport passenger vehicles have a scrapping period of 13 years, other small and mini commercial passenger vehicles 10 years, and large and medium-sized commercial passenger vehicles 15 years. Mini commercial trucks have a scrapping period of 8 years, light and large commercial trucks 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal should fill out one copy of the "Motor Vehicle Alteration, Transfer, Modification, Suspension, Scrapping Approval Application Form" and stamp the owner's seal; Apply at the registration acceptance counter. For vehicles that have reached the scrapping period, issue the "Vehicle Scrapping Notice". For vehicles that have not reached the scrapping period, after inspection and confirmation by the motor vehicle inspection counter that they meet the scrapping standards, issue the "Vehicle Scrapping Notice"; The owner chooses a qualified recycling company to deliver the vehicle for dismantling with the "Notice"; After checking the "Notice", the recycling company dismantles the vehicle and takes photos, requiring the engine to be separated from the vehicle, the engine block to be broken, and the frame (chassis) to be cut; The owner submits the "Alteration Form", "XX Province Renewal Vehicle Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and vehicle dismantling photos to the motor vehicle inspection counter for verification and signature. The license plates and certificates are recycled, and the scrapping registration is processed according to regulations after approval.

What kind of engine oil is best for the Mazda3 Axela?

The original factory engine oil for the Mazda3 Axela is a fully synthetic 0W-20 oil from Japan. Alternatively, a semi-synthetic 5W-30 engine oil can also be used. More information about the Axela is as follows: 1. The Axela, equipped with Skyactiv Technology, uses an engine with Atkinson cycle functionality, which delays the closing of the throttle valve to ensure full combustion of the air-fuel mixture during ignition, resulting in an expansion ratio greater than the compression ratio. The Atkinson cycle is the most fuel-efficient type of engine, and to maintain its advantages, 0W-20 specification oil is used. 2. The Atkinson cycle is the most fuel-efficient type of engine, and to preserve its benefits, it is natural to use 0W-20 specification engine oil. Changan Mazda provides the first free maintenance for Axela owners, which must be completed within 5,000 kilometers of driving. After that, the vehicle requires maintenance every 5,000 kilometers or 6 months.
