When the engine RPM is high but the speed cannot increase, it must be an issue with the clutch or transmission, as the power generated by the engine is not being transferred to the wheels. Engine Characteristics 1. The engine valve drive mechanism adopts a hydraulic support roller rocker arm structure. Compared to the commonly used hydraulic lifter valve drive mechanism in modern gasoline engines, this innovative valve drive mechanism has the advantage of relatively lower friction torque, thus requiring less driving force. This effectively reduces engine power consumption and lowers fuel consumption. 2. To significantly reduce the overall vehicle weight, the 1.4-liter gasoline engine uses an aluminum alloy cylinder block, achieving a notable lightweight effect.

What is the first maintenance mileage for the 2021 Buick Excelle?

The first maintenance for the vehicle is at 5,000 kilometers or three months. Below are the specific details: Introduction: The first maintenance for the Buick Excelle is at 5,000 kilometers or 6 months, whichever comes first. For the first maintenance, only an oil change and oil filter replacement are necessary. As long as the vehicle is functioning normally, any additional paid services recommended by customer service can be declined. Precautions: When the vehicle reaches the specified mileage or time, maintenance should be performed promptly. Additionally, the two complimentary oil and oil filter changes provided for the Excelle are valid for 3 years or 100,000 kilometers. The period from when the new car is driven until the first maintenance is referred to as the break-in period. During this period, since the gears of the engine, transmission, etc., have not yet fully broken in smoothly, the driver should generally avoid driving too fast—absolutely no more than 100 km/h, and preferably not exceeding 80 km/h. During the first maintenance, it is essential to check tire pressure, perform wheel alignment and balancing, and inspect the safety systems, all of which are critical and should not be overlooked.

Does a non-functioning front fog light affect the annual inspection?
