Why does the new Magotan have slight idle vibration?

The reasons for slight idle vibration in the new Magotan are as follows: Excessive carbon deposits: Severe carbon buildup in the engine cylinders can cause spark plug blockage and valve blockage, directly leading to vehicle vibration during idle. If the car's acceleration performance has significantly deteriorated and the vibration persists, an engine cylinder cleaning should be considered. Fuel supply system malfunction: Unstable fuel pressure can easily cause fluctuations in the concentration of the air-fuel mixture, not only resulting in vibration but also causing unstable idle. First, consider replacing the fuel filter, as prolonged use may lead to filter clogging. Then, check the fuel pressure bypassing the fuel filter. If abnormal, it may indicate a fuel pump issue. Aging engine mounts: Aging engine mounts are also a very common cause of vibration. If the engine vibration becomes increasingly severe but the power output does not weaken accordingly, it may be time to check the engine mounts.

Why does the Geely Boyue engine shake when the air conditioning is turned on?

The most common reason for the Geely Boyue engine shaking when the air conditioning is turned on is a dirty throttle body, which affects the engine. When the air conditioning is turned on in this condition, it increases the engine idle load, resulting in steering wheel vibration. Therefore, cleaning the throttle body can prevent this issue. The compressor increases the engine load: When the air conditioning is activated, the compressor also starts working, and since the compressor is driven by the engine, it increases the engine load. This increased load means the throttle opening needs to widen to allow more air intake. Obstructed air intake reduces engine pressure: After turning on the air conditioning, the engine load suddenly increases, and the throttle opening expands. At this point, the drawback of a dirty throttle body becomes more pronounced. The throttle may stick or fail to open to the proper position, obstructing air intake and reducing engine power, ultimately leading to engine shaking.

What does the BMW 740's integral active steering modification mean?

Integral Active Steering refers to BMW's integral four-wheel steering system. It is completely different from the active steering system. By using an electric motor to adjust the rear wheel angle, it achieves smooth and stable cornering at both high and low speeds. Currently, it is only available on high-end models: the BMW 7 Series has a steering angle of 3 degrees, and the 5 Series GT also features it. Superimposed Steering System: In the Integral Active Steering system, a hydraulic or electric servo steering system is first required as the foundation. In the steering transmission route, the steering column between the steering wheel and the servo steering gear is disconnected. At the disconnection point, a steering angle actuator is added as an electronic adjustment device, consisting of an electric motor and a reduction mechanism, which increases or decreases the steering angle based on the vehicle's state and the driver's input. Due to this superimposed steering angle, this system is also called a Superimposed Steering System. Steering Gear Function: The function of the steering gear can directly act on the wheels and still satisfactorily return to pure mechanical capability with the help of the actuator, independent of the basic servo steering system. Therefore, the safety of its electronic adjustment chain is referred to as "fail-safe" or "fail-silent." The industrialization of the Active Steering-Cross Unit can be achieved in different ways.

After how many kilometers does the Nissan X-Trail need an oil change?

Nissan X-Trail oil changes are not directly related to mileage but depend on the type of oil used. Oil types and replacement frequency: Mineral oil: Change every 5,000 kilometers or 3 months; Semi-synthetic oil: Change every 7,500 kilometers or 6 months; Full synthetic oil: Change every 10,000 kilometers or 1 year; Cepsa oil: Change every 15,000 kilometers or 18 months. Oil change rules: The oil change interval is best determined according to the car maintenance manual recommendations or the oil manufacturer's recommended mileage for replacement.

What is the reason for black smoke from the Geely King Kong exhaust pipe with an overly rich air-fuel mixture?

Black smoke from the Geely King Kong exhaust pipe is due to incomplete combustion of the air-fuel mixture. Black smoke occurs because of incomplete combustion of the air-fuel mixture: When there is insufficient air intake and excessive fuel, the engine's combustion process becomes incomplete. Gasoline does not burn completely, forming a large amount of carbon particles under high temperatures, which results in black smoke being emitted. The exhaust pipe can emit smoke of different colors: When starting the car in winter, due to the low external temperature, water vapor produced after engine combustion turns into white smoke when emitted. If the car has a malfunction, blue smoke appears when engine oil enters the combustion chamber and participates in the combustion process.

Should I Top Up Engine Oil When the Oil Dipstick of Haval H2 is at the Lower Limit?

Haval H2 oil dipstick at the lower limit position requires topping up engine oil, as being at the lower limit indicates insufficient oil reserve. Function of the oil dipstick: To check the level of engine lubricating oil. Experienced drivers or repair personnel can perform engine maintenance by inspecting the oil dipstick, promptly identifying the causes of faults or accidents, and preventing further deterioration of issues. Proper use of the oil dipstick plays a crucial role in extending the engine's service life. Meaning of the dipstick scale: It measures the static height of the oil level, thereby reflecting whether the engine oil inventory is within a reasonable range.
