Haval H9 burns oil because the engine's ultra-high-speed rotation can easily cause the lubricating oil film to break, leading to poor lubrication and dry friction in rotating parts. The solution is: the oil must be filled according to the specifications. When the oil filling exceeds the midline, the mechanic should be asked to extract the excess oil. Additionally, the oil level should be observed the next day before driving as the standard. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant, English name: Engine-oil. With a density of approximately 0.91×10³ (kg/m³), it can lubricate and reduce wear, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is known as the "blood" of the car. 2. Composition: Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil, giving it new properties, and are an important part of lubricating oil.

After driving for many years, I also encountered the issue of oil burning in my Haval H9, which is quite annoying. Oil burning is usually caused by worn piston rings or aging valve seals leading to poor sealing, allowing oil to seep into the combustion chamber and deplete quickly. I recommend the first step is self-inspection: regularly check the oil dipstick to monitor the consumption rate. If it exceeds half a liter per thousand kilometers, you should be concerned. Next, visit a professional repair shop for diagnosis, which might involve checking the exhaust pipe for blue smoke or using a computer to test engine pressure. The solution is generally to disassemble the engine and replace the damaged parts, such as piston rings or seals, costing a few thousand yuan, but early repairs save money in the long run. Using full synthetic oil can reduce wear and avoid frequent hard acceleration. Safety first—don’t delay repairs, or you risk engine cylinder damage and greater losses. Just be more vigilant during routine maintenance.

I've driven a Haval H9 for several years and have summarized some experiences after experiencing oil burning. Possible causes include PCV valve failure or aging seals leading to abnormal oil consumption. Initial simple steps: check if the oil level drops quickly and try changing to new oil for a few weeks. If that doesn't work, take it to a shop for a comprehensive inspection where technicians will use tools to test for leaks or compression issues. Solutions include replacing parts or using repair additives as a temporary fix, but the latter is not a long-term solution. The cost can be significant, so choose a reputable shop. Regular driving should avoid heavy loads and high RPMs, and timely maintenance like changing oil and filters can prevent issues. Remind yourself not to skimp on quality to save money, as prolonged oil burning can affect performance and may lead to breakdowns. Addressing the issue promptly will make driving smoother.

How to Operate the Rearview Mirror Button?

Adjust the left and right positions so that the left edge of the mirror just cuts off the right ear of your reflection in the mirror. When adjusting the up and down positions, place the distant horizon in the center, and adjust the left and right positions so that the car body occupies 1/4 of the mirror's area. For the right rearview mirror, adjust the up and down positions to occupy about 2/3 of the mirror. Adjust the left and right positions so that the car body occupies 1/4 of the mirror's area.

What Are the Standard Dimensions of a Sedan?

Standard sedan dimensions are categorized into several levels. For family cars, the length typically ranges from 3800mm to 4300mm, width from 1600mm to 1800mm, and height from 1400mm to 1600mm. 1. Length: Length is the most influential parameter affecting a car's purpose, functionality, and ease of use. Therefore, vehicle classes are generally divided based on length. A longer body means more longitudinal usable space, which is obvious; however, an excessively long body can make turning and parking inconvenient. 2. Width: Width mainly affects passenger space and maneuverability. For passenger sedans, if three seats arranged side by side are required to provide a spacious feel (primarily sufficient shoulder room), the width generally needs to reach 1.8 meters. In recent years, due to increased safety requirements, the thickness of door panels has increased, leading to a general increase in vehicle width. 3. Height: Vehicle height directly impacts the center of gravity (handling) and interior space. Most sedans have a height below 1.5 meters, significantly lower than the natural sitting height of a human, primarily to lower the vehicle's center of gravity and ensure stability during high-speed turns to prevent rollovers. 4. Wheelbase: Once the vehicle length is determined, the wheelbase becomes the most critical factor affecting passenger space, as the majority of two-box and three-box sedans position passenger seats between the front and rear axles. A longer wheelbase increases longitudinal space for passengers, directly benefiting legroom, which significantly impacts ride comfort.

Why does the new battery lose power when accelerating?

Here are the reasons why the new battery loses power when accelerating: 1. High starting current: The current is about three times that of normal driving. The combined resistance of the wiring, internal resistance of the battery, and the controller's field-effect transistors, along with high-current discharge, causes significant voltage fluctuations. 2. Charging duration: Battery self-discharge. Some users do not ride their electric vehicles immediately after fully charging them, leaving the vehicle unused for several days without timely recharging. 3. Damp wiring: If the electric vehicle is frequently used in rainy or snowy weather, damp wiring could also be a possible reason.

What are the steps for starting a car for the first time?

First, check around the car for any obstacles and inspect the tire pressure. Ensure safety before opening the door and entering the vehicle. Next, check the dashboard. Then, from left to right, inspect the left rearview mirror, and of course, also glance at the dashboard to check the fuel level and whether the headlights are on. After that, fasten the seatbelt, turn on the left turn signal, press down the clutch, shift into first gear, release the handbrake, and then slowly release the clutch to start the car while ensuring safety.

What does new energy vehicle quota or regular quota mean?

New energy vehicle quota refers to the eligibility to purchase new energy vehicles, while regular quota refers to the eligibility to purchase either fuel-powered vehicles or new energy vehicles. Regular quota has broader applicability: Entities and individuals holding regular quotas can purchase both conventional fuel-powered vehicles and new energy vehicles. However, those holding new energy vehicle quotas can only purchase new energy vehicles. Scope of new energy vehicles: New energy vehicle models eligible for purchase under the new energy quota are listed in the catalog issued by the Ministry of Industry and Information Technology of China. Currently, this includes only pure electric vehicles and plug-in hybrid electric vehicles. Some cities also allow the purchase of range-extended electric vehicles.

What are the techniques for reverse parking in an underground garage?

First, determine if the parking space is 'qualified'. When the front wheels pass the parking space, start turning the steering wheel to make the car move in the direction away from the parking space. Utilize the available width of the passage to tilt the car's position as much as possible. This allows the driver to observe the rear danger points of the vehicle through the rearview mirror. When a 'gap' between your car and the vehicles on both sides is visible in the right rearview mirror, you can adjust the steering wheel to modify the car's reversing trajectory and try to straighten it for parking.
