What Causes the Steering Noise in BYD Tang?

BYD Tang steering noise may be caused by lack of oil in the shock absorber's plane bearing, loose stabilizer bar bushings, or steering gear failure. Lack of oil in the shock absorber's plane bearing: Open the hood and listen to see if the sound is coming from the top of the shock absorber. If the noise is from the plane bearing, you can apply some grease to the plane bearing. Loose stabilizer bar bushings: Check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings will not only cause noise when turning the steering wheel but also make sounds when driving on uneven roads. Loose stabilizer bar bushings can be fixed by adding shims. Steering gear failure: If you hear a "clicking" noise when turning the steering wheel, it may be due to excessive clearance in the steering gear's matching gears, which requires replacing the steering gear.

Where is the engine serial number located on a BMW 320i?

BMW 320i engine serial number is located on the nameplate on the left side of the engine compartment wall. More information is as follows: Engine number cannot be altered: The engine number cannot be arbitrarily changed or replaced. If the engine number or vehicle identification number becomes illegible or damaged due to wear, corrosion, accidents, etc., an application for record filing can be made to the vehicle management office at the registration location. Composition of the engine serial number: The digits on the engine serial number represent the engine number, which consists of 4 parts: the prefix includes product series code, generation symbol, and regional/enterprise code; the middle section consists of cylinder count symbol, cylinder arrangement symbol, stroke symbol and bore diameter symbol; the rear section includes structural feature symbol and usage feature symbol; the suffix is a distinguishing symbol - when differentiation is required for improved versions within the same series, the manufacturer selects appropriate symbols, with the rear section and suffix potentially separated by "-".

What causes the abnormal noise in the steering oil when starting the Haval F7 cold?

Check the stabilizer bar ball joint, commonly known as the vertical tie rod, and the stabilizer bar rubber bushing. These two components are likely to cause this issue. Below is some relevant information: 1. The 2020 Haval F7 retains the space technology aesthetic design language for its exterior, with the grille upgraded to a shield-style design. The aggressive hexagonal grille with a matte frame and honeycomb mesh gives the front fascia a very clean design language. The floating spoiler features a novel and unique design while also reducing wind resistance and saving fuel. 2. The 2020 Haval F7 adds L2-level autonomous driving and semi-automatic parking functions, enabling interaction between the car and the driver to assist in completing the driving journey more conveniently, safely, and quickly.

How many kilometers for the second maintenance of a new car?

The first maintenance is at 5,000 kilometers or 3 months, and the second maintenance is at 10,000 kilometers or 9 months. Whichever comes first, either the mileage or the time, will be the criterion. Here are some relevant information: 1. Car maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. 2. For the second maintenance of a car, there is no need for other replacements or cleaning, such as engine cleaning. It is too early to perform these items during the second maintenance, which would be a waste of both money and time. Other inspection items, such as checking the coolant, brake fluid, tire pressure, etc., are generally free of charge. Here is a reminder to all car owners: before the second maintenance, be sure to carefully review the maintenance list, and it is recommended not to perform unnecessary items.

What does 95-octane gasoline mean?

95-octane gasoline refers to standard gasoline with an anti-knock performance equivalent to a mixture of 95% isooctane and 5% n-heptane. The higher the gasoline octane number, the stronger its anti-knock performance. Standard gasoline is composed of isooctane and n-heptane. The implementation of this standard will help improve the overall quality of automotive gasoline in China, reduce vehicle emissions, and decrease nitrogen oxide and particulate emissions from new vehicles by 25% and 80%, respectively. For in-use vehicles, emissions can be reduced by 10% to 15% overall. This standard is significant for environmental protection and improving air quality. Relevant information about gasoline is as follows: Introduction: Gasoline is a volatile, flammable hydrocarbon mixture liquid distilled and cracked from petroleum, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. Key characteristics: The important properties of gasoline include volatility, stability, anti-knock performance, corrosiveness, and cleanliness. Standard: On December 18, 2013, the mandatory national standard for Phase V automotive gasoline was released. 95-octane gasoline complies with this standard. The standard took effect upon release, and Phase V automotive gasoline was supplied nationwide starting January 1, 2018. High-compression engines should use high-octane gasoline. Using low-octane gasoline in high-compression engines can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced power. However, high-compression engines can also use low-octane gasoline. The choice of gasoline octane should not be blindly based on compression ratio but should follow the manufacturer's recommendations. In addition to checking the appropriate gasoline octane in the vehicle manual, you can also find it on the fuel tank cap. Typically, the gasoline octane can also be determined based on the engine's compression ratio. Vehicles with a compression ratio between 8.6 and 9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0 and 11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the use of new technologies, the choice of gasoline octane cannot be solely based on compression ratio. High-compression engines can be tuned to use low-octane gasoline because factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Occasionally using the wrong gasoline octane is not a problem as long as you switch back to the correct octane afterward. However, long-term use of the wrong gasoline octane can have the following effects: Using high-octane gasoline in a vehicle designed for low-octane gasoline will not cause damage, but the increased octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using low-octane gasoline in a vehicle designed for high-octane gasoline can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unstable. If the knocking is mild, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

Is the Geely Boyue's Eco Mode Fuel-Efficient?

Geely Boyue's Eco mode is fuel-efficient. Here are the relevant details: 1. The Boyue offers three driving modes: Sport mode, Normal mode, and ECO mode (Economy mode). Official data indicates that the ECO mode is slightly more fuel-efficient than the other two. 2. The Boyue's ECO mode can save fuel to some extent. According to data from Geely Boyue's official website, the Economy mode can improve fuel efficiency by 3%~8%. Many Boyue owners habitually use ECO mode while driving because in this mode, all forward gears automatically upshift earlier and downshift later, effectively reducing engine RPM and achieving better fuel economy. 3. Since ECO mode forces the transmission to shift at lower RPMs, prolonged use in low-speed traffic congestion may increase carbon deposits in the engine and throttle body, doing more harm than good. Therefore, it's recommended to avoid using ECO mode in heavy traffic. 4. How to use ECO mode: When in P/R/N/D gear, press the ECO switch, and the indicator light will illuminate, indicating entry into Economy mode.
