What Causes the Electronic Power Steering Wheel to Feel Heavy?

The reasons why the electronic power steering wheel feels heavy: 1. When the car's steering gear lacks lubrication, symptoms such as steering stiffness and a heavier steering wheel may occur. It is necessary to add lubricating oil, and in some cases, replace the power steering fluid; 2. When the tire pressure of the car is too low, the contact area between the tire and the ground increases, resulting in greater resistance during driving, making the steering wheel feel heavier. It is essential to inflate the tires promptly; 3. If the battery has been undercharged for a long time, the steering wheel will not receive assistance from the motor. In this case, the battery needs to be recharged; 4. If the car's electronic power assist fails, the steering wheel will become heavier, requiring inspection and repair at a 4S shop.

What are the reasons for the loud noise inside the Haval H2?

Haval H2's loud interior noise is due to engine damage, which can be categorized into two types: cold engine abnormal noise and hot engine abnormal noise. Cold engine abnormal noise refers to the unusual sounds emitted from the engine compartment when the car is parked, which automatically disappear after the car is warmed up. This happens because when the car is parked for a long time, the lubricating oil basically flows back to the oil pan. During a cold start, the oil pump cannot immediately establish oil pressure, and the oil film between components, especially the valves inside the cylinder head, cannot be lubricated during a cold start. Both hydraulic lifters and mechanical rocker arms will have a certain valve clearance, or the timing chain with insufficient oil pressure cannot work properly, resulting in a clicking sound. There are many reasons for hot engine abnormal noise, generally due to damaged or faulty car components. For example, the engine oil viscosity is too high, there is carbon buildup in the engine cylinders, or there is valve leakage, which require timely repairs.

How many years does it generally take for a vehicle to be scrapped?

Generally, vehicles are scrapped after 15 years, but currently, the scrapping of private cars has shifted from being based on years to mileage, with a maximum mileage of 600,000 kilometers. Starting from May 1, 2013, old vehicles were phased out according to new regulations, which eliminated the scrapping age limit for private cars, setting a maximum mileage of 600,000 kilometers. The regulations stipulate that small and micro non-operational passenger cars, large non-operational vehicles, and wheeled special-purpose machinery vehicles have no usage age limit. The new retirement age regulations for household vehicles removed the driving age limit for non-operational cars as officially released by the Ministry of Commerce in the "Mandatory Scrapping Standards for Motor Vehicles," limiting private cars to 600,000 kilometers. This mileage-based restriction, instead of a year-based one, significantly improves vehicle utilization. Data: The extension of the retirement age for household vehicles imposes higher requirements on the safety and technical inspections of vehicles. Under the new policy, private cars require two annual inspections starting from the 15th year after registration, and those over 20 years old require four annual inspections starting from the 21st year. During annual inspections, strict regulations apply to older vehicles. When inspecting the power of private cars, the chassis output power must not be less than 60% of the engine's rated power or 65% of the maximum net power. Additionally, according to the new standards, vehicles that fail to meet safety standards and do not comply with environmental standards within one inspection cycle will be forcibly scrapped. The power inspection project will also replace the existing fuel consumption project, phasing out vehicles with poor performance indicators. Therefore, while the usage age of vehicles has been relaxed, the elimination of older vehicles has been strengthened, especially with stricter control over environmental standards.

What are the differences between the GL8 ES and the regular version?

The differences between the GL8 ES and the regular version include the powertrain, trunk volume, suspension, and exterior design. Different powertrains: The regular GL8 Business Travel offers two engine options, a 2.5L and a 2.0T, while the GL8 ES only comes with a 2.0T engine. Trunk volume: The regular GL8 Business Travel has a trunk volume of 475-1605L, while the GL8 ES offers 521-1650L. Different suspensions: The regular GL8 uses a torsion beam non-independent suspension (solid axle), whereas the GL8 ES is equipped with a multi-link independent suspension. Different exterior designs: The regular GL8 only adds a winged chrome trim to the Buick logo on the front face of the 'Fathead Fish' GL8, without changing the overall shape. In contrast, the GL8 ES features a completely new upgrade in both exterior and interior design.

Why does the engine only reach 4000 RPM when the throttle is fully pressed in neutral?

When the throttle is fully pressed in neutral and the engine only reaches 4000 RPM, it's because the engine has a protection program that limits the RPM. Therefore, when the throttle is pressed in neutral, the engine speed generally won't exceed 4000 RPM. It is not recommended to press the throttle in neutral as it can cause certain damage to the engine. When the engine has just started and hasn't reached its normal operating temperature, the oil film hasn't fully covered the components. Pressing the throttle at this time can lead to abnormal wear on the engine. Even when the engine reaches its normal operating temperature, forcefully pressing the throttle can still cause damage. In neutral, when the engine load is low, pressing the throttle can cause the RPM to rise too quickly, resulting in a sudden increase in pressure on internal components. When the RPM rises rapidly, lubrication at various friction points may not keep up. To protect the engine, the RPM is limited when the engine is in neutral.
