The difference between independent suspension and non-independent suspension: The biggest difference between independent suspension and non-independent suspension lies in whether there is a connection in the middle. Independent suspension has no connection in the middle, while non-independent suspension does. This is also why independent suspension offers better comfort and handling compared to non-independent suspension. Suspension is an important component of a car's chassis, used to connect the wheels to the body. Without suspension, a car cannot operate normally. There are many types of suspension structures. Common independent suspensions in cars include MacPherson strut, multi-link suspension, double-wishbone suspension, double transverse arm suspension, and double ball joint suspension. Non-independent suspensions in cars include torsion beam suspension and solid axle suspension. MacPherson strut is the most common independent suspension. Most cars use MacPherson strut for their front suspension. This type of suspension is the simplest in structure, the most widely used, and the lowest in cost among independent suspensions. Double-wishbone suspension is a relatively high-end independent suspension, consisting of upper and lower wishbones. Multi-link suspension and double transverse arm suspension are actually improved versions based on double-wishbone suspension. Multi-link suspension is a more complex version of double-wishbone suspension, where the two wishbones are replaced by separate links. Double transverse arm suspension is a simplified version of double-wishbone suspension, where the two wishbones are replaced by two links. Types of independent suspension include: MacPherson strut, double-wishbone suspension, multi-link suspension, double transverse arm suspension, and double ball joint suspension. In cars with independent suspension, there is no connection between the two wheels on the same axle, meaning no interference between them. Independent suspension provides better comfort and handling. Double ball joint suspension is a more complex version of MacPherson strut, where the L-shaped control arm is replaced by two links, creating two connection points between the suspension and the steering knuckle. Double ball joint suspension improves steering precision and enhances handling. Multi-link suspension is a more complex version of double-wishbone independent suspension, where the two wishbones are replaced by four links. Double transverse arm suspension is a simplified version of double-wishbone suspension, where the two wishbones are replaced by two links. MacPherson strut is the most widely used suspension. Most cars use MacPherson strut for their front suspension due to its simple structure, low cost, and compact size.

Hey, I just drove a car with independent suspension, and the difference is huge! Simply put, independent suspension is like each wheel having its own 'leg.' When hitting bumps, one wheel's movement doesn't affect the other, making the ride much smoother, especially with strong grip during high-speed turns. Non-independent suspension, on the other hand, ties the left and right wheels to a single axle—when one wheel jumps, the other wobbles too, making rear-seat passengers feel every bump and vibration. Independent suspension has a more complex structure and higher maintenance costs, but offers better ride comfort; non-independent suspension is sturdy and durable, commonly used in older pickups, saving a lot on costs. For daily city driving in traffic, independent suspension is more comfortable and worth the extra money.

What Does Range Mean?

Range refers to the maximum distance a vehicle can travel on a full tank of fuel at an economical speed. This is an estimated figure provided by the vehicle's instruments based on certain standards and calculations. For example, if a 50-liter fuel tank allows the car to travel 600 km, this distance is considered the range. Range can also be referred to as endurance, indicating the total distance a vehicle (such as a car or ship) can travel continuously with a substantial fuel reserve. For new energy vehicles, the maximum battery-supported range refers to the highest distance the vehicle can travel in pure electric mode, relying solely on the battery's charge. For hybrid vehicles, the maximum battery-supported range is typically shorter, usually not exceeding 10 kilometers.

What is the Vehicle Green Book?

The Vehicle Green Book is the motor vehicle registration certificate. The registration certificate is not a legal proof of vehicle ownership but rather an administrative document permitting the vehicle to be driven on the road. The motor vehicle registration certificate serves as the essential proof of vehicle ownership, kept by the vehicle owner and not carried with the vehicle. It is required to be presented for any vehicle registration procedures such as transferring registration or ownership changes, and it records relevant details about the vehicle, functioning similarly to a vehicle's household registration booklet. According to current motor vehicle registration regulations and related provisions, the registration conducted by public security authorities is for permitting or prohibiting road use, not for confirming vehicle ownership. For the purposes of traffic management, vehicle management offices under public security authorities confirm the vehicle owner based on documents such as the purchase invoice or legal judgments, rulings, and mediation documents from the court when issuing vehicle license plates. If the motor vehicle registration certificate is lost, missing, or damaged, the vehicle owner must apply for a replacement or reissuance at the local vehicle management office where the vehicle is registered.

What to do with ETC when changing cars?

When changing cars, the ETC needs to be canceled. The car owner should bring their ID card, vehicle registration certificate, and bank agreement to an ETC service point for installation and activation. Before changing cars, the owner needs to bring their ID card, vehicle registration certificate, ETC card, and OBU device to an ETC customer service center for removal. Then, with the removal receipt issued by the ETC customer service center, they can terminate the contract at the contracted bank. ETC dedicated lanes are for vehicles equipped with ETC onboard units, using electronic toll collection. ETC utilizes dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station. It employs computer networking technology to conduct background settlement processing with the bank, achieving the purpose of vehicles passing through toll stations without stopping to pay toll fees.

What are the symptoms and causes of a misfiring cylinder?

The symptoms of a misfiring cylinder are: There is an issue with the fuel injector of a certain cylinder, leading to fuel supply problems in that cylinder. The causes of a misfiring cylinder are: The spark plug, ignition coil, and high-voltage wire—these three components can all affect the high-voltage electricity required for ignition. Another less common cause is cylinder leakage. When the engine cylinder valves do not seal properly, resulting in insufficient cylinder compression, misfiring can also occur. A damaged spark plug will not function, but the fuel injector continues to operate. The unburned fuel injected into the cylinder will cause the engine's exhaust emissions to exceed standards significantly. At this point, the vehicle's onboard computer will trigger an alert, and various sensors may not function properly. The information displayed on the dashboard is a direct reflection of the vehicle's condition. When certain engine systems malfunction, the dashboard's warning lights will illuminate, prompting the driver to inspect the vehicle as soon as possible.

What are the differences between China 5 and China 6 vehicle emission standards?

The differences between China 5 and China 6 emission standards are as follows: Different emission standards: China 6 standards are more than 30% stricter than China 5. Excluding the influence of working conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbons and non-methane hydrocarbons emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different implementation times: The China 5 standard was implemented nationwide on January 1, 2017. China 6 has been implemented since July 1, 2019. Different principles: During the China 5 phase, diesel and gasoline vehicles had different emission standards, but China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different issuing authorities: The China 5 standard was issued by the Ministry of Environmental Protection. The China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection and Quarantine. Different letter representations: China 5 is represented by "V"; China 6 is represented by "VI". Different monitoring requirements for plug-in hybrid electric vehicles: Compared to China 5, China 6 has improved monitoring requirements for plug-in hybrid electric vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulations. China 5 standard limits are as follows: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM fine particles per kilometer driven. China 6 has two standards: China 6a and China 6b. The details are as follows: China 6a standard limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM fine particles per kilometer driven. China 6b standard limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM fine particles per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles are not currently restricted in normal use, their resale value is significantly impacted. For truck owners, if they purchase a truck on loan for hauling goods, the depreciation of the vehicle after paying off the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China 6 vehicles, which have a longer service life and more road rights, are more advantageous.

What does 3 differential locks mean?

3 differential locks refer to: 1. Differential lock 1 makes the front and rear axles rotate at the same speed, suitable for situations where there is gravel or slight bumps causing the front or rear wheels to slip; 2. Differential lock 2 makes the two rear wheels rotate at the same speed as the front axle, used when encountering larger rocks or more severe bumps on the road; 3. Differential lock 3 ensures all wheels have the same power, used for more complex road conditions or when all wheels on the same side lose traction. Differential locks can be considered as differentials with automatic locking functions. Common types of differential locks include friction plate and cone types, and their effectiveness is determined by the locking coefficient. The locking coefficient refers to the maximum possible multiple of torque difference between the two half-shafts, and the locking effect increases with the input torque and torque difference.
