Is There a Difference Between Gear Oil and Engine Oil?

Gear oil and engine oil are different, mainly reflected in the following aspects: 1. Different working environments: Gear oil is primarily used in manual transmissions, reducers, and differentials, while engine oil is mainly used in car engines. Since gear meshing involves line contact, gear oil must have extremely high viscosity to form an oil film at the gear meshing points. In contrast, engine lubrication involves mostly surface contact, without the extreme high pressure generated during gear meshing, so its viscosity requirements are relatively lower. 2. Different emphases: Gear oil focuses on protecting gears under high temperatures, while engine oil emphasizes its fluidity at low temperatures. Additionally, gear oil is strongly alkaline, whereas engine oil is weakly alkaline. 3. Engine oil and gear oil must never be mixed, as this can easily prevent machinery from achieving optimal lubrication, leading to damage.

The Difference Between EV and DM

DM and EV mainly differ in three aspects: power source, appearance, and performance. Below is a detailed introduction to the differences between EV and DM: 1. Power Source: EV is essentially a pure electric vehicle, while DM is a plug-in hybrid electric vehicle. EV can only be replenished by charging, whereas DM can switch between fuel and electric modes. 2. Appearance: In terms of front grille design, the EV series adopts a closed grille, while the DM series features a horizontal bar grille. 3. Performance: The EV series innovatively uses lithium nickel manganese cobalt oxide batteries, with ultra-large battery capacity and ultra-high battery density, achieving a comprehensive range of 420km, excelling in mileage. The DM series, as a plug-in hybrid, can accelerate from 0 to 100km/h in just 5.9 seconds. Additionally, the DM series incorporates a new BSG motor in the third-generation hybrid platform, and the driving mode that combines fuel and electricity can minimize fuel consumption to the greatest extent.

What are the advantages of a body-on-frame structure?

Body strength is high, as the steel frame provides strong body rigidity, which also helps improve safety. More relevant information is as follows: 1. Vehicles with a body-on-frame structure have a rigid frame, also known as a chassis frame. In a body-on-frame structure, components such as the engine, part of the transmission system, and the body are mounted on the frame via suspension systems, and the frame is connected to the wheels through front and rear suspension systems. 2. The body-on-frame structure is relatively heavy, has a large mass, and is tall, generally used in trucks, buses, and off-road vehicles. Some high-end sedans also use this structure because it offers better stability and safety. Simply put, the suspension is not directly connected to the body but to the frame, and the body is then mounted on top of the frame.

What is the Difference Between Metallic Paint and Non-Metallic Paint for Cars?

The differences between metallic paint and non-metallic paint for cars are: 1. Different composition: Metallic paint is a two-component ambient temperature curing coating, where Component A consists of resin base, high-quality pigments and fillers, and additives, while Component B is the curing agent. Non-metallic paint is composed of resin, pigments, additives, fillers, curing agents, and solvents. 2. Different performance: Metallic paint has improved wear resistance and is less prone to scratches; non-metallic paint is more susceptible to scratches when parked by the roadside or subjected to external forces. 3. Different hardness: Metallic paint contains metal powder, giving it metallic components and a harder surface that is less prone to scratches; regular paint, which lacks metal powder, has a softer surface that is more likely to peel when hit by flying stones on the road during high-speed driving.

What Are the Hazards of Not Changing Transmission Fluid?

The hazards of not changing transmission fluid are as follows: 1. Prolonged failure to change the transmission fluid can lead to abnormal wear and severe deterioration of the fluid. 2. Under high-speed and high-temperature conditions, old transmission fluid can deteriorate and evaporate, accelerating the wear of mechanical components. In severe cases, it may damage internal transmission parts and shorten the vehicle's lifespan. 3. Over time, the transmission fluid can become granular, clogging the oil passages and damaging the valve body, which directly affects system oil pressure and power transmission. This can result in delayed responses and gear-shifting shocks. Generally, the replacement interval for transmission fluid follows the same calculation method as the vehicle's maintenance cycle, based on mileage or usage time. If the vehicle's manual specifies these indicators, the earlier one should be followed. If the manual does not provide such indicators or does not clearly state the fluid change interval, it is typically recommended to replace the transmission fluid every 50,000 to 80,000 kilometers.

What does TC mean when displayed on the car dashboard?

The display of TC on the car dashboard indicates that the vehicle's traction control system is active. More relevant information is as follows: 1. TC stands for Traction Control System, designed to enhance the stability of the vehicle while in motion, especially for rear-wheel-drive cars. 2. The Traction Control System primarily relies on sensors from the Anti-lock Braking System (ABS), processing and responding to the information received from these sensors. When it detects that the speed of the driven wheels is lower than that of the driving wheels, it makes detailed adjustments to the vehicle's ignition timing, valve opening, throttle, etc., to prevent the car from skidding. 3. The Traction Control System works in conjunction with the Anti-lock Braking System, playing a significant role in vehicle safety and driving stability. 4. This system cannot be turned off during use, and it is not recommended to do so, as the absence of these electronic control systems would significantly increase the likelihood of the vehicle losing control, leading to uncontrollable consequences. With the continuous improvement in people's safety awareness, the various safety configurations in vehicles will become increasingly sophisticated, bringing us closer to the era of intelligent automobiles.
