What does the LIM button in a car mean?

The LIM button in a car stands for the speed limit function. Pressing this button when the vehicle is stationary will activate the speed limit function. Below are specific details about the speed limit function: 1. Overview of the speed limit function: The speed limit system was first introduced as a standard feature in European-spec F10 models. This system can limit the vehicle speed between 30-230 km/h. When the speed is below the set limit, the vehicle can operate normally. Similar to traditional cruise control systems, the speed limit system uses the engine control system and automatic transmission control system to regulate speed by reducing the torque output requested by the driver. 2. Exceeding the speed limit: If the speed exceeds the set limit, the system will issue a warning. When reaching or exceeding the set speed limit during downhill driving, the active braking mode will not be engaged. If a speed limit lower than the current speed is set during driving, the vehicle will coast until the speed drops below the set limit.

What are the disadvantages of hybrid cars?

Hybrid cars have the following disadvantages: 1. High cost: The new car price is expensive, resulting in high purchase costs, and the fuel savings are largely offset by the higher initial price; replacing the battery after it ages requires a significant expense, increasing the cost of ownership. 2. Higher failure rate: The dual-drive system increases the vehicle's failure rate, adding another ownership expense. 3. Low resale value: The resale value decreases over time because potential buyers must first consider the cost of battery replacement. Below is related information: 1. Power source: Hybrid electric vehicles use a traditional internal combustion engine (diesel or gasoline) and an electric motor as power sources. Some engines are modified to use alternative fuels such as compressed natural gas, propane, and ethanol. 2. Electric power system: The electric power system in hybrid vehicles includes highly efficient and reinforced electric motors, generators, and batteries. The batteries used include lead-acid, nickel-metal hydride, and lithium-ion batteries, with potential future use of hydrogen fuel cells.

Why Use Turbocharging?

Adding turbocharging to a car can effectively enhance the power of small-displacement vehicles without increasing the engine speed, while also boosting engine power. This avoids the high fuel consumption associated with large-displacement vehicles, offering outstanding economic benefits and mature technology. Additionally, it provides car manufacturers with considerable profits, as turbocharged vehicles are more expensive to maintain and service compared to naturally aspirated (non-turbocharged) vehicles. Below is an introduction to turbocharging: 1. Turbocharged engines have outstanding advantages, consuming less fuel and producing fewer tailpipe emissions than naturally aspirated engines of the same power output, which is crucial in today's environmentally conscious era. 2. Turbochargers operate at extremely high speeds and generate much higher pressure than mechanical superchargers. They utilize exhaust gases to drive a turbine in the exhaust pipe, which in turn spins a compressor in the intake pipe, achieving indirect pressurization without consuming engine power. 3. However, due to the inertia of the turbine and the significant resistance of the intermediate bearings, the turbine speed cannot increase immediately when exhaust gases suddenly surge, resulting in turbo lag.

Can the Vehicle Charge While Idling?

Vehicles can charge while idling, but the charging efficiency is not optimal. After the engine starts, the electricity generated by the alternator is primarily used to power the vehicle's own electrical systems, leaving little surplus current. The current only becomes sufficient when the engine speed exceeds 2000 RPM, so idling charging is not recommended. Below are specific details: 1. Modern vehicles use alternators for charging. The battery's power is mainly used to start the vehicle, which consumes a significant amount of energy. However, once the engine is running, the battery is no longer drained. 2. The power consumed during startup is replenished through the vehicle's charging circuit. Charging can occur while idling, but the charging current is relatively small. 3. Typically, household car batteries have a capacity between 54-60Ah. Battery capacity indicates the amount of power the battery can discharge under specific conditions (discharge rate, temperature, cutoff voltage, etc.). 4. The capacity of car batteries is usually measured in Ah. For example, a 60Ah battery can continuously discharge at 1A for 60 hours.

How to Solve the Sunroof Rattle on Bumpy Roads?

Sunroof rattling on bumpy roads is caused by vibrations between the sunroof and its sliding rails. It is recommended to avoid fully opening the sunroof on extremely rough roads, as excessive vibration between the sunroof and rails may lead to deformation of related components or even damage the motor. Owners are advised to visit a repair shop or 4S dealership to apply specialized sunroof lubricant. Below are some important precautions for sunroof usage: 1. When opening the sunroof, check for any obstacles on the roof that might hinder its upward or backward movement, as overload could burn out the motor or accidentally scratch the glass surface. 2. Always operate the sunroof correctly when opening or closing it, as improper handling may cause excessive current in the motor, leading to burnout. 3. Avoid opening the sunroof when driving on extremely bumpy roads, as severe vibration between the sunroof and rails may deform components, potentially causing damage during operation. 4. Do not direct high-pressure water jets at the sunroof's sealing strips during car washing, as this may deform the seals and cause leaks.

Why Does Subaru Use CVT Transmissions?

Subaru's transmission is quite different from other vehicles, with the transfer case and transmission being integrated as a single unit. This means that each update or redesign requires comprehensive development, which takes considerable time and presents significant technical challenges. In contrast, using a CVT transmission reduces these difficulties to some extent. Below are the advantages of CVT transmissions: Optimal Power Delivery: A CVT transmission allows the car to always be in the correct "gear." Unlike automatic or manual transmissions, programming a CVT keeps the engine's RPM within the optimal power range rather than delivering a sudden burst of power when the driver accelerates. In certain scenarios, especially when overtaking, a CVT transmission can provide the most direct performance. Superior Fuel Efficiency: CVT transmissions are more efficient than manual, dual-clutch, or automatic transmissions—at least in terms of fuel economy. They enable the car to operate at the most economical RPM at all times. When cruising at a steady speed, a car equipped with a CVT transmission can maintain very low RPMs, significantly reducing fuel consumption.
