China VI in automotive standards refers to China 6. The China 6 emission standard imposes more stringent requirements compared to the China 5 emission standard, with stricter limits on pollutant emissions. The implementation of the China 6 emission standard will be carried out in two phases. Starting from July 1, 2020, all light-duty vehicles sold and registered must comply with the China 6a limit requirements. The second phase will begin on July 1, 2023, when all light-duty vehicles sold and registered must meet the China 6b limit requirements. Automotive emissions refer to harmful gases such as CO (carbon monoxide), HC plus NOx (hydrocarbons and nitrogen oxides), and PM (particulates, soot) released from exhaust gases, all of which are produced during the engine's combustion process.

What does turbocharging mean?

Turbocharging is a technology that utilizes the exhaust gases produced by internal combustion engine operation to drive an air compressor. Its working principle involves using the inertial impulse of the engine's exhaust gases to propel the turbine in the turbine chamber, which in turn drives the coaxial impeller. Through high-speed rotation, it forces more air into the intake manifold, thereby improving the engine's combustion efficiency. Turbocharging is divided into four types: mechanical supercharging, pressure wave supercharging, exhaust gas turbocharging, and compound supercharging. Its main function is to increase the engine's air intake, thereby enhancing the engine's power and torque, making the vehicle more powerful. It was initially used in sports cars or Formula racing cars.

What does SRC mean in a car?

SRC in a car refers to the audio source selection button, which is used to switch between CD, USB, or Bluetooth audio sources. It can also be used to change songs or switch between radio stations, functioning similarly to a remote control. This button is typically located on the multifunction steering wheel of a car. The detailed usage of this button can be found in the vehicle's manual. A multifunction steering wheel is designed with various control buttons on its sides or lower part to allow drivers to operate more conveniently. These controls may include audio system adjustments, air conditioning settings, hands-free calling, and in some cases, cruise control buttons are also integrated into the steering wheel.

Where is the rearview mirror heating switch located?

The rearview mirror heating control switch is located on: the electric rearview mirror adjustment combination switch; the air conditioning control panel. After pressing the button, the electric heating element behind the rearview mirror glass will quickly heat up to a fixed temperature within a few minutes, usually between 35 to 60 degrees Celsius. Warm air will emerge from both left and right rearview mirrors, and the fog will gradually disappear, thereby achieving the effect of heating the mirror and removing fog and frost. In cases of particularly heavy rain, its effectiveness may decrease and the effect may not be very noticeable. Although the car rearview mirror heating function is practical, it is limited in some vehicle models. For example, the rearview mirror heating is set to work only when the ambient temperature is below 15 degrees Celsius.

What is the VSC warning light?

VSC stands for the Toyota Vehicle Stability Control system warning light. When the driver operates improperly or encounters abnormal road conditions, such as sudden turns, acceleration, or braking, the vehicle can quickly sense these situations and take corresponding braking measures, while alerting the driver with a warning light. This enhances the vehicle's handling safety and driving convenience. The VSC system can actively regulate the engine throttle to adjust engine speed and control the driving force and braking force of each wheel, thereby correcting oversteer and understeer. If this system's warning light stays on, it is recommended to visit a 4S dealership for computer diagnostics and repairs.

What are the reasons for the engine oil pressure warning light to illuminate?

Reasons for the engine oil pressure warning light to illuminate: 1. Insufficient oil quantity reduces the oil pump's output or causes air intake preventing oil delivery, leading to decreased oil pressure; 2. Overheating engine thins the oil, causing excessive leakage through clearances and resulting in pressure drop; 3. Damaged oil pump components, excessive wear, or improper assembly causing excessive clearances, leading to pump failure or insufficient oil delivery; 4. Improper clearance between crankshaft and bearings - too tight increases oil pressure, too loose decreases it; 5. Clogged oil filter or oil pickup screen reducing oil pressure; 6. Faulty or malfunctioning relief valve; 7. Incorrect oil selection; 8. Oil leaks or blockages in the oil passages.
