What does the ACC position on a car's ignition switch mean?

ACC stands for Adaptive-Cruise-Control in English, which means adaptive cruise control power supply, providing power to some components such as the car audio system. A car's ignition switch generally has four positions: START, ON, ACC, and LOCK. Typically, when the car is parked and turned off, the key is in the LOCK position, where the vehicle's circuit is disconnected, and the entire car is powered off. Additionally, the steering wheel is locked. When the key is in the ACC position, some electrical devices in the vehicle are powered, such as the radio and audio system, but other components of the car remain unpowered. This is the main difference between ACC and ON. When the key is in the ON position, all components of the car are powered, including the engine system. The START position is for starting the engine; once the key is turned to START, the starter motor is powered and begins working. There are many buttons in a car, each with different functions, such as the window control button, window lock button, mirror adjustment button, and lumbar support adjustment button. The window control button allows the window to be fully lowered or raised with just one press, freeing the driver's left hand and enhancing driving safety and convenience. Higher-end models may offer one-touch control for all four windows, along with anti-pinch protection, where the window automatically lowers if it encounters an obstacle to prevent injury. The window lock button, when pressed, locks all windows except the driver's side window to prevent accidental operation by children. Some vehicles only lock the rear windows, depending on the model. The mirror adjustment button typically has this layout: to adjust the left mirror, move the toggle switch to the left and adjust accordingly, and vice versa for the right mirror. Many people don't know what the four-way button in a car is for—it's actually for adjusting lumbar support, usually found only in high-end models. The horizontal button adjusts the intensity of the lumbar support, while the vertical button adjusts the position of the support to suit different drivers or passengers.

How Many Kilometers Should You Change Your Engine Oil?

For the timing of engine oil changes, it is generally recommended to follow the vehicle's user manual, which suggests changing the oil every 5,000 kilometers or every 6 months, whichever comes first. Types of Engine Oil: Engine oil can be divided into three types: full synthetic oil, semi-synthetic oil, and mineral oil. Engine Oil Specifications: The packaging of engine oil often displays specifications such as 5w30, 0w20, or 5w40, which indicate the oil's type. The 'w' stands for 'winter,' meaning that if the oil has the letter 'w,' it can be used during winter. Precautions for Oil Change: When the viscosity of the engine oil changes significantly under high temperatures, it is generally considered necessary to replace the oil if the kinematic viscosity at 100 degrees Celsius deviates by more than 20%. Additionally, if the oil's detergency and dispersancy performance decline, it may no longer effectively dissolve and disperse the carbon deposits produced during engine operation.

What are the brands of motorcycle piston rings?

Motorcycle piston ring brands include: MAHLE, Yijian, Leopard Truck Parts, Times Auto, Foton Auto Parts, JETechDesign, etc. Definition of Piston Ring: A piston ring (Piston-Ring) is a metal ring used to fit into the piston groove. Piston rings are divided into two types: compression rings and oil rings. The compression ring is used to seal the combustible gas mixture in the combustion chamber; the oil ring is used to scrape off excess oil from the cylinder. Functions of Piston Rings The roles of piston rings include sealing, oil control (oil regulation), heat conduction (heat transfer), and guidance (support). Sealing: Refers to sealing the combustion gas, preventing the gas in the combustion chamber from leaking into the crankcase, minimizing gas leakage to improve thermal efficiency. Gas leakage not only reduces engine power but also deteriorates the oil, which is the primary task of the compression ring; Oil control (oil regulation): Scraping off excess lubricating oil from the cylinder wall while ensuring a thin oil film remains for normal lubrication of the cylinder, piston, and rings, which is the main task of the oil ring.

What lights should be turned on when driving straight at night?

When driving straight at night, low beam headlights should be used. If the road ahead is completely dark with no road lighting facilities, high beam headlights should be turned on. If you encounter an oncoming vehicle, switch to low beam headlights in advance, and after passing the vehicle, decide whether to turn on the high beam headlights again based on the situation. When driving straight through an intersection at night, low beam headlights should be used. There is also a suggestion to alternately use high and low beam headlights as a signal. When passing through an uncontrolled intersection without traffic signals, you should slow down and alternately use high and low beam headlights as a signal. When overtaking at night, turn on the turn signal in advance and observe the vehicles behind. If the following vehicle is too close, it is not recommended to use the turn signal for overtaking, as this may easily catch the following vehicle off guard. In case of rainy or foggy weather with low visibility, the correct approach is to turn on the width marker lights, front and rear fog lights, and hazard warning lights. Note that fog lights are very bright and have a strong warning effect, so they should not be turned on during clear nights.
