Should an automatic transmission car be put in P or N gear at traffic lights?

An automatic transmission car should be put in N gear at traffic lights. It is not recommended to put it in P gear when waiting at a red light, because when the vehicle is parked in P gear waiting for the red light, the transmission will lock the gears. If the car is rear-ended at this time, the transmission will be directly cracked, causing the transmission to be completely scrapped. The following is relevant information about traffic lights: 1. When waiting for a short time at a red light, you can stay in D gear and press the brake or pull the handbrake; when waiting for a long time at a red light, it is recommended to shift to N gear and then pull the handbrake to relieve driving fatigue. 2. The P gear in an automatic transmission is designed to assist parking, where the gears are locked by the engagement of the ratchet and pawl inside the transmission. This is basically the same as parking a manual transmission car, except that special gears are used. The ratchet and pawl are not 100% fitted, leaving a certain gap. This design is to avoid damaging the transmission due to a collision after engaging the P gear.

What is the difference between a 6-cylinder engine and a 4-cylinder engine?

The difference between a 6-cylinder engine and a 4-cylinder engine lies in the number of cylinders. Here are the specific differences between a 6-cylinder and a 4-cylinder engine: 1. A 6-cylinder engine has 6 cylinders; a 4-cylinder engine has 4 cylinders. 2. A 6-cylinder engine has two more sets of pistons than a 4-cylinder engine, with four additional compression rings and two additional oil rings, increasing the contact and friction area by approximately 30%. 3. An L4 engine is more compact, lighter, and has a lower failure rate compared to a V6 engine. Here is some relevant information about 4-cylinder engines: 1. A 4-cylinder engine, also known as a 4-cylinder power unit, is a machine that converts one form of energy into another more useful form of energy. 2. The engine body consists of the cylinder block, crankcase, cylinder head, and cylinder gasket components. 3. The engine is the device that provides power to the car, determining its power, fuel efficiency, stability, and environmental friendliness. 4. The engine is the device that provides power to the car, converting the thermal energy of gasoline and diesel into mechanical energy by burning and expanding gases in a sealed cylinder to push the pistons and perform work.

Should I turn on the left turn signal when overtaking?

When overtaking, you should turn on the left turn signal. Overtaking should be done from the left side of the vehicle in front. After overtaking and maintaining a necessary safe distance from the overtaken vehicle, turn on the right turn signal and return to the original lane. According to Article 47 of the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China, when overtaking, motor vehicles should turn on the left turn signal in advance, switch between high and low beams, or sound the horn. Here are the relevant details about overtaking: 1. On roads without a center line or with only one motor vehicle lane in the same direction, when the vehicle in front receives an overtaking signal from the vehicle behind, it should reduce speed and give way to the right if conditions permit. 2. The vehicle behind should overtake from the left side of the vehicle in front after confirming there is sufficient safe distance. After maintaining a necessary safe distance from the overtaken vehicle, turn on the right turn signal and return to the original lane.

Why is the fan still running after the car is turned off?

It is normal for the fan to continue running after the car is turned off. When the engine coolant temperature is higher than the acceptable soak temperature for the engine at the moment of parking, the vehicle's computer will automatically calculate the fan's operating speed and duration, thereby controlling the fan's operation. Below is an introduction to why the fan may still be running after the car is turned off: 1. The higher the engine temperature, the longer the fan will run after parking. When the engine coolant temperature drops below the soak temperature, the fan will turn off, protecting the engine and extending its service life. 2. The car radiator consists of three parts: the inlet chamber, the outlet chamber, and the radiator core. The coolant flows inside the radiator core, while air passes outside the radiator. The hot coolant cools down as it dissipates heat to the air, and the cold air warms up by absorbing the heat from the coolant.

What to Do If You Buy a Stock Car?

If you purchase a stock car, you can request the 4S store to replace the car, refund the payment, and compensate for any losses. If you choose not to replace the car, you can ask for a partial refund and negotiate for discounts on future maintenance and repairs. These maintenance and repair discounts should be included in the purchase contract to prevent any future disagreements. Tips to maximize benefits when buying a stock car: 1. Price: A stock car cannot be compared to a new car, and the price should be discounted accordingly, typically around 30% lower than a new car. 2. Maintenance: Since a stock car has been stored for some time, you can request the 4S store to inspect components such as the engine oil, battery, rubber seals, and tires. If any wear or aging is found, demand replacements.
