You should not shift to Neutral (N) gear while driving an automatic car. The Neutral gear, also known as freewheeling, poses risks to the braking system, transmission system, and even life safety. Damage to the braking system from freewheeling: Prolonged freewheeling, such as when descending a hill, can cause the vehicle to accelerate due to gravity, requiring constant braking. However, continuous braking raises the temperature of the braking system, potentially vaporizing the brake fluid and leading to accidents. Damage to the transmission system from freewheeling: Freewheeling also negatively impacts the transmission system. Similar to "low-gear driving" when going downhill, the vehicle's drivetrain uses internal resistance (through the friction plates between the engine and transmission) to control speed, acting as an internal brake at high speeds. Shifting to Neutral removes this engine control. Life safety hazards of freewheeling: When freewheeling, the engine and transmission are disconnected, eliminating internal braking effects. If the vehicle ahead stops suddenly while the following vehicle is freewheeling, the latter must rely solely on wheel braking, increasing the risk of rear-end collisions and endangering the lives of the driver and passengers.

What is the function of an automotive oil filter?

The function of an automotive oil filter is to remove impurities, gum, and moisture from the engine oil, delivering clean oil to various lubrication points. The method for replacing an automotive oil filter is as follows: 1. Warm up the engine; 2. Use a machine to extract the old oil; 3. Remove the old oil filter and replace it with a new one; 4. Add new oil. The working principle of an oil filter: As impurities accumulate on the filter paper, the permeability of the filter paper continuously decreases, and the flow resistance increases, causing the oil pressure on the outer side of the filter paper to rise. When the oil pressure is sufficient to open the bypass valve, the oil no longer passes through the filter paper but directly enters the central tube through the bypass valve, then flows out from the oil outlet in the middle of the oil filter base plate and into the engine lubrication system to participate in lubrication.

What does it mean when the thermometer light on the car comes on?

The thermometer light on the car coming on indicates that the engine coolant temperature is too high. The reasons for this are: 1. Insufficient or leaking coolant causing the temperature to rise; 2. A malfunctioning radiator fan resulting in the vehicle running at high speeds and generating heat that cannot be dissipated in time; 3. A problem with the circulation water pump, preventing the normal operation of the water circulation on the engine's heat conduction side, leading to a failure in the engine cooling system. Precautions when the thermometer light on the car comes on: 1. It is not advisable to continue driving when the temperature light on the dashboard flashes; wait for the temperature to drop before inspecting and repairing; 2. Do not immediately turn off the engine; 3. Do not splash cold water on the engine to cool it down, as this can cause the engine block to cool suddenly and crack.
