Rolls-Royce Cullinan uses ZF's 8AT transmission. The functions of the transmission are: 1. Change the transmission ratio; 2. Expand the torque and speed of the driving wheels; 3. Enable the car to reverse; 4. Facilitate gear shifting or power output. The Rolls-Royce Cullinan is an SUV under Rolls-Royce, with a length, width, and height of 5341mm, 2164mm, and 1836mm respectively, and a wheelbase of 3295mm. In terms of power, the Cullinan is equipped with a 6.7-liter twin-turbocharged V12 engine, with a maximum power of 420 kilowatts, a maximum torque of 850 Newton-meters, a maximum power speed of 5000 revolutions per minute, and a maximum torque speed of 1600 revolutions per minute.

What is the difference between coasting in neutral and coasting in gear?

The specific differences between coasting in neutral and coasting in gear are as follows: 1. Operational difference: Coasting in neutral means shifting into neutral and relying on the car's inertia to move forward. Coasting in gear means remaining in gear without pressing the clutch or accelerator. 2. Fuel efficiency: When coasting in neutral, the engine may cause increased transmission wear due to poor lubrication. However, when coasting in gear, the vehicle's fuel injection decreases and gradually drops to zero. The vehicle remains in the "ignition" state, and the farther it coasts, the more fuel is saved. 3. Safety: If the car stalls suddenly while coasting in neutral, the engine, vacuum-assisted braking system, and hydraulic power steering system will stop working. This may lead to loss of control and potential accidents. In contrast, coasting in gear is safer because the car remains in the ignition state, allowing other systems to remain operational in case of emergencies, ensuring timely response and safety.

What to Do If a Car Uses Deteriorated Gasoline?

It is necessary to completely remove the remaining gasoline in the fuel tank and refill with higher-quality gasoline. Additionally, the fuel injectors and combustion chamber need to be cleaned, and the fuel filter and fuel pump should be replaced to prevent clogging by impurities. Below are the reasons for gasoline deterioration: 1. Exceeding the shelf life: Most gasoline has a shelf life of 3 months, which can be extended to 6 months in a sealed environment. The composition of gasoline includes volatile substances such as octane, which gradually evaporate due to storage conditions and prolonged placement, leading to gasoline deterioration. 2. Water contamination: If water droplets or vapor mix into the gasoline, it can cause solidification. Water molecules mixed into the gasoline can produce bacteria in the engine, causing damage. 3. Oxidation: Among the components of gasoline, hydrocarbons are most prone to react with oxygen. After oxidation, gasoline produces an acidic odor.

Why is there no sound when playing music via Bluetooth in a Volkswagen Polo?

This is because the car audio volume is not turned on, and the user needs to enable it. Some phones (such as iPhones) have music playback programming that is incompatible with certain car models' pairing codes, so they can only answer calls but not play music, requiring a change in the Bluetooth playback frequency band. If the car's Bluetooth multimedia music is not enabled, it needs to be set to on. If the media audio on the phone is not turned off, it may cause signal interference with the Bluetooth function. Some users may experience no sound after connecting their phone's Bluetooth to the car's Bluetooth. In this case, the user should enter the phone's Bluetooth settings interface, where there are two options: phone audio and media audio. After connecting to the car's Bluetooth, both options are enabled by default. The media audio should be turned off while keeping the phone audio on. This ensures that the three functions—Bluetooth calls, car music playback (or radio), and phone navigation announcements—do not interfere with each other.

What are the reasons for no low pressure in car air conditioning?

There may be several reasons for no low pressure in car air conditioning: 1. Reversed live and neutral wires of the air conditioning power supply: Main manifestations: This usually only occurs during the installation of car air conditioning. Solution: Reconnect the live and neutral wires. 2. Damaged fan or capacitor in the indoor or outdoor unit: Main manifestations: If the outdoor unit fan is damaged, the main symptoms are excessive exhaust temperature or high pressure; if the indoor unit fan is damaged, it manifests as frost formation on the indoor unit. Solution: Replace the damaged fan or capacitor in the indoor (outdoor) unit. 3. Refrigerant leakage or substandard refrigerant quality: Main manifestations: Both the indoor and outdoor units of the car are working, and the compressor is also operating, but the car air conditioning has no cooling effect. Solution: Check whether it is caused by refrigerant leakage or quality issues in the car air conditioning, and promptly add or replace the refrigerant.
