Can an Automatic Transmission Vehicle Be Started in Neutral?

An automatic transmission vehicle cannot be started in neutral. While coasting in neutral is possible when the engine is running, it serves no practical purpose—neither saving fuel nor reducing operational effort—and is generally not recommended. Below are some key points regarding neutral gear: 1. Automatic transmission vehicles are typically programmed by the computer to set gears or automatically control fuel supply. Coasting in neutral does not achieve fuel savings. Additionally, the design of automatic transmissions differs from manual transmissions, and prolonged coasting in neutral can damage the transmission. 2. When coasting in neutral (N gear), the difference between the vehicle's speed and the engine's RPM can lead to insufficient oil pressure in the automatic transmission's hydraulic lines. This not only increases friction and reduces lubrication effectiveness but also damages the internal friction plates of the transmission.

Do You Need to Pay Purchase Tax When Buying a Used Car?

If the original owner has paid the purchase tax, the used car you buy does not need to pay it again. If the purchase tax was not paid when the car was new, then after the used car transaction, the new owner needs to pay the remaining purchase tax. Here are the details for selecting a used car: 1. First, check whether the car has oil leaks by lifting the vehicle and inspecting the chassis and engine. 2. Check the color of the engine oil. Start the car for three to five minutes, then insert the dipstick, pull it out, and wipe it dry with a tissue. If the oil is black, it is not recommended for consumers to purchase. 3. Make a preliminary judgment on the sound of the engine. If the engine makes loud noises during operation, it is not advisable to buy such a used car. 4. Inspect the car's craftsmanship by checking the interior for any unusual odors, whether the seats show signs of aging, and if the wiring ports are loose. 5. Examine the car's exterior to see if the paint is smooth and determine whether the glass is original.

What is the function of hydraulic transmission oil?

Hydraulic transmission oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays roles in energy transmission, wear resistance, system lubrication, corrosion prevention, rust prevention, and cooling within the hydraulic system. Hydraulic transmission oil is a high-quality hydraulic oil. The oil used as a transmission medium in hydraulic systems is called hydraulic oil, also referred to as hydraulic transmission oil or hydraulic fluid. Hydraulic transmission oil is an indispensable transmission medium in hydraulic systems. To meet transmission requirements, it must first have good viscosity-temperature characteristics. Within the operating temperature range, the oil's viscosity should change minimally with temperature, meaning it should have a high viscosity index. Additionally, it should possess excellent lubricating properties. Hydraulic oil not only serves as an energy transmission medium but also as a lubricant for mechanical movement. Good lubricity ensures the normal operation of machinery. A high-quality hydraulic transmission oil should also be pure, free from mechanical impurities, and non-corrosive. Moreover, it should resist oxidation, minimizing or avoiding the formation of oxides when temperatures rise, which can accelerate oil degradation and clog oil passages.

Where is the cigarette lighter in the Regal?

Regal's cigarette lighter is located inside the round cover at the bottom of the center console in front of the gear shift lever. It has two main functions: 1. Providing a cigarette ignition source for passengers. 2. Can be equipped with a car inverter to convert the vehicle's 12V, 24V or 48V DC power into 220V/50Hz AC power for ordinary electrical appliances. Additional information: 1. The car cigarette lighter power supply is generally 12V DC, with the central elastic head as the positive pole and the side clips as the negative pole. 2. It is directly connected to the car battery, with the same current and power specifications as the battery.

What are the disadvantages of long-term idling for a car?

The disadvantages of long-term idling for a car are as follows: 1. Wastes fuel, which is the most direct impact. When idling, the vehicle consumes approximately 2 liters of fuel per hour, meaning 16 liters would be consumed over 8 hours of idling. 2. Can lead to carbon deposits. Due to the low engine speed and poor air intake efficiency during idling, combustion is not very complete, making it easier for carbon deposits to form. 3. When the engine is idling, the temperature and pressure inside the cylinders are relatively low, prolonging the preparation time for fuel ignition. Additionally, the sealing of the cylinders decreases, making it easier for knocking sounds to occur, which can shorten the engine's lifespan. 4. The engine's air-fuel mixture becomes too rich, resulting in low oxygen content in the exhaust. The unburned mixture can ignite at the location of the three-way catalytic converter, potentially damaging it.
