Does idling with the AC on damage the car and consume more fuel?

Idling with the AC on does damage the car and consumes more fuel. Here are the relevant explanations: 1. Increased air intake: The engine control unit raises the engine speed by about 100 RPM, thereby increasing the engine's air intake. This leads to more fuel injection and a richer air-fuel mixture. The engine computer uses this method to improve engine stability. However, a richer mixture can result in incomplete combustion of gasoline. Prolonged idling with the AC on can cause increased carbon deposits, making the engine less fuel-efficient. 2. Cooling fan: When the AC is on, the engine needs to reduce the heat from the AC condenser, so the cooling fan runs continuously. If there are issues with the cooling or heat dissipation systems, it can lead to high engine coolant temperature, which may adversely affect the engine.

Should You Repair or Replace a Car Tire with a Nail Puncture?

It depends on the location of the puncture and the extent of the damage. If the nail only punctures the tread, the tire can be repaired and continue to be used. However, if the nail punctures the sidewall, it is recommended to replace the tire directly. Note: If a tire is punctured, do not remove the nail immediately; instead, drive to a nearby repair shop for assistance. Additional information is as follows: 1. The role of car tires: Car tires are one of the essential components of a vehicle, directly contacting the road surface and working with the suspension system to absorb shocks during driving, ensuring a comfortable ride and smooth driving experience. They also provide good traction between the wheels and the road, improving the vehicle's traction, braking, and off-road capability. Additionally, tires bear the weight of the car, and their importance is increasingly recognized. 2. If the tire's tread is punctured by a nail: As long as the nail is not too thick, it can be repaired at a professional repair shop. For slightly larger holes, a mushroom plug can be used, though this method is more costly. If the sidewall is punctured, it is best to replace the tire. The sidewall is the weakest part of the tire and undergoes constant deformation and recovery during rotation. Forcing a repair may cause the patch to peel off or, in the case of a mushroom plug, damage the sidewall's cords, leading to bulging. After repair, most shops will perform wheel balancing, so the tire can be used safely. However, sidewall punctures are best addressed by replacement rather than repair. Repaired tires are not suitable for long-term use or high-speed driving. If highway travel is necessary, it is advisable to replace the tire to avoid potential safety hazards.

What is the function of OBC in new energy vehicles?

New energy vehicle OBC is a power electronic device for charging the on-board power battery, namely the on-board charger, which can safely and reliably complete the charging management of the power battery. Purpose of the on-board charger: The on-board charger is an accessory used to charge digital products anytime and anywhere. This is a type of on-board charger commonly used for vehicle battery power supply. It is widely used in the field of lithium battery charging for various portable and handheld devices. The first function of the on-board charger is the automatic protection chip of the computer, which allows it to be used with confidence anywhere, providing perfect protection for the device during charging. Protection of electrical appliances: The plug structure of the on-board charger has a built-in fuse. In case of overvoltage or excessive current, the fuse will automatically blow to protect the machine's safety. The on-board charger also has a USB interface, which supports various USB interface power outputs. It can charge mobile phones through the power output interface.

What is the fuel consumption of the Tiggo 7 Shenxing 2?

The fuel consumption of the Tiggo 7 Shenxing 2 is approximately 9L per 100 kilometers. The following factors affect fuel consumption: 1. Environment and road conditions: Low temperatures cause the vehicle to take longer to warm up the engine, leading to higher fuel consumption. Actual user vehicle conditions vary greatly, and factors such as road surface, slope, dryness or wetness, curves, and mountainous roads all impact actual fuel consumption. 2. Driving conditions: Driving conditions have the greatest impact on fuel consumption. Frequent city driving results in higher fuel consumption; normal highway driving leads to lower fuel consumption; frequent short trips mean the vehicle operates at ideal temperatures for less time, also increasing fuel consumption. 3. Number of passengers or cargo weight: Vehicle weight significantly affects fuel consumption. When there are more passengers or the trunk is fully loaded with cargo, fuel consumption is inevitably higher. Therefore, minimizing unnecessary items in the vehicle can help save fuel.

What Are the Reasons for a New Car Lacking Power?

Here are specific explanations regarding the reasons a new car may lack power: Driving Habits: Poor power in a new car can be related to driving habits. Keeping your foot on the clutch while pressing the accelerator will prevent the car from gaining speed. Avoid keeping your foot on the clutch constantly, as it can lead to accidents and causes the clutch to remain in a working state. This shortens the clutch's lifespan, leading to clutch slippage, poor clutch separation, and high repair costs. After shifting gears, remove your foot from the clutch pedal. Engine Break-in Issues: If the engine isn't properly broken in, its power won't be fully realized. Therefore, after a period of break-in, the new car should be driven at high speeds. The full power of a new car typically becomes evident about six months after the break-in period.
