What are the hazards of running the air conditioning while idling without turning off the engine?

Running the air conditioning while idling without turning off the engine can lead to carbon buildup in the car's engine and may even pose life-threatening risks. Here are the specific details: Causes engine carbon buildup: When the engine is idling, the throttle is in a critically closed state, resulting in minimal air intake. At this time, the engine operates in a rich fuel injection mode, and due to the overly rich air-fuel mixture, carbon deposits tend to accumulate more. If the air conditioning is also running, the engine needs to output additional power to avoid stalling, which typically raises the engine speed by about 50 RPM. This low-speed, load-bearing operation can lead to even more carbon buildup. May pose life-threatening risks: Prolonged idling with the air conditioning on can result in excessive carbon monoxide production due to the overly rich air-fuel mixture and incomplete combustion. Carbon monoxide is slightly lighter than air and can accumulate around the vehicle in windless conditions. This gas may then be drawn back into the air conditioning system, potentially causing oxygen deprivation and suffocation for passengers inside the car, leading to dangerous situations.

How Many Years Can Unused Tires Be Stored?

Unused tires can be stored for 4 to 5 years, with a maximum of no more than 5 years. The functions of tires are: 1. To support the entire weight of the vehicle and bear the load of the car; 2. To transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface, thereby improving the car's power performance, braking performance, and off-road capability; 3. To prevent severe vibrations and early damage to automotive components. The steps for replacing tires are: 1. After parking and turning off the engine, use the handbrake to secure the vehicle; 2. Place heavy objects in front of and behind the wheels to prevent sliding, and set up a triangular warning sign behind the car; 3. Use a wrench to loosen the screws of the tire to be replaced in a diagonal pattern; 4. Place the jack on the side where the tire needs to be replaced and lift the vehicle to a certain height; 5. Remove the screws and take off the tire; 6. Install the spare tire or new tire and tighten the screws in a diagonal pattern; 7. Lower the vehicle by releasing the jack and ensure that the screws and nuts are properly tightened.

Which is faster, rear axle ratio 4.11 or 4.33?

Rear axle ratio 4.11 is faster. Here's an introduction to rear axle ratios: 1. Ratio: The ratio refers to dividing the engine speed or motor rotation speed by the output rotation speed of the reducer, where 4.11 represents this output speed. 2. Rear axle ratio: The rear axle ratio is the gear transmission ratio of the main reducer in the vehicle's drive axle. It equals the ratio of the rotation angular velocity of the drive shaft to that of the axle half-shaft, and also equals their speed ratio. The rear axle ratio is an important parameter of the engine, commonly known as the rear axle ratio, and academically referred to as the main reduction ratio.

Are there more automatic transmission cars or manual transmission cars now?

Nowadays, cars are basically automatic transmission or semi-automatic. In terms of proportion, automatic transmission cars are more common. Here is the relevant introduction: 1. Automatic transmission cars: Automatic transmission cars usually use hydraulic transmission devices to replace the mechanical clutch of manual transmission cars, so there is no clutch pedal. When the engine speed is low, the torque transmitted by the liquid is limited and insufficient to push the car forward. When the gear lever is placed in the forward gear and the brake pedal is released, as the throttle is increased and the engine speed rises, the transmitted torque increases, pushing the car forward. 2. Advantages: Its advantage over manual transmission is that it is easier to drive.

What does CS new energy vehicle mean?

CS new energy vehicles refer to the Changan New Energy CS series of vehicles. The following is an introduction to new energy vehicles: 1. Introduction: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new types of on-board power devices), integrating advanced technologies in vehicle power control and driving, resulting in vehicles with advanced technical principles, new technologies, and new structures. 2. Types: New energy vehicles include four major types: hybrid electric vehicles (HEV), battery electric vehicles (BEV, including solar-powered vehicles), fuel cell electric vehicles (FCEV), and other new energy vehicles (such as those using supercapacitors, flywheels, and other high-efficiency energy storage devices). 3. Development: Throughout human history, there have been two major transformations in transportation energy power systems. Each transformation has brought significant changes to human production and life, while also contributing to the economic take-off of leading countries or regions.
