When the car's air conditioning is turned on, the power drops significantly because the car's air conditioning is powered by the engine. The compressor's power comes from the car's engine, so running the air conditioning consumes some of the engine's power. Here is an introduction to the related content: 1. Power: The power of a typical car's compressor is around 2-5 kW, and the engine's maximum power is achieved when the engine reaches 5000 RPM. 2. Implication: This means that when the engine is running at low speeds, its power output is only around 20-30 kW, so the air conditioning can consume up to about 20% of the engine's power at this time.

What Are the 8 Combustion States of Spark Plugs?

Spark plugs' 8 combustion states are closely related to various aspects of automobiles. Here is an introduction to spark plugs: 1. Introduction: The spark plug is a crucial component in a gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap to generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. 2. Requirements: (1) Gap requirement: The gap between the spark plug electrodes significantly impacts its performance. (2) Temperature requirement: The insulator skirt of the spark plug should maintain a temperature of 500-600°C. (3) Performance requirements: Key requirements for spark plugs include thermal characteristics, tensile strength, heat resistance, electrical conductivity, insulation strength, sealing performance, and corrosion resistance.

What does 'several oil' mean in cars?

In cars, 'several oil' refers to the amount of oil consumed per kilometer. Here is an introduction about fuel consumption: 1. Introduction: Constant-speed fuel consumption is the vehicle's fuel consumption per 100 kilometers obtained in the constant-speed driving fuel consumption test specified by national standards for certain types of vehicles. 2. Testing: The test can be conducted on the road or on a chassis dynamometer. The fuel consumption per 100 kilometers is then determined through the 'flow meter method' or 'carbon balance method'. During road tests, it is necessary to follow the standards specified in the national standards for test conditions, test methods, test road selection, etc. For chassis dynamometer tests, there are also regulations regarding dynamometer characteristics, laboratory conditions, vehicle preparation, test procedures, etc.
