What is the idle speed of a car engine?

Car engine idle speed is between 700 to 800 revolutions per minute. The effects of engine idling include: 1. Increased engine carbon deposits; 2. Shortened engine lifespan; 3. Overly rich air-fuel mixture in the engine, which can easily damage the catalytic converter; 4. Loosening of the vehicle's braking system, increasing the risk of accidents; 5. Increased exhaust emissions from the vehicle's cylinders. Car idling refers to the engine running without any load, only overcoming internal mechanical friction, without delivering any power output, maintaining the minimum stable operating speed of the engine. The idle speed can be adjusted by modifying the throttle opening and the idle fuel supply.

How to Determine the Quality of Gasoline?

Methods to determine the quality of gasoline are: 1. Smell it: The heavier the gasoline odor, the poorer the quality; 2. Observe it: Qualified gasoline is clear with no floating substances on the surface. Conversely, if the gasoline appears cloudy, stratified, or has suspended particles, it indicates potential quality issues; 3. Touch it: Dip your finger in the gasoline and rub it a few times. If the oiliness feels stronger, the gasoline quality is poor. If the gasoline evaporates quickly, it indicates good quality. Gasoline is a volatile, flammable liquid hydrocarbon mixture obtained from petroleum through distillation, cracking, or pyrolysis, and can be used as fuel. Sulfur compounds in gasoline can cause corrosion to objects, and it has the ability to resist detonation combustion under various usage conditions.
