How to Distinguish Good and Bad Gasoline?

There are several methods to distinguish good and bad gasoline: 1. Smell with your nose: The heavier the gasoline smell, or even irritating, the worse the quality. Poor-quality gasoline has a pungent, eye-stinging, or foul odor, indicating excessive sulfur content. The octane number is an agreed value for evaluating gasoline quality, so generally, gasoline with high sulfur content is not good. When smelling, do not directly sniff the gasoline; instead, gently wave your hand over the container opening to catch the scent. 2. Observe with your eyes: The color of gasoline can indicate its quality. Generally, 93# gasoline appears transparent yellow, and 97# gasoline appears emerald green. Qualified gasoline is usually very clear, with no floating objects on the surface, no suspended particles in the middle, no sediment at the bottom, and no stratification or turbidity. Conversely, if the gasoline appears turbid, stratified, with suspended particles or sediment, it indicates potential quality issues. 3. Touch with your hand: Dip your finger in the gasoline and rub it a few times. If your finger feels very oily, like engine oil, the gasoline quality is poor. Alternatively, pour a little gasoline on your hand; if it evaporates quickly, the gasoline quality is good.

Do New Cars Need an Oil Change in Winter?

New cars do not require a special oil change for winter. There is no need to specifically switch to winter-grade oil for new cars, as manufacturers have already pre-filled the engine with oil suitable for the sales region during production, ensuring it can handle local conditions. Engine Oil: Also known as motor lubricant. With a density of approximately 0.91×10 (kg/m³), it serves multiple functions for the engine: lubrication and friction reduction, auxiliary cooling, sealing against leaks, rust and corrosion prevention, and shock absorption. Often referred to as the "blood" of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent, determining the fundamental properties of the lubricant, while additives compensate for and enhance any shortcomings in the base oil's performance, providing additional capabilities. Additives are a crucial part of the lubricant. Effects of Low Temperatures on Engine Oil: In cold conditions, engine oil thickens and may not flow smoothly, sometimes even stopping completely. This delays its circulation to critical engine components, affecting lubrication and protection. Starting the vehicle and driving immediately can lead to dry friction, which over time may damage cylinder walls, cause abnormal engine noises, severe idle vibrations, and even oil burning issues.

Why is the Tower Crane Cab Not Located at the Bottom?

Tower crane cabs are not located at the bottom due to reasons such as visibility and sensors. The details are as follows: Visibility: Installing high-definition cameras in the cab allows for clear visibility of ground operations and surrounding conditions, enabling safer operation. Sensors: Data on azimuth, tilt angle, wind speed, and other factors can be obtained through various sensors. Tower Crane: A tower crane, also known as a 'tower hoist,' is the most commonly used lifting equipment on construction sites. It is assembled section by section (referred to as 'standard sections') and is used to lift construction materials such as steel bars, wooden formwork, concrete, and steel pipes. Tower cranes are indispensable equipment on construction sites. Certifications Required to Operate a Tower Crane: Operating a tower crane requires a special operation qualification certificate for tower cranes. Tower crane operators are classified into three levels: Junior (National Vocational Qualification Level 5), Intermediate (National Vocational Qualification Level 4), and Senior (National Vocational Qualification Level 3).
