What is the difference between iridium and platinum spark plugs?

The differences between iridium and platinum spark plugs are reflected in the following aspects: 1. In terms of performance: Iridium spark plugs perform better than platinum ones. Since iridium has a higher melting point than platinum, it can be made finer, providing stronger ignition with lower required voltage, reducing misfire rates, and offering excellent chemical corrosion resistance. 2. In terms of stability: Iridium spark plugs are more pressure-resistant and stable than platinum ones. Typically, standard resistor spark plugs last 20,000 kilometers, platinum spark plugs last 40,000 kilometers, while iridium spark plugs can last between 60,000 to 80,000 kilometers.

Is It Necessary to Apply an Invisible Car Wrap?

It is necessary. Here is the relevant introduction: 1. Definition of Invisible Car Wrap: An invisible car wrap is essentially a high-performance, new type of environmentally friendly film widely used in the automotive film beauty and maintenance industry. It is a transparent protective film with super toughness. After application, it isolates the car's paint surface from the air, protecting against acid rain, oxidation, and scratches. It is applied to various parts of the car to provide long-lasting protection for the paint. 2. Types of Invisible Car Wraps: Invisible car wraps on the market are generally divided into two materials: PVC and TPU. PVC material is relatively hard, not easy to wrap around edges, and has weaker scratch resistance, but it provides excellent protection for the paint surface. It is relatively cheaper and typically lasts 2-5 years. TPU material is softer and more flexible, but as the saying goes, you get what you pay for—it is more expensive and generally lasts 5-10 years. Both materials offer some level of UV protection, and besides preventing scratches and acid rain, they also help prevent the car paint from yellowing and fading.

Where is the cabin air filter located in a Chevrolet Epica?

Chevrolet Epica's cabin air filter is located behind the glove compartment in front of the front passenger seat. Below are the functions of the cabin air filter: 1. Provides fresh air: Prevents windshield fogging to maintain driver visibility; Supplies fresh air to the cabin, protecting occupants from harmful gases and ensuring driving safety; Effectively sterilizes and deodorizes. 2. Ensures hygiene and safety: Maintains clean cabin air to prevent bacterial growth and creates a healthy environment; Effectively separates solid impurities from air such as dust, powder particles, and grinding residues; Effectively blocks pollen to prevent allergic reactions that may affect driving safety. 3. Adsorbs harmful substances: Adsorbs moisture, soot, ozone, odors, carbon oxides, SO2, CO2, etc. from the air; Provides strong and durable moisture adsorption. 4. Filters solid impurities: The automotive cabin air filter fits tightly against the housing to ensure unfiltered air doesn't enter the cabin. Separates solid impurities like dust, pollen, and grinding particles from the air.

What is the Difference Between 92 Octane Gasoline and Ethanol Gasoline?

The difference between 92 octane ethanol gasoline and 92 octane gasoline is that ethanol is added to 92 octane ethanol gasoline. Below are the relevant details about 92 octane gasoline and ethanol gasoline: 1. Different characteristics: Ethanol gasoline uses fuel ethanol as a gasoline additive, making it environmentally friendly, clean, and renewable. In contrast, regular automotive gasoline uses chemical additives such as MTBE, which causes significant environmental pollution. Many countries have already banned the use of MTBE and similar additives. 2. Different evaporation potential: Ethanol has a higher evaporation potential, approximately twice that of gasoline. This characteristic can improve engine thermal efficiency and serve as a beneficial factor for cooling the engine. 3. Different advantages: Ethanol gasoline has a lower heat value—only 61% compared to regular gasoline. This means more fuel is required to travel the same distance. Despite its significantly lower heat value than gasoline, theoretically, the heat value of the air-fuel mixture is very close to that of gasoline, making ethanol suitable for use as a fuel in gasoline engines.

How to Lower the Vehicle Height?

To lower the vehicle height, you can install shorter springs, replace them with coilover suspensions, or modify the air suspension. Effects of lowering the vehicle height: 1. It can improve the car's appearance and enhance visual appeal; 2. It can increase stability during high-speed driving. However, whether it improves handling cannot be guaranteed, as many cases show that improper modifications often result in worse handling than before. Related information: While modifying coilover suspensions can lower the chassis, it may affect ride comfort. Air suspension allows height adjustment when needed without compromising comfort. About air suspension modification: Air suspension is common in many high-end models, adjusting height via inflation and deflation. Installing air suspension requires an air tank and pump, typically placed in the trunk. Of course, a lower chassis isn't always better—moderate adjustments are advisable, as excessively low clearance can reduce road passability.

How to Defog a Car?

If the fog is not heavy, you can open a small gap in the side windows. As the temperature inside the car gradually approaches the outside temperature, the fog will dissipate. The most common method is to use the air conditioning's cold or warm air in combination with the defog button. Press the defog button and lower the temperature to achieve the defogging effect. This is the most primitive and rudimentary method—use a dry cloth to wipe the glass, taking advantage of traffic jams or red lights to quickly clean it.
