The following are the benefits of 98 octane gasoline: 1. Performance and environmental aspects: Higher anti-knock performance and power, reduced harmful substances in gasoline and exhaust pollution. 2. Economic aspects: Enables pursuit of higher engine power with smaller displacement, improving both power and fuel economy. The following is related information about 98 octane gasoline: 1. Introduction: 98 octane gasoline is gasoline whose octane rating is equivalent to a mixture of 98% isooctane and 2% n-heptane. Engines with high compression ratios should use high-octane gasoline. If a high-compression engine uses low-octane gasoline, it can cause abnormal combustion, leading to knocking, increased fuel consumption, and reduced driving power. Compared to other grades of gasoline, 98 octane gasoline has strong anti-knock properties and high combustion value, providing more powerful performance. However, due to its high grade and price, it is mostly used by luxury cars and is often referred to as 'premium gasoline.' 2. Standards: The country has strict standards for automotive gasoline. It not only requires gasoline to have a certain octane rating (commonly known as the gasoline grade) but also imposes strict regulations on the content of various chemical components in gasoline. If the olefin content is too high, the gasoline cannot burn completely, producing a gummy substance that accumulates in the intake manifold and valve guide areas. When the engine is at normal operating temperature, there are no abnormal phenomena; however, when the engine is shut off and cooled for a period, these deposits can stick the valve in the valve guide. Starting the engine at this time can cause valve sticking.

Is the Clutch on the Left or Right?

The clutch is on the left, the accelerator pedal is on the right, and the brake pedal is located between the clutch pedal and the accelerator pedal. The clutch pedal is the control device for the clutch assembly in a manual transmission car, serving as the 'human-machine' interaction part between the car and the driver. It is one of the five major control components in car driving, whether during learning or normal driving. The car clutch is located inside the flywheel housing between the engine and the transmission. While driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and transmission, thereby cutting off or transmitting the power input from the engine to the transmission.

How to Turn on the Heating Air Conditioning in Volkswagen Tiguan?

Method to turn on the heating air conditioning in Volkswagen Tiguan: 1. Start the car and wait for about 5 minutes until the water temperature rises to the normal level, then you can turn on the heating. 2. Adjust the air conditioning circulation mode to the internal circulation setting, and then use the temperature adjustment switch to set the temperature to the red heating position. Note that you do not need to turn on the AC in winter when using the heating, because the car's heating is not provided by the compressor but by the coolant passing through the heating radiator. The Volkswagen Tiguan is a car produced by Shanghai Volkswagen, offering a total of 4 versions and 7 models, including Urban, Trendline, Elite, and Flagship editions.

What type of gasoline should motorcycles use?

Motorcycles can use either 90 or 93 octane gasoline. Extended relevant information is as follows: 1. Compression ratio: Refueling should follow the principle of suitability. It can be determined based on the engine's compression ratio. For compression ratios below 9, 90 octane is sufficient; for those below 9.5, 93 octane is appropriate. If the compression ratio is high and the gasoline octane is low, it can easily cause knocking, damaging the engine. 2. Gasoline octane: Since engines with different compression ratios operate at varying temperatures, their requirements for anti-knocking also differ. For the same octane gasoline, the higher the engine's compression ratio, the more likely it is to produce greater knocking. Therefore, engine manufacturers generally specify the suitable gasoline octane for vehicles when they leave the factory.

What does the yellow engine light on the dashboard mean?

The yellow engine light on the dashboard indicates an engine malfunction. There are two scenarios when this light illuminates: 1. When the vehicle's power is turned on, the system performs a self-check. During this process, not only the engine yellow light but also other warning lights will illuminate simultaneously and then turn off together, which is a normal phenomenon; 2. If the engine malfunction yellow light remains illuminated after the vehicle is started, it means the ECU is alerting the owner that there is an engine malfunction, which is an abnormal condition. When the engine warning light on the dashboard is on, it cannot be manually reset. Typically, the issue needs to be diagnosed and resolved at a 4S shop using specialized fault detection equipment before the light can be turned off.
