What is Automotive Glass Grease Film?

Automotive glass grease film refers to a layer of oily impurities adhering to the glass, primarily originating from sources such as vehicle exhaust, cooking fumes, insect remains, bird droppings, tree resin, fruit jam, and other external contaminants. During the use of automotive glass, small pores gradually develop over time. These pores absorb external impurities and pollutants, thereby forming a grease film. Moreover, automotive grease film is difficult to remove. Using wipers with windshield washer fluid only makes the glass increasingly blurry and can refract light, impairing visibility. This is because the grease film contains impurities like dust, tree sap, or car wax, and ordinary windshield washer fluid has limited cleaning effectiveness. Toothpaste can be used to remove the grease film, as it contains abrasive particles that provide a polishing effect. When using toothpaste to clean the grease film, it's important to apply the right amount of pressure and wipe evenly to better clean the glass surface pores and eliminate the grease film. Using an eraser, detailing clay, or newspaper can also be effective. Newspaper has some oil-absorbing properties, and dipping it in water to wipe repeatedly several times can clean the surface. Detailing clay works similarly—it's economical and effective but more time-consuming and labor-intensive. A more professional approach to removing grease film from glass is to use a dedicated grease film cleaner. Spray the cleaner evenly on the glass, then wipe it with a car wash towel or sponge for excellent cleaning results.

What speed is 30 mph?

30 mph is approximately 48.25 kilometers per hour. Miles per hour (mph, short for miles-per-hour) is commonly referred to as "mph" in Chinese, where 1 mph = 1.609344 kilometers per hour. Introduction: The distance a vehicle travels in a unit of time is referred to as vehicle speed. Common units are kilometers per hour or meters per second. Vehicle speed is one of the three parameters used to describe traffic flow and holds significant importance in traffic flow theory research. Classification: Vehicle speed can also generally refer to motor vehicle speed. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed.

What are the test rules for the hill start in Subject 2?

The rules for the hill start in Subject 2 are as follows: After the vehicle starts, if it rolls back between 30 cm and 50 cm, 20 points will be deducted; if it rolls back more than 50 cm, the test will be failed; if the vehicle does not start within 30 seconds, the test will be failed. When preparing to start on the slope, remember to first turn on the turn signal, then release the clutch. When the vehicle body begins to shake, slowly release the brake. However, after slowly releasing the clutch, if the vehicle shows obvious shaking, you can slowly release the brake to test whether the vehicle can move forward. If you notice the vehicle rolling back or lacking power, immediately press the brake and restart. If the vehicle starts to roll back, you must brake to prevent it from rolling further. Note that you must turn on the turn signal when starting; otherwise, 10 points will be deducted. If the vehicle runs over the solid edge line of the road during the test, 100 points will be deducted. During the hill start, the coordination between the clutch, accelerator pedal, and parking brake lever is crucial. The timing of releasing the parking brake lever is key: releasing it too late will prevent the car from starting and may cause it to stall; releasing it too early will cause the car to roll back. The right timing is when the clutch pedal is lifted to the semi-engaged position, which requires mastering the following techniques: first, listen to the engine sound; second, feel the shaking of the vehicle body; third, observe the tachometer.

What brand is PHC clutch?

PHC clutch is a brand of Valeo. The Korean PHC clutch is a clutch brand produced by a joint venture factory established in 1988 by the Korean Pyeonghwa Clutch Company and the French automotive parts manufacturer Valeo. The PHC clutch three-piece set includes the clutch pressure plate, clutch driven plate, and clutch release bearing. Introduction to PHC clutch: Clutch pressure plate: The clutch pressure plate is the most important component in the clutch assembly, directly determining whether the clutch installation will shake and how long it will last. The PHC clutch pressure plate uses advanced diaphragm spring manufacturing technology, ensuring the best balance between the clamping force and pedal force, greatly reducing installation rework rates and improving driving comfort. Clutch driven plate: The quality of the clutch driven plate determines the overall service life of the clutch and its vibration damping and noise reduction effects. The PHC clutch uses fifth-generation friction linings that are asbestos-free, lead-free, and free of volatile solvents, meeting the Euro V environmental standards. The optimal hardness ensures high wear resistance and the best comfort. Release bearing: The clutch release bearing is a critical part of the clutch release system, and its quality determines the separation efficiency of the clutch system and the wear rate on the pressure plate fingers. The PHC clutch release bearing is made of engineering plastic, significantly reducing its weight and wear on the release fingers.

What is the structure of a gasoline engine?

Gasoline engines vary greatly depending on their application, manufacturer, and production era. However, they all consist of the engine block group, crankshaft and connecting rod mechanism, valve train, intake and exhaust systems, fuel system, cooling system, lubrication system, starting system, and harmful emission control devices. Introduction: A gasoline engine is an internal combustion engine that converts internal energy into kinetic energy using gasoline as fuel. Due to gasoline's low viscosity and rapid evaporation, a fuel injection system can spray gasoline into the cylinders. After compression reaches a certain temperature and pressure, a spark plug ignites the mixture, causing the gas to expand and perform work. Characteristics: Gasoline engines are characterized by high rotational speed, simple structure, light weight, low cost, smooth operation, and ease of maintenance and repair. They are widely used in automobiles, especially in small cars.
