What is the difference between 0w20 and 5w40?

0w20 and 5w40 are introduced as follows: 1. Different viscosity: 0w20 engine oil has a thinner viscosity and saves fuel consumption; 5w40 engine oil has a higher viscosity and consumes more fuel. 2. Different fuel consumption: 0w20 can withstand a minimum of minus 35 degrees, while 5w40 can withstand a minimum of minus 30 degrees. Engine oil starting with 0 has better cold start performance in winter than 5; 0w20 engine oil saves fuel consumption and has better cold start performance in winter compared to 5w40. 3. Different applicable car series: 0W20 is purely winter engine oil, while 5W40 is suitable for most northern regions. Moreover, most car series using 0W20 are Japanese and Korean cars, and the factory standard engine oil is 0W20. On the other hand, 5W40 engine oil is more widely available in the market and is very common and suitable for most Volkswagen models.

How Many Driving Modes Does a Train Have?

There are four main driving modes for trains, as detailed below: 1. Automatic Train Operation (ATO) Mode: The system handles all driving, detection, monitoring, and control tasks, while the driver only needs to supervise the normal operation of the equipment. 2. Protected Manual (PM) Mode under ATP Supervision: The train's monitoring, operation, braking, and door opening/closing (including platform screen doors at underground stations or safety barriers at elevated stations) are manually operated by the driver under the supervision of onboard ATP equipment. The ATP subsystem ensures operational safety, with the driver manually controlling the train based on auxiliary driving information displayed on the DMI and DTI. ATP provides complete automatic protection for train operation, and all necessary driving information is displayed on the onboard signal monitor. 3. Restricted Manual (RM) Mode: The train operates at a speed not exceeding 25 km/h. The driver manually controls monitoring, operation, braking, and door operations, while onboard equipment provides overspeed protection at 25 km/h and supervises train integrity, door status, and rollback. 4. Non-Restricted Manual (NRM) Mode: The driver uses the ATC cut-off selector switch to deactivate ATC. This bypass switch blocks ATC emergency brake output and other signals that prevent train movement. The train is entirely manually driven without onboard equipment control. The driver operates the train according to dispatch orders and ground signal indications, with safety ensured by interlocking devices, dispatchers, and the driver collectively.

What methods can be used to remove engine oil?

Engine oil can be treated using four methods: alcohol, olefin materials and turpentine, using oil to remove oil, and essential balm. The details are as follows: 1. Alcohol: Engine oil is a mixture of several alkanes and is an organic substance. According to the principle of "like dissolves like," organic substances can be used to dissolve engine oil, but it is best to choose an organic substance that is also soluble in water to avoid secondary pollution. The most convenient option is alcohol, which can dissolve in both organic solvents and water. The higher the alcohol concentration, the better, with anhydrous alcohol being the best. 2. Olefin materials and turpentine: For engine oil stains on clothes, you can first use gasoline to wipe them. If the stains are too heavy, olefin materials and turpentine can be used. After the stains dissolve, wash them with regular detergent. For stains on the collar, use a piece of absorbent cotton no smaller than a cigarette box soaked in gasoline and gently pat from the center of the collar outward. Do not use too little gasoline, as it may not remove the dirt and could leave gasoline stains. 3. Using oil to remove oil: If the stain is oily and does not absorb water, use "oil to remove oil"—wipe with a soft cloth or cotton dipped in gasoline to dissolve the oily color substance into the gasoline, then transfer it to the cloth. If gasoline cannot dissolve the stain, use chemicals with stronger oil-dissolving capabilities, such as benzene, chloroform, or carbon tetrachloride. For oil stains, sprinkle some raw flour on the stained area and brush with a palm fiber brush until the stain is removed. Then, use a rattan stick to beat the area and remove excess flour, making the fabric fluffy and clean. For oil stains on ski jackets, mix a small amount of flour with cold water to form a paste, apply it to the stain, and after a few hours, brush off the powder with water to remove the stain. 4. Essential balm: For small amounts of oil, using essential balm makes cleaning easy. Even stubborn oil stains can be removed.

Can a New Car Be Washed?

A new car can be washed, but the frequency of washing should not be too high. Reasons why frequent car washing is not recommended: Frequent washing can damage the car's paint, accelerating its oxidation. The car wash solution used must be a specialized neutral one; acidic or alkaline solutions should be avoided as they can harm the paint surface. After applying the car wash solution, it is essential to rinse thoroughly with a high-pressure water gun. Incomplete rinsing can lead to corrosion of the paint by residual wash solution. Methods for washing a car: If conditions permit, opt for a manual dust-free car wash facility. Use a neutral and mild detergent during the wash, and ensure separate towels are used for washing and drying. Finally, apply appropriate protective agents to areas like the tires, bumpers, and wheel arches to prevent aging.
