What kind of oil should be used for Volkswagen Tharu?

Volkswagen Tharu uses 5w-40 or 0w40 fully synthetic original engine oil. For later maintenance and oil changes, you can choose from brands such as Mobil, Shell, and Castrol. Any 40-viscosity oil that meets Volkswagen's 502 certification can be used. For Volkswagen Tharu 1.4T and 2.0T models, 5w-40 fully synthetic oil is recommended. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity—5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the oil's kinematic viscosity at 100°C. A higher number means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the oil in a Tharu is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain out; Use a specialized wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add new oil through the engine valve cover filler port, typically filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick to check that the oil level is within the standard range.

How to Signal When Overtaking the Vehicle Ahead?

Overtaking the vehicle ahead involves the following signaling methods: 1. Turn on the left turn signal, observe the rear-view mirror to check for vehicles behind, and pay attention to changes in traffic conditions ahead; 2. Honk the horn or alternately switch between high and low beams to alert the vehicle ahead. Overtaking should be done from the left side for the following reasons: different driving styles, obstructed visibility when overtaking from the right, which compromises safety, while the left side provides better visibility, requiring only a slight deviation to the left to observe the road ahead. Precautions for overtaking include: 1. Choose the right moment to overtake, when there are fewer vehicles ahead or behind or the road is relatively flat; 2. Activate the left turn signal in advance to alert vehicles behind, and return to the normal lane promptly after overtaking; 3. Use the horn appropriately to alert the vehicle ahead of your intention to overtake and to yield; 4. Use high beams and hazard lights in combination to alert oncoming vehicles for safety; 5. Avoid forcing an overtake.

What are the types of oil pumps?

Oil pumps are a type of hydraulic pump. In fact, there are many hydraulic pumps in automobiles, such as the power pump for hydraulic power steering and the oil pump for automatic transmissions. In hydraulic transmission control devices used in construction machinery, hydraulic pumps that generate power sources are essential. Generally, there are two types of oil pumps: one is the gear oil pump, and the other is the rotor oil pump. Gear oil pumps are divided into internal gear oil pumps and external gear oil pumps. The gear oil pump consists of a drive shaft, drive gear, driven shaft, driven gear, housing, etc. Two gears with the same number of teeth mesh with each other and are installed inside the housing. The radial and end clearances between the gears and the housing are very small. The drive shaft is key-connected to the drive gear, and the driven gear is mounted on the driven shaft. During operation, the drive gear drives the driven gear to rotate in the opposite direction. As the two gears rotate, the oil filled between the gear teeth is carried from the inlet chamber to the outlet chamber along the housing wall. On the side of the inlet chamber, a vacuum is created due to the disengagement of the gears and the continuous removal of oil, causing the oil in the oil pan to enter the inlet chamber through the filter under atmospheric pressure. On the other side of the outlet chamber, the oil is pumped out under a certain pressure through the meshing of the gears and the continuous squeezing of the oil. The rotor oil pump is a type of cycloidal gear pump that uses inner and outer rotors to pump lubricating oil. The rotor oil pump mainly consists of inner and outer rotors, such as the oil pump body and oil pump cover. The driving inner rotor and the driven outer rotor are installed inside the oil pump housing. The inner rotor has four convex teeth, and the outer rotor has five concave teeth. The inner rotor is fixed to the drive shaft, while the outer rotor can rotate freely within the oil pump housing, with a certain eccentricity between them. During operation, the inner rotor drives the outer rotor to rotate in the same direction. Due to the eccentricity and tooth profile of the two rotors, the tooth surfaces of the inner and outer rotors maintain line contact at any angle, forming four working chambers between the teeth of the inner and outer rotors. Since the inner rotor rotates faster than the outer rotor (with a transmission ratio of 5:4), when a working chamber rotates from the inlet, the rotors disengage, the volume gradually increases, creating a vacuum. Lubricating oil is sucked in from the inlet. As the rotors continue to rotate, the lubricating oil is carried to the other side of the outlet. At this point, the rotors engage, the volume of the oil chamber gradually decreases, the oil pressure increases, and the oil is squeezed out between the teeth and sent out through the outlet.

How to Solve Electric Vehicle Charging Issues?

Do not accelerate abruptly. When going uphill or against the wind, it's best to assist with pedaling, which benefits both your battery and motor. Wait until the red light turns on before floating charging for an additional 1-2 hours. Avoid overloading or excessive weight during operation. When the instrument shows insufficient battery, switch to manual pedaling. Frequent sudden braking consumes battery capacity; higher designed speeds lead to greater battery wear. Prevent overcharging. Since prolonged exposure to sunlight affects battery lifespan, avoid leaving the battery under direct sunlight.
