Why Does a Lower Gear Provide More Power?

Torque is essentially a moment of force, where the magnitude of the moment is directly proportional to the length of the lever arm and the size of the applied force. In cars, the larger gear in a lower gear position is equivalent to a longer lever arm. The force applied is determined by the throttle input—the higher the engine speed, the greater the force output. Therefore, at the same engine speed, a longer lever arm results in a larger moment of force, which translates to greater torque in the car. Lower gears inherently provide a longer lever arm, thus delivering higher torque. 1. How a Car Transmission Works: Each gear has a different gear ratio, akin to the meshing of a small gear with a large gear to produce varying speeds. At low speeds, a lower gear ratio (3rd gear and below) is used, where the output shaft speed is lower than the engine speed. According to the formula P=FV, this allows for greater driving force. At high speeds, a higher gear ratio (4th gear and above) is employed, with the output shaft speed exceeding the engine speed, reducing traction to achieve higher speeds. Shifting gears essentially involves selecting different-sized gears to mesh with the output shaft gear. 2. Using Lower Gears for Uphill and Downhill Driving: (1) Uphill Driving with Lower Gears: Based on the transmission principles mentioned above, it's clear that a car engine delivers constant power. Lower gears provide greater traction at low speeds. When starting, the maximum friction from the ground must be overcome to move the car, making it essential to use 1st or 2nd gear for starting. (2) Downhill Driving with Lower Gears: Unlike uphill driving, relying solely on brakes to control speed during a long descent can cause the brake discs to overheat, leading to thermal fade. The most severe consequence is a drastic reduction in braking performance, resulting in brake failure. Therefore, using a lower gear to engage engine braking is necessary to assist in slowing the vehicle.

Where is the Auto Start-Stop Button on the Volkswagen Tiguan?

The auto start-stop button is located on the right side of the gear lever, marked with an 'A'. By default, it is in the 'on' state. To turn it off, simply press the button once. Below is a detailed introduction to the Volkswagen Tiguan: Configuration Parameters: The Shanghai Volkswagen Tiguan offers a total of 7 models across 4 versions: Urban Edition, Trendline, Comfortline, and Flagship. These models are equipped with Volkswagen's flagship 1.8TSI and 2.0TSI engines, delivering outstanding performance in both power and fuel efficiency. Paired with a 6-speed manual transmission or an Aisin 6-speed automatic transmission, the power is better utilized, providing robust performance while also being more environmentally friendly in terms of emissions. Compared to its prototype, the Volkswagen Tiguan, the Tiguan's body length has been increased by 68mm, and the wheelbase reaches 2684mm, placing it in the upper-middle level among its peers, aiming to meet the usage demands of Chinese consumers. The Tiguan's trunk capacity can be freely adjusted between 400L and 1530L, greatly enhancing its practicality, which is a key point of focus for an SUV model. Versions: Mainly divided into BlueMotion and Enjoyment versions.

How many points are deducted for crossing the yellow line in Subject 2?

Crossing the yellow line in the Subject 2 driving test results in an immediate failure, deducting 100 points. The evaluation criteria for each item in the Subject 2 test are as follows: 1. Reverse parking is judged according to the following rules: failure to follow the prescribed route or sequence results in failure; the vehicle body crossing the line results in failure; incomplete parking in the reverse position results in failure; stopping midway results in failure. 2. Hill start and stop are judged according to the following rules: if the front bumper of the car or the front axle of the motorcycle does not stop on the designated line and exceeds 1250px, it results in failure; exceeding the specified time for starting results in failure; if the front bumper of the car or the front axle of the motorcycle does not stop on the designated line but does not exceed 1250px, 10 points are deducted; if the vehicle body is more than 750px away from the edge line after stopping, 10 points are deducted.

Is it allowed to make a U-turn at an intersection without a U-turn sign?

It is allowed to make a U-turn at an intersection without a U-turn sign. Vehicles can make a U-turn at intersections where left turns are permitted and there are no signs or markings prohibiting U-turns. It is important to note that vehicles must proceed according to the left-turn signal without affecting the normal movement of other vehicles. If making a U-turn at an intersection with a left-turn waiting area, vehicles can first enter the left-turn waiting area when the straight-ahead signal is green and wait until the left-turn signal turns green to complete the U-turn. Scenarios where U-turns are prohibited include: U-turns are prohibited where there are signs prohibiting U-turns or left turns: If there is a sign prohibiting U-turns, then U-turns are not allowed at that intersection. Since a U-turn is an extension of a left turn, intersections with signs prohibiting left turns also prohibit U-turns. U-turns are prohibited at crosswalks: U-turns are not allowed at crosswalks. If making a U-turn at an intersection where it is permitted, the vehicle must cross the crosswalk before turning around and cannot make the U-turn on the crosswalk. U-turns are prohibited when there is no left-turn lane: Even in the leftmost lane, if there is no sign permitting left turns, U-turns are not allowed. U-turns are prohibited from the second left-turn lane: When a vehicle is in the second left-turn lane, it cannot make a U-turn. In the absence of any directional signs, U-turns are only permitted from the innermost left-turn lane.

Is an Appointment Required for Maintenance?

Maintenance requires an appointment. Below is relevant information about automotive maintenance: Automotive maintenance refers to the preventive work of regularly inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of a vehicle, also known as vehicle upkeep. Modern automotive maintenance primarily includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and more. The purpose of automotive maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. Generally, the maintenance cycle for a car is the first maintenance at 5,000 kilometers; then at 10,000 kilometers, 15,000 kilometers, 20,000 kilometers, up to 60,000 kilometers, with maintenance every 5,000 kilometers in between. It is usually divided into minor maintenance and major maintenance. Major maintenance is typically performed every 10,000 kilometers, while minor maintenance is done every 5,000 kilometers. The oil and oil filter are replaced approximately every 5,000 kilometers. The air filter is replaced at 10,000 kilometers. The fuel filter and cabin air filter are replaced at 30,000 kilometers. The transmission lubricant is replaced between 30,000 and 40,000 kilometers. Spark plugs and injector cleaning are maintained or replaced every 30,000 kilometers. Throttle valve carbon cleaning is performed every 10,000 kilometers. Brake pads do not have a fixed replacement time; they are replaced when inspection indicates it is necessary. Engine cleaning is performed every 30,000 kilometers.
