Automatic transmission and manual transmission differ in the following aspects: 1. Operation: Automatic transmission does not require clutch operation, having only brake and accelerator pedals; manual transmission requires clutch operation for manual gear shifting and reversing. 2. Working principle: Automatic transmission uses planetary gear mechanisms for gear changes, automatically adjusting based on accelerator pedal position and vehicle speed; manual transmission changes gear positions and transmission ratios by moving the gear lever to alter gear engagement within the transmission. 3. Gear indicators: Automatic transmission gear indicators are marked as P, R, N, D; manual transmission gear indicators are marked as 1, 2, 3, 4, 5, 6, R, etc.

Automatic and manual transmissions feel quite different to drive. I usually drive a manual, and in traffic jams, constantly pressing the clutch with my left foot can be a bit tiring, but the sense of control during gear shifts is fantastic—accelerating and decelerating entirely by manually operating the clutch and gear lever makes it feel like the car is completely under my command. Automatic transmissions are different; just shift into D, and the system handles gear changes automatically. In traffic, you only need to control the throttle and brake with your right foot, making it much easier. While automatics are convenient, throttle control isn't as precise, especially when overtaking uphill—it often feels a bit sluggish. Manuals allow techniques like downshifting and rev-matching, which can save some fuel costs, whereas automatics are simpler but usually consume a bit more fuel.

Where is the thermostat located in the Wuling Hongguang 1.2 engine?

The thermostat in the Wuling Hongguang 1.2 is installed in the engine outlet pipe joint. You can find it by following the radiator pipe towards the position near the engine block. The function of the thermostat is to automatically adjust the amount of water entering the radiator based on the temperature of the coolant, changing the circulation range of the water to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. The relevant introduction to the thermostat is as follows: 1. The thermostat automatically adjusts the amount of water entering the radiator based on the coolant temperature, changing the water circulation range to regulate the cooling system's heat dissipation capacity, ensuring the engine operates within the appropriate temperature range. 2. If the main valve of the thermostat opens too late, it will cause the engine to overheat; if the main valve opens too early, it will prolong the engine warm-up time, causing the engine temperature to be too low.

Is It Necessary to Apply the Brakes in School Zones?

Approximately 30 meters before entering a school zone, lightly apply the brakes to reduce speed below 30 km/h, observe the surroundings to ensure safety, and then proceed slowly. Key considerations when driving through school zones: Always slow down promptly, pay attention to the conditions on both sides of the road or the surroundings, and yield to students crossing the street. Especially during school hours or after dismissal, be prepared to stop for students and children crossing the road. When students are crossing, come to a complete stop and let them pass; avoid honking or driving alongside them. Heed warning signs. Most school zones are marked with warning signs indicating the presence of a school ahead. Upon seeing these signs, drivers must reduce speed and increase vigilance. In emergencies, avoid making left or right turns. If an emergency arises while driving, remember that the first response should be to brake, especially when approaching intersections—do not turn left or right. Check blind spots carefully. When driving near schools, be extra cautious when changing lanes or making turns. Students on bicycles may not ride slowly, and their small size makes them harder to spot. Therefore, when turning, not only should you check the mirrors and use turn signals, but also turn your head to check blind spots and ensure there are no obstacles before proceeding. Always be alert to the possibility of children darting out unexpectedly. Follow road deceleration instructions. When passing near schools or crosswalks, drivers must check for students waiting to cross the street and ensure it is safe before proceeding. Upon seeing speed bumps near school entrances, slow down to avoid driving too fast, which could lead to collisions with students playing nearby. Parking is prohibited at school entrances. Parking spaces near schools are often limited, and illegal parking for pickups and drop-offs is common, posing safety risks to children.
