Transmission working principle involves two turbine blades assembled in a space filled with hydraulic oil, connected to the power input and output ends respectively. The impeller at the power input end generates a powerful vortex to drive the impeller at the output end, thereby achieving power transmission. The functions of a transmission: Changing the transmission ratio to expand the range of torque and speed variations of the driving wheels; enabling the vehicle to reverse while maintaining the same engine rotation direction. Also known as a gearbox, the transmission is a mechanism used to alter the speed and torque from the engine, capable of fixing or changing the transmission ratio between the output and input shafts in steps. Classification of transmissions: Stepped transmissions use gear drives with several fixed transmission ratios; continuously variable transmissions (CVT) can obtain any transmission ratio within the variable speed range; integrated transmissions refer to hydromechanical transmissions composed of a torque converter and a stepped gear transmission.

How to Power Off a Car with One-Key Start?

Without pressing the brake, pressing the one-key start once will power off the car. When the car is stationary with the brake pressed and shifted into P gear, pressing the one-key start function will turn off the engine. Most cars nowadays are equipped with the one-key start function. Here are some related introductions: 1. Automatic Power-Off Function of One-Key Start: In fact, the original smart start system installed in the car has a protection system. If the engine is turned off for 10 minutes, the vehicle will automatically power off. This is mainly to prevent battery discharge, which could make it difficult to start the engine. 2. Other Functions of One-Key Start: Pressing the one-key start button without stepping on the brake can turn on some of the car's power sources. Pressing it twice in a row can turn on all the power sources in the car, allowing the car to enter the self-check procedure, and even the window lift function can be used. Additionally, the one-key start function can also open the trunk without the need to get out of the car.

How Far Can a Car Go Without Refueling?

How far a car can go without refueling depends on the fuel tank capacity of the vehicle. The specific details are as follows: 1. A car with a larger fuel tank can travel farther, while one with a smaller tank will travel less. 2. The calculation formula is: Distance that can be traveled when the fuel gauge shows "0" = (Remaining fuel when the gauge shows "0" ÷ Fuel consumption per 100 kilometers) × 100 kilometers. To avoid running out of fuel, you can use the following fuel-saving tips: 1. Avoid pressing the accelerator pedal too hard when starting: Pressing the accelerator pedal too hard when starting the car will increase fuel consumption, so you should press it gently to allow the car to start slowly. 2. Maintain a safe speed: Driving at a constant speed will reduce fuel consumption, preferably between 60 and 90 kilometers per hour. 3. Turn off the engine during prolonged traffic jams: Excessive idling time will significantly increase fuel consumption. If the car is parked for more than 5 minutes, you can turn off the engine. 4. Avoid driving at low speeds for extended periods: Maintaining a speed of 40 km/h for a long time will also consume a lot of fuel.

Can I Get a Refund If I Haven't Taken the Subject 1 Test?

You can get a refund if you haven't taken the Subject 1 test. For students who have passed the physical examination but have not taken the Subject 1 test, they can directly go to the driving school's registration office to complete the withdrawal procedures. The remaining balance will be refunded after deducting the fees for the training hours already completed. Notes for the Subject 1 Test: Candidates must enter the examination room with their ID card and admission ticket to take the test. Before the test, the system administrators have already entered the candidates' information into the corresponding computers. After entering the examination room, candidates only need to sit at the designated workstation assigned by the invigilator. There is no need to input personal information again. After verifying and confirming, candidates can press the 'Start Test' button to begin. During the test, press the keys with moderate force and click gently. Pressing too hard or holding the key down for too long may result in multiple answers. If this happens, press the 'Previous Question' button to return to the original question and answer again. If you encounter any computer system issues during the test, raise your hand to notify the invigilator for assistance. Do not press the 'Submit' button during the test.

Is it necessary to press the foot brake when starting in Subject 3?

When starting in Subject 3, the foot brake is not required (except for starting on a slope). When waiting at traffic lights on flat roads, only the clutch is needed for starting. Gradually release the clutch to the semi-engagement point, wait for the car to move forward, and then slowly release the clutch completely. This can reduce the likelihood of stalling. Below is relevant information about Subject 3: 1. Introduction: Subject 3, also known as the road test, is part of the motor vehicle driver's license assessment. It is the abbreviation for the road driving skills and safe civilized driving knowledge test in the motor vehicle driver's examination. 2. Test Content: The road driving skills test varies for different types of vehicles eligible for driving. It generally includes: preparation before getting on the car, starting, driving in a straight line, shifting gears, changing lanes, pulling over, driving straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crossings, passing school zones, passing bus stops, meeting oncoming vehicles, overtaking, making U-turns, and driving at night.

Where to Add Radiator Coolant?

Radiator coolant is added to the car's expansion tank. Open the engine hood and locate the expansion tank, which is usually spherical in shape. Remove the tank cap and add the appropriate amount of radiator coolant. The optimal filling level is between the MAX and MIN marks. Here are some related details: 1. Replacement Cycle of Radiator Coolant: Radiator coolant is generally replaced every two years. 2. Radiator Coolant Should Not Be Mixed with Water: Adding water can affect the performance of the radiator coolant, lowering its boiling point and reducing its cooling effectiveness. It also raises the freezing point, making it prone to freezing in cold climates. Ordinary tap water contains various impurities and ions, which can form scale over time and cause blockages. In emergency situations, adding water may be unavoidable, but it is recommended to use purified water, preferably distilled water, and not to add too much. 3. Shelf Life of Radiator Coolant: When adding radiator coolant, always check the shelf life. Typically, radiator coolant has a shelf life of about two years. Expired products should not be used. Choose high-quality coolant that matches the original color of your car or a universal type. Different brands and colors of radiator coolant have varying formulations, and mixing them can cause reactions that reduce their effectiveness.

What is the fuel tank capacity of the Yidong Plus?

Yidong Plus has a fuel tank capacity of 53 liters, which is the officially announced data. Owners who have purchased the Yidong Plus can also check this information on the vehicle's configuration sheet. The Yidong Plus requires 92-octane gasoline, with a fuel consumption of 5.6-5.8L per 100 kilometers. A full tank can provide a driving range of approximately 914 to 946 kilometers. During daily driving, it is important to always monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when there are about 2 segments remaining to avoid running out of fuel midway. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity marked by the manufacturer is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This space is designed to allow for fuel expansion when temperatures rise, preventing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
