Automotive transmission serves the purpose of changing speed and torque, as well as enabling the vehicle to reverse and idle in a stationary position. The transmission is a crucial component in a vehicle, equally important as the engine, and it includes both manual and automatic transmissions. An automatic transmission consists of two main parts: the transmission mechanism and the control mechanism. The primary function of the transmission mechanism is to alter the magnitude and direction of torque and rotational speed, while the control mechanism is responsible for managing the transmission mechanism to achieve changes in the transmission ratio, i.e., gear shifting, thereby adjusting speed and torque. Automatic transmissions encompass various types such as AT (automatic transmission), DCT (dual-clutch transmission), CVT (continuously variable transmission), and AMT (automated manual transmission).

Simply put, a car transmission is the component that manages the vehicle's power. I can feel the engine's strength while driving, all thanks to its adjustments. When starting or climbing hills, lower gears make the engine push harder, while shifting to higher gears on highways saves fuel and ensures smoothness, preventing the car from struggling. Manual transmissions offer more flexibility—I often enjoy shifting gears for fun, whereas automatics let me relax. Regularly changing transmission oil prevents wear, and checking fluid levels avoids leaks. This component requires careful use to extend its lifespan and save on repair costs—it's quite important. In short, it acts like the car's power conductor, ensuring the right amount of force is delivered.

The invoice code and invoice number are printed in black.

Is It Safe to Place Solid Air Fresheners in the Car?

Placing solid air fresheners in the car can be hazardous, so it is best to avoid doing so. The ingredients of popular air fresheners on the market mostly consist of ether, aromatic fragrances, and other components. When these ingredients are released into the air, they decompose and deteriorate, becoming pollutants themselves. Composition of Solid Air Fresheners: Solid air fresheners are composed of ethanol, fragrances, deionized water, and other ingredients. They mask unpleasant odors by emitting fragrances, thereby reducing discomfort caused by bad smells. Shape of Solid Air Fresheners: Solid air fresheners are water-based gel substances with no fixed shape, requiring container packaging. The direction of fragrance emission is limited, and the scent is often too faint. Additionally, this gel does not fully evaporate, leaving residues behind, and the packaging becomes waste that pollutes the environment.

Is There a Penalty for Exceeding the Time Limit in Subject 2?

Exceeding the time limit in Subject 2 results in penalties. For example, the reverse parking maneuver must be completed within 210 seconds; otherwise, it will be deemed as a failure. Below are the penalty standards for Subject 2: 1. General Requirements: Not using the seatbelt as required results in a 100-point deduction; causing the engine to stall once due to improper operation results in a 10-point deduction. 2. Reverse Parking: Not following the prescribed route or sequence results in a 100-point deduction; the vehicle body crossing the line results in a 100-point deduction; failing to complete the parking maneuver results in a 100-point deduction; stopping midway results in a 5-point deduction each time. 3. Parallel Parking: After the vehicle is parked, if the vehicle body crosses the line, it results in a 100-point deduction; (when exiting the parallel parking) if the tires touch or run over the solid center line of the lane during movement, it results in a 10-point deduction.

What Type of Oil Should a Tractor Use?

Tractors should use CF-grade diesel engine oil. Classification of diesel engine oil grades: The letter 'C' represents diesel engine oil. From CA, CB, CC, CD, CE, CF, CF-4, CG-4, CH-4, CI-4, to CJ-4, the further the letter in the alphabet, the higher the quality grade of the oil. Generally, CD-grade oil is sufficient for diesel engines, while turbocharged diesel engines require higher-quality oil. Precautions for using tractor oil: Some agricultural machinery operators neglect the maintenance of their tractors, especially failing to add or change the oil in a timely manner. Unbeknownst to them, oil that has been used for a long time contains more impurities and can damage the engine. Some even go years without checking the oil dipstick or adding oil, continuing to operate the engine with insufficient oil, which further reduces the tractor's service life.

Can I Register a Vehicle Locally If I Purchase Compulsory Traffic Insurance in Another Region?

Purchasing compulsory traffic insurance in another region does not affect vehicle registration. As long as the vehicle has a formal invoice, certificate of conformity, purchase tax, and compulsory traffic insurance, you can complete the registration procedures in your place of residence. The risks of purchasing compulsory traffic insurance in another region are as follows: Claim Settlement Risks: Purchasing compulsory traffic insurance in another region requires handling procedures in that area. Although insurance companies now offer nationwide claim settlements, there is competition even within the same company. Many branches would rather increase investigation costs than collaborate with other branches of the same company, which raises the cost and difficulty of claim settlements for customers. Premium Risks: With the networking of the national auto insurance inquiry platform, it is believed that customers' claim records will be accessible across regions. As a result, the discounts for purchasing insurance in another region may no longer exist, and insurance premiums may not decrease—they might even increase.

Does Sleeping in a Car with the Air Conditioning On Affect the Vehicle?

Sleeping in a car with the air conditioning on during summer has little impact on the vehicle apart from increasing fuel consumption. However, it may pose certain risks to the occupants, as sleeping in a car with the engine running can lead to carbon monoxide poisoning. Here are the specific details about car air conditioning: 1. Introduction: The car air conditioning system, abbreviated as car AC, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to optimal conditions. It provides a comfortable environment for passengers, reducing travel fatigue, and creates favorable working conditions for the driver, playing a crucial role in ensuring safe driving. Generally, it includes cooling, heating, and ventilation systems. This integrated system makes efficient use of the limited space inside the vehicle, featuring a simple structure and ease of operation, making it a popular modern car air conditioning system internationally. 2. AC Layout: Different types of air conditioning systems have varying layout methods. Currently, most cars use a combined heating and cooling air conditioning system. The layout typically involves assembling the evaporator, heater core, centrifugal blower, and control mechanisms together, referred to as the air conditioning unit assembly.
