How Many Hours of Theoretical Class for Subject 4?

What brand is the Corolla CVT?

The CVT in the Corolla is produced by Aisin (a subsidiary of Toyota) in Japan. Composition of the CVT transmission: The main components of the CVT system include the driving pulley set, driven pulley set, metal belt, and hydraulic pump. This type of transmission uses a belt and variable-diameter pulleys to transmit power, allowing the drivetrain to achieve optimal matching with the engine's operating conditions. Advantages of the CVT transmission: Unlike conventional automatic transmissions, the CVT does not have gear sets, which eliminates the associated shift shock. As a result, the power output of the CVT is linear, providing a very smooth driving experience. Theoretically, the CVT transmission system can have an infinite number of gear ratios, allowing for more flexible gear settings. It also makes it easier to achieve a balance between gear ratios, speed ratios, performance, fuel consumption, and emissions in traditional drivetrain systems. The mechanical efficiency and fuel economy of CVT transmissions are significantly better than those of conventional automatic transmissions, second only to manual transmissions, offering much better fuel efficiency.

What are the methods for engine maintenance?

Engine maintenance methods include: 1. Regularly change engine oil and oil filter; 2. Maintain good crankcase ventilation; 3. Periodically clean the fuel system; 4. Regularly clean the radiator; 5. Periodically clean the crankcase. An engine is a machine that can convert other forms of energy into mechanical energy, suitable for power generation devices. Engines are classified by structural function into: 1. External combustion engine: Fuel burns outside the engine; 2. Internal combustion engine: Fuel burns inside the engine; 3. Gas turbine: Combustion produces high-pressure gas, which is used to rotate the turbine blades and output power.

How to Deal with ESP Malfunction Display in a Car?

Car displaying ESP malfunction can be handled by: reducing driving speed and avoiding excessive steering and turning. The function of ESP is to monitor the driving state of the car, helping the vehicle avoid deviating from its trajectory during emergency obstacle avoidance, understeer, or oversteer in turns. The types of sensors in the ESP system and their functions are divided into: 1. Steering sensor: monitors the steering wheel rotation angle; 2. Wheel speed sensor: monitors the speed of each wheel; 3. Yaw rate sensor: records the movement of the car around the vertical axis; 4. Lateral acceleration sensor: detects the centrifugal force generated when the car turns.

Is there a warning if the hood is not closed properly?

If the front hood is not closed properly, the central control panel will not display a warning, but there will be a prompt on the dashboard. The dashboard will show that the engine hood is not closed. If this warning appears, you should not continue driving. Instead, press the hood firmly to close it properly before driving. Below is some additional information about the hood: 1. Classification: Front hood, mid-engine hood, rear hood. 2. Functions: (1) Airflow guidance: The shape of the hood can effectively adjust the direction of airflow relative to the car's movement and the resistance it generates, reducing the impact of airflow on the car. Through guidance, air resistance can be decomposed into beneficial forces, increasing the force of the front tires on the ground, which helps improve the car's driving stability. (2) Protection of the engine and surrounding pipeline components: By improving the strength and construction of the hood, it can fully prevent adverse effects such as impact, corrosion, rainwater, and electrical interference, ensuring the normal operation of the vehicle. (3) Aesthetics: The exterior design of a vehicle is a visual representation of its value. As an important part of the overall appearance, the hood plays a crucial role in enhancing the visual appeal and embodying the concept of the entire car.

How to Reset Tire Pressure on the New Mazda 3?

The method to reset the tire pressure on the new Mazda 3 is to turn on the ignition, press and hold the tire pressure monitoring reset button until you hear a "ding" sound, then release it. The tire pressure monitoring system will store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, completing the tire pressure reset. Hazards of Low Tire Pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Causes the steering wheel to feel heavy and may lead to veering, which are factors detrimental to driving safety; Increases the movement of various parts of the tire, causing abnormal heating due to excessive rolling; Reduces the functionality of the cords and rubber, leading to delamination or cord breakage, and excessive friction with the rim, causing damage to the bead area and abnormal wear; Multiplies the friction between the tire and the ground, causing a sharp rise in tire temperature, softening the tire, and drastically reducing its strength. High-speed driving may lead to tire blowouts; Increases tire deformation, making the sidewalls prone to cracking, and generates flexing movements, leading to excessive heat, promoting rubber aging, fatigue of the cord layers, cord breakage, and also increases the tire's contact area with the ground, accelerating shoulder wear.

What are the hassles of registering a vehicle in a different location?

If you plan to transfer the vehicle to your local area in the future, it might not be possible due to factors like emission standards or vehicle age. Additionally, when purchasing a car from another location, most 4S dealerships do not offer free first maintenance. Registering the vehicle in a different location can also cause issues with annual inspections, as you would need to return to the place of registration for the inspection. Some local free benefits may also be unavailable. Below are specific inconveniences of having an out-of-town license plate: 1. Lost license plate: If your vehicle license or plate is lost, you can only apply for a replacement at the vehicle's registered location. Driving without a license plate is prohibited, and doing so could result in penalties like a 12-point deduction, so you must promptly go to the registered location for a replacement. 2. Annual inspection: Although policies support cross-region annual inspections, the procedures, required documents, and rules vary by location. 3. Traffic restrictions: Large cities with high populations often impose travel restrictions on vehicles with out-of-town plates. For example, in Beijing, vehicles with non-local plates cannot enter within the 5th Ring Road during rush hours, and in Tianjin, non-local vehicles are barred from entering the inner ring road.
