Is the Launch Gear in Toyota CVT Transmissions Actually Useful?

2 Answers

Toyota CVT transmissions do not utilize launch gears. Below is relevant information about CVT transmissions: 1. Introduction to CVT Transmissions: CVT transmissions are a common type of automatic transmission, widely used in most automatic household vehicles. The internal structure of a CVT transmission is extremely simple, consisting of only two cone pulleys and a steel belt. 2. Working Principle of CVT Transmissions: The operation of CVT transmissions is also straightforward. The steel belt can move along the cone pulleys, allowing the transmission to vary speed and torque. During gear shifts, CVT transmissions exhibit almost no noticeable jerking. 3. Advantages of CVT Transmissions: CVT transmissions offer benefits such as simple structure, compact size, fewer components, low manufacturing costs, lightweight design, and smooth shifting performance.

I think the launch gear in Toyota's CVT transmission is indeed useful, which is quite evident from my car repair experience. It's like a hidden helper that takes over when the car just starts, using gears to directly transmit power, avoiding CVT belt slippage at low speeds, making the start quicker and more powerful. Compared to traditional CVTs, it reduces the feeling of acceleration lag, making driving smoother, especially in urban traffic jams—no sluggishness when stopping and starting again. At the same time, it also improves fuel efficiency because gear transmission is more efficient with less energy loss. In the long run, this design reduces transmission wear and extends its lifespan. Toyota has implemented this innovation in models like the Corolla, and I've seen many owners report much better responsiveness. Overall, the launch gear isn't redundant—it compensates for the weaknesses of CVT, making the overall performance more reliable.

What to Use When Car Air Conditioning Breaks Down?

You can install a fan with ice, but it is best to have it repaired. Here is a detailed introduction about car air conditioning: 1. Introduction: The car air conditioning system, abbreviated as car AC, is used to adjust and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to the optimal state. It provides a comfortable riding environment for passengers, reducing travel fatigue, and creates good working conditions for the driver, playing an important role in ensuring safe driving. Generally, it includes a refrigeration unit, heating unit, and ventilation unit. This combined system makes full use of the limited space inside the car, with a simple structure and easy operation, making it a popular modern car air conditioning system internationally. 2. Layout: Different types of air conditioning systems have different layout methods. Currently, most cars widely use an integrated heating and cooling air conditioning system. Its layout involves assembling the evaporator, heater radiator, centrifugal blower, and control mechanism together, referred to as the air conditioning unit assembly.

What Causes the Clicking Sound When Shifting into Reverse Gear?

Transmission Structural Design: The reverse gears in automotive transmissions are generally straight-cut spur gears. This type of gear inherently produces a 'clicking' sound upon engagement due to direct collision during meshing. Although most gears in manual transmissions are helical gears, which require gradual engagement unlike spur gears that can mesh directly, all three reverse gears are designed as straight-cut spur gears. Improper Operation: Another common cause of the 'clicking' sound when shifting into reverse during daily driving is improper operation. Unlike forward gears, reverse gears in most vehicle transmissions lack synchronizers. This necessitates that the vehicle must be completely stationary, and the clutch must be fully depressed for a few seconds before engaging reverse gear. Failure to do so will result in pronounced gear grinding noises and accelerate transmission gear wear.

What are the conditions for vehicle purchase tax refund?

For vehicles that have already paid the vehicle purchase tax, taxpayers are allowed to apply for a tax refund if they meet one of the following conditions: 1. Vehicle return: The vehicle is returned to the manufacturer or dealer. Required materials: A return certificate and return invoice issued by the manufacturer or dealer. 2. Eligible for tax exemption: Non-transport vehicles with fixed equipment that meet the tax exemption conditions but have already been taxed. If vehicle registration has not been completed, provide the original tax payment voucher and the original and duplicate tax payment certificates. If vehicle registration has been completed, provide the original tax payment voucher and the original tax payment certificate. 3. Legal provisions: Other situations where a tax refund should be granted according to laws and regulations. If vehicle registration has not been completed, provide the original tax payment voucher and the original and duplicate tax payment certificates. If vehicle registration has been completed, provide the original tax payment voucher, the original tax payment certificate, a motor vehicle cancellation certificate issued by the vehicle management authority of the public security organ, or other materials required by the tax authority.

What does it mean when the yellow exclamation light in the car comes on for a while and then disappears?

The reason why the yellow exclamation light in the car comes on for a while and then disappears may be an intermittent fault, most likely related to the oxygen sensor. Introduction: Automotive sensors are input devices for the car's computer system. Function: They convert various operating condition information (such as vehicle speed, temperature of various media, engine operating conditions, etc.) into electrical signals and transmit them to the computer to ensure the engine operates in the optimal state. Definition: When troubleshooting faults related to automotive sensors, in addition to checking the sensor itself, it is also necessary to inspect the wiring harness, connectors, and relevant circuits between the sensor and the electronic control unit.

Is an automatic transmission fuel consumption of 8 liters per 100 km considered high?

An automatic transmission fuel consumption of 8 liters per 100 km is considered normal. Here are some relevant explanations: 1. Driving habits: Car fuel consumption varies slightly depending on each individual's driving habits and skills. Smooth driving habits result in lower fuel consumption, while aggressive driving behaviors such as frequent overtaking and high RPM operations will appropriately increase fuel consumption. 2. Summer air conditioning system check: Air conditioning malfunctions are a significant cause of high fuel consumption. Poor cooling performance will require higher fan speeds and lower temperature settings to achieve a cooling effect. 3. Frequent hard braking: Frequent hard braking is the main reason for persistently high car fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 4. Small-displacement vehicles should not use air conditioning too aggressively: For vehicles exposed to direct sunlight, it is not advisable to turn on the air conditioning immediately after entering. First, open the windows and set the fan to a higher setting without turning on the air conditioning to expel the hot air inside the vehicle. After the vehicle has cooled down moderately, then turn on the air conditioning.

What Material is Film-Coated Cowhide?

Film-coated cowhide is also known as cowhide split leather. Leather is categorized by layers: There are top-grain and split leathers, with split leather mostly distinguished by raw materials, such as cow split and pig split. Characteristics of cowhide split leather: The reverse side is the second layer of cowhide leather, coated with a layer of PU resin on the surface, hence it is also called film-coated cowhide. Features of cowhide split leather: Split leather is obtained by slicing thick leather with a splitting machine. The top layer is used for full-grain or corrected-grain leather, while the split layer undergoes a series of processes like coating or film application to become split leather. This gives the leather surface various colors and patterns. Before film coating, the leather retains advantages like breathability and flexibility. For split leather without surface film coating, the surface is usually sueded.
