AT transmission works by having two turbine blades assembled in a space filled with hydraulic oil, connected to the power input and output ends respectively. The turbine at the power input end generates a strong vortex to drive the turbine at the output end, thereby achieving power transmission. More details are as follows: 1. The core of an automatic transmission lies in achieving automatic gear shifting. Automatic gear shifting means that during driving, the driver presses the accelerator pedal as needed, and the automatic transmission can automatically shift into different gears based on engine load and the vehicle's operating conditions. 2. The advantages of AT include: using a clutch for shifting, enabling uninterrupted power shifting with smooth transitions; employing a torque converter, which can cushion engine shocks and vibrations, providing good ride comfort; due to the use of a torque converter, the vehicle has excellent low-speed driving capability; and it is widely applicable to various vehicle models.

What is the size of the Jetour X70 spare tire?

Jetour X70 spare tire is 16 inches. Below is the relevant introduction about the Jetour X70 spare tire: 1. The Jetour X70 spare tire is non-full size and is mounted under the rear chassis, which helps save interior space. The spare tire layout is the same for both 5-seater and 6/7-seater models. However, since the 5-seater model does not have a third row of seats, there are four large storage compartments under the trunk cover. 2. The high-end models are equipped with Jinyu tires, YS82+ series, with a size of 255/45R20. 3. Removing the Jetour X70 spare tire is very simple. Just use the included tools to rotate it counterclockwise and take it off.

What are the reasons why a Tiguan car won't start?

Tiguan car won't start for the following reasons: 1. Fuel depletion. If the fuel gauge shows below the red line, the car naturally won't start. 2. Dead battery. Power loss due to reasons like leaving headlights on for too long or an expired battery lifespan. It's generally recommended to replace the battery every 2 years. Additionally, installing xenon headlights, high-power audio systems, or DVD players can also cause vehicle circuit failures. 3. Incorrect gear position. When starting an automatic transmission car, the gear must be in P (Park) or N (Neutral). If it's in R (Reverse) or D (Drive), the car won't start. Some manual transmission cars also won't start if the clutch isn't depressed.

Where is the OBD interface of the X-Trail located?

The OBD interface of the X-Trail is located under the steering wheel. Below is some relevant information about the X-Trail's OBD: 1. The OBD interface of the X-Trail is positioned under the steering wheel, specifically a bit below the driver's seat, about 5cm to the right of the fuse box, with the opening facing downward, requiring you to position your head near the foot mat area. 2. OBD stands for On-Board Diagnostics, which translates to the vehicle's onboard self-diagnostic system. This system continuously monitors the engine's electronic control system and other functional modules of the vehicle while it is running. If any abnormal conditions are detected, it identifies specific faults based on predefined algorithms and stores them as Diagnostic Trouble Codes (DTCs) in the system's memory. 3. The useful information obtained from the system's self-diagnosis can assist in vehicle maintenance and repairs. Technicians can use the manufacturer's specialized equipment to read the fault codes, enabling quick fault identification, which facilitates vehicle repairs and reduces manual diagnostic time.

Is the CT5 equipped with a longitudinal engine?

CT5 is equipped with a longitudinal engine. Below are the relevant details about the CT5's longitudinal engine: 1. The CT5 features a longitudinal engine with rear-wheel drive. This longitudinal rear-wheel-drive configuration is a driving style that offers considerable enjoyment, and many car enthusiasts particularly favor vehicles with this setup. 2. The CT5's engine is front-mounted. To achieve rear-wheel drive with a front-mounted engine, it must be arranged longitudinally. 3. The CT5 is powered by a 2.0-liter turbocharged engine across all models. This engine delivers 241 horsepower and a maximum torque of 350 Nm, with a maximum power output at 5,000 rpm and peak torque available between 1,500 and 4,000 rpm. It incorporates variable valve management technology, direct fuel injection, and an aluminum alloy cylinder head and block. 4. The engine is paired with a 10-speed automatic transmission. The CT5 utilizes a MacPherson strut front suspension and a multi-link independent rear suspension. The multi-link setup enhances wheel contact with the road, thereby improving traction and handling.

Should a Chevrolet Use 92 or 95 Octane Gasoline?

According to the official vehicle manual recommendation, Chevrolet should use 92 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, you can also find it marked on the fuel tank cap. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95 octane gasoline. However, with the application of new technologies, the gasoline grade can no longer be determined solely by the compression ratio. High compression ratio engines can also be tuned to use lower octane gasoline. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong gasoline grade in a Chevrolet, simply switch back to the correct grade after the current tank is used up. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended to use lower octane gasoline, using higher octane gasoline will not cause damage, but the increase in octane number will alter the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is too low, the gasoline will ignite prematurely during the compression stroke before the spark plug fires. This premature ignition creates resistance during the upward stroke. Such resistance makes the engine run very unstably. If the knocking is mild, it only increases noise without significant damage to the engine. However, if the knocking is severe, it indicates serious engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.
