What does 91h on a tire mean?

Tire 91h indicates that the maximum load capacity of a single tire is 615Kg, and the maximum speed it can withstand under the specified load is 210KM/h. Here are the relevant details: 1. 91 is called the load index, and the maximum load capacity of 615Kg can be determined by referring to the tire load index chart. 2. H is called the speed rating. Additional information: Whether it's the speed rating or the load index, during daily driving, you should operate within the specified limits of the speed rating or load index. Otherwise, there could be significant safety hazards. Additionally, when replacing tires, it's important to note that you should not mix tires of different types, models, or tire structures.

Is the Teana clutch a dry type?

Teana clutch is a dry clutch. The clutch plate is a composite material primarily functioning through friction while also meeting structural performance requirements. Automotive friction materials are mainly used to manufacture brake friction plates and clutch plates. The working principle of the clutch is as follows: 1. Disengaged when depressing the clutch pedal: When starting the vehicle, the driver depresses the clutch pedal, which pulls the pressure plate backward, separating it from the friction plate. At this point, the pressure plate does not contact the flywheel, eliminating relative friction. 2. Fully engaged when not depressing the clutch pedal: During normal driving, the pressure plate tightly presses against the flywheel's friction plate, achieving maximum friction between them. The input and output shafts maintain relative static friction with identical rotational speeds. 3. Partially engaged during semi-engagement: The friction between the pressure plate and friction plate is less than in full engagement. The pressure plate and flywheel's friction plate enter a sliding friction state, where the flywheel's speed exceeds the output shaft's speed, transmitting partial power from the flywheel to the transmission. In this state, the engine and drive wheels establish a flexible connection.

Which Gear Should a Manual Transmission Car Be in When Going Downhill?

When parking a manual transmission car downhill, engage the reverse gear to prevent forward sliding. When starting, first press the clutch, shift to neutral, start the vehicle, and then shift to the starting gear. The steps for starting a manual transmission car are: 1. Sit properly in the car; 2. Start the car; 3. Press the clutch; 4. Engage the 1st gear; 5. Slowly release the clutch; 6. Gently press the accelerator; 7. Fully release the clutch to complete the car's start. The reasons for a manual transmission car stalling after ignition are: 1. Use of substandard or poor-quality fuel; 2. Issues with the car's engine or fuel system; 3. Engine carbon buildup; 4. Excessive dirt on the idle motor valve core and throttle seat; 5. Releasing the clutch too quickly when starting.

What Causes Rapid Loss of Car Coolant?

The main reasons for rapid consumption of engine coolant are: 1. Poor cooling system design. 2. Inefficient circulation leading to fast consumption; When adding coolant, it should be done after the engine temperature has cooled down. During the process, start the engine and gently press the accelerator to expel air from the system. Add the coolant slowly to ensure proper filling. If necessary, follow the manual's instructions to bleed the cooling system. 3. Leakage; Usually, traces can be seen at the leakage points. 4. Coolant entering the cylinder and being burned or entering the oil pan. In mild cases, there will be no water in the oil pan, while in more severe cases, water will be present, and the engine will run unsteadily. Do not immediately assume the issue is with the cylinder head gasket—a damaged intake manifold gasket can also cause coolant to enter the cylinder, as some engines have coolant passages in the intake manifold. If the coolant is being burned significantly, the engine exhaust pipe will emit water and white smoke.

What is the correct way to depress the clutch?

The correct method for depressing the clutch is as follows: 1. Starting on flat ground. After pressing the clutch and shifting gears, when the car's speed hasn't picked up yet, the clutch should be released slowly. Releasing the clutch too quickly can cause the engine to stall. You can wait until the clutch is fully released before applying the throttle, as coordinating the throttle and clutch requires relatively high skill. 2. Starting on a slope. Hill starts are one of the most challenging aspects of driving. Even slowly releasing the clutch can sometimes cause the engine to stall, let alone releasing it immediately. The correct operation should be to slowly release the clutch until the engine starts to vibrate, then release the brake pedal and immediately step on the accelerator. If you're not proficient, you can also use the handbrake to ensure driving safety. 3. Shifting from first to second and second to third gears requires slow clutch release, while shifting from third to fourth and fourth to fifth gears allows for quicker release. When the car speed is low, the clutch should be released slowly to avoid strong jerking sensations. Once the speed increases, quickly releasing the clutch will hardly cause any noticeable jerking. In summary, when shifting between first, second, and third gears (low-speed gears), slow release is necessary to prevent stalling and jerking; when shifting between third, fourth, and fifth gears (high-speed gears), a slightly quicker release is acceptable.

How to Turn Off the Engine Start-Stop?

To deactivate the engine start-stop function: When starting the engine, press the auto start-stop deactivation button while simultaneously turning off the ignition and removing the key. Upon restarting the vehicle, the engine start-stop will be completely disabled. Scenarios requiring auto start-stop deactivation: 1. When driving on steep slopes, avoid enabling auto start-stop. Although the engine pause is brief, it may lead to insufficient brake assistance during hill climbs. 2. In extremely hot southern weather with air conditioning operating at full capacity, disabling this function is recommended. The vehicle's electrical system may lack sufficient power to sustain AC operation during engine shutdown, compromising passenger comfort.
