What is the range of the Qiantu K50 in kilometers?

The official range of the Qiantu K50, as provided by the Ministry of Industry and Information Technology, is 380 kilometers, but the actual range is usually less than this figure. The Qiantu K50 is a pure electric vehicle among domestic cars, with dimensions of 4634mm in length, 2069mm in width, and 1253mm in height, and a wheelbase of 2650mm. The Qiantu K50 is powered by two electric motors, one on the front axle and one on the rear axle, achieving four-wheel drive. The front motor has a maximum power of 160kW and a maximum torque of 340Nm, while the rear motor also has a maximum power of 160kW and a maximum torque of 340Nm. Both the front and rear suspensions of the car use double-wishbone independent suspension.

What does the red exclamation mark on the vehicle dashboard indicate?

When a red exclamation mark appears on the vehicle dashboard, it indicates an abnormality or malfunction in the corresponding system. There are many indicator lights on the car dashboard that feature an exclamation mark, such as the tire pressure indicator, lighting fault indicator, steering system fault indicator, brake system warning light, transmission fault indicator, and windshield wiper fault indicator. There are generally three types of exclamation mark warning lights on the car dashboard: 1. A triangle with an exclamation mark inside, which is a general fault indicator; 2. A circle with parentheses and an exclamation mark inside, which is a brake system warning light; 3. A horizontal line with parentheses below and an exclamation mark inside, which is a tire pressure monitoring warning light. This light illuminates when the air pressure in one of the vehicle's tires is too low.

Do You Need to Press the Clutch When Reversing in a Manual Transmission Car?

When reversing in a manual transmission car, you need to press the clutch and use the half-clutch state to control the speed for safer reversing. The clutch is primarily used to connect or interrupt power transmission. It is necessary to press the clutch when shifting into reverse gear. After engaging the gear, you should slowly release the clutch to ensure smooth gear shifting. A manual transmission, or manual gearbox, requires the driver to manually shift gears by moving the gear lever to change the gear engagement inside the transmission, thereby altering the gear ratio to achieve speed variation. Its working principle involves using the shift fork to change the transmission ratio of the meshing gears, which in turn modifies the driving torque to suit different driving conditions.

Why does the Magotan engine shake when started?

Here are the specific reasons for the Magotan engine shaking when started: 1. Shock absorber system failure: The shock absorber system is mainly responsible for filtering the vibration of the engine during operation. If there is a problem with the shock absorber, these vibrations will be directly transmitted to the steering wheel and the interior of the car, affecting driving. When the engine is idling, turning on the electrical system in the car can also easily cause shaking. The engine increases the load due to the activation of electrical appliances, causing the idle speed to drop. To compensate for the shaking caused by the idle speed drop, the engine will automatically increase the speed. 2. Unstable oil pressure: Check whether the fuel supply pressure and intake pressure sensor are normal. If the fuel pump supply pressure is abnormal or the intake pressure sensor value is incorrect or not working properly, it will cause the car body to shake. 3. Cold start: The main reason for the car body shaking during a cold start is insufficient fuel combustion, which leads to insufficient power of the car. The ignition energy is low. When starting, when the temperature of the fuel and lubricating oil is low, it is necessary to rely on more fuel to meet the power demand. Over time, the gap between the poles of the spark plug will gradually increase, leading to a decrease in ignition energy and poor fuel atomization, which will cause the car body to shake. In addition, aging of the ignition coil, aging of the high-voltage wire of the spark plug, or leakage can also lead to a decrease in ignition energy.

How to Decelerate a Manual Transmission Car?

When decelerating a manual transmission car, you should press the brake while downshifting. First, release the accelerator to cut off the forward power, allowing the vehicle to decelerate through air resistance and ground friction. You can combine this with braking for quicker deceleration. When the vehicle is about to shake in the current gear, quickly downshift and then slowly release the clutch to shift into the appropriate gear. A manual transmission, or manual gearbox, requires the driver to manually move the gear lever to change the gear engagement inside the transmission, altering the gear ratio to achieve speed adjustment. The working principle of a manual transmission: The shift fork changes the gear ratio of the meshing gears, thereby altering the driving torque to suit different driving conditions.

Does mixing 92 and 95 octane gasoline affect the car?

If you have been using 92 octane gasoline and want to temporarily switch to 95 octane, there will be no adverse effects. However, it is not recommended to mix these two types of gasoline for extended periods, as long-term mixing of different octane ratings can impact the lifespan of the car's ignition system, fuel injectors, and spark plugs. While it is possible to mix lower octane gasoline with higher octane gasoline, the reverse (mixing higher octane with lower octane) is not advisable. Except in emergencies, avoid mixing gasoline as it may lead to insufficient vehicle power. If mixing is necessary, you can add fuel additives for cleaning afterward. Gasoline is a volatile, flammable hydrocarbon mixture liquid derived from petroleum through fractional distillation, cracking, or pyrolysis, used as fuel and appearing as a transparent liquid.
