How to shift gears in Qoros 5s?

Shift the gear to "R" for reverse gear, and pay attention to safety when reversing. The "N" in the middle is the neutral gear, used to disconnect the engine's power connection. Shift the gear to "D" for the automatic forward gear. The "M" gear is the manual mode forward gear. After parking, remember to engage the handbrake.

What are the effects of using 95 gasoline in an engine designed for 92 gasoline?

Using 95 gasoline in a car designed for 92 gasoline has no short-term effects, but long-term use can reduce the lifespan of the vehicle's ignition system, fuel injectors, and spark plugs, and may lead to earlier major repairs due to the prolonged mixing of different gasoline grades. The appropriate gasoline grade can be determined based on the engine's compression ratio. Cars with an engine compression ratio between 8.6-9.9 should use 92 gasoline, while those with a compression ratio between 10.0-11.5 should use 95 gasoline. If the compression ratio is even higher, 98 gasoline is recommended. However, with the use of new technologies, the compression ratio alone cannot determine the gasoline grade. High compression ratio engines can be tuned to use lower-grade gasoline because factors like ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, higher gasoline grades have higher octane ratings and better anti-knock properties. 92 gasoline contains 92% isooctane and 8% n-heptane, while 95 gasoline contains 95% isooctane and 5% n-heptane. Occasionally using the wrong gasoline grade is not a problem—simply switch back to the correct grade after use. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles designed for lower-grade gasoline, using higher-grade gasoline will not cause damage, but the increased octane rating can alter the fuel's ignition point, leading to delayed combustion. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. For vehicles designed for higher-grade gasoline, using lower-grade gasoline can cause engine knocking. The significantly lower octane rating lowers the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance is created during the upward stroke. This resistance makes the engine run very unstable. Mild knocking only increases noise without obvious damage, but severe knocking indicates serious engine issues, affecting driving stability and causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring. Considerations when choosing gasoline: Select gasoline with appropriate volatility based on the ambient temperature. Gasoline with good volatility ensures easy cold starts and balanced engine warm-up. However, excessive volatility can cause vapor lock in fuel lines, preventing the fuel pump from functioning properly and leading to engine stalling. Choose gasoline based on its lead content.

How to Turn Off the Qoros 5?

Press the brake to ensure the vehicle is stationary, shift the gear to N, and engage the handbrake. Shift to P, release the brake, and turn off any unnecessary electrical devices in the car. Check that the gear is in P, all unnecessary electrical devices are turned off, and the steering wheel is straightened. Turn the key counterclockwise to the end or press the start-stop button once to switch the ignition to the OFF position.

How to Remove the Speed Limiter on the Liexing 125?

With the ignition switch turned off, rotate the right handlebar grip to the maximum position while holding the brake lever fully. Then, with your left hand, turn on the ignition switch while holding the left brake lever, and release the right handlebar grip and right brake lever with your right hand. After releasing the handlebar grip completely, quickly rotate the right handlebar grip to the maximum position and release it twice in succession. Ensure that the actions of holding the brake lever with your left hand and rotating the handlebar grip with your right hand are completed within 5 seconds.
