Should the MG 5 use 92 or 95 octane gasoline?

According to the official vehicle manual recommendation, the MG 5 should use 92 octane gasoline. In addition to checking the appropriate 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 compression ratio alone cannot determine the gasoline grade, as high compression ratio engines can also be tuned to use lower octane gasoline. 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 the MG 5 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after consumption. 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 increased octane number may alter the fuel's ignition point, leading to delayed combustion in the engine. This results in reduced engine power and thermal efficiency, manifesting as poorer performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. The significantly lower octane number reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, resistance will develop during the upward stroke. This resistance leads to unstable engine operation. If the knocking is mild, it may only increase noise without significant engine damage. However, noticeable knocking indicates severe engine conditions, affecting not only driving stability but also causing abnormal wear on pistons and cylinders, and in severe cases, cylinder scoring.

What brand is the transmission of the Changan UNI-K?

"The transmission brand of the Changan UNI-K is Aisin. Established in 1969, Aisin is a world-renowned professional research, development, and manufacturer of automotive automatic transmissions. In the field of automotive automatic transmissions, Aisin's products hold the highest market share globally. The Changan UNI-K is equipped with an Aisin 8AT automatic manual transmission. The automatic manual transmission is essentially a traditional AT or CVT transmission with the addition of manual shifting functionality. The purpose of the automatic manual transmission is to enhance the driving pleasure of automatic vehicles. When using the transmission of the Changan UNI-K in daily driving, the following points should be noted: Do not delay changing the transmission oil for extended periods. Prolonged failure to change the transmission oil can lead to damage to internal components such as bearings and the housing. Avoid prolonged coasting in neutral. While driving manual transmission vehicles, many experienced drivers tend to coast in neutral, but for automatic transmission vehicles, coasting in neutral can cause the automatic transmission to overheat, and shifting back into D gear may result in some impact. Never shift into D/R gear before the vehicle comes to a complete stop. Many drivers, to demonstrate their "smooth" operation, shift directly into reverse gear before the vehicle stops completely, which can cause significant damage to the transmission gears and may lead to gear grinding faults over time. Avoid frequently climbing steep slopes in D gear. When facing steep slopes, automatic transmission vehicles often overheat due to high load or shift prematurely, resulting in insufficient climbing power. In such cases, manual mode can be used to limit the gear to low speed or sport mode to protect the transmission. Do not tow the vehicle over long distances. If an automatic transmission vehicle breaks down, it should be moved onto a flatbed tow truck in N gear, rather than being towed directly using a tow rope or similar methods."

What are the tips for controlling the clutch in Subject 2?

The key to controlling the clutch in Subject 2 is to press down quickly and lift slowly, pausing slightly midway to find the contact point; maintain a gentle pressure above the contact point and lift the pedal smoothly for coordinated movement. Here is some relevant information about the clutch: 1. How the clutch works: The clutch operates by depressing or releasing the clutch pedal, temporarily separating or gradually engaging the engine with the transmission to cut off or transmit the engine's power to the gearbox. 2. The working states of the clutch: The clutch has three working states: disengaged when the clutch is fully depressed, fully engaged when the clutch is not depressed, and semi-engaged when the clutch is partially depressed. Semi-engagement is the decisive factor in whether the engine's kinetic energy is transmitted to the wheels. Many people experience unstable speeds or even stalling because they fail to accurately master the semi-engaged state, either pressing or releasing the clutch too much.

Why Keep Lightly Pressing the Brake at Red Lights?

The reasons for keeping the brake lightly pressed at red lights are as follows: 1. Prevent Rolling: For automatic transmission vehicles, rolling is less likely to occur. However, for manual transmission vehicles, when the light changes from red to green, operational errors can easily cause the vehicle to roll forward or backward. If the driver fails to press the brake in time, it may lead to a "close encounter" with the vehicle in front, causing unnecessary traffic congestion and potential injuries. Keeping the brake lightly pressed can effectively prevent rolling, as pressing the brake fully will immobilize the vehicle. 2. Maintain Vehicle Stability: Frequent gear shifting increases operational difficulty and can lead to vehicle instability, causing abnormal noises and vibrations that affect the riding experience. Lightly pressing the brake with the right foot avoids these issues and helps maintain vehicle stability. 3. Save Time: At red lights, most novice drivers park by "shifting to neutral + pulling the handbrake." While this method is not wrong, when the light turns green, the driver needs to shift gears and release the handbrake before starting the vehicle, which is time-consuming. Some drivers might even forget to release the handbrake, causing abnormal noises and affecting the vehicle's lifespan. Lightly pressing the brake during the wait can save time. Once the light turns green, the driver only needs to shift gears and release the brake to start moving. 4. Increase Traffic Flow: The duration of green lights varies across different road sections. Some sections have green lights lasting over 60 seconds, while others may only last 20-30 seconds or even less. To pass through the green light quickly, every second counts. Keeping the gear in first and lightly pressing the brake can effectively increase traffic flow. As soon as the driver sees the green light, releasing the brake, pressing the accelerator, and shifting gears allows for smooth passage.
