Why can't the Kaiyi C3 use 92-octane gasoline?

Kaiyi C3 should use 92-octane gasoline, as this fuel grade is recommended in the vehicle's official user manual. In addition to checking the appropriate fuel grade in the user manual, the Kaiyi C3 also indicates the recommended gasoline grade on the fuel tank cap. Typically, the fuel 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. For higher compression ratios, 98-octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the appropriate fuel grade. High compression ratio engines can also be tuned to use lower-octane gasoline due to factors like ignition timing, turbocharging technology, and Atkinson cycle technology. Generally, higher gasoline grades have higher octane ratings and better anti-knock properties. 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. Occasionally using the wrong gasoline grade in the Kaiyi C3 only requires switching back to the correct grade after consumption. However, long-term use of the wrong gasoline grade can have the following effects: Using a higher-octane gasoline in a vehicle designed for lower octane won't cause damage, but the increased octane rating alters the fuel's ignition point, leading to delayed combustion. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using lower-octane gasoline in a vehicle designed for higher octane 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 generated during the upward stroke. This resistance makes the engine run very unstably. Mild knocking only increases noise without significant engine damage, but severe knocking indicates serious engine conditions, affecting driving stability and causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring.

What are the reasons for the Southeast DX3 not responding when starting?

Southeast DX3 not responding when starting has the following reasons: 1. Battery depletion: When the car battery is depleted, the car will have difficulty starting. There are many reasons for car battery depletion, such as lack of water in the battery, battery failure, prolonged use of air conditioning, etc. Especially in winter, when temperatures are lower, the car's power consumption is significantly higher than in other seasons, and the battery's capacity decreases due to the low-temperature environment, leading to difficulty in starting the vehicle. 2. Ignition system failure: The car ignition system's function is to provide high-voltage electricity to the spark plugs at the right time to ensure the car's normal operation. If the car does not start and the battery is ruled out as the cause, it is very likely that the car's ignition system has failed. 3. Engine carbon buildup: There is too much moisture in the gasoline, poor fuel quality, or poor sealing of the valve seat rings. 4. Starter aging: If the car starter is used for too long, it will age, leading to weak starting and difficulty in starting the car.

What is the fuel tank capacity of the Jetta Spring?

The fuel tank capacity of the Jetta Spring is 55 liters. It is a compact car under the FAW-Volkswagen Jetta brand. In the same class of vehicles, the fuel tank capacity of the Nissan Sylphy is 55 liters, and the fuel tank capacity of the Volkswagen Santana is 52 liters. If the owner wants to know the remaining fuel level, they can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the pointer is close to E, it indicates that the fuel is almost empty, and when it is close to F, it indicates that the fuel level is sufficient. The maintenance of the fuel tank is as follows: Drain accumulated water and sediment from the fuel tank, and check for any oil leakage at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and steam valves, also check whether the ventilation holes are clear. The filter screen at the fuel filler inlet should be kept intact to prevent impurities from entering the fuel tank during refueling, which could block the fuel lines. The sealing gasket of the fuel filler cap should also be intact to prevent fuel from overflowing during driving.

What Causes the Jerking Sensation When Releasing the Accelerator?

Introduction to the causes of jerking sensation when releasing the accelerator in cars: 1. Engine oil passage blockage: The combustion of fuel is determined by the engine's ignition, intake, and fuel injectors, which are also the source of the engine's power. If the intake volume decreases, ignition weakens, or the amount of fuel injected reduces, the power will be insufficient, leading to a jerking sensation. 2. Jerking sensation when starting an automatic transmission car: When wanting to accelerate quickly while driving, you need to press the accelerator deeply. At this time, the automatic transmission will automatically downshift to increase the engine speed. When the speed reaches a certain level, it will upshift. After upshifting, because the speed will drop significantly, a relatively obvious jerking sensation will occur. This situation often occurs in automatic transmission models with fewer gears, such as 4-speed automatic models.

Do Rear Wheels Have Shock Absorber Top Bushings?

All car rear wheels have shock absorber top bushings. Here are the relevant details: 1. Function of Top Bushings: The top bushing material is rubber plastic, primarily serving as a buffer and shock absorber. A well-maintained top bushing gives the sensation of the car body being lifted slightly after the tires fully land when going over speed bumps, providing excellent comfort. It also reduces direct impact forces on the car when the tires encounter uneven road surfaces. 2. Replacement of Top Bushings: The shock absorber top bushing can be replaced individually. It is necessary to check for deformation, severe wear, and cracks. It is recommended to replace both shock absorbers and top bushings as a pair to achieve balanced support on both sides. Methods to determine if the shock absorber top bushing needs replacement: Without the shock absorber, the spring rebound cannot be controlled, leading to more severe bouncing when driving on rough roads. Additionally, during cornering, the up-and-down oscillation of the springs can cause loss of tire grip and tracking performance.

What Causes the Gap After Installing the Rear Bumper?

The reasons for the gap after installing the rear bumper are: the hood position is too high; the clips are aging; the bumper has come unclipped. Solutions for the gap in the front bumper: 1. Adjust the lock position: If the front hood is too high due to the lock, you can adjust the lock position on the hood to make it fit more tightly. 2. Replace the clips: There is a set of clips between the front bumper and the car. Check if the clips are tightly fastened or unclipped. If unclipped, you can visit a repair shop to replace the bumper clips. Bumper clips are very affordable, typically costing a few cents to a dollar each.
