Should Small-Displacement Turbocharged Engines Use 92 or 95 Octane Gasoline?

What octane gasoline a small-displacement turbocharged engine should use is not determined by the vehicle's class but rather by the engine's compression ratio. Generally, high-compression engines require higher-octane gasoline. For engines with a compression ratio of 10:1 or higher, it is recommended to use gasoline with an octane rating of 95 or above. Below are the differences between 95 and 92 octane gasoline: Different Octane Ratios: 92 octane gasoline consists of 92% isooctane and 8% n-heptane, while 95 octane gasoline consists of 95% isooctane and 5% n-heptane. Different Applicable Compression Ratios: 92 octane gasoline is suitable for engines with a compression ratio between 8.6 and 9.9, whereas 95 octane gasoline is suitable for engines with a compression ratio between 10.0 and 11.5. Different Anti-Knock Properties: 92 octane gasoline has poorer anti-knock properties, requiring a delayed ignition angle, which leads to faster fuel consumption. In contrast, 95 octane gasoline's stronger anti-knock properties result in slower fuel consumption.

How long should a new car run before maintenance?

New cars should undergo maintenance after running 5,000 kilometers. The maintenance inspection items include: 1. Check the car's coolant level; 2. Check the brake and clutch fluid level; 3. Check the steering oil tank oil level and whether there is oil leakage at each oil pipe interface; 4. Check the battery fluid level and windshield washer fluid tank level; 5. Check the tightness and aging of the generator, air conditioning, water pump, and power steering pump belts. The functions of car maintenance are: 1. Ensure the vehicle is in good performance condition; 2. Effectively improve the vehicle's efficiency and reduce the consumption of parts and tires; 3. Increase driving safety; 4. Avoid vehicle failures; 5. Reduce noise and environmental pollution; 6. Keep the vehicle's appearance clean and prevent vehicle damage.

What Causes the Steering Pump Noise Fault?

The causes of steering pump noise fault are: 1. Air entering the steering system; 2. Improper fit between the flow control valve hole and valve core; 3. Dirt jamming between the safety valve cone and valve seat sealing surface; 4. Non-circular sealing surface or presence of gaps. The automotive steering pump is engine-driven to convert low-pressure oil from the oil tank into high-pressure oil delivered to the steering control valve. The functions of the steering pump are: 1. As the power source of hydraulic power steering system, it reduces driver operation intensity and improves vehicle maneuverability; 2. Controls internal pressure of power steering pipelines through pressure safety valve to ensure steering system safety; 3. Regulates steering system flow through flow control valve to maintain proper steering feel during high-speed driving.
