What is the actual fuel consumption of the Volvo S90 hybrid version?

Volvo S90's officially announced combined fuel consumption is 6.7L/100km. There are currently 4 models of Volvo S90 on sale: the Momentum Luxury Edition, Momentum Sport Edition, Inscription Luxury Edition, and Excellence Luxury Edition, all with a combined fuel consumption of 6.7L/100km. The above figures are NEDC combined fuel consumption, which is the data measured under the NEDC test procedure for comprehensive driving conditions. The actual fuel consumption is higher than this value, ranging from 8.6-10.7L/100km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before encountering a red light will increase fuel consumption. The car itself: Cars with larger displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean greater power, requiring more gasoline to burn for work. Heavier cars also have higher fuel consumption because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperatures: When the engine block is cold, the gasoline injected during cold starts does not atomize easily, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer will control the engine to run at higher RPMs to warm up, which also increases fuel consumption.

What is the minimum required rest time after driving continuously for more than 4 hours?

After driving continuously for more than 4 hours, the mandatory rest period must be no less than 20 minutes. Penalties for insufficient rest time: For medium-sized or larger passenger vehicles and hazardous material transport vehicles, if driven continuously for over 4 hours without stopping to rest or with a rest period of less than 20 minutes, the penalty is 12 demerit points per violation. Consequences of not resting: If a vehicle is driven continuously for 4 hours with only a driver change (without proper rest), this constitutes fatigued driving. Such behavior significantly increases the risk of traffic accidents as it leads to delayed reactions, drowsiness, physical fatigue, and impaired ability to promptly detect road conditions and execute proper driving maneuvers.

Can a car not under my name be used for mortgage loans?

It is possible to apply for a car mortgage loan even if you are not the owner of the vehicle. Complete documentation is required: Using a vehicle under a relative's name as collateral requires all necessary documents to be complete for the application, with none missing. Generally, the required materials include the borrower's and the vehicle owner's ID cards, vehicle license, motor vehicle registration certificate, car purchase invoice, tax payment proof, and car insurance policy. Forms of mortgage loans: The borrowing form can be roughly divided into two types. First, the vehicle owner and the borrower jointly apply for the loan, becoming nominal co-borrowers who share the responsibility of loan repayment. Second, the actual fund user acts as the borrower, and the vehicle owner does not need to be present for the relevant procedures.

Will switching from 5w40 to 5w30 cause oil burning?

Switching from 5w40 to 5w30 will not cause oil burning if your car's engine allows the use of 5w30 oil. However, if your car's engine does not permit the use of 5w30 oil, oil burning may occur. Difference in viscosity: The viscosity of 5W-30 and 5w-40 oils is different, with 40 being slightly higher, meaning 40 has higher oil consumption. Difference in low-temperature performance: 5w-30 performs better at low temperatures because its viscosity is significantly better than 5w-40 under low-temperature conditions. Difference in high-temperature performance: Under high-temperature conditions, 5-40 offers better stability.

What is the Difference Between 92 and 95 Octane Gasoline?

92 octane gasoline and 95 octane gasoline differ mainly in the proportion of heptane and isooctane they contain. The specific differences are as follows: Composition Difference: 92 octane gasoline consists of 92% isooctane and 8% heptane, while 95 octane gasoline consists of 95% isooctane and 5% heptane. The primary difference lies in the purity of isooctane—the higher the purity, the stronger the gasoline's anti-knock properties. Stability Difference: 95 octane gasoline has excellent stability, but it burns more easily than 92 octane gasoline. The octane rating of 92 octane gasoline is 90%, whereas that of 95 octane gasoline is 95%. Applicable Vehicle Difference: When choosing between 92 and 95 octane gasoline, always follow the vehicle's manual. Generally, lower-end cars can use 92 octane gasoline, while higher-end cars require 95 octane gasoline to meet engine demands.

What is the reason for the sudden loud noise from the engine fan?

There are several reasons for the loud noise from the car fan: Excessive bearing wear: Check the radiator and surrounding components to see if the bearing is excessively worn. If so, replacing the bearing should solve the issue. Also, check if the fan blades are rubbing against anything. If not, the fan itself might be faulty, and replacing the fan bearing or coupling would be necessary. Fan blades: Inspect the horizontal and vertical clearance of the motor rotor shaft. If there are no issues, remove the motor and fan to check if the fan blades are deformed. Nowadays, most car repair shops typically replace the entire motor. If the problem persists, open the motor to check if the rotor is rubbing against the stator.
