What are the effects of different tire sizes on a car?

Car tire size has a significant impact on vehicle performance, primarily affecting fuel consumption, acceleration capability, and rotational inertia. Below are the detailed explanations: Fuel consumption: The influence of tires on fuel consumption is mainly reflected in wheel diameter, wheel weight, and aspect ratio. Larger vehicle rims require greater rotational inertia, which consumes more power and consequently increases fuel consumption. Acceleration capability: If the engine outputs the same amount of energy acting on the wheel torque, a smaller lever arm results in greater force. If the tire radius increases, the car's lever arm increases while the force decreases, reducing the vehicle's driving capability and thus lowering its acceleration performance. Rotational inertia: Whether the car is accelerating or decelerating, the engine's output power must overcome the wheel's inertia to directly change the vehicle's rotational speed. The larger the wheel diameter, the greater the rotational inertia that needs to be overcome.

Why can Lynk & Co only use 95 octane gasoline?

According to the official vehicle manual recommendation, Lynk & Co vehicles should use 95 octane gasoline. In addition to checking the suitable gasoline grade in the vehicle manual, Lynk & Co owners can also find this information on the fuel tank cap, which will be clearly marked. 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 gasoline grade cannot be solely determined by the compression ratio. High compression ratio engines can also be tuned to use lower octane gasoline because, besides the compression ratio, 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 Lynk & Co vehicles occasionally use the wrong gasoline grade, simply switch back to the correct grade after the current tank is used up. 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 increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means both the engine's power output and thermal efficiency will decrease, resulting in a noticeable drop in performance. For vehicles recommended to use higher octane gasoline, using lower octane gasoline can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases and it may ignite prematurely during the compression stroke. If the fuel ignites before the spark plug fires during the compression stroke, resistance will occur during the upward stroke. This resistance makes the engine run very unstably. If the knocking is mild, it may only increase noise without significant damage to the engine. However, if the knocking is severe, it indicates serious engine conditions. The vibrations not only affect driving stability but can also cause abnormal wear on the pistons and cylinders, and in severe cases, even cylinder scoring.

How many brake pads per tire?

Each tire requires 2 brake pads, meaning a total of 8 brake pads are needed per vehicle. Below are the replacement criteria for brake pads: 1. Mileage: Under normal driving conditions, front brake pads should be replaced approximately every 30,000-50,000 kilometers, while rear brake pads should be replaced every 60,000-100,000 kilometers. Once severe wear is detected, immediate replacement is necessary. 2. Wear level: Typically, new brake pads are about 1.5 centimeters thick. If the wear reaches one-third of the original thickness (less than 5 millimeters), it is recommended to replace them promptly. If a metallic scraping sound is heard during braking, this may indicate that the brake pads have worn down to their minimum thickness, causing the limit indicators on both sides of the pads to contact and scrape against the brake disc, producing unusual noises—this requires immediate replacement. If you notice that the brake pedal feels lighter than usual, or if braking becomes difficult or ineffective, it indicates severe wear and insufficient thickness of the brake pads, necessitating prompt replacement.

Why does the idle speed increase when the air conditioner is turned on?

When the air conditioner is turned on, the engine requires additional power to drive the compressor, increasing fuel injection to supplement power, which results in a higher idle speed. Below is an introduction to car air conditioner maintenance: 1. Do not arbitrarily adjust the air outlet direction: When using the air conditioner, not paying attention to adjusting the direction of the air flow is not conducive to achieving the best effect of the air conditioner. According to the principle that cold air sinks and hot air rises, the correct approach should be to point the air outlet upward when cooling and downward when heating. 2. Regularly start the air conditioner in winter: Not using the air conditioner for a long time can cause its rubber seals to age, and the lubricating oil on the internal components will dry out. Regularly starting the air conditioner allows the components to be lubricated, maintaining good condition. Therefore, it is best to start the air conditioner once a week in winter. 3. Avoid using the air conditioner for too long each time: Keeping the air conditioner on for a long time after getting in the car can cause excessive pressure on the condenser, which can damage the cooling system. Therefore, it is advisable not to use the air conditioner for too long each time. If the temperature inside the car has reached a comfortable level, you can turn off the air conditioner and turn it on again after a while. 4. Ventilate and cool down before driving in summer, then switch to internal circulation: When you first enter the car, you should open the windows for ventilation and turn on the external circulation to expel the hot air. After the temperature inside the car drops, switch to internal circulation.

Can a Manual Transmission License Drive an Automatic Transmission Car?

Manual transmission license holders are permitted to drive automatic transmission vehicles. The C1 driver's license authorizes the operation of small and micro passenger vehicles, as well as light and micro cargo vehicles, light, small, and micro special-purpose vehicles. Other vehicle types authorized under C1 include C2, C3, and C4. Below are specific details about driver's licenses: 1. Classification: The Ministry of Public Security officially issued the "Motor Vehicle Driver's License Business Work Standards," introducing a graded system for motor vehicle driver's licenses, dividing them into 15 levels: A1, A2, A3, B1, B2, C1, C2, C3, C4, D, E, F, M, N, and P. 2. Renewal Regulations: If a motor vehicle driver does not accumulate 12 penalty points in any scoring cycle during the six-year validity period of the driver's license, they can renew it for a ten-year validity period. If they do not accumulate 12 penalty points in any scoring cycle during the ten-year validity period, they can renew it for a long-term valid driver's license. 3. Content: The motor vehicle driver's license records the holder's ID number, name, gender, date of birth, permanent address, nationality, authorized (learned) vehicle type code, initial issuance date, validity period, and management records, along with the issuing authority's seal, file number, and the holder's photo. The design of the motor vehicle driver's license is stipulated by the Ministry of Public Security.
