Tire r17 indicates that the rim of the tire is 17 inches, so r18 is 18 inches. The difference between R17 and R18 tires is 2.54 centimeters. The impact of car tire size on driving: Vehicle passability: The larger the tire size on the same frame, the stronger the vehicle's passability; Vehicle smoothness: The smaller the tire size on the same frame, the better the smoothness and stability. Precautions for tire maintenance: Inflate underinflated tires promptly to maintain consistent tire pressure, otherwise it will cause rapid wear of low-pressure tires, increase driving resistance, increase fuel consumption, and may also cause directional deviation and other faults; Correct four-wheel alignment helps ensure normal vehicle control and improves tire performance. Poor wheel alignment can lead to irregular tread wear and shorten tire lifespan.

What does ECU internal fault mean?

ECU internal fault refers to a problem with the vehicle's computer. The causes of ECU internal faults include: 1. ECU self-failure, where the ECU's working area is damaged or malfunctions due to abnormal flashing, severe vibration, excessive temperature, etc., which may trigger an ECU internal fault; 2. Abnormal ECU working state, such as ECU overload caused by abnormal crankshaft signal leading to recovery lock, which will cause corresponding internal faults; 3. ECU internal faults caused by abnormal sensors or actuators, as the power supply for the sensors and actuators of the common rail system is provided by the ECU; 4. If there is a short circuit in the wiring harness or a short circuit to ground during power supply, the ECU will cut off this power supply for self-protection, thus reporting a sensor power supply voltage fault or actuator power supply fault.

Which One is the Brake and Which One is the Accelerator?

Automatic transmission cars and manual transmission cars have different positions for the brake and accelerator. The specific differences are as follows: 1. Automatic transmission cars: (1) There are only two pedals, from left to right, they are the brake and accelerator pedals. (2) The left foot controls all pedals throughout. When driving, you either press the brake or the accelerator; these two actions cannot occur simultaneously. 2. Manual transmission cars: (1) There are three pedals, from left to right, they are the clutch, brake, and accelerator pedals. (2) The left foot controls the clutch, while the right foot controls the brake and accelerator pedals. During driving, it is easy to confuse the brake and accelerator, so always pay attention to the position of your right foot to avoid pressing the accelerator instead of the brake.

Will the fuel in the car's tank evaporate if left for a day?

Gasoline in the fuel tank will evaporate, but the amount of evaporation is minimal. The reasons for evaporation are as follows: 1. If you look at the fuel gauge, it is only a 'qualitative' gauge. The scale can only indicate whether there is more or less fuel, but it does not show the actual fuel quantity. The fuel gauge may show slight variations due to changes in the car's voltage. 2. If the car is parked for an extended period, gasoline will evaporate because the fuel tank is connected to the atmosphere through valves. When the vapor pressure in the tank is high, some vapor is expelled; when the vapor pressure is low, some air is drawn in. This repeated exchange results in a reduction of gasoline evaporation. 3. Thermal expansion and contraction: Right after parking, the gasoline temperature is higher, and its volume is larger. After being parked for a while, the temperature drops, the volume contracts, and the fuel level decreases.

How to Remove Cigarette Smell from Car?

Removing cigarette smell from the car introduction: 1. First, perform a preliminary cleaning by vacuuming the carpets and emptying the ashtray; smoking in the car inevitably leaves ash, so use a vacuum cleaner to remove dust from the carpets, then clean them with a carpet cleaner. 2. You can choose to use chemical cleaners with antibacterial and odor-eliminating properties; these cleaners are highly effective at removing odors. Spray them on all visible surfaces, not just the carpets, and use a soft brush to spread the cleaner evenly. 3. Opt for natural cleaners like baking soda and activated charcoal to eliminate cigarette smell. Both baking soda and activated charcoal can absorb odors, but their application methods differ. Baking soda is harmless to humans and pets, so you can use it generously for better results. Sprinkle baking soda on all porous surfaces in the car, use a soft brush to work it in, and let it sit for several hours or even a full day—the longer, the better the effect.

How to Turn Off the Auto Start-Stop Function in Toyota Corolla?

Except for the base model with manual transmission, all other Toyota Corolla models are equipped with an auto start-stop system. The auto start-stop function is enabled by default and activates whenever the car is started. To turn it off, simply press the auto start-stop button. More details are as follows: 1. When encountering a red light or stopping for other reasons, pressing the brake pedal will typically cause the engine to shut off automatically after about two seconds. To restart the engine, release the brake and press the accelerator or gently turn the steering wheel. 2. Although the auto start-stop technology does not cause significant damage to the engine, it has some drawbacks. Frequent engine starts and stops can wear out related components, such as the starter and battery. 3. Vehicles equipped with auto start-stop systems use reinforced starters and batteries, but in practice, these components tend to experience higher failure rates compared to those in conventional vehicles without the system.
