Can a Tire with a Nail Still Be Used?

What is the situation with severe engine shaking in the Buick Excelle?

Detailed information about severe engine shaking in the Buick Excelle is as follows: 1. Engine misfire. Engine misfire mainly refers to one or more cylinders of the engine not working properly. Common symptoms include: intermittent exhaust gas flow with noticeable shaking of the exhaust pipe, where the engine vibration can be clearly felt, sometimes accompanied by a sputtering sound. This is mostly related to ignition coil failure. 2. Aging or loosening of engine mounts. Engine mounts are rubber blocks placed between the engine and the frame. Their function is to reduce the vibration and shock generated during engine operation and to secure the engine in place. Once these mounts age or loosen, the engine shaking will become abnormally severe. It is recommended to replace the engine mounts, after which the effect will be significantly reduced. 3. Carbon buildup issues. Cars inevitably face carbon buildup problems, which include cylinder carbon buildup, throttle carbon buildup, spark plug carbon buildup, and intake carbon buildup, among others. When there is excessive carbon buildup inside the engine, the car's ignition energy, intake efficiency, and air-fuel mixture ratio will be affected, leading to unstable power output and shaking during idling and acceleration. It is recommended to perform an engine cleaning service at a 4S shop. 4. Fuel system failure. Using incompatible fuel grades (e.g., using 90 octane instead of 93 octane) can reduce the car's output power and performance; or if the fuel tank vent is blocked, the fuel tank switch, fuel filter, or the fuel line between the fuel tank and the carburetor is partially blocked, the required fuel supply cannot be met, leading to a lean air-fuel mixture and engine shaking. It is recommended to use the fuel grade specified by the manufacturer and perform regular maintenance.

What are the body dimensions of the Porsche 718?

The length, width, and height of the Porsche 718 are 4379mm, 1801mm, and 1276mm respectively, which are official data. The length of the Porsche 718 refers to the distance between two vertical planes perpendicular to the vehicle's longitudinal symmetry plane and touching the outermost protruding parts at the front and rear of the vehicle; the width refers to the distance between two planes parallel to the vehicle's longitudinal symmetry plane and touching the outermost rigid fixed protruding parts on both sides of the vehicle; the height refers to the distance between the highest point of the vehicle and the supporting plane of the vehicle. The Porsche 718 uses two types of engines: a 2.0-liter turbocharged engine and a 2.5-liter turbocharged engine. The 2.0-liter turbocharged engine has a maximum torque of 300 horsepower and 380 Nm; the maximum torque speed of this engine is between 2050 and 4500 rpm, and the maximum power speed is 6500 rpm. This engine is equipped with direct fuel injection technology and uses an aluminum alloy cylinder head and block. It is paired with a 7-speed dual-clutch transmission. The 2.5-liter turbocharged engine in the Porsche 718 has a maximum torque of 366 horsepower and 430 Nm. The maximum torque speed of this engine is between 1900 and 5000 rpm, and the maximum power speed is 6500 rpm. This engine is also equipped with direct fuel injection technology and uses an aluminum alloy cylinder head and block. There are relevant national regulations regarding vehicle dimensions. According to the national standard "GB1589-89," the total width of a vehicle does not include side mirrors. The limitation on vehicle width is to provide sufficient lateral clearance for overtaking between adjacent lanes. This means that, according to national standards, the significance of vehicle width data is to ensure sufficient space during overtaking, preventing accidents due to excessive width or situations where road markings are narrower than the vehicle's width. Additionally, national regulations stipulate that the total width of a vehicle must not exceed 2.5 meters to comply with the usage requirements of public roads.

Where is the rearview mirror heating switch on the Civic?

The rearview mirror heating button on the Civic is located below the central control screen. There are two knobs below the central control screen. In the middle of the knobs, there is a row of buttons, and the rearview mirror heating button is the rightmost one. Rearview mirror heating is generally suitable for rainy or snowy weather. When the rearview mirror is heated, the heater behind the mirror quickly warms the mirror surface, gradually removing rainwater or fog from the mirror, eliminating the need for the driver to frequently wipe the mirror manually, thereby reducing driving hazards. How to use the rearview mirror heating function: There are generally two ways to activate the rearview mirror heating function. One is combined with the electric rearview mirror adjustment function key—simply rotate the knob to activate it. The other is located on the air conditioning control panel—pressing the heating button will activate it. There is no need to adjust the angle manually, as there is an adjustment button on the driver's side. Principle of the rearview mirror heating function: After pressing the button, the electric heater behind the rearview mirror glass will rapidly heat up to a fixed temperature within a few minutes, usually between 35-60 degrees. The heat will dissipate from the left and right rearview mirrors. At the same time, as the temperature rises and evaporates, water droplets on the mirror surface will become smaller, and fog will gradually disappear, thereby heating the mirror and removing frost. If the rain is particularly heavy, its effect will diminish and become less noticeable. Precautions for using the rearview mirror heating function: The principle of rearview mirror heating involves adding electric heating wires to the rearview mirror. These wires consume a significant amount of electricity. When using the rearview mirror heating function, ensure the car is in an active state. Avoid activating the rearview mirror heating function while the car is stationary to prevent draining the car battery, which could lead to insufficient power for starting the car. Other methods for defogging rearview mirrors include: Opening windows for convection: Crack open the windows on both sides to allow air convection between the inside and outside of the car, reducing the temperature difference and causing the fog to gradually disappear. Adjusting the car's air conditioning to the appropriate setting can also use warm air from the AC to defog the mirrors.

What is the difference between a 6-speed and a 5-speed car?

There are several differences between 6-speed and 5-speed cars: 1. Transmission ratio difference: When using the same engine, a 6-speed transmission allows for more refined gear ratio tuning compared to a 5-speed transmission, with smaller transmission ratio differences between gears. This results in smoother driving with less noticeable gear shifts. 2. Smoothness aspect: The increasing number of gears in cars is due to manufacturers' technical improvements and upgrades to enhance transmission efficiency and reduce carbon emissions. Generally, more gears mean better smoothness, so a 6-speed car typically offers better smoothness than a 5-speed car.
