Tire specifications are commonly represented by a set of numbers, where the first number indicates the tire section width and the latter denotes the rim diameter, measured in inches. There are various ways to represent tire specifications, with four types being most prevalent in the market: British, German, Metric, and American systems. The representation methods are as follows: 1. The British system, adopted by former British colonies, uses inches as the unit. 2. The German system is similar to the 'Metric' system, where the tire width is expressed in millimeters and also includes the aspect ratio. The inner diameter is still measured in inches, followed by the load index and speed symbol. 3. In the American system, the first letter indicates the vehicle type the tire is suitable for, the second letter represents the tire width, the third character denotes the aspect ratio, the fourth letter is the speed symbol, and the last indicates the suitable rim diameter.

What does civil air defense parking space mean?

Civil air defense parking spaces refer to parking spaces within civil air defense projects. The usage rights of these spaces are authorized by the city's civil air defense office to the construction entities of the buildings. The construction entities can transfer the usage rights of these parking spaces to individuals and organizations, but the usage period must not exceed 20 years. If national conditions require, these spaces can be compulsorily requisitioned. The latest policies regarding civil air defense parking spaces are: 1. The usage rights of civil air defense parking spaces can only be leased, not sold, and cannot be given as gifts either; 2. A 20-year lease is the maximum term allowed by contract law; 3. No individual or organization has the right to sell or transfer the property rights or usage rights of civil air defense projects, as this would harm the interests of the state and the buyers, and any contracts or agreements signed to this effect would be invalid.

How to Check the Crankshaft Position Sensor?

Here are the methods to check the crankshaft position sensor: 1. Determine by measuring voltage: Turn on the ignition switch and measure the voltage of the two signal lines to ground, which should be 1.4V. This is the preset voltage on the signal lines by the engine control unit. 2. When starting the engine, measure the signal voltage of the crankshaft position sensor, which should be close to 1.6V. 3. If there is an open or short circuit inside the sensor, signal lines, or engine control unit, the computer will be unable to receive the crankshaft position signal, and the engine will fail to start. Here is some related information about the crankshaft position sensor: 1. The function of the crankshaft position sensor is to determine the position of the crankshaft, i.e., the angle of the crankshaft. 2. The signal is calculated through the crankshaft position sensor and the camshaft position sensor, via the crankshaft position sensor.

What is the model number of the Excelle GT's brake light?

The model number of the Excelle GT's brake light is T10, and there are two brake lights and one high-mounted brake light. Here is a partial introduction to the vehicle: 1. The Excelle GT is a high-end mid-size car with body dimensions of 4587mm in length, 1798mm in width, and 1463mm in height, and a wheelbase of 2640mm. 2. In terms of power, the Excelle GT is equipped with a 2.0T turbocharged engine with a maximum power of 250 horsepower and a peak torque of 260 Nm, paired with a 6-speed manual transmission. 3. In terms of appearance, the front face of the Excelle GT does not differ much except for the eagle-eye headlights being replaced with a slightly more rounded style, but when viewed from the rear, the overall image resembles a scaled-down version of the new LaCrosse.

What is the displacement of the Ford Fiesta?

Ford New Fiesta has displacements of 1.3L, 1.5L, and 1.0T. Here is an introduction about car displacement: 1. Displacement is a specialized term in hydraulic transmission, referring to the volume of fluid inhaled or discharged per stroke or cycle. Car displacement is an important parameter for measuring a vehicle. 2. The space volume through which the piston moves from the top dead center to the bottom dead center is called the cylinder displacement; if the engine has several cylinders, the sum of the working volumes of all cylinders is called the engine displacement. It is generally expressed in liters (L). Engine displacement is one of the most important structural parameters, more representative of the engine size than the cylinder diameter and the number of cylinders. Many indicators of the engine are closely related to the displacement.

Does Engine Start-Stop Damage the Car?

Engine start-stop generally does not damage the car. Here is an introduction to engine start-stop technology: 1. Engine automatic start-stop technology is a system that can automatically control engine shutdown and ignition. Vehicles equipped with this technology will automatically shut down the engine when temporarily stopping during driving. When it's time to move forward again, the system will automatically restart the engine. Usually, the automatic start-stop function is enabled by default, but car owners can choose to turn it off if not needed. 2. The advantage of engine start-stop technology is fuel saving. Whether waiting at a red light or stuck in traffic, the engine automatic start-stop technology can automatically shut off the engine when the car stops, thereby saving fuel.

What is the normal range of tire pressure for sedans?

The tire pressure value for sedan tires is between 2.3 and 2.5. An increase in tire temperature will lead to an increase in internal tire pressure. The specific details are as follows: Methods for checking car tire pressure: Ensure the tires are "cold." This means the car has not been driven for more than 2 kilometers. Checking the pressure of cold tires ensures that the air inside has not expanded due to heat, making the pressure reading more accurate. Unscrew the cap of the tire valve stem. The valve stem is a black, pencil-sized extension near the wheel hub cover, approximately 2 to 3 centimeters long. Press the tire pressure gauge evenly onto the valve stem and record the reading on the gauge. If a hissing sound is heard, it indicates the gauge is not pressed tightly or evenly enough to obtain an accurate reading. Replace the valve stem cap. The cap does not keep air in the tire permanently, but it prevents dirt and moisture from entering the valve mechanism, which maintains the air inside the tire. Hazards of overinflated or underinflated tires: When tires are underinflated, the potential risks are even greater than when they are overinflated. Underinflation causes the tire sidewalls to become too soft, leading to dangerous heat buildup and eventually causing the tire casing to rupture. Underinflation also affects tire lifespan; when pressure is 30% below the standard, tire life can be reduced by up to 52%.
