Working Principle of Tire Pressure Monitoring in Golf 7

The working principle of tire pressure monitoring in Golf is: by utilizing ABS sensors to compare the rolling circumference and rotational speed of each wheel. If the tire pressure of one or more wheels changes, the tire pressure loss indicator in the combination instrument and infotainment system display will issue an alarm. More details about tire pressure monitoring are as follows: 1. Tire pressure monitoring involves real-time automatic monitoring of tire pressure during vehicle operation, alerting the driver to tire leaks and low pressure to ensure driving safety. 2. There are two common types: direct and indirect. The advantage of a direct tire pressure monitoring system is that each wheel is equipped with a pressure sensor and transmitter. If the tire pressure of any tire is 25% lower than the recommended cold tire pressure in the driver's manual, it will alert the driver. 3. Its warning signals are more precise, and if a tire is punctured and the pressure drops rapidly, the direct tire pressure monitoring system can provide an immediate warning. 4. The indirect tire pressure monitoring device actually uses the speed sensors on the car's ABS braking system to compare the rotation counts of the four tires. If one tire has lower pressure, its rotation count will differ from the others. By using the same sensors and signals as the ABS system, the vehicle's computer can adjust the software to establish a new function in the driving computer, warning the driver that one tire's pressure is lower compared to the other three.

What engine is used in the Porsche 918?

Porsche 918 uses a hybrid power system combining a 4.6L V8 naturally aspirated engine with dual electric motors. More details about the Porsche 918 are as follows: 1. The Porsche 918 is a plug-in hybrid vehicle launched by Porsche. This engine delivers a maximum power of 608 horsepower, while the front and rear electric motors output a maximum power of 210kW, resulting in a combined maximum power of 887 horsepower, paired with a 7-speed dual-clutch transmission. 2. The electric motors in this car only operate when the vehicle is at medium or low speeds. During high-speed driving, only the engine works, and the electric motors do not operate. 3. The battery pack has an energy density of 5.1kWh and weighs 100kg, which adds to the vehicle's weight to some extent due to the hybrid system.

Does Car Heating Consume Fuel?

Using the heating mode of a car's air conditioning system does not consume additional fuel. The car's air conditioning only consumes engine power and increases fuel consumption when operating in cooling mode, as the air conditioning compressor runs in this mode. How to Use Car Heating: After starting the car, wait about 8-15 minutes until the engine coolant reaches normal operating temperature before turning on the heating. First, use the external air circulation mode to expel cold air from the cabin for 2-3 minutes, then switch to internal air circulation. Adjust to heating mode. Some cars use a red zone to indicate heating, while others use a sun symbol. Do not turn on the air conditioning (do not activate the AC switch), as the heating system utilizes the car's own heat cycle, saving energy. Set the air conditioning to an appropriate level and adjust the air vent direction. Generally, direct warm air toward the front and footwell areas, while cold air is usually directed forward. Avoid turning on the heating immediately after starting the car in winter. When the engine is cold, the radiator temperature is still low. Turning on the heating at this time won't quickly warm up the cabin but will instead burden the engine and delay its normal temperature rise.

Why do automatic headlights fail to turn on at night?

Automatic headlights failing to turn on at night may be due to sensor or wiring issues. Here are specific explanations about why automatic headlights cannot be activated: 1. Automatic headlights use a front-mounted light sensor to detect sky brightness: When the sensor detects significant dimming of light, it will turn on the headlights. 2. When driving and the light becomes dim, the headlights will automatically turn on, and when the light becomes brighter, they will automatically turn off: There is a delay in the activation of automatic headlights, meaning the headlights will only turn on automatically within a dozen seconds after the light sensing system detects dimming. When driving through tunnels, it is necessary to manually turn on the headlights in advance. 3. Automatic headlights are very convenient to use: By turning the headlight switch to the automatic position, the automatic headlight sensor will turn the headlights on or off based on the brightness of the light.

What is the positioning of the Bora?

The Volkswagen Bora is positioned as a compact family sedan. Its body dimensions are 4663mm in length, 1815mm in width, and 1462mm in height, with a wheelbase of 2688mm. The Bora features relatively smooth side lines, with an upward-sloping waistline extending from the front fender to the taillights, combined with its overall front-low-rear-high body design, creating a strong sense of forward motion. Here are details about the Bora: 1. The latest Bora model is equipped with two engines: a 1.4-liter turbocharged engine and a 1.5-liter naturally aspirated engine. The 1.4-liter turbocharged engine delivers a maximum power of 110kW and a maximum torque of 250Nm, with the maximum power achieved at 5000 to 6000 rpm and the maximum torque at 1750 to 3000 rpm. This engine features direct fuel injection technology and uses an aluminum alloy cylinder head and block. The 1.5-liter naturally aspirated engine produces a maximum power of 83kW and a maximum torque of 145Nm, with the maximum power achieved at 6000 rpm and the maximum torque at 3900 rpm. This engine is equipped with multi-point fuel injection technology and also uses an aluminum alloy cylinder head and block. 2. The Volkswagen Bora uses a MacPherson independent suspension at the front and a torsion beam non-independent suspension at the rear.

Why does the car make abnormal noise when starting and braking?

There are several reasons for abnormal noise when starting and braking: 1. For automatic transmission cars, the noise is caused by releasing the brake too slowly, resulting in a squeaking sound when starting. 2. The brake disc and brake pads are stuck together due to rust, causing abnormal noise. This usually happens after driving in rainy weather or after the car has been parked for a long time. The brake disc and brake pads rust and stick together, and when the car is started again, abnormal noise occurs. This can be solved by applying butter or special lubricating oil to the connection between the brake pads and the brake caliper. 3. Due to low temperatures, the rubber parts of the suspension become harder, and the surfaces of the brake disc and brake pads also change, resulting in abnormal noise when starting. This will improve after the car warms up. 4. Both the brake disc and brake pads are high-wear items. Every time the brakes are applied, these two parts rub against each other, leading to natural wear over time. When the wear becomes excessive, abnormal noise will occur, so regular inspection and replacement are necessary.
