What does Porsche PASM mean?

Porsche PASM refers to Porsche Active Suspension Management, an electronic damping control system. The Porsche PASM system has the function of controlling body movement. When the inertia during braking or cornering causes spring deformation, the active suspension system generates a force that counteracts the inertial force, reducing changes in body position. Automotive active suspension systems can be divided into three major categories based on control type: hydraulic-controlled suspension systems, air suspension systems, and electromagnetic induction suspension systems. Porsche PASM belongs to the active air suspension system category. Porsche PASM can variably adjust damping force according to road conditions and the driver's driving style, placing more emphasis on sports performance compared to other manufacturers' active suspension systems. For example, if the driver's actions are more aggressive, frequently performing full-throttle starts and hard braking, the Porsche PASM system will automatically control the lift and dive phenomena during acceleration and braking. When driving at high speeds on rough roads, Porsche PASM also actively reduces body sway to improve stability.

Why does the car overheat after driving for a while?

Here are the reasons why a car overheats after driving for a while: 1. Severe coolant deficiency: If the owner fails to promptly inspect and replenish the coolant, it can easily lead to engine overheating. If the engine becomes very hot after driving for a while, it may not just be a lack of coolant; it could likely be due to a leak in the radiator pipes, resulting in a severe coolant shortage. 2. Water pump failure: After the water pump fails, the water that conducts heat for the engine cannot circulate and renew in time. Then, after the engine runs for a period of time, the water temperature will rise rapidly, and the water temperature warning light on the dashboard will also illuminate. 3. Cooling fan failure: Damage to the cooling fan or a short circuit in the wiring can cause the fan to malfunction or operate at a slow speed. This prevents the engine's heat from dissipating, leading to an increase in engine temperature. Upon opening the engine compartment, you can naturally feel a significant amount of heat.

What is the tire size?

Generally, base models use smaller tires, but the aspect ratio of the tires will also increase, resulting in minimal overall difference. High-end models use larger tires, which increase ground clearance and improve comfort, but there is no significant difference in handling. More details about tires are as follows: 1. Introduction one: Tires are a crucial component in vehicle operation, and their performance directly affects the safety, stability, and fuel efficiency of the vehicle. Nowadays, radial tires are commonly used in cars. The tire's cord layers are arranged parallel to each other, resembling the Earth's meridians, hence the name radial tire. 2. Introduction two: Compared to conventional bias-ply tires, radial tires are characterized by greater elasticity, better wear resistance, which can extend tire life by 30% to 50%, lower rolling resistance, reducing fuel consumption by about 8%, better grip and cushioning performance, and higher load capacity. Therefore, the use of radial tires is becoming increasingly widespread.

How long does it take for the water temperature to normalize after starting the car?

How long it takes for the water temperature to normalize after starting the car depends on the season and humidity conditions. In winter when the weather is colder, it takes about 5 to 10 minutes if the temperature is below 5 degrees Celsius, and 1 to 2 minutes if it's above 5 degrees. If the engine is too cold, the internal oil becomes less lubricating and cannot effectively lubricate the engine. Starting the car in this condition will cause wear on the engine cylinders, shortening the engine's lifespan. The correct method to allow the car's water temperature to reach normal levels is to drive slowly at low speeds. Avoid high RPMs and maintain a low speed, keeping the engine speed below 3000 RPM, generally around 2000 RPM. Otherwise, the severe wear on the engine and transmission may be irreversible. Once the engine temperature rises to the normal operating temperature (which usually takes about 3 to 5 minutes), you can resume normal driving.

Where is the motorcycle three-way catalytic converter located?

Motorcycle three-way catalytic converters are located inside the exhaust pipe. Here's some information about three-way catalytic converters: 1. Installation regulations: According to the regulations of the Ministry of Environmental Protection of the People's Republic of China, not every motorcycle is equipped with one. 2. Three-way catalytic converter: It is the most important external purification device installed in the exhaust system, which can convert harmful gases such as CO, HC, and NOx in the exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. When high-temperature exhaust passes through the purification device, the purifying agent in the three-way catalytic converter enhances the activity of CO, HC, and NOx, promoting certain oxidation-reduction chemical reactions. CO is oxidized into colorless, non-toxic carbon dioxide gas at high temperatures; HC compounds are oxidized into water (H2O) and carbon dioxide; NOx is reduced into nitrogen and oxygen. These three harmful gases are transformed into harmless gases, thereby purifying the vehicle's exhaust emissions.

How to Repair a Crack in Glass?

Fill the crack with liquid resin, clean the gap, and use a vacuum injector to remove the air inside the glass crack. Then, fill it with liquid resin. After repeatedly extracting and pressing, use a UV lamp to irradiate for two minutes in all directions (up, down, left, and right) to allow the repair solution to solidify. Next, apply a high-concentration repair agent to the crack, cover it with a glass piece, and dry it. Finally, use a blade to level the surface, apply a polishing agent, and polish it with a cloth. Below is relevant information about automotive glass: 1. Manufacturing Process: Automotive glass is made by heating the glass in a furnace to near its softening temperature, then quickly transferring it to air grids with different cooling intensities for uneven cooling, creating varying stress levels between the main viewing area and the peripheral areas. 2. Types: It is divided into laminated glass and tempered glass. Laminated glass is a glass product made by bonding two or more layers of glass with one or more layers of transparent adhesive material. Tempered glass includes physical tempering and chemical tempering, with the commonly referred tempered glass being physically tempered.
