Is a Tire Pressure of 290 Normal in Summer?

1 Answers

Summer tire pressure of 290 is not normal. According to the international GBT2978-2008 standard requirements, the standard tire pressure should be between 2.4-2.5 bar. 290 is higher than the maximum value of standard tire pressure, so it is not normal. Hazards of excessive tire pressure: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern of the tire, shortening its lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches and deforms the tire cords, reducing tire elasticity and increasing the load on the vehicle during driving; Decreases puncture resistance. When encountering sharp objects like nails or glass on the road, they can easily penetrate the tire, causing internal cracks or blowouts, leading to tire bursts.

How to Solve the Engine Noise Issue in Baojun 510?

Here are specific methods to eliminate engine noise in Baojun 510: 1. Reduce compressor stage load, increase axial clearance between rotor and stator, change blade count, remove inlet guide vanes, and select appropriate compressor speed to lower compressor noise. 2. Decrease exhaust velocity to reduce jet noise, such as increasing bypass ratio in turbofan engines to lower exhaust speed. 3. Use corrugated and lobed nozzles to increase contact area between jet flow and external airflow, thereby reducing jet mixing noise. 4. Apply sound-absorbing liner structures on engine pipe walls. In aero-engine noise research, noise can be viewed as composed of monopole, dipole, and quadrupole noise sources. Monopole noise, caused by mass fluctuations and structural vibrations, commonly occurs in engine intakes and exhaust nozzles, predominantly at low frequencies.

What Does Remote Car Start Mean?

Remote car start refers to the function of starting a vehicle's engine remotely without the need for someone to enter the car, by sending a signal through a key fob or a smartphone. The remote range of the key fob is typically over 50 meters, while smartphone control operates via a network, meaning distance is virtually unlimited. Remote start is very common abroad, especially in winter, allowing users to preheat the engine or turn on the air conditioning in advance, ensuring a comfortable temperature upon entering the vehicle. The remote start of the engine is no different from manual ignition, as both methods use the electric motor to start the engine. Therefore, there's no need to worry about mechanical wear on the heater or potential malfunctions. To prevent the engine from running indefinitely, it usually operates for about ten minutes before automatically shutting down if no further commands are received.
