Connect the nozzle to be adjusted to the high-pressure oil pipe linked with the high-pressure oil pump, set the throttle to the maximum position, and control the speed at 40-50 pumps per minute. Use a screwdriver to adjust the nozzle until the spring is not under pressure. Observe the nozzle's oil spray while cranking the engine. When the sound of oil spray occurs, the sprayed oil begins to atomize. When you hear a crisp "hiss" sound of oil spray and see very fine oil mist being sprayed, the nozzle's oil spray pressure is approximately 11.77 MPa.

Why can't the car navigation system turn on?

The reasons why the car navigation system cannot turn on are as follows: 1. Diode damage: If the navigation system is powered but the screen remains black, it indicates that the diode on the front screen motherboard is damaged, causing excessive current and a short circuit. In this case, contact after-sales service directly. 2. Resistor burnout: If the navigation system is not powered and cannot turn on, check if the cigarette lighter is functioning normally. If not, it means the resistor under the dashboard is burned out, and the navigation system needs to be reinstalled. 3. Plug damage: If the above two issues are not present, check the plastic plug of the navigation power cord.

How Many Years Can Car Paint Be Exposed to Sunlight?

Car paint can withstand about 5 years of sun exposure, so it's essential to avoid prolonged parking under direct sunlight. Below are the hazards of exposing cars to sunlight: 1. Accelerated aging of interior materials: Interior components, typically made of plastic like the dashboard, are prone to deformation and may develop unusual noises when exposed to intense sunlight. Seats, whether fabric or leather, can harden and deteriorate in texture under high temperatures, leading to a poorer tactile experience. Therefore, it's advisable for car owners to use a car cover when parking in the sun. 2. Increased safety risks inside the vehicle: Items containing compressed gas or lithium batteries inside the car can easily explode or catch fire under high temperatures, potentially damaging internal components of the vehicle.
