This situation is mainly caused by a dirty fuel filter with too many impurities. When fuel is drawn through the filter to the injector, it can directly clog the injector, leading to no fuel injection or very little injection, which will damage the fuel injector. More relevant information is as follows: 1. Cleaning cycle: Fuel injectors are generally cleaned every 2 years or 50,000 to 80,000 kilometers, depending on the quality of gasoline in the vehicle's usage area. Cleaning the engine's fuel injectors is essential, as the performance of the injectors plays a fundamental role in the power output of each engine. 2. Consequences of not cleaning: Poor fuel quality can cause the injectors to malfunction, leading to severe carbon buildup in the cylinders, accelerated wear of the cylinder liners and piston rings, unstable idling, increased fuel consumption, poor acceleration, difficulty starting, and excessive emissions. In severe cases, the injectors can become completely clogged, damaging the engine.

What should be paid attention to when changing tires?

Precautions for tire replacement: 1. Consistent specifications: The replacement tires should have the same specifications as the original tires installed on the vehicle. 2. Balance: When replacing two tires at the same time, each wheel must be rebalanced after replacement to ensure that the mass of each part of the assembly is very uniform. Tires are one of the most important components of a car, and their main functions include: 1. Support: Supporting the entire weight of the vehicle, bearing the load of the car, transmitting traction and braking torque, and ensuring the adhesion between the wheels and the road surface. 2. Smoothness: Reducing and absorbing vibrations and impacts during driving, preventing severe vibrations and premature damage to car components, adapting to the high-speed performance of the vehicle, reducing driving noise, and ensuring driving safety, handling stability, comfort, and energy-saving economy.

Where is the tire pressure reset button on the Haval H7?

The Haval H7 does not have a separate tire pressure reset button. The procedure for resetting the tire pressure is as follows: Press the up button on the left side of the steering wheel to display the low tire pressure indicator reactivation, then press the (R) button on the dashboard to check if the tire pressure is normal. Finally, press the button on the right side of the steering wheel, wait for 10 seconds before turning off the button, and restart the vehicle to find the tire pressure warning has disappeared. 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 body vibration, indirectly affecting the lifespan of other components; Overstretches 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 and blowouts, leading to tire bursts.
