2022 Spring Festival Driving Cheats: These inspection items are essential before self-driving tour! （2）

Brake system

For the inspection of the brake system, we mainly inspect the brake pads, brake discs, and brake oil. Only by regularly maintaining and maintaining the brake system can the brake system work normally and ensure driving safety. Among them, the replacement of brake oil is relatively frequent. This is because the brake oil has the characteristics of water absorption. If it is not replaced for a long time, the boiling point of the brake oil will decrease, which will bring safety hazards to driving. The brake oil is generally replaced every 2 years or 40,000 kilometers. It is worth mentioning that when purchasing brake fluids, you should buy original brake fluids or brand brake fluids as much as possible to ensure reliable quality and stable performance.

Spark plug

The spark plug is an important component of the gasoline engine ignition system. It can introduce high-voltage electricity into the combustion chamber and make it jump over the electrode gap to generate sparks, thereby igniting the combustible mixture in the cylinder. It is mainly composed of a wiring nut, an insulator, a wiring screw, a center electrode, a side electrode and a shell, and the side electrode is welded on the shell. Before traveling by car, we need to check the spark plugs. If the spark plugs are in poor working condition, it will cause problems such as difficulty in ignition, jitter, flameout, increased fuel consumption, and decreased power. At present, the mainstream spark plugs in the market include iridium alloy spark plugs, single iridium spark plugs, platinum spark plugs, etc. It is recommended that you choose iridium alloy spark plugs, which can still maintain excellent working conditions under high temperature and high pressure, and the life of iridium alloy spark plugs is Between 80,000 and 100,000 kilometers, its service life is also longer.

Air fliter

As one of the most commonly used consumables in automobiles, the air filter element has a decisive impact on the engine. The engine needs to inhale a lot of air during the working process. If the air is not filtered, the dust suspended in the air will be sucked into the cylinder, and it will accelerate. The wear of the piston and cylinder can even cause the engine to pull the cylinder, which is especially serious in a dry and sandy working environment. The air filter element can filter out dust and sand particles in the air, ensuring that sufficient and clean air enters the cylinder. Therefore, it is very necessary to check and replace the air filter in time.

The above inspection items are what we must do before traveling by car. They can not only prolong the service life of the car, but also ensure our driving safety. It can be said to kill two birds with one stone.
