Global trade disruption analysis

Engine startup process (engine start: from shutdown to roar) When we start the car,Global trade disruption analysis the first thing we need to do is to open the door of the car, sit in the driver's seat, insert the key, open the door, and then press the brake pedal. Next, we can press the engine start button to start the car engine. In the process of starting the car's engine, it mainly involves the following three steps: 1. Start preparation 2. Ignition 3. Engine start 1. Start-up preparation Start-up preparation is the first step to start the engine. This step is to prepare all the necessary equipment to ensure that the engine can start normally. In order to start the car engine, the following equipment needs to be prepared: - Vehicle battery: Vehicle start battery is one of the most important components in the process of starting the car engine.If the battery is underpowered, the start of the car may fail. - Ignition switch: This is one of the key steps to start the car engine. When igniting, the switch will guide the current into the engine to help the engine start. Before ignition, you can adjust the igniter to ensure that the car can start smoothly. - Fuel pump: Fuel pump is a device that provides fuel for the car. The function of this device is to transport fuel from the fuel tank to the engine to help the engine start. - Air filter: Air filter is the last device needed to start the car engine. The function of this filter is to prevent dirt and impurities from entering the engine, thus improving the operating efficiency of the car engine. Two. Ignition After all the necessary equipment is ready, the next step is to ignite. In the process of ignition, we need to press the ignition button of the car engine to transmit the current into the engine and prepare the fire pin. The fire pin is a device that is responsible for extinguishing the sparks generated by ignition. At the time of ignition, if the spark is not extinguished, an explosion may occur during the start-up process, resulting in engine damage. 3. Engine start After the ignition process is completed, we can start the engine. During the start-up process, we need to provide fuel to the engine and inject a certain amount of air into the engine to help the engine emit exhaust gas. When the engine starts, we can hear the roar of the engine. At this time, we need to observe the dashboard of the car to ensure that all indicators of the car are normal, such as fuel, water temperature, oil temperature, etc., to ensure safe driving. During the engine start-up process, if the car does notWhen starting, you can try to check whether the battery power is sufficient, whether the fuel is sufficient, whether the ignition is normal, whether the air filter is clean, whether the fire pin is normal, etc., so as to find the crux of the problem and solve the problem in a timely manner. In a word, it is necessary to be prepared during the engine start-up process to ensure that the engine is ignited and started normally. At the same time, it is necessary to observe the indicators of the car dashboard at all times to ensure the safe driving of the car.
