What is the function of the ignition system?

1 Answers

The function of the ignition system is to generate a sufficiently energetic electric spark between the electrodes of the spark plug in a timely manner according to the working sequence of the cylinders. In a gasoline engine, when the compression is near the top dead center, the combustible mixture is ignited by the spark plug, thereby burning to perform external work. For this reason, spark plugs are installed in the combustion chambers of gasoline engines. The ignition system is an important component of gasoline engines, and its performance significantly affects the engine's power, fuel consumption, and exhaust emissions. All the equipment capable of generating an electric spark between the electrodes of the spark plug is referred to as the engine's "ignition system," which consists of components such as the battery, generator, distributor, ignition coil, and spark plug.

What are the classifications of transmissions?

Transmission classifications: manual transmission, automatic transmission, automated manual transmission, continuously variable transmission. Detailed introductions are as follows: Manual transmission: When shifting gears with a manual transmission, you need to depress the clutch, then move the gear lever, and finally release the clutch to complete the gear shift. Automatic transmission: A good automatic transmission shifts responsively with reasonable logic, achieving excellent fuel consumption results. Compared to manual transmissions, automatic transmissions are more convenient to operate, generally requiring no gear changes while driving. However, there is some loss in transmission efficiency, resulting in higher fuel consumption than manual transmissions. Automated manual transmission: An automated manual transmission is essentially a manual transmission with an added control computer, typically with 5 speeds and lacking D and P gears. Continuously variable transmission: A continuously variable transmission can achieve continuous changes in the transmission ratio, thereby achieving the best match between the transmission system and the engine's operating conditions. Its advantages include smooth operation, no jerking sensation, and strong driving comfort. The disadvantages are a relatively poor ability to withstand torque and slower response to speed changes.

How long does Beidou fatigue driving record last?

Beidou fatigue driving records are retained for one year. During daily vehicle operation, fatigue driving inspections are strictly enforced. When a vehicle has been continuously driven for four hours, it must be stopped for a 20-minute break. Fatigue driving can lead to traffic accidents, with severe cases posing life-threatening risks. Definition of fatigue driving: When a driver operates a vehicle continuously for more than four hours without taking a break of at least 20 minutes, this constitutes fatigue driving. Requirements for fatigue driving: To enhance the detection of fatigue driving, traffic police authorities mandate that commercial vehicles such as large trucks and long-distance buses must be equipped with tachographs by their operating companies, along with GPS positioning and monitoring systems.

What kind of driver's license is required for an electric four-wheel vehicle?

The "Road Traffic Safety Law" stipulates that four-wheel electric vehicles not only do not have relevant driver's licenses but are also not allowed on the road. Currently, the so-called "four-wheel electric vehicles" driving on the roads are unregistered and considered illegal. Legal regulations: The "Road Traffic Safety Law" stipulates that motor vehicles refer to wheeled vehicles driven or towed by power devices, used for transporting people or goods on roads, or for specialized engineering operations. Definition of non-motorized vehicles: Non-motorized vehicles refer to vehicles driven by human or animal power on roads, as well as vehicles with power devices but whose maximum design speed, unladen mass, and dimensions comply with relevant national standards, such as electric wheelchairs for the disabled and electric bicycles. According to this legal concept, so-called "elderly scooters and four-wheel electric vehicles" on the road fall under the category of motor vehicles.

Is it safe to drive on the highway with a tire pressure of 2.6 in winter?

The issue of driving on the highway with a tire pressure of 2.6 in winter. The normal tire pressure range for most cars is between 2.3-2.5, and in winter, the pressure can be increased by 0.2-0.3. The following is an introduction to tire pressure: The importance of tire pressure: Tire pressure, strictly speaking, refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and damage to the engine will lead to the end of the car's life. Similarly, tire pressure is the blood pressure of the car, and the level of tire pressure plays a crucial role in the performance and power of the car. Precautions for tire pressure: While driving, pay attention to the sound of friction between the tires and the ground, feel the cushioning force when driving over uneven roads, and notice if there are any changes in acceleration when stepping on the gas compared to normal conditions. These are all experiences accumulated over time. Normally, check and replenish the tire pressure at a professional tire repair shop every week.
