s spark plug action and working principle animation demonstration

1. Spark plug, commonly known as fire nozzle, its function is to send high-voltage wires The pulsed high-voltage discharge breaks through the air between the two electrodes of the spark plug and generates electric sparks to induce the mixed gas in the cylinder.

2. Discharge between electrodesThe phenomenon generates sparks. Gasoline engines generate power through the timely combustion of fuel and mixed gases, but gasoline as fuel is difficult to spontaneously ignite even in a high-temperature environment. To make it burn in time, it is necessary to ignite with "fire". The spark ignition mentioned here is the function of "spark plug".

3. Spark plug, commonly known as the nozzle, its function is to discharge the pulsed high-voltage wire from the high-voltage wire, break through the air between the two electrodes of the spark plug, and generate electric sparks to induce the mixed gas in the cylinder. Basic conditions for high-performance engines: high-energy and stable sparks, uniformly mixed gas, and high compression ratio.

4. The working principle of the automobile spark plug is that the electric plate of the spark plug is a mixture of air fuel in the gas cylinder through the power generation point repeatedly. At this time, the ignition systemOther parts generate timed high-voltage electric pulses, forming sparks and exploding, providing the energy needed for engine power output.

Briefly describe the working process of the four-stroke gasoline engine?

1. In summary, the four-stroke gasoline engine completes a working cycle through the four journeys of intake, compression, combustion and exhaust.During this period, the piston moved four strokes back and forth between the upper and lower stop points, and the crankshaft rotated for two weeks accordingly.

2. The working process of the four-stroke gasoline engine: during the intake journey, the intake valve is open and the exhaust valve is closed. The piston moves from the upper stop point to the lower stop point, and the combustible mixture formed by the carburetor is sucked into the cylinder; in order to make the combustible mixture inhaled into the cylinder burn quickly to generate greater pressure, the combustible mixture must be compressed before combustion.

3. The strokes are: intake, compression, combustion and exhaust. After completing these four processes, the engine will run for two weeks. The process is as follows 1. The piston starts at the top, the air intake valve opens, and the piston moves down to inhale the oil-gas mixture 2. The piston moves to the top to compress the oil-gas mixture, making the explosion more powerful.
