What does deflagration mean?

Question 1: (Automobile engine) What is deflagration? What is deflagration? Deflagration and deflagration are a concept. After the spark plug is ignited, before the flame arrives, the remaining mixture will ignite itself without being ignited. This combustion is deflagration, that is, detonation. Spontaneous combustion is obviously the phenomenon that fuel burns itself without ignition. So, in a nutshell, spontaneous combustion causes deflagration.

1. Knock: It is the most important abnormal combustion of gasoline engines, which mostly occurs when the compression ratio is high. When it appears, the engine will produce high-frequency metal knocking, so it is also called cylinder knocking. The engine power of 1 increases slightly when the knock is slight, but decreases when it is serious, resulting in unstable operation and serious engine jitter, which will make the engine overheat and emit black smoke.

1. 1 In short, during normal combustion, the flame starts from the ignition center (spark plug) and spreads to the whole combustion chamber at a speed of 30-70m/s. ..

2. deflagration: before the flame arrives, due to some reasons (such as carbon deposition or low fuel grade, etc. ), multiple points in the cylinder catch fire at the same time, local pressure and temperature rise sharply, pressure wave oscillates at high frequency in the cylinder, and the flame propagation speed can reach 1000m/s during strong detonation.

Question 2: What is deflagration? The popular point is that the mixture is ignited by a spark plug when it burns in the cylinder. The normal combustion process is that the mixture near the spark plug is ignited first, and then diffused outward layer by layer.

If deflagration occurs, the mixture will be separated by some unburned mixture, so that the mixture far from the spark plug and the mixture near the spark plug will burn at the same time. This will produce obvious knocking sound, damage the engine and have a negative impact on power, so it is not allowed. Deflagration is directly related to the ignition advance angle.

Question 3: What does the network term explosion mean? Players of League of Legends explained that if the wind generally means hurting the leaderboard. .

Question 4: What is deflagration, what is its cause and what is its harm? An explosion propagating at subsonic speed is called deflagration. It is a phenomenon that the combustible mixture accumulated in the furnace burns at the same time, which makes the pressure on the flue gas side of the furnace suddenly rise. In severe cases, the pressure generated by deflagration can exceed the allowable value of the design structure, resulting in the destruction of water wall, rigid beam, roof and furnace wall. There must be three conditions (namely, three elements of deflagration) for deflagration to occur, all of which are indispensable. One is the accumulation of fuel and combustion-supporting air; Second, the mixture of fuel and air has reached the concentration of deflagration; Third, there is enough ignition energy. How to avoid the accumulation of fuel and combustion-supporting air during boiler start-up, operation and shutdown is the key to prevent the furnace from deflagration. Deflagration occurs in an instant, and the flame travels very fast, reaching hundreds to thousands of meters per second. Spherical flame spreads in all directions and burns out in a few percent to a few tenths of a second. This means that the fuel is ignited at the same time, and the smoke volume suddenly increases, causing great smoke resistance, and it is too late to escape and explode.

Question 5: What is a large-scale explosion? What does explosion mean in lol? One is the injury explosion, and the injury is off the leaderboard. Hero, the output is extremely high. Second, the outbreak of the situation means that there has been an irreparable team battle that affects the outcome.

Question 6: What do you mean by the most popular online language? The score of 100 comes from a joke that a person met Aladdin's magic lamp in the desert. The magic lamp gave him three wishes, and he said excitedly, it's amazing! Then * * * exploded. Bunker is the homonym of explosion.

Question 7: What does BIGBANG mean? One of the hypotheses of the origin of the universe: at first, the universe was very small, and there was almost a point smaller than the size of the nucleus, called singularity, but it contained a lot of heat energy. Until the end, the singularity could not accommodate such heat, and the big bang happened. Some elementary particles were formed by the energy of the Big Bang, and these particles gradually formed various substances, energy, space and time in the universe under the action of energy. At this point, the Big Bang model has become the most convincing theory of the universe. However, so far, the Big Bang theory still lacks the support of a large number of experiments, and we still don't know the picture before and after the universe began to explode.
