油氣需要用火花塞點燃，但環(huán)境溫度過高，溫度過高壓力也會使油氣自燃。自動攪拌車燃燒室壓力高。如果使用低抗沖擊性的燃油，很容易爆震。其次，自動攪拌車的混合物在燃燒室內(nèi)燃燒，火焰以“波”的形式從著火點向周圍擴散，油氣從著火到完全燃燒需要很短的時間。爆震的主要原因如下：
The oil and gas need to be ignited with spark plugs, but the ambient temperature is too high, and the high temperature and pressure will also cause the oil and gas to spontaneously ignite. The pressure in the combustion chamber of the automatic mixer is high. If the fuel with low impact resistance is used, it is easy to knock. Secondly, the mixture of automatic mixer truck burns in the combustion chamber, and the flame spreads from the ignition point to the surrounding in the form of "wave", and it takes a very short time for oil and gas to burn completely from ignition. The main causes of detonation are as follows:
點火角太早：一般爆震是由于油氣在燃燒室點火后火焰擴散不完全，遠處未燃燒的油氣因高溫或高壓自燃，火焰與規(guī)則燃燒火焰碰撞產(chǎn)生巨大壓力，使發(fā)動機產(chǎn)生異常爆震。
Ignition angle is too early: generally, detonation is due to incomplete flame diffusion of oil and gas after ignition in the combustion chamber. The unburned oil and gas in the distance spontaneously combusts due to high temperature or high pressure. The collision between the flame and the regular combustion flame produces huge pressure, which makes the engine produce abnormal detonation.
自動攪拌車發(fā)動機積碳過多：為了使活塞在上止點壓縮結(jié)束后進入動力沖程后立即獲得動力，通常在活塞達到上止點狀態(tài)前點火。
Excessive carbon deposition in the engine of the automatic mixer: in order to obtain power immediately after the piston enters the power stroke after the compression of the top dead center, it is usually ignited before the piston reaches the top dead center state.
空燃比不準確：自動攪拌車燃燒室積碳過多，不僅會增加壓縮比，而且積碳表面會產(chǎn)生高溫，導致自動攪拌車水泥機爆震。
Inaccurate air-fuel ratio: excessive carbon deposition in the combustion chamber of the automatic mixer will not only increase the compression ratio, but also produce high temperature on the carbon deposition surface, resulting in the detonation of the cement machine of the automatic mixer.
燃油辛烷值過低：過稀的燃油空氣混合比會使燃燒溫度升高，而燃燒溫度會使小混合器的發(fā)動機溫度升高，當然很容易爆震。如果點火太早，當活塞仍處于壓縮沖程時，大部分油氣將燃燒。此時，未燃燒的油氣將承受巨大的壓力而自燃，引起爆炸。
The octane number of fuel is too low: too thin fuel air mixture ratio will increase the combustion temperature, and the combustion temperature will increase the engine temperature of the small mixer. Of course, it is easy to knock. If the ignition is too early, most of the oil and gas will burn when the piston is still on the compression stroke. At this time, the unburned oil and gas will bear great pressure and spontaneously ignite, causing an explosion.
The main reason for the oil burning and knocking of automatic mixer is the above related content. I hope I can help you. For more details, please come to our website http://www.fxsgujg.cn Look!
