油气需要用火花塞点燃,但环境温度过高,温度过高压力也会使油气自燃。自动搅拌车燃烧室压力高。如果使用低抗冲击性的燃油,很容易爆震。其次,自动搅拌车的混合物在燃烧室内燃烧,火焰以“波”的形式从着火点向周围扩散,油气从着火到完全燃烧需要很短的时间。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:
点火角太早:一般爆震是由于油气在燃烧室点火后火焰扩散不完全,远处未燃烧的油气因高温或高压自燃,火焰与规则燃烧火焰碰撞产生巨大压力,使发动机产生异常爆震。
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.
自动搅拌车发动机积碳过多:为了使活塞在上止点压缩结束后进入动力冲程后立即获得动力,通常在活塞达到上止点状态前点火。
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.

空燃比不准确:自动搅拌车燃烧室积碳过多,不仅会增加压缩比,而且积碳表面会产生高温,导致自动搅拌车水泥机爆震。
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.
燃油辛烷值过低:过稀的燃油空气混合比会使燃烧温度升高,而燃烧温度会使小混合器的发动机温度升高,当然很容易爆震。如果点火太早,当活塞仍处于压缩冲程时,大部分油气将燃烧。此时,未燃烧的油气将承受巨大的压力而自燃,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.
