一台发动机的功率和效率的高低,取决于燃烧性能的好坏。大家都知道,柴油机是压缩点火,因此,必须具有足够的压缩力、合理的燃烧室、燃油雾化良好、燃油分布均匀、空然比(喷入燃烧室中的燃料与空气的比值)合适。否则,会影响发动机的燃烧性能。 但是,在实践工作中还要出现如下病 The power and efficiency of an engine depends on the performance of the combustion. As we all know, diesel engine is compression ignition, therefore, it must have sufficient compression force, reasonable combustion chamber, good atomization of fuel, uniform distribution of fuel, air ratio (fuel injected into the combustion chamber and air ratio) appropriate. Otherwise, it will affect the combustion performance of the engine. However, the following diseases occur in practice
