柴油发动机燃烧的基本条件,是气缸中的空气被压缩后产生高温将燃油点燃,其压缩性能决定柴油发动机的主要工作指标。目前,我国柴油发动机普遍存在着压缩比偏低,影响柴油发动机的燃烧过程,将造成柴油发动机动力、经济性能下降,因此,适当提高压缩比是改善柴油发动机燃烧的首要条件,就是说,尽量减少压缩后燃烧室的体积,是提高压缩比的主要措施。 那么如何提高压缩比呢?根据技术改造的
The basic conditions of diesel engine combustion, the air in the cylinder is compressed to produce high temperature to ignite the fuel, the compression performance of diesel engines determine the main work indicators. At present, the compression ratio of diesel engines in our country is generally low, affecting the combustion process of diesel engines, which will result in lower power and lower economic performance of diesel engines. Therefore, proper compression ratio improvement is the first condition to improve the combustion of diesel engines, that is, to minimize After the compression chamber size, is to improve the compression ratio of the main measures. So how to improve the compression ratio? According to the technical transformation
