|Chinese to English: Internal Engine Combustion|
|Source text - Chinese|
内燃机经历三次技术革命：上世纪20年代，机械泵出现很大程度改 进了内燃机的燃烧过程；上世纪50年代，废气涡轮增压器使内燃机动力 性、经济性显著提高；上世纪70年代，两次石油危机先后爆发，就在这 时，内燃机迎来了智能化革命，燃烧技术再次发生质的飞跃。

The internal combustion engine technology is a multidisciplinary science study. The technology was developed base on the basic science on sound, light, heat, electricity, and magnetism.
The technology went through three technological revolution:
- improvement of combustion process with larger mechanical pump size in the 1920s
- higher economical production with the introduction of turbocharged engine power allows in the 1950s
- intelligent technology revolution in the internal combustion engine, which has led to a qualitative leap in the combustion during 1970s, when two oil crisis has erupted at that time.
