Description

本発明は超音波励起装置に関し、具体的には超音波燃料励起装置に関する。 The present invention relates to ultrasonic exciters, and more particularly to ultrasonic fuel exciters.

エンジンはある燃料を使用して動力を生成する機械装置であり、すなわち燃料を化学エネルギーから熱エネルギーに変換して、最後に機械的エネルギーに変換する機械である。
エンジンの効率は機械効率と熱効率という二つの指標がある。ここで、熱効率は燃料が燃焼した後に仕事をするための熱量と生成可能な総熱量との比を指す。燃料が完全に燃焼して生成された熱量は、一部がエンジン冷却系に持ち去られ、一部が排気ガスと共に排出され、少量の熱量のみが仕事に用いられる。従来の内燃機関の熱効率は低く、一般的に４ストロークガソリンエンジンの熱効率は２０％～２５％であり、高性能のエンジンであっても熱効率が３０％未満である。 An engine is a mechanical device that uses some fuel to generate power, i.e. a machine that converts the fuel from chemical energy to thermal energy and finally to mechanical energy.
There are two indicators of engine efficiency: mechanical efficiency and thermal efficiency. Here, thermal efficiency refers to the ratio of the amount of heat required to do work after the fuel is burned to the total amount of heat that can be produced. The heat produced by the complete combustion of the fuel is partly carried away to the engine cooling system and partly exhausted with the exhaust gases, leaving only a small amount of heat to be used for work. The thermal efficiency of conventional internal combustion engines is low, typically 20% to 25% for four-stroke gasoline engines, and less than 30% even for high performance engines.
