内燃机能量贬值原理

Principle on Energy Depriciation in Interal Combustion Engine

通过对不同类型热力发动机功率传输机构的研究分析和对曲柄连杆机构扭矩传输公式的推导,提出了一个新的理念——"内燃机能量贬值原理",进而指出了内燃机功率的大小直接与功率传输机构的结构型式有关,提高最高燃烧压力时的力臂系数,是改革传统内燃机,提高其升功率、降低比油耗、减少能量贬值的重要途径和方法。另外,还设计了一种简易试验装置,实验结果定性地证明了"内燃机能量贬值原理"的正确性。

The paper proposes a new concep of Energy Depreciation in Internal Combustion Engine on the basis of analysis on power transmission mechanism for different thermal engine and torque transmission formula of crank and connecting rod, proposes the relationship between engine power and structure power transmission mechanism and gives a conclusion that it is the better solution to increaces coefficcient of moment arm as to modif the internal combustion engine, update pwer, decrease specific fuel consumption and energy depresciation. A simple test equipment is designed, the test result shows that the principle on Energy Depreciation in Internal Combustion Engine is reasonable.
