| Abstract: | This paper presents a method of frequency analysis of intake pressure for internal combustion engines. The frequency spectra of intake pressure for internal combustion engines with different cylinder numbers are investigated. The relationships between the frequency spectra of intake pressure and the volumetric efficiency are discussed. The results show that the volumetric efficiency of engines can be improved by the resonant intake system. |
