| Abstract: | The significant design parameters of large low speed marine diesel engine of dual combustion cycle,i.e.its nominal compression ratio and effective compression ratio~(1]),and also the differences of ideal adiabatic and actual compression pressures~(2]) are studied in the paper.By measuring clearance volume precisely the comparison and analysis of ideal and actual compression pressures are carried out.By using correct design parameters of engine it is discussed how the maximum effective compression ratio can be kept to reach engine maximum design compression pressure so as to enhance engine output normally. |
