Effects of methanol mass proportion on combustion characteristics of premixed charge induced ignition for explosion-proof diesel engine
摘要
Abstract
Based on the strengths of polyoxymethylene dimethyl ethers (PODEn), F-T diesel and methanol, improving the energy conversion efficiency, an experiment was undertaken on modified CY25 diesel engine to study the effects of different methanol mass proportion on combustion characteristics with methanol/PODEn, methanol/F-T diesel premixed charge induced ignition mode. The results showed that with increasing methanol mass proportion, brake specific fuel consumption of methanol/PODEn combustion mode was increased and the effective thermal efficiency was decreased;but methanol/F-T diesel combustion mode is in the opposite trend when the methanol mass proportion is less than 60%. With increasing methanol mass proportion the combustion phase delay. In the maximum pressure and the maximum rate of instantaneous, the biggest ascending range of methanol/PODEn combustion mode reach 9.5%and 142% compared with original machine. And the biggest ascending range of methanol/F-T diesel combustion mode reach 4.24%and 99.7%.关键词
